Media notes
PROBABLY VERMIVORA "LEUCOBRONCHIALIS" [= "Brewster's" Warbler]. MOSTLY VERMIVORA PINUS CHARACTERS. FIRST HEARD GIVING V. PINUS LIKE SONGS. BNA: Twenty-four "Type I" songs, almost all of which are typical of V. chrysoptera song with four notes ("zeee bee bee bee"). Some songs have only three notes ("zeee bee bee" - 0:06, 1:20, 3:02, 3:40) and three songs are intermediate between those of V. chrysoptera and V. pinus (contrary to BNA - 0:39, 0:58, and 4:11). The "chip" notes heard in the middle part of this recording (2:07-2:24) may also have been given by this bird.
