Orange-crowned WarblerOreothlypis celata
One of the plainest of warblers, the orange feathers on its head almost never visible, this species is also among the most hardy. In winter, when most warblers are deep in the tropics, Orange-crowns are common in the southern states. They are usually seen singly, sometimes loosely associated with flocks of other birds. At all seasons they tend to stay fairly low, in bushes or small trees, flicking their tails frequently as they search among the foliage for insects.
