Wings on the Wind

The Marine Science Centre at Ponce Inlet held it's 4th annual Wings on the Wind Festival last weekend.

In November the Centre holds an Open House that highlights it's coastal wildlife rehabilitation programme. Injured turtles, manatees and seabirds are provided with medical care and a safe place to recover from whatever ails them.

There were quite a few sea turtles in tanks recovering in the Sea Turtle Hospital ICU Ward. Some big, some small. This one was the biggest.

An assortment of birds of prey were on show. All of these birds had been found as orphaned fleglings, unable to care for themselves, so volunteers have stepped in as substitute parents.

This Harris's Hawk had been raised by hand since he fell out of his nest at 14 days old. He was flying free but always returned to his handler's gloved hand on command. While we watched, he caught a lizard and greedily gobbled it up.

An Eastern Screech Owl sat patiently on her handler's glove waiting for a tasty snack.

This is Priscilla, an American Kestrel. This bird is the smallest falcon ocurring in North America.
But the highlight of the afternoon is the bird release. This year there were three birds who had recovered from their injuries enough to be released back into the wild, a laughing gull, and two brown pelicans.
The birds arrived at the beach in two animal carriers, covered in a cloth. As the coverings were removed, the gull (in the smaller carrier) became very anxious to leave. "Let me outa here!"

The gull didn't waste any time on a polite "Goodbye" or "Thankyou", as soon as the door was opened he was off!

And the pelicans followed suit, making it down the beach to the water breaking the world land speed record for pelicans. It was all over in a matter of seconds. A little different from the stately decorum of last year's release.

Three more beautiful seabirds are healthy and back where they are supposed to be thanks to the good people at the MSC.

Sea Turtle Nest N201

Soon after we first arrived at Ormond Beach, I noticed this turtle nest had been marked and tagged.
The turtle nesting season in Volusia County ends on October 31.

The total count for 2008 was 649 nests on this part of the Florida sea coast, mostly of Loggerhead turtles.

This nest was laid on August 23 2008, and was numbered N201 and dated by the Beach Turtle Patrol. Incubation takes approximately 55 days, so the baby turtles should have hatched a few days before we arrived.

The female turtle lays 85 - 110 eggs in the sandy nest, which she digs with her hind flippers. After she covers her eggs, she returns to the sea, leaving her babies to take care of themselves and find their own way to the ocean.

I walked past the nest site most mornings but didn't see any sign of hatching. No baby turtle footprints to be seen. Turtle Patrol people wait at least 70 days before investigating if there has been a successful hatch.

A couple of days ago Turtle Patrol dug the nest site.

They found 108 unhatched eggs, some with partially developed embryos. Turtle Patrol told me that the nest probably got overwashed too many times by the high tides.
The odds are stacked against baby turtles surviving the hazardous journey to adulthood. First they have to make their way from the nest to the sea, many of them are disoriented by beach lighting and head in the wrong direction.
Then they have to avoid being swept onto beaches by storms or high tides, or becoming dinner for a larger hungry sea creature.
Only about .01% of the hatchlings survive to return to the same beach as adults to lay their eggs.
Better luck next time, Mama Turtle.
