(01/08/1999) -- In the Merritt Island National Wildlife Refuge, which shares a boundary with the space center, an anhinga gets ready to eat the fish it captured in the nearby Indian River with its long, dagger-shaped bill. The bird will flip its catch into the air and gulp it down headfirst. The anhinga is also known as the 'snakebird' because in the water its body is submerged so that only its head and long, slender neck are visible. Ranging the Atlantic and Gulf Coasts from North Carolina to Texas, north in the Mississippi Valley to Arkansas and Tennessee, and in the South to South America, it inhabits freshwater ponds and swamps with thick vegetation. They are often seen with wings half-open, drying them in the sun since they lack oil glands with which to preen
