I was parked in an area looking for a Cinnamon Raccoon that I had photographed earlier when this Prothonotary Warbler flew next to my vehicle. I was at the Sequoyah National Wildlife Refuge where I do see these birds often. They like staying in the dense, woody areas near water which makes it difficult to photograph them.
The Prothonotary Warbler forages actively in low foliage, mainly for insects and snails. It is the only eastern warbler that nests in natural or artificial cavities, sometimes using old downy woodpecker holes. The male often builds several incomplete, unused nests in his territory; the female builds the real nest. It lays 3–7 eggs. (Source: Wikipedia)
