In this list of birds by common name 11,278 extant and recently extinct (since 1500) bird species are recognised. [1] Species marked with a "†" are extinct.
In total there are about 10,000 species of birds described worldwide, though one estimate of the real number places it at almost twice that. [1] The order passerines (perching birds) alone accounts for well over 5,000 species. Taxonomy is very fluid in the age of DNA analysis, so comments are made where appropriate, and all numbers are approximate.
These small but chunky birds are characterized by their round body, long tails, and warm orange undersides. When they’re not eating insects and spiders, they’re singing bird songs.
Hummingbirds are small birds capable of hovering in mid-air due to the rapid flapping of their wings. They are the only birds that can fly backwards. Unless otherwise noted, all species listed below are considered to occur regularly in North America as permanent residents, summer or winter residents or visitors, or migrants.
For species found in the 50 states, Puerto Rico, and the U.S. Virgin Islands, the taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) used in the list are those of the AOS, the recognized scientific authority on the taxonomy and nomenclature of North and Middle American birds.
Many species of the second major avialan lineage to diversify, the Euornithes (meaning "true birds", because they include the ancestors of modern birds), were semi-aquatic and specialised in eating fish and other small aquatic organisms.
The taxonomic treatment [3] (designation and sequence of orders, families and species) and nomenclature (common and scientific names) used in the accompanying bird lists adheres to the conventions of the AOS's (2019) Check-list of North American Birds, the recognized scientific authority on the taxonomy and nomenclature of North America birds.
In 61 species, birds’ wings grew longer on average. Nearly a third of the 77 species showed clear trends toward longer wings. The research was made possible by extensive, detailed data captured ...
