Turtle Patrol of 18 May; 6:10 am!

OK, so I admit 6:10 am is a lovely time to be on the beach (although mini me is still in bed at that hour!) . . .

. . . and there are plenty of fisherman at sea and a few beachcombers about.

Sunrise about 1 1/2 hour later here than in UK at the minute. Turtle patrols start 1/2 hour before sunrise.

Me out in the boat to Shell Key (uninhabited island bird sanctuary) and hubby in the jeep at Pass-a-Grille (barrier island) with Turtle Joe - all of us scouting the beach for any signs of loggerhead turtle nests.

Pink roseates swishing water for food
Nothing but human footprints on Shell Key, however, just being out on the water with Bruno was a real treat. The bird life, as you would expect, was superb with about six roseates sighted (sorry sis).


Blue Heron & friends
My point 'n shoot camera doesn't really do it justice, but here's a peek - bonus pelican flying overhead. This juvenile great blue heron caught a fish whilst we briefly jumped off the boat to check a previously found nest - the heron swallows the fish 'head first' to be sure it goes down.



False crawl

Back on sandy land in the jeep, what does hubby spy but ... first a solitary manatee -- spotted just off the coast -- then a 'false crawl' (when the mamma turtle is spooked and returns to the sea without laying any eggs); this needs to be raked out to avoid any confusion.  And then - yes tracks leading to a nest! Speculation is turtle tracks may be to turtles as unique as fingerprints are to us.

One has to locate the actual egg cavity or 'clutch'.  This isn't always as simple as it seems and we try not to dig up the eggs. The nest can only be touched by a 'permit holder.'  Here the sand is quite hard and the eggs are just below the surface (near to surface = warmer =  lots of females will hatch from this nest).

Turtle eggs look a bit like ping pong balls










Next the nest has to be triangulated with measurements from the mean high water mark and from the vegetation line; GPS coordinates are also taken.

Then it is time to stake and mark off the nest.  Job done for today.

    1. Ah, well here mainly hatch at night and cannot use flash photography ... so harder to get good shots. Try Mini Me's post of 23 August 2014 to see some hatchlings going to the sea.

  2. It looks fabulous and worth the pain of getting up early (bet the coffee tasted great afterwards ;) )
    Can't wait to hear aboutthem hatching and running to the sea..... how long do we need to wait?

  3. Coffee mumm. 45-60 days to hatch, so early to mid July. They will likely be mainly girls as warmer sand (and they are near the surface!) makes girls and cooler sands (ie deeper in nest) makes boys.
