Kestrels are in the small group of raptors where males and females can be distinguished by their coloration. Like most other raptors the female kestrel is larger then her male counterpart but her coloration is much more muted and earthy. This is a defense mechanism for when the female is on the nest incubating her eggs. since it is smaller then many other raptors the kestrel is often on the other side of the predator/prey relationship. Her brown striped pattern is camouflage that helps her blend in with the sticks around her nest. The male does not help with incubating the eggs and so it is not necessarily for him to be as inconspicuous. As you can see from the top photo the males are much more brightly colored.

Kestrel
The kestrel is a small raptor in the falcon family. There are different species of kestrels found around the world. They include the common kestrel in Eurasia, Nankeen kestrel in Australia, grey kestrels in Africa, the American kestrel in the Americas, as well as several other species. Like other falcons the kestrel is designed for quick flight and maneuverability. Kestrels will eat small birds, like other falcons, but will also eat small rodents and large insects. They often hunt by hovering in place over a field while they search for prey.

Pelican Island NWR
In the late 1800's Paul Kroegel, a German immigrant, was living on the banks of the Indian River Lagoon on the Atlantic Coast of Florida. His property looked out on a four acre mangrove island that was a rookery for thousands of brown pelicans and other waterfowl. Kroegel respected the wildlife and put his life on the line protecting the island, gun in hand, from hunters. In 1901 the American Ornithologist's Union and the Florida Audubon Society pushed the state of Florida to pass legislation protecting non-game birds in Florida. Kroegel was one of four men hired by the Florida Audubon as a game warden responsible for protecting the birds. After two of the other game wardens were murdered in the line of duty, naturalist Frank Chapman and William Dutcher approached president Theodore Roosevelt to try and get help from the federal government. In March of 1903 President Roosevelt signed an executive order to set aside Pelican Island as the first federal bird reservation. Kroegel was hired on as the first national wildlife refuge manager. Roosevelt went on to establish 55 bird reservations and national game preserves which eventually became the National Wildlife Refuge System.
In the 1920's the pelicans abandon Pelican Island after a hurricane tore through the island and they did not return for several years. In the 1960's the refuge was threatened by proposed land development around the island but concerned residents pushed the Florida legislature to include 422 acres of surrounding mangrove islands as a part of the refuge.In 1968 the refuge was expanded to include another 4760 acres of surrounding wetland habitat. Pelican Island itself began to shrink over time, due to erosion, and went from 5.5 acres when it was found to a little over an acre in early 2000's. In 2001 a group of organizations partnered together to expand the shoreline using oyster shells as a wavebreak. Today thousands of people visit the refuge each year. When we visited it was not peak time so we did not see the huge numbers of waterfowl that nest in the refuge. We did still manage to find a few birds to photograph as well as some spiders, dragonflies, butterflies, a tortoise and a land crab.

Darner
One of our newest education birds at The Raptor Center is this young female American kestrel. At TRC we try not to think of the birds in human terms, but since we have over 30 education birds we do name them so that we can keep them straight. Often when we get a new bird we let the community suggest names. This helps to get people more interested in raptors and The Raptor Center. Sometimes, though, the volunteers get to make the suggestions as a reward for all of the time that we donate. In the case of this female kestrel it was up to the volunteers to make the suggestions and I am very proud to say that the name that I suggested was chosen. Let me introduce you to Darner the female American kestrel. We try to name them something that we can use as a teachable moment when we are talking to people during programs or tours. American kestrel primarily eat large insects like grasshoppers, moths, butterflies and dragonflies. During migration they primarily eat common green darner dragonflies that migrate south at the same time. This is the reasoning for Darner's new name.

Least Grebe

Least Grebe |
The smallest member of the grebe family is the least grebe. They are found in a variety of wetland habitats from southern Texas, through Mexico and Central America and down into parts of South America. Like other grebes they eat a variety of aquatic prey, including small fish, tadpoles, frogs, crustaceans and aquatic insects, which they catch by diving under the water. Least grebes will sometimes nest in temporary wetlands, this helps them to avoid losing chicks to some predators such as large fish. When a predator does show up the least grebe is more likely to dive under the water to escape then they are to fly .
