Field Marks and Identifying Characteristics: |
Tail feathers of the displaying male included broad pale banding,
causing the tail to appear more pale than the tail feathers of Greater
Sage-Grouse. The black filoplumes were very prominent as the male
displayed, sometimes standing straight up as can be seen in attached
photos. The relatively soft display vocalizations or acoustical
components made by the males matched the Sibley recording. (see photos) |
Song or call & method of delivery: |
Swishing and water drop sounds heard as the male displayed for a female. |
Behavior: | Displaying as shown in photos |
Habitat: | Tall grass and scattered sagebrush |
Similar
species and
how were they eliminated: |
Greater Sage Grouse is similar, but the prominent black filoplumes, broad pale banding in the tail, and softer vocalizations were noticeably different from Greater. |
