Geothlypis tolmiei
male
MacGillivray’s Warbler is the western, montane counterpart of Mourning Warbler. The sexes are dissimilar. Adult males have an olive-buff back, wings, and tail. There is a blue-gray hood, darkest on the lower margin and lores, and there is a broken white eyering. The underparts are otherwise bright yellow. Adult females are similar to an adult male but less colorful and with a pale gray hood. Immatures are similar to an adult female but with a mainly buffish-brown hood and a pale throat. The legs are pink in all birds.
MacGillivray’s Warbler is present as a breeding species mainly from June to August. It spends the rest of the year in Central America. This secretive wood warbler favors dense thickets and undergrowth, making it a challenge to see.
