The currently accepted scientific name for Abert's squirrel is Sciurus aberti Woodhouse, 1853. [4] Woodhouse had initially described the species as Sciurus dorsalis in 1852, but this name turned out to be preoccupied by Sciurus dorsalis Gray, 1849 (now a subspecies of variegated squirrel S. variegatoides), and thus the present species was renamed.
The Kaibab squirrel is an example of evolution occurring through geographic isolation, but not because of the canyon. [2] Compared to the Kaibab squirrel, the Abert's squirrel, with its several subspecies, has a much broader distribution and is found on the South Rim of the Grand Canyon. The difference between North Rim and South Rim Abert's ...
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. Contents
Sciurini (/ s ɪ ˈ j uː r ɪ n iː /) is a tribe that includes about forty species of squirrels, [2] mostly from the Americas. It includes five living genera—the American dwarf squirrels, Microsciurus; the Bornean Rheithrosciurus; the widespread American and Eurasian tree squirrels of the genus Sciurus, which includes some of the best known squirrel species; the Central American ...
Additionally, the paper suggests moving Andean squirrel back to subtribe Microsciurina, the dwarf squirrels, and assigns it to the newly described genus Leptosciurus. The paper's findings agree with prior assessments to synonymize Richmond's squirrel into Red-tailed squirrel and reassigns the Red-tailed squirrel into the previously monotypic ...
2. Acorn Woodpecker. These birds get their name from their unique habit of storing acorns in trees, which they use as a food source. Sometimes, they can store tens of thousands of them.
The ratites are mostly large and long-legged, flightless birds, lacking a keeled sternum. Traditionally, all the ratites were place in the order Struthioniformes . However, recent genetic analysis has found that the group is not monophyletic, as it is paraphyletic with respect to the tinamous , so the ostriches are classified as the only ...
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.
