The western meadowlark is the state bird of Wyoming. This list of birds of Wyoming includes species documented in the U.S. state of Wyoming by the Wyoming Game and Fish Department (WGFD) as of May 2021 with some additions from Avibase. [1] The list contains 452 species.
Finches are seed-eating passerine birds, that are small to moderately large and have a strong beak, usually conical and in some species very large. All have twelve tail feathers and nine primaries. These birds have a bouncing flight with alternating bouts of flapping and gliding on closed wings, and most sing well.
The northern cardinal, which represents seven states, is the only bird to hold the status of state bird in more states. [ 12 ] During the 2017 regular session of the Oregon Legislature, there was a short-lived controversy over the western meadowlark's status as state bird versus the osprey .
Colonies of over a million birds have been recorded, both in the tropics (such as Kiritimati in the Pacific) and in the polar latitudes (as in Antarctica). Seabird colonies occur exclusively for the purpose of breeding; non-breeding birds will only collect together outside the breeding season in areas where prey species are densely aggregated. [50]
The osprey (/ ˈ ɒ s p r i,-p r eɪ /; [2] Pandion haliaetus), historically known as sea hawk, river hawk, and fish hawk, is a diurnal, fish-eating bird of prey with a cosmopolitan range. It is a large raptor, reaching more than 60 cm (24 in) in length and 180 cm (71 in) across the wings. It is brown on the upperparts and predominantly greyish ...
It often will imitate the calls from birds of prey such as the red-tailed hawk, red-shouldered hawk, and osprey as a warning of danger to others or territorial behavior, causing other birds to seek cover and flee feeding areas. [11] [13] Steller's jays have the ability to assess risk using different predator detection cues.
Originally called the "sea pie", it was renamed in 1731 when naturalist Mark Catesby claimed that he had observed the bird eating oysters. [2] The current population of American oystercatchers is estimated to be 43,000. [2] There are estimated to be 1,500 breeding pairs along the Atlantic and Gulf Coasts of the US. [3]
The area of Wyoming now characterized by the Bighorn Mountains was a marine environment during the Ordovician. Ostracoderms swam in this sea. [4] During the Silurian, the sea withdrew from Wyoming and local sediments were eroded away. During the Devonian, the sea returned to the state and remained until the Permian when it started to withdraw ...
