Field Marks and
Identifying Characteristics:
I initially found 1 here on 1/7/24, but it was late, windy and cold so I did not attempt photos (Note at that time TBLO was not a review species). I returned on 1/16 to relocate, photograph and see what else may be mixed in. I arrived at around 1:30pm, initially I found a couple small flocks that only had Horned Larks, but eventually found a bigger flock farther out and almost immediately located a Thick-billed Longspur in the scope. While watching and studying it, I noted another. Notes from sighting-first saw tail in flight, white with dark T(white-tailed Longspur would have been a better name)noted big head and stout bill, short tailed with chunky body, black breast shield and gray belly. Noted 2 together several times, at one point found a group separate from Larks with 5 or 6 TBLO and 2 or 3 LALO
(see photos)
Song or call & method of delivery: Heard Longspur rattle flight calls several times, but Lapland also present so unsure which species
Behavior: Feeding on weeds and pickleweed sticking up through 6inches of snow, then flocks would flush, fly around then re-land, over and over
Habitat: Pickleweed-saltgrass playa near wetlands along east shore of Great Salt Lake
Similar species and how
were they eliminated:
Lapland Longspur- direct comparison, smaller head and bill, rich rufous tones with bold black streaking on flanks and dark auriculars, black upper breast with white belly, only 1 white outer tail feather

Chestnut-sided Longspur-smaller head and bill, with wing bars and a blackish belly. 3 white outer tail feathers

Smith's Longspur-smaller head and bill, buffy belly with black streaking and auriculars

Snow Bunting-whiter overall with white wing patches, black primaries.

No other Longspur or passerine has the same distinctive white tail with a dark T
Previous experience with
this & similar species:
Yes, several
