Also known as Latimer’s Vireo, Puerto Rican Vireo is most commonly found throughout the western and central areas of this Greater Antillean island. It is a rather dull-looking vireo, lacking any wing bars, although it has a slight whitish stripe above the lores. Like most vireos, this species is perhaps most likely to be initially located by virtue of its distinctive, three- to four-syllable song, which can be heard in various forest types, from dry coastal scrub to wet montane areas. It is sometimes even found in mangroves. Puerto Rican Vireo is not considered to be globally threatened, but is vulnerable to predation by introduced mammals such as rats and feral cats, and its nests are frequently parasitized by Shiny Cowbirds (Molothrus bonariensis), which is a relatively recent arrival on the island.
