Shorebirds
and Sea Turtles.
Shorebirds.
It is always fun to watch the plovers and sandpipers on the beach dashing
along the receding waters to
dig out a juicy morsel before the next wave approaches. Others, like the
pelican and terns, dive into the water to catch their meals while some
of the big herons wait for the fishermen to throw them something.There
are a large number of species of shorebirds on the beaches of Englewood
sharing space with us, such as the American Oystercatcher, Black Skimmer,
Least Tern along with the Plovers that nest on the beaches.
From
February 1st. to the end of August is the breeding season for these shorebirds
and there are certain areas in Stump Pass State Park, as well as on Palm
Island, that are roped off to provide a protective space for the breeding
adults.

The birds avoid the main beaches and choose isolated areas to lay their
eggs. During this period of time the breeding areas are roped off to provide
a protected area for the birds. The birds lay their eggs directly on the
ground and are not easily seen due to their coloring, which closely matches
the surroundings.
Missy
Christie, an Environment Specialist with the Charlotte County Government,
briefs a group of volunteers known as the Shorebird Stewards at Stump
Pass. The volunteers monitor the area for nesting birds, using binoculars
and a scope, and educate the public regarding the habitat of the birds
and the impact of humans and animals on their survival.

When nesting birds are disturbed and flushed from their nest, the eggs
are exposed to temperature extremes, predators like crows, raccoons and
dogs, and risk being stepped on by humans. In some cases the birds will
abandon the nest with the eggs with fatal results for the chicks.
What can you do to help:
Please stay out of the roped off areas.
Keep your dogs off the beach and most importantly away from posted nesting
areas. Birds see dogs well over over 300 ft away and will take flight
to protect their eggs or young.
If birds take flight, you are too close.
Stop and chat with the Shorebird Stewards, the possibility is there that
they have a nest in view on the scope.
Consider volunteering for the Shorebird Stewards. Contact Missy at 941-681-3746
if you are interested.
Sea Turtles:
Florida is an important place for the endangered and threatened
sea turtles of the world.
There are five species of sea turtles that inhabit the Gulf of Mexico.
Three species are endangered, Kemp's Ridley, Leatherback and Green, and
two are threatened, Loggerhead and Hawksbill.
The decline in the population of the sea turtle include the loss of nesting
and feeding sites due to coastal development, intentional hunting, pollution,
cold weather and accidental capture in fishing gear. These creatures are
well adapted to their ocean environment but they need air to survive.
When caught in a trawler net the animal will drown. A
"Turtle Excluding Device", commonly referred to as a TED,
allows all bycatch above 4 inches to be stopped by the TED and allowed
to escape.
During
the summer months, there are approximately 50,000 sea turtles in Florida.
This makes the state the most important nesting area in the United States.
Depending on the source of the data, the maturing age of the sea turtle
is somewhere between 10 - 40 years of age. The female turtle comes ashore
at night to lay her eggs starting in May and continues into September.
It takes the nesting female 1 - 3 hours to crawl out of the water, make
her nest by digging in the sand with her rear flippers, depositing about
100 rubbery eggs the size of ping pong balls in the nest and then covers
it by flipping sand over the nest before crawling back into the ocean.
Nesting sea turtles are very timid and vulnerable and may be easily frightened
away, return to the water and drop their eggs, if they are disturbed.
Each day volunteers search the beach area during the nesting period to
locate fresh nests and mark the
area with tape to protect the nest. In some areas, a cage is erected over
the nest to protect the nest from animal scavengers, such as raccoons
etc. Incubation
of the eggs takes between 45 - 75 days. As the hatchlings emerge from
the eggs and thrash around, the sides of the nest collapse pushing the
hatchings out. The hatchlings, about 2 - 4 inches in length depending
on the species, must now race for the water (often 100 to 200 feet away)
towards the brightest light, which should be the moonlight reflecting
off the water. Artificial light from houses and buildings attracts hatchlings
away from the ocean, the first of their obstacles to survival. Ghost crabs
will pull a hatching into it's burrow for an easy meal, and upon reaching
the water hatchling make a bite size meal for fish, birds and a host of
predators in the ocean. It is estimated that the chances of a sea turtle
reaching the age of maturity is 1:1000.
The Loggerhead turtle is the most common sea turtle in the state of Florida.
It is listed as a threatened, not endangered species. Named for it's large
head it has very powerful jaws used to crush clams and crabs on which
it feeds. The female Loggerhead turtle returns to the same beach, where
they were hatched, to lay her own eggs.
Loggerhead turtles can survive for 70 years or more.
The Green sea turtle is the second most common turtle in Florida. The
Green sea turtle is the only plant eating sea turtle.
The Leatherback turtle is the largest of all species that live in the
water. Fully grown, these turtles can weigh as much as 2,000 pounds and
grow to 8 feet long. The biggest difference from other turtles is that
it doesn't feature a hard shell. It does have layers of oily skin there
instead. They tend to live in both waters that are cold and those that
are warm so they are quite adaptable. Their main source of food comes
from jellyfish. However, their bodies have a hard time digesting them
so many of them die due to an intestinal blockage. They also consume other
items in the water that resemble jellyfish including plastic bags (pollutant
that will block their digestive system).
The Kemp's Ridley sea turtle is one of the smallest in the world. They
weigh only about 100 pounds and they are from 2 ½ feet long to
3 feet long. They are gray and green in color with some yellow underneath
their shell. Their diet includes jellyfish, mollusks, and a variety of
small fish.
The Hawkbill sea turtle features a heart shaped shell on its body. As
the turtle gets older that heart shape will change and the shell will
get longer. The head is small and tapered with a mouth that resembles
the beak of a bird. The main source of food for the Hawkbill sea turtle
is sponges. They are very particular about the types that they consume
too. They also consume jellyfish, fish, mollusks, crustaceans, and worms
to satisfy their need for food.
WHAT YOU CAN DO TO HELP:
All species of sea turtles fall under the Endangered Species Act and
are protected by law.
Do NOT disturb a sea turtle nest. If you see a nesting sea turtle, give
her ample room, do not disturb (no flash pictures) and allow her to crawl
back into the water when she has completed her task.
If you are visiting or live near the beach you can help by keeping outside
lights off during nesting season (May - October).
Make sure you remove chairs, toys, umbrellas and other gear from the beach
at night.
Level all sand castles and fill in any holes created, which cause hatchlings
problems enroute to the Gulf.
Pick up all trash. Sea turtles mistakenly eat plastic, resulting in eventual
death.
