Wilson’s Warbler male 5/8/18

While yesterday’s Prairie Warbler was at the northern limit of its breeding range, the Wilson’s Warbler is at the southern limit, or more likely just passing through on its way to the Canadian boreal forest. This is more of an open forest bird, often found foraging near the ground or in the understory, especially in wetter areas. Again yellow below and olive-green above, the males have the unmistakeable black cap to go with their deep black eyes. Averaging between 4 and 4.5 inches, they are one of the smallest of the wood warblers.
