Interesting Facts

 The Dusky Grouse and the Sooty Grouse were considered to be the same species, the Blue Grouse, until the American Ornithologists’ Union split them in 2006 based on DNA evidence.

 When flushed, these birds will often fly to an evergreen bough and just freeze at which time one may be able to walk to within a few feet of the bird.

 They have large numbers of eggs in their clutches, as many as fifteen have been observed. Even though hatching success may be as high as 90%, mortality of the young can reach as much as 50% prior to the fall hunting season. This is often due to inclement weather after the hatch as well as a poor food supply or predators.

 A group of grouse has many collective nouns, including a "chorus", "covey", "drumming", "grumbling", and "leash" of grouse.

Dusky Grouse

Dusky Grouse: Large, chicken-like bird, dark gray to blue-gray plumage, red-orange eye combs, black squared tail with narrow pale gray terminal band. Patch of violet-red skin on neck surrounded by white feathers is displayed during courtship. Formerly (with Sooty Grouse) known as Blue Grouse.

● Song: "hoot-hoot-hoot-hoot", "whoop-whoop-whoop"

● Foraging & Feeding: Dusky Grouse: Feeds almost exclusively on conifer needles during winter. In spring, summer, and fall, diet shifts to insects, spiders, salal berries, snowberries, red huckleberry fruit, and fern tips; forages on the ground.

● Breeding & nesting: Dusky Grouse: Seven to sixteen pink buff eggs, usually spotted brown, are laid in a ground scrape lined with pine needles and grass, usually sheltered by a stump or rock. Incubation ranges from 25 to 26 days and is carried out by the female. Precocial young leave nest soon after hatching.

● Similar species: Dusky Grouse: Male Spruce Grouse has white bars on breast, barred back, and brown terminal tail band. Female has narrow rust-brown terminal tail band and white bars on underparts. Ruffed Grouse is browner, has black subterminal tail band and more white on underparts. Sooty Grouse has a wider gray terminal band on tail, male has yellow air sacs and yellow combs over eyes.

Flight Pattern

Strong, direct, alternates rapid wing beats with glides.

4 and 6 letter alpha codesX

The four letter common name alpha code is is derived from the first two letters of the common first name and the first two letters of common last name. The six letter species name alpha code is derived from the first three letters of the scientific name (genus) and the first three letters of the scientific name (species). See (1) below for the rules used to create the codes..

Four-letter (for English common names) and six-letter (for scientific names) species alpha codes were developed by Pyle and DeSante (2003, North American Bird-Bander 28:64-79) to reflect A.O.U. taxonomy and nomenclature (A.O.U. 1998) as modified by Supplements 42 (Auk 117:847-858, 2000) and 43 (Auk 119:897-906, 2002). The list has been updated by Pyle and DeSante to reflect changes reported by the A.O.U from 2003 through 2006.

ITIS CodesX

The Integrated Taxonomic Information System (ITIS) was established in the mid-1990�s as a cooperative project among several federal agencies to improve and expand upon taxonomic data (known as the NODC Taxonomic Code) maintained by the National Oceanographic Data Center (NODC), National Oceanic and Atmospheric Administration (NOAA).

To find the ITIS page for a bird species go to the ITIS web site advanced search and report page at http://www.itis.gov/advanced_search.html. You can enter the TSN or the common name of the bird. It will return the ITIS page for that bird. Another way to obtain the ITIS page is to use the Google search engine. Enter the string ITIS followed by the taxonomic ID, for example "ITIS 178041" will return the page for the Allen's Hummingbird.
