Oklahoma Migratory Species Profile: Palm Warbler




This long tailed tail-pumper is a ground forager that breeds in the Boreal Forest of Canada and the northeastern US.  As breeders in the north, they will use evergreen trees and dense cover in boggy habitat.   Similar to a pipit, it can be helpful to confirm the identity with the yellow around the vent and rump as well as the white corners on the tail.  For a warbler, they are on the larger side and have a rounder belly.

Its song is a buzzy trill with a common chek call.  During fall migration, it will often be seen with kinglets, sparrows, Pine, and Yellow-rumped Warblers.  As migrants and winter birds, this songbird will be seen along forest edges, weedy fields, parks, coastal scrubland, and with scattered trees and shrubbery.  The New World Warbler is normally found in the western two thirds of the US, and is called either the Brown Palm Warbler or the Western Palm Warbler.  The Eastern Palm Warbler will be located in the eastern third of the US.

They constantly bob the tail, are on the ground more than other warblers, and are fond of berries as well as protein, sometimes being seen hawking insects if in a tree or on a shrub.  They are more at eye level or below, rather than higher canopies like many other warblers.

Palm Warblers are frequently victims of collisions with lighted towers.  It is also suspected that since the better part of these neotropical migrants breed in the Boreal Forest, they are losing population due to peat (moss) harvesting, logging, and tar sands development.

The species will use feeders if they find native plants and a good water source.
