Turtle Hatchings


I know, I know, I said I was done with the turtles and it is true that new tractor trails are getting to be a rare sight on the beach in the mornings but last night was a busy one none-the-less as several of the nests have hatched and there are miniature tracks, no more that a few inches across, weaving across the sand in all directions.

  
The theory behind a hatching is that a couple of days before the babies break out of the nest they start emerging from their eggs underground and gathering in a group, still safely buried in the sand.  Once all (or most at least for there is no time to wait for the tardy) are free of their soft shells they erupt from the nest in one energetic burst and go hell for leather down to the water’s edge, tiny flippers a blur of activity.  They should instinctively know which direction to take as the breaking waves on a dark beach will be the brightest point around.  To ensure that this is so, residents in houses lining the back dunes must turn off or black out any lights facing the ocean to prevent confusing the little ones and in our area at least the residents are very good at following this practice.

This morning we came across a perfect example of how to escape from a nest and all the tracks lead down to the water.  Ten out of ten for this batch of babies. 


However this is not always the case, especially in nests further away from the shore.  Here there seems to be a certain amount of confusion amongst the turtles when they finally see starlight.  Often a nest will have tracks coming out at all angles as if the hatchlings were in such a hurry to escape that they beetled off in whichever direction they happened to be pointing when they emerged.   


A few minutes of thoughtful reflection at this stage and it could all have ended so differently.  As it is the hapless ones who head towards the back of the beach usually come to a bad end, their tiny tracks ending abruptly (picked off by a bird?) or more sinisterly ending where a ghost crab’s trail begins. 


The crabs are not kind to their prey, snipping off one front flipper to immobilize the victim and rushing around to see if they can catch some more before dragging them all down into their lures.  

One thing is certain; by the time the sun comes over the horizon and slowly takes over from the surf as the brightest point on the beach all the newly hatched turtles have gone somewhere – ocean, crab, bird or raccoon – and all that is left of them is their tracks.

Now I am done with the turtles.

Chat soon

It was all excitement on the beach this morning, my leisurely stroll upgraded by a feast for the eyes.  September is the time the large shoals of fish pass by along this coast line and today they were running.  There was action from the shoreline to the far horizon as the dawn feeding frenzy was underway.  The first clue was the silvery necklace of small fry decorating the shoreline, glittering in the early sunshine.  These poor creatures are the bottom of the food chain, born to be eaten, and a continual supply were being chased onto the incoming waves by the jacks hunting them; surfing in to their doom.  Once washed onto the beach they flapped frantically to maneuver themselves back into the water but most ended up slowly drying tantalizingly close to the ocean.  One walker was gamely trying to throw the small fish back into the water one by one but the odds of nature were overwhelmingly against her and she had to accept defeat.  The seagulls wheeling overhead then swooped down to clean up so there was no chance of escape for the struggling fry. 

Things were no quieter in the water.  The surface boiled and swirled with the action taking place below and shoals of smaller jacks occasionally took flight as the snook prowled and attacked.  These larger predators have arrived in force and groups of them swirled in the waves a mere three feet from the shoreline, breaking the surface of the water with their spine-like dorsal fins and sleek long bodies.

Further out to sea the tarpon were gathering and one, under pressure from an unknown attacker, shot up into the air to reveal its powerful shiny body.  It was at least five feet long but we will call it six as this is a fishy tale.  And beyond these the sharks were prowling, so close to the surface that the fins could be seen breaking the water.  No foolhardy bathers were risking an early morning swim today.

Word of the fish had somehow spread and fishermen and women began to arrive hauling their rods and paraphernalia down the sand and making themselves comfortable on their upturned buckets or, for the more organized, beach chairs. It looks like there will be a lot of fish suppers in Vero tonight.

One lone green turtle track and nest had appeared overnight but no one was interested in that.   Turtles are yesterday’s news as today the fish have arrived.
