Field Marks and Identifying Characteristics: |
Sparrow-sized, sparrow-looking---brownish striped---bird with a fairly short (i.e., compared to most other sparrow-sized, brownish birds the observer knows) notched tail. Tail was whitish on dorsal surface with a dark triangle pattern which alerted the observer (see drawing). There were no other distinct markings. |
| Song or call & method of delivery: | Calls were somewhat musical, but seemed to be "weak" as if the bird was out of breath. Sounded finchlike, short note duration sung continuously as bird flew, like something between a house finch and a goldfinch vocally. |
| Behavior: | In terms of behavior, the bird did not pump its tail as it flew. It flushed vertically to about 8 m then attempted to fly S; caught by strong gusts of wind from SW; flew in a circle overhead then went NE. It did not land within sight of the observer. Bird was heard almost immediately as it was flushed. |
| Habitat: | "ringed with Gambel's oak and other woody species" |
| Similar
species and
how were they eliminated: |
Longspur-like bird did not fit markings or behavior of pipit, horned lark, warber, junco, or vesper sparrow. |
| Previous
experience with this & similar species: |
Avocational bird fieldwork experience of observer: 4 years in the forests and river bottoms east of the Mississippi; 12 years in Rocky Mts., western deserts, and coast from San Diego to Seattle. |

| Additional comments: |
Circumstances: Observer was hiking and migrant -bird surveying along an
old jeep trail on the south side of the meadow. Bird flushed from ground
when observer was about 6 m away. Other Birds in Area: Longspur-like bird was alone when it flushed (i.e., no other birds flushed with it). Robins, magpies, black-capped chickadees, flickers, and small, brownish sparrow-sized birds were seen flying either singly or in groups or were foraging in groups especially in the oaks on the perimeter. Juncoes and white-crowned sparrows were heard, as were many of the other birds. |
