White-fronted Swift Cypseloides storeri

Sections

Described only in the early 1990s, the White-fronted Swift is endemic to a small area of southwest Mexico, where it is known solely from several highland localities in the states of Guerrero, Michoacán, and Jalisco, based on a handful of specimens and a few sight records, the most being in 1995 and, perhaps, in 2002. Difficulties in separating this species from the undoubtedly very similar Chestnut-collared Swift (Cypseloides rutila) have clouded efforts to understand the White-fronted Swift’s status and distribution. The White-fronted Swift is separated from other swifts only by virtue of its strikingly uniform plumage, proportionately shorter, square-ended tail, broad-winged, chunky-bodied, and relatively large-headed appearance. Some authors have speculated that the species is perhaps a migrant and is only present in southwest Mexico during May to September, but more data are required to confirm or deny this hypothesis. It probably nests in close proximity to waterfalls, like other Cypseloides swifts, but again this demands confirmation.
