National Geographic, with Alderfer, Paul Hess, and Noah Strycker, also published National Geographic Backyard Guide to the Birds of North America in 2011. A second edition was released in 2019. Like the pocket guide, this guide is 256 pages and outlines the 150 most common yard birds in North America.
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.
The sharp-shinned hawk (Accipiter striatus) or northern sharp-shinned hawk, commonly known as a sharpie, [2] is a small hawk, with males being the smallest hawks in the United States and Canada, but with the species averaging larger than some Neotropical species, such as the tiny hawk.
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.
Nighthawks prefer to nest in edge and early successional habitats, making them one of only a handful of birds which will live and hunt in burned or clearcut patches of forest. [15] The common nighthawk is drawn into urban built-up areas by insects. [5] The common nighthawk is the only nighthawk occurring over the majority of northern North America.
While all hawks symbolize keen sight and rising above challenges, different hawk species each carry their own meaning: Red-Tailed Hawk. Extremely common in North America, the red-tailed hawk is ...
Unlike some birds, but similar to other diurnal raptors, most hawk species are violet-sensitive but cannot perceive ultraviolet light. [11] Hawks also have relatively high visual acuity – the distance at which they can resolve an image – with red-tailed hawks reported to have 16.8 cycles per degree. [12]
With a massive distributional gap consisting of most of South America, the rufous-tailed hawk is considered a separate species now, but the two hawks still form a "species pair" or superspecies, as they are clearly closely related. The rufous-tailed hawk, while comparatively little studied, is very similar to the red-tailed hawk, being about ...
