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.
As of January 9th 2025 according to the iGoTerra website, there are 18 birders who have added 9,000 or more species of birds to their life lists. An additional 15 birders have added at least 8,000 species of life birds. Note: all known sources of bird species life list data are self-reported. Birders with over 8,000 species include:
Juveniles become capable of sustained flight two weeks after fledging. Chicks become sexually mature at one year of age. Bird banders have found that only 25% of young robins survive their first year. The longest known lifespan of an American robin in the wild is 14 years; the average lifespan is about two years. [16]
Although their typical lifespan is considerably shorter, common ravens can live more than 23 years in the wild. Young birds may travel in flocks but later mate for life , with each mated pair defending a territory .
This is a list of maximum recorded animal lifespans in captivity. Only animals from the classes of the Chordata phylum are included. [1] On average, captive animals (especially mammals) live longer than wild animals.
The average lifespan of a ruby-throated hummingbird is estimated to be 3–5 years, with most deaths occurring in yearlings, [23] although one banded ruby-throated hummingbird lived for 9 years and 2 months. [24] Bee hummingbirds live 7–10 years. [16]
The 100 species with longest life-spans recorded and verified [1] This is a list of the longest-living biological organisms: the individual(s) (or in some instances, clones) of a species with the longest natural maximum life spans. For a given species, such a designation may include:
Penguins Ostriches. This article lists living orders and families of birds.In total there are about 11,000 species of birds described as of 2024, [1] though one estimate of the real number places it at almost 20,000. [2]
