Field Marks and
Looked like a very typical meadowlark (either species, in shape and overall
plumage and color). The bird appeared to have a very dark eye line and crown
stripes, along with a white malars and
pale brown auriculars. This made for a very striking head pattern with the white malar being quite noticeable.
Another unique feature was the streaking on flanks. The bird had long streaks from the shoulders to the undertail coverts on the sides.
The bird flew shortly after the initial observation and headed passed me to another field. Although I didn't have a great look at the tail, it appeared to show a lot of white across the entire tail, as ooposed to just the white edges of a Western.
|Song or call & method of delivery:||none heard which is why I am assuming the bird was a female.|
|Behavior:||Sat on a sprinkler post looking around for about 45 seconds before taking flight, and dropping into the grass in a field about 250 feet its initial location|
|Habitat:||One green agricultural field and one dry/dead agricultural field in an otherwise dry desert.|
were they eliminated:
Western Meadowlark. Despite the bird not vocalizing, the distinct field marks I
believe clearly eliminate Western. The rather crisp, and bold head pattern
highlighted by a pale, white, malar, and very dark eye line and crown stripes
point towards Eastern.
The streaking on the side is another good sign for Eastern, as Westenr are typically spotted or show short streaks and spots.
Finally the large amount of white flashed in the tail during flight would seem to point to Eastern as well.
Also of note was the rather quick departure from the perch it was using. Eastern Meadowlark tend to have a very abrupt and fast departure from the perched position, where Western may seem to have a slower and more relaxed departure.
this & similar species:
|Have seen 1,000's of Western Meadowlarks from Oregon to Wisconsin, and numerous Eastern in Wisconsin, Iowa, Illinois and Indiana.|
