Florida Scrub-jay

Florida Scrub-jay
The Florida Scrub-jay is a rather unique bird. This member of the Corvidae family is found only in central Florida. It is the only bird that is endemic to Florida and one of only 15 bird species that are endemic to the U.S. At one time they were considered the same species as the western scrub-jay but scientific study showed that they were genetically different enough to be identified as a separate species. They live, as family groups, in Florida scrub habitat. Unfortunately as this type of habitat has given way to development their numbers have dwindled. In 1975 it was listed as a threatened species in Florida and in the 1990's it was estimated that their were only 4000 pairs left in the wild. Because they are a member of the Corvidae family they are fairly intelligent. I photographed this bird at Merritt Island National Wildlife Refuge.

Double-crested Cormorant

Double-crested Cormorant
Double-crested cormorants are found through out much of North America. They are usually found in fresh or salt water habitats where they hunt fish by diving under the water. They are great swimmers, partially because they do not produce preening oils like most other waterfowl. These oils help birds like geese and ducks keep their feathers waterproof. With out these oils the cormorants feathers can get wet, which makes them less buoyant. Having less buoyancy helps them swim better underwater than many other species of waterfowl. Unfortunately it means that they have to dry themselves off by holding their wings out in the sun in order to make themselves light enough to fly. In most places that I have traveled cormorants are quite skittish but things are quite different in south Florida. It was not uncommon to see cormorants perched on the boardwalk rails at locations like Green Cay Nature Center.
