ΦCno22 First Hatch
ΦCno22 hatched today!! Owen sent this text message:
Cno22 H. 2 many 2 count, all 2 the sea. 0 at Dgh21.
One down two to go... three days left before O leaves Matala - although I'm sure they'll make it without his help, all three nests are (I think) well away from man made light sources.

Hatching News
Got a text message from Owen saying that ΦDgh21, the first nest I found, dipped yesterday... the surface of the sand above the nest has dropped, indicating that the eggs have started hatching and the hatchlings are making their way up to the surface, causing sand to collapse into the airspace around the eggs. With any luck someone will find tracks before the project winds up in Matala in a few days time. O texted me again to say that there are tracks this morning - I'm keeping my fingers crossed!

Red Beach - My Last Day (1.09.2003)
O and I woke early as the sky became light. We fanned the embers of the fire into life and breakfasted on a second helping of garlic bread, accompanied by butter-beans in tomato sauce, coffee and grapefruit juice before heading down to survey Red beach. Nothing unusual to be found; beech marten tracks running the length of the beach, crisscrossed with the snickerty tracks of Ghost crabs.
The survey complete we snorkeled for a while, the sea cooling us pleasantly as we drifted, watching shoals of fish flitting in the shallows. Small clouds of sand lifted and fell rhythmically along the ripples in the sea bed, driven by the circulating flows that form the incoming waves. Rays of sun played through the underwater world, swinging back and forth, refracted by the surface of the sea above.
It was almost 11am by the time we left and it was hot work slogging back up over to Matala, stopping off at the cave to pick up our gear. After a quick shower back at camp we treated ourselves to a cold Mythos in Zafiria. O read while I wrote my diary and uploaded a couple more days worth to the internet using one of the cafe's two net connected computers.
This was my last full day on Crete. Sadly O had to miss my leaving soiree, as he had to head over to Rethymno for a "Skill Share" meeting with the other Archelon coordinators. I sat up late with the other volunteers, listening to music and drinking cask wine at our camp table. We played backgammon and chatted well into the small hours.
So, my time in Crete in the Bay of Messara has come to an end, all too soon. I've thoroughly enjoyed myself - although the work has been at times exhausting, sometimes boring, in the main it has been thoroughly absorbing and truly rewarding, and inspirational on more than one occasion. I would recommend it to anyone who has an interest in the natural world and the fantastic creatures that we share our planet with.
I'll continue to update this site; in a few days I'll be putting some pictures up, and I'll be reporting on the progress of the nests I helped to locate. When Owen returns I should be able to give an overview of the Sea Turtle's nesting activity this year in the Bay of Messara.
AB Beach with Owen (31.08.2003)
My last morning survey on AB and a quiet one. Just one nest hatched, ΦAjk14. We found two diverging hatchling tracks, neatly avoiding a pit dug unwittingly by holdiaymakers, directly between the nest and the sea.
Rock dog joined us halfway through our walk down the beach and stayed with us until we met foxy and bouncy dog (a young grey dog with more than a little whippet in him) on our return back to the van.
In the evening O and I headed up into the hills again. As tomorrow is my last day I wouldn't normally have to do any shifts, but we volunteered to survey Red beach as the cave we planned to spend the night at is in a valley just behind Red beach.
The night was heavy and humid, haze slowly turning into low cloud as the light of the sun faded from the sky. We detoured onto the cliff tops on the way up to the cave, clambering out on to a rocky promontory between Matala bay and Red Beach. We dumped our packs with great relief, sweat pouring from our bodies. I dug out two cold beers we'd bought at the bakery on the way up and we sat and cooled very slowly, listening to the surge of the sea far below. Lights appeared and disappeared out to sea as fishermen went about their nights work. In the distance the lights of Kokkinos Pyrgos and Agia Galini twinkled in the warm, moisture laden night air. In places the lights resembled the smoldering edge of a stubble fire, a reddish orange glow pulsating in beads of light along the cost.
Our beers finished we shouldered our packs again and headed down to the valley where the cave is. The warm damp air showed no signs of lifting and we were drenched again by the time we reached our camp for the night. As it was so still we decided to sleep on the flat terrace outside the cave. O made a fire while cleared an area to sleep on and strung up the mosquito net.
Later, as we sat enjoying a glass of local wine (bought earlier in the day in Pitsidia, the proprietor filling our plastic bottles from a barrel) watching the flickering flames of the fire, thankfully the oppressive humidity started to clear. We feasted on the best garlic bread ever made, the cuts in the bread filled with feta, olive oil, garlic, oregano and chilli, then baked to perfection in foil on a flat rock in the centre of the fire. We both drifted off, replete, under the starry sky.
CD Beach with Suzy (30.08.2003)
A quiet day on the beach today. A bat flitted around the cliffs at the start of C beach as we set out; later swallows dipped and dived overhead as the sun began to rise. At the river mouth the egret stalked as usual, taking flight as we approached. A large hawk flew low over the reeds, searching for prey.
ΦDwx12 hatched again today. An informed Australian family found two hatchlings on their backs and shaded them to the sea just minutes before we arrived. As we approached they came over and explained what they'd found. Three of them were visiting a relative who lives in Crete and they were due to fly back today; I think they were delighted to have helped "save some turtles" before returning home. They even donated their beach mats for us to use to make nest shading. I was touched by their kindness and interest in our work.

The Lost Nest (29.08.2003)
No morning survey for me today, but I did do some beach work in the evening. Owen and I went to have another go at excavating ΦAop13R. When Owen and Griet had first tried to excavate it three days earlier they couldn't find it. We suspect someone dug up the nest about 5 days after it hatched.
Sadly we couldn't find it either. We dug a hole in excess of 3m in diameter but found not so much as a scrap of eggshell. What happened to the nest will remain a mystery.
After digging we drove up to Kokkinos Pyrgos to do a light survey, which involves measuring the intensity of light on the beach as a result of human activities - for example, tavernas and streetlamps. This stretch is particularly bad, registering the maximum light intensity on our scale all along the new road and up to the end of D beach where a hotel and a few tavernas spill light out onto the shore. This came as no surprise, as the hatchling tracks from nests on this strip show massive disorientation problems.
CD with Owen and Julia (28.08.2003)
Last night was one of the hottest and most humid since I've been here. All surfaces were sticky to touch and my bedding was damp. As we set off for morning survey the smell of wild oregano and other aromatic herbs assaulted our senses, carried by the thick, moisture laden air.
Two nests hatched last night; 1 hatchling from each. Sadly neither made it to the sea. At ΦCmn11 we found one dead, and at the other end of the beach at ΦDwx12 the tracks looped round and round then disappeared amongst human and dog prints.
As we passed the little estuary that separates C and D beaches Owen pointed out the solitary egret that lives here, stalking along in the shallows, almost heron like in its gait.
Julia and I excavated ΦDgh2UM, the unmarked nest Cat found 10 days ago. The egg chamber was slightly to one side of the centre of the cage; intially we dug in every direction except towards the egss (of course). Eventually we found them though - a really successful nest. 70 out of 86 eggs hatched, the remainder all apparently unfertilized, and no dead hatchlings to be found.
Technically today was my day off, but I asked to go on morning survey anyway. As a result Owen and I had the rest of the day off. We dozed for a while then had lunch at Zafiria's, then walked around the cliffs towards Komos. We were treated to spectacular views of the wind and sea sculpted landscape. Slabs of dazzling bleached limestone slope down towards the north, the southerly slab edges pushed up by geological forces and formed into overhanging scoops by the wind. Wild oregano grows abundantly on the clifftops; closer to the sea, hollows in the rock are filled with salt crystals. Fissures in the slabs are widened by the sea to form breathtakingly deep crevasses, the sea surging deep below.
Swallows dived around our heads as we rounded the cliffs and the nesting beaches came into view. We descended to the sea and swam, then sat and soaked up the last hour or so of sun as it sank towards the sea. We climbed back up before it reached the horizon and dined at "Mystical View", a taverna perched on the cliftop. The food was excellent and we were well satiated by the time we strolled back down to Matala in the darkness.
Revelry ensued - tonight was Julia and Amy's leaving celebration, which involved a tour of Matala's loud and tacky bars. I only made it as far as the first, the infamous Tommy's Music Bar, where I drank far too many of the complimentary Raki's before staggering home exhausted.

CD with Cat and Julia (27.08.2003)
As I approached the second nest we had to check today, ΦCmn11, I spotted a hatchling under the nest cage, on its back. It must have emerged from the sand only to fall (or was possibly pushed by one of its siblings) immediately on to its back - a rough break after five days struggling up through 0.5m of sand. I pushed sand up underneath it, flipping it over on to its front. After a slow start it seemed to gain confidence, heading steadily towards the sea.
Julia and I sat by the nest as Cat shaded the hatchling down to the sea. The sun was just below the horizon as it started its journey, illuminating the low lying cloud in progressively paler bands of pink. As we looked towards the sea a kingfisher appeared, hovering above the rockpools, then plummeting into the sea as it spied it next meal. I realised that I've started to take these idyllic moments almost in my stride. Returning home to the city in less than a week is going to be quite a shock to the system.
It wasn't until we reached the end of D beach that we encountered more turtle activity. ΦDvw9 hatched again - seven more to the sea. Not so much luck for the four that hatched from ΦDwx12. Even though the nest is well shaded, the tracks went crazy around the nest; at some point they had made it about half way down to the sea, but then two had gone back up to the nest, only to be eaten by a bird or a dog, and the other two had escaped over the low stone wall we had built between the end of the shading and the sea. One we found dead; the tracks left by the other disappeared before reaching the sea.
The biggest problems the hatchlings have at this end of D beach are primarily down to the new road - the compacted sand and the bright street lamps along the back of the beach.
CD with Chrissie and Amy (26.08.2003)
We were a little late starting this morning; somehow we managed to leave the morning survey bags behind. I waited at Kalamaki while the others returned to fetch them, watching the stars gradually disappear as the midnight blue of the sky slowly began to lighten. Once it was bright enough to see I walked the end of B beach to save Owen and Griet some time, since they have an excavation to do once they've finished the survey.
Chrissie, Amy and I set off round the bottom of the low cliffs that separate B and C beaches. We passed a squadron of a dozen or more dragonflies, zooming around in formation like minature biplanes, yet able to stop, hover or change direction in an instant, unlike our clumsy man made machines.
In sector Cmn I stopped to study some faint tracks; as I looked up I realised I was only 10m away from ΦCmn11 - it must have hatched again. It took us a while to make a reasonable estimate of the number of tracks - the sand is very gravelly here and I'm sure we underestimated. At least 12 made it to the sea; one we found dead half way down, possibly attacked by a bird.
At the other end of the beach ΦDwx12 had hatched again. It had not been shaded on its first hatch 2 days ago, 12 of the 16 that emeged then were disoriented and lost. We normally shade nests on the 43rd day after they have been laid, the minimum incubation period - this nest had hatched on the 42nd night.
This time, though, the shading had done its job and all 6 tracks went to the sea, sometimes bouncing off the low wall of pebbles built from the end of the straw matting shading down to the sea.
After the survey I went for a long, relaxing swim while we waited for our lift home. The sea was dead calm today - first I headed out towards Paxmadia islands (so called because they resemble a huge bathing elephant, its trunk stretched out along the surface of the sea), then floated on my back, motionless, cradled and rocked by the ocean, the sun warming my face as I gazed up into the flawless blue sky.
53 Nests (25.08.2003)
I wasn't on morning survey today, but good news - another new nest on A beach.
Red Beach with Amy (24.08.2003)
All quiet on Red Beach today. Each time I go I secretly hope that this will be the day that we see hatchling tracks streaming out of an unmarked nest, but no such luck.
CD beach with Owen and Cat (23.08.2003)
Sunrise was particularly beautiful on CD today; the first glow of light a bloody orange, illuminating the scarified cliffs on the faces of the distant mountains, normall obscured by haze; then a bright pinkish orange started to creep down the mountain tops, catching far off tin or glass roofs making them sparkle like jewels. The light then shifted slowly through a spectrum, turning yellow as the sun first left the clutches of the horizon, casting the wind sculpted beach into sharp relief, then through to brilliant white as it moved higher in the sky.
As we crossed into the Miltary base we noticed the sea daffodils are starting to come out. In a couple of weeks they will transform the back of C beach, covering it with their delicate scented blooms.
Not much to report in the way of turtle activity. The wind was fierce this morning, at times causing us to hunker down with our backs to the wind to escape the stinging blast of sand. Hatchling tracks left last night would be very difficult if not impossible to see on a day like today.
At ΦDno10 we saw a hatchling head poking out of the sand. Owen brushed a little sand over to cover its head and protect it from the sun. It was very hot last night, perhaps the reason this one hadn't continued up and out into the night.
We spent a long time collecting large rocks and bits of concrete to keep the nest shading at ΦDvw9 in place, the wind ripping vicously at the straw matting we use to shade the nest fro the streetlamps on the new road.
We completed our survey of D beach and headed home for a welcome shower to try and remove the sand glued to our bodies.
ABCD with Owen (22.08.2003)
We set off from camp at 05:45 as usual for MS today and had only gone a couple of yards when we discovered we had a flat tyre. As we tried to remove the wheel, one of the wheel bolts sheared off, leaving us vehicle-less. The only option was to walk to the start of A beach, start the survey from there and walk all four beaches. I volunteered to go with Owen; Julia and Cat promised to explain the situation to Jodie and hopefully arrange pickup for us from the end of D beach at Kokkinos Pyrgos.
We raced up the hill out of Matala trying to beat the rising sun and avoid having to walk so far in its full glare. As we descended towards Komos the tops of the surrounding mountains began to glow pink as the sun, still hidden, crept inexorably towards the horizon.
Not much activity to be found on AB; one nest, ΦAop13R looked as though someone may have dug it up. There was a large depression in the sand and three out of the four corner stones we use to mark the nest had disappeared.
We stopped briefly to grab croissants to eat as we walked and a spinach pie for later; sustenance for a longer than usual walk and a possible hitch home at the end.
As we crossed from the end of B to the start of C beach the wind freshened considerably, whipping the sand up into our faces. Again not much turtle activity to be seen. Predictably we got stopped by the military - they always seem to turn up when there's a long morning ahead.
At the end of D beach we saw the only evidence of turtles on CD today; a couple of hatchling noses poking out of the sand at ΦDvw9. This is quite common - they spend around five days working their way up from the egg chamber, then wait just below the surface for the temperature to drop (indicating nightfall) before they emerge. They may well be on their way tonight.
Our walk this morning made me think back to what it was like in the early days of the Archelon project. Aparently the team at the start was just a handful of dedicated individuals who would do the survey just as we had just done, hitch back to camp and open the information kiosk. Things are much more organised and formalised now, with everyone assigned through a rota to do the various jobs, such as kiosk shifts, slide shows, cooking, maintenance, excavations and of course the morning surveys.
Thankfully Jodie managed to get the car fixed up and picked us up, sparing us a hot hitch home at the end of a long walk.
Relaxin' (21.08.2003)
Very chilled day today - my day off (we get one every 10th day). Slept in, then after breakfast added the picture you see on the right to this website. You can find loads more great turtle pictures in the seaturtle.org image library. Made a chip pan for camp out of chicken wire purchased (with much handwaving and mutual lack of comprehension due to my very poor grasp of greek) from the hardware store in Timbaki.

Murder on Red Beach (20.08.2003)
Jodie was scheduled to survey Red Beach this morning, but was followed by a dodgy looking guy up the lonely path. When she stopped to let him go past, he hung back, so she wisely decided to turn back. Red beach is very isolated, walled off by cliffs with no habitation and nowhere to run.
I woke just after 8am and volunteered to go instead. I assumed I would be in no danger since (a) I'm male and (b) by that time people are starting to arrive there for a days secluded sun worship.
As I crested the top of the cliffs and Red Beach came into view, I could see that in actual fact no-one had yet arrived. Then, as I started the descent towards the beach I heard voices calling out. I couldn't makeout what was said; from the tone it sounded like when you shout "echo" to hear the echo come back off a distant valley side. A moment later, a single gunshot rang out, the sound bouncing off the encircling cliffs. At this point I got a little spooked... I approached the beach as silently as I could, half expecting to see a blood drenched gunman lurching down the beach.
Of course, the beach turned out to be empty. The gunshot was probably some local sheppard trying ot bag a rabbit for his pot. It certainly spiced up an otherwise uneventful morning survey though. All I saw were ghost crab holes and one ghost crab, scuttling along in the surf. I wathced it for a few minutes, marvelling at its ability to crouch and flatten its body to the sand as a wave struck, able to resist the powerful suck of the receding surf, continuing its journey once the wave withdrew.
In the afternoon Jodie and I excavated ΦAAa10. A very successful nest; 90 out of 117 eggs hatched, 77 hatchlings made it out of the nest on their own. We found 8 more still alive in the nest, which we reburied.
As we cleaned up after finishing , we were treated to a magnificent sunset; we stood side by side, knee deep in the crashing surf as the firey red disc sank into the darkening blue sea.
AB Beach with Owen (19.08.2003)
My first morning survey with Owen since last Tuesday. The first thing we found was a hatchling track from ΦBcd12, just below a Taverna. The shading had been blown down by the wind, and the hatchling had followed the lights of the Taverna out of the shading, under a couple of sunbeds and around a parasol to the back of the beach. After a minute or two searching we found it, heading rather slowly and uncertainly towards the sea.
Owen shepparded the hatchling towards the sea, shading it from the rising sun. I kept the dogs away, and managed to take a few pictures.
I should probably introduce the morning survey dogs. They live locally and have learnt that Archelon volunteers walk the beach each morning. They invariably turn up when we arrive and follow along. In descending order of size, they are: Rock dog - an Alsatian who loves to fetch rocks, which is a problem, since he often picks up the headstones we use to mark the nests. He also has a penchant for water bottles, which is inconvenient to say the least, especially when he decides to steal yours leaving you with nothing to drink during the 6km hike down the beach. Next we have foxy, a reddish dog of meduim size and uncertain parentage; finally we have bad puppy, probably the most popular of the three, a playful black puppy who recently had to be thrown clear when it tried to play with a hatchling.
While O patiently watched the hatchling down to the sea, bad puppy and foxy amused themselves by ripping up nest shading. Only Rock dog was close enough to present any danger. Fortunately (a) he responds quite well to instructions and (b) he is only really interested in rocks.
ΦAop13 hatched again today; two very clear tracks across the pristine white sand, straight to the sea.
As we approached sector Ajk I noticed several people sleeping on the beach - one guy actually on the beach proper and several more up on the back of the beach. A few yards past the guy on the beach was a set of female tracks, including something that looked very much like a camoflage. She had come back down over the up track, so it was difficult to tell exactly where the camoflage began and ended. We staked out quite a large area and continued on down the beach, leaving the search for the nest for our return journey back down the beach (to avoid potentially leaving stranded hatchlings further down the beach drying up in the sun).
We didn't find any more hatchlings but we did find another female emergence right at the end of A beach, looping up and round ΦAAa10. The last attempt looked more like a body pit than a camoflage, but we dug it anyway. The dry sand in this part of the beach is very deep, so it took some time, bulldozering mounds of sand back from the edge of the hole we were excavating with our hands. Rock dog joined in, digging his own hole a couple of meters away, which was helpful as I could push sand from our hole into his (to prevent it falling back in), to his obvious disappointment.
Having excavated down to the wet sand we probed the area carefully using one finger. When we found nothing, we dug down another finger depth and probed again, but still nothing so we mapped the attempt and returned to the other emergence in sector Ajk.
Almost immediately we located what looked like an egg chamber. The wet sand was harder here, and there was a clearly deinfed circular edge roughly 20cm in diameter. Owen probed but didn't feel the telltale "give", so we cleared sand a little further along and found what we assumed was another attempt at an egg chamber. Again, no give; a couple of inches away was a third attempt, and this time Owen's magic finger felt what we were searching for. We scooped out the soft sand and sure enough we found the gleaming white spherical top of the uppermost egg.
At this point I felt extraordinarily lucky. Three nests in three days would be great news even in the height of nesting season (June - July), but here we were in late August. It was almost as if the invisible hand of fate had orchestrated the sequence of events for my benefit.
So, I hve now helped to locate 4 nests. Todays is ΦAjk27, plus ΦCno22, ΦDgh21 and the unmarked nest I found, ΦDbc1UM.
CD Beach with Cat and Chrissie (18.08.2003)
Another nest today! In sector Cno, we found an easily identifiable camoflage. Our first guess (Cat's in fact) was much closer this time. We had only been digging for 10 or 15 minutes when Chrissie felt something - today she was the proud owner of what Owen calls the "Magic Finger". The egg chamber was easy to see, since the wet sand in this part of the beach is quite hard, so the edge of the hole leading to the egg chamber was clearly defined. This time both Cat and Chrissie joined in the crazy celebrations, leaping around like fools in my now established nest dance, although it is quite possible that they were just humouring me. The code for our new nest today is ΦCno22.
On the military section of the beach we bumped into a greek couple, presumably ex-army (a lot of retired army personnel use this part of the beach - the army has sunbeds, shades, showers and a clubhouse on the beach). Owen and I had met them a couple of days ago when we excavated ΦDbc1UM. They asked us lots of questions about the turtles and went on to tell us all about their daughter living in London; a really geuine and friendly pair.
We shaded one of the nests due to hatch soon; it is right in the middle of the army sunbed area, close to the lights of the clubhouse at the back of the beach.
We also shaded ΦDvw9, due to hatch in a few days time, sweating in the late morning sun to find rocks and slabs of concrete to build up around the nest. There are street lamps that run all along the new road at the back of the beach in this section.
The found female tracks on AB beach too today, but no nest. I'm doing morning survey on AB tomorrow with Owen, so maybe we'll be lucky enough to find a third nest in a row...

CD Beach with Cat and Amy (17.08.2003)
All seemed quiet on the beach today until we reached sector Dgh, where we spotted female tracks, and what looked as though it could only be a camoflage - a 2.5m section of the track obscured by thrown sand. There was the outline of a body pit at the entrance to the camoflage - possibly where the nest itself was, but we couldn't be certain. Cat made a guess at the location of the egg chamber and (after marking out the area in which the egg chamber could be located) started to dig and probe the sand, searching for the telltale "give" which occurs when you push sand into the air space around the eggs. After 3/4 hour we had dug a large hole, 1.5m long, 0.5m deep and 1m wide, and still no nest. I was determined to keep digging until we had exhausted all possibilities, I felt so sure that this time we had found the real thing.
As we worked towards the end of the camoflage, I was probing the wet sand when I suddenly felt something. My heart lept - the sand really felt as though it had given way. I probed the surrounding area to check it wasn't just a patch of softer sand, but no. With my heart in my mouth I carefully dug down in the spot where I had felt the "give", gently scooping out handfuls of sand. Suddenly, I glimpsed something bright white; maybe just a small white pebble... with trepidation first I brushed away sand with one fingertip, then bent to blow it away. There was no mistaking it now, it was an egg - we had found the nest!
After carefully brushing a little sand back to cover the top of the egg, I'm only slightly embarassed to admit that I danced, whooped and generally made a fool of myself. My joy was unconfined. I must have excavated 6 nesting attempts in the last couple of days and I had begun to think I was never to find a nest, but finally here it was.
We took the first measurement, the depth of the egg chamber. Only when I went to record it did I discover that in my enthusiastic digging I had buried the morning survey book in the sand. Cat fell about laughing as I searched through the quite considerable mounds of sand. Thankfully it didn't take too long to locate.
We finished the measurements and set off again down the beach. For the second time during my stay here I would be unshakeably happy and optimistic for the rest of the day.
Further down the beach we found another emergence. As we stood studying the tracks an army jeep zoomed up and we were called over for an ID check. Several phone calls and radio conversations later we were allowed to go back to the tracks. We found no nest; it seems likely that this was the same female making an earlier attempt before finding a spot to her liking.
The total nest count for Messara Bay this year now stands at 48, not far from the average of 50, which we're hoping we'll exceed.
ΦDpq6 hatched again today; a solitary track lead from the nest to the sea.
The new nest we found today was given the code ΦDgh21.
CD Beach with Ciaran and Amy (16.08.2003)
Another action packed morning today. ΦBtC11 hatched again; two tracks, one to the sea, and one hatchling on its back. I flipped it over and it didn't take long to find its way down. As I glanced up from watching its progress, I caught sight of female tracks just a couple of yards away.
Ciaran and Amy staked out the last attempt as I watched the hatchling into the water, then we all dug. And dug. And dug. For an hour and half we laboured; the attempt had looked more like a camoflage than anything I'd seen so far, and we all felt that this could well be a nest. By the time we stopped we had moved a huge quantity of sand, and my arms and back were aching. Frustratingly, we found nothing.
Its fun to speculate on on what might have happened there last night; the female tracks came up, around the existing nest and back down the other side. Did she see the hatchlings emerge? Did she lumber past unawares, and inadvertantly flip one hatchling, one twentieth her size and quite possibly one of her own childeren (females nest 2-3 times during the season, often in very close proximity to their last nest), on to its back? Normally the mother will never see her offspring; maybe, just maybe, this was a rare chance encounter.
Just a few hundred yards further down the beach ΦCab8 hatched again, another 5 safely to the sea.
On D beach (which is part of the military base) we found another female track; no sign of a camoflage, just three body pits; we dug the last, but nothing to be found.
A little further on we found another emergence - in all probability the same female making another attempt. This time she had gone a good 30 - 40m from the sea, way up onto the top of the dunes. As we studied the tracks 2 military jeeps zoomed towards us across the airfield. 6 soldiers jumped out, some armed with automatic rifles. They beckoned us over; we explained we had permission to walk the beach every day, but nonetheless we were treated to a ride down to the security office so they could check our details. Everything checked out, and they were kind enough to drop us back where they had picked us up. We found no nest; possibly an abandoned egg chamber - we found lots of roots and sticks at the bottom of the hole she had dug. All in all it was a long survey today; we left at 05:35 and got back to camp nearly 8 hours later, just before 1pm.
Later in the day O and I excavated ΦDbc1UM, unmarked nest I found. As we began to clear sand the military turned up again. Yet again we were trundled off to the security office, despite the fact that one of the soldiers had been in the patrol we met in the morning. This time we were there for less than a minute; I think the security officials recognised me from the morning.
We had to work quickly to complete the excavation before the sun sank into the sea. The eggs were quite tightly packed; we found quite a few dead hatchlings and about 10 "pipped" - the hatchlings had managed to break partially out of their egg before they died. We also found a few oddities; three elongated eggs (they are normally spherical, the size and shape of a table tennis ball - the shells are soft though, so that they don't break when they are laid), and two pairs of twins. The first pair contained one embryo in the early stage of development, the other much larger in the late stage. The second pair were both in the very early stage, about 1cm in length. All in all there were a good number of hatched eggs (55), of which 47 had made it out of the nest, so a reasonable success.
