    Formal Taxonomy
    Animalia - Craniata - Aves - Passeriformes - Parulidae - Geothlypis - Exhibits relatively deep mtDNA separations between populations in Washington and those in the central and eastern states (Ball and Avise 1992). Populations around Lake Chapala, Jalisco, regarded as a distinct group, CHAPALENSIS (AOU 1998). Sometimes regarded as conspecific with G. ROSTRATA, G. FLAVOVELATA, and G. BELDINGI (AOU 1983). Further study required of species relationships with GEOTHLYPIS (AOU 1998).

    Upperparts olive-brown; throat and breast yellow; sides tan; belly whitish; adult male has a broad black mask, bordered above by white; immature male has a pale eye ring and an indistinct mask; 11-14 cm long (NGS 1983).

    Migration
    true - true - true - Winter: withdraws from areas north of the southern U.S. Arrives in Puerto Rico by September-October, departs mostly by the end of April but some remain into June; appears to congregate and pair before migrating north in spring (Raffaele 1983). Migration in Costa Rica extends from mid-October to November and from April to early May (Stiles and Skutch 1989). Present in South America mostly October-April (Ridgely and Tudor 1989).

    Food Comments
    Eats various small invertebrates obtained among low plants.
    Reproduction Comments
    Clutch size is 3-6 (usually 4). Usually produces two broods per year. Incubation, by female, lasts 11-13 days. Young are tended by both parents, leave nest at 8-10 days. Polygyny has been observed.
    Ecology Comments
    Density was about 1.5-2.5 territories per ha in southeastern Massachusetts (Morimoto and Wasserman 1991).
