Pine warblers are permanent residents that can always be found in the pinewoods and surrounding hammock habitats you pass through as you drive into the refuge. Listen for their high, trilling song from early spring to mid-summer from up in the treetops of the pinewood habitats. Prairie warblers are a fairly common transient species during migration, and a few may be seen throghout the winter. They can also be found in a variety of habitats, from within the hammocks to brushy thickets along the dikes. The dark semi-circle under the eye and the bright yellow streaked underparts are good field marks.
Single birds are sometimes present in mixed species feeding flocks of the hammock habitats.
The black, yellow and white patterning of the head and throat are distinctive if you see them well. This can be difficult, as they tend to forage high in the canopy. The common yellowthroat is an abundant permanent resident, but unlike the similar sounding yellow-throated warbler, is more often found low in the vegetation at woodland edges, marsh thickets, or in the marsh itself. Listen for the wichery wichery wichery song of the males from late winter through spring. American redstarts are transient migrants, but are sometimes numerous, especially in the fall.
