Sooty Grouse

Sooty Grouse

Sooty Grouse

When I first saw this bird it was known as a blue grouse. In 2006 DNA evidence showed that two separate species comprised what was then called a blue grouse. The American Ornithologist’s Union separated Dendragapus obscurus (blue grouse) into sooty grouse (D. fuliginosus) and dusky grouse (D. obscurus). Dusky grouse are more of an inland species found in the Rockies while sooty grouse extend from Southeastern Alaska to Northern California between the coast as the Western Rockies. The sooty grouse is darker than the dusky grouse and there are differences in their calls.

A large grouse, the sooty grouse male is grey overall. He has white-based feathers on either side of the neck covering an inflatable sac  and yellow eye combs. During display the yellow neck sac is visible, surrounded by the white feathers and the eye combs become orange or red. Females are a more mottled brown. Juveniles resemble the females. The sooty grouse is separated from other grouse species by a broad grey terminal band on the tail. (In a poor picture I took of this bird flying, the grey band is visible.)

The sooty grouse is non-migratory. During the breeding season they inhabit openings in and the edges of conifer forests that have an understory of grasses and shrubs. During the winter the sooty grouse moves into dense conifer stands, usually at a higher elevation than their breeding grounds.

In the winter sooty grouse sit in conifer trees and eat mostly conifer needles. At other times of the year they forage on the ground eating leaves, flowers, buds, berries and some insects in addition to conifer needles. Young sooty grouse eat more insects than the adults and eventually become primarily vegetarian as adults.

In some areas of their range sooty grouse are declining in numbers, particularly in the south of their range. (As upland game birds there are hunting seasons for sooty grouse.) Leonard and I do not see sooty grouse often – not for lack of effort. This sooty grouse was at about 7,000′ elevation in the Medicine Lake Highlands of Northern California. Sooty grouse are usually found singly, the exception being a hen with her young. This grouse was one of a pair – both similar looking. My first thought was that the pictured bird was a female. But it might be a juvenile since juvenile sooty grouse are similar to females.

No matter, female or juvenile, Leonard and I were excited to see a sooty grouse.

Another cynipid wasp that induces a fascinating gall on blue oaks and Oregon white oaks (Quercus garryana) is the sunburst gall wasp (Andricus stellaris). As with the ball-tipped gall wasp, another cynipid wasp featured in my last post (see “Ball-tipped … Continue reading

Ball-tipped Gall Wasp

This gallery contains 4 photos.

Most wildflowers have long faded and due to the continuing drought in our area (Northern California) fungi are scarce while the birds are unpredictable and scattered. Thus while wandering about I find myself focusing on usually overlooked subjects. Oaks support … Continue reading

Depending on their location, intertidal marsh plants must tolerate varying amounts of submergence in brackish tidal water and varying degrees of salinity. Some plants thrive in a broad range of marsh conditions while others only survive within narrow environmental parameters. … Continue reading

Yellow-rumped Warbler

This gallery contains 4 photos.

Dendroica coronata, yellow-rumped warbler, consists of six (or more) subspecies divided into two main groups –  the Myrtles, generally more Eastern, and the Audubons, a bird of the Mountain West. These two groups were considered full species until 1973. Yellow-rumped … Continue reading
