I took this photo of a Prothonotary Warbler at the Sherburne Wildlife Management Area near the Whiskey Bay exit in the Atchafalaya Basin. Louisiana Wildlife and Fisheries ornithologists were netting and banding birds in their ongoing studies of songbirds in the area. Each bird was weighed, measured, checked for molting and sex determination, and then banded. All data is sent to a central processing information center in Maryland. It was a fascinating experience for me to witness this and to get a rare opportunity to take photos of these birds with, of all things, a macro lens.
Prothonotary warblers are named after Roman Catholic notaries who wear yellow vestments.
The songbird is a cavity nester which makes use of holes bored in trees by woodpeckers. They live in wooded swamps and surprisingly, if a fledgling falls into the water, it can swim to safety.These warblers make their summer homes throughout the eastern part of the United States.
