- FAMILY PHAETHONTIDAE - TROPICBIRDS
The order of Swifts and Hummingbirds. As of 2024, 46 species of Apodiformes have been observed in iNaturalist in the US and 477 throughout the world.
In the family of Swifts, Apodidae, 8 species have been observed in iNaturalist in the US and 108 throughout the world.
In the family of Hummingbirds, Trochilidae, 38 species have been observed in iNaturalist in the US and 369 throughout the world.
Swifts can be found throughout the lower 48 of the U.S. but not in any zoos. The most commonly observed species in iNaturalist is the Chimney Swift (Chaetura pelagica), which ranges east of the Rocky Mountains. The second-most observed species is the White-Throated Swift (Aeronautes saxatalis), which ranges in the western U.S., almost exactly where the Chimney Swift does not. Vaux's Swift (Chaetura vauxi) and the Black Swift (Cypseloides niger) are also commonly observed and are found in the West.
Between Joshua Tree and Yosemite, in Trip 7, all three of the commonly observed western swifts can be experienced. The Chimney Swift is common at Cheyenne Bottoms in the Fall.
