Semper's Warbler Leucopeza semperi

Small songbird endemic to the island nation of St. Lucia, which is located in the Caribbean about 400 miles southeast of Puerto Rico. It may now be extinct. While there have been a few reports in recent decades, the last substantiated sighting was in 1961. It is a dull, mostly gray bird with slightly paler underparts, brownish wings, yellow legs, and a hint of a pale eyebrow. Inhabits rainforest understory, and historical accounts suggest that it is quite shy and largely terrestrial. Its decline has been mainly attributed to introduced predators, though other factors may have been involved as well.
