Red-eyed Vireo

The Red-eyed Vireo, Vireo olivaceus, is a small American songbird, 13-14 cm in length. It is somewhat warbler-like but not closely related to the New World warblers. Adults are mainly olive-green on the upperparts with white underparts; they have a red iris and a grey crown edged with black. There is a dark blackish line through the eyes and a wide white stripe just above that line. They have thick blue-grey legs and a stout bill. They are yellowish on the flanks and under their tail. This bird, not always seen, may sing for long periods of time; it appears to be endlessly repeating the same question and answer. It holds the record for most songs given in a single day among bird species
