Yellow-rumped warblers are very common in the winter along the Florida Gulf Coast, but not always easy to photograph. They love to forage in flocks. They flit and flutter at a frenetic pace in and around the brush and brambles at places like Fort Pickens, part of the Gulf Island National Seashore. They land for rarely more than a second before they flight off into the brush where it is near impossible to get them in focus before they move on.
