Field Marks and
Identifying Characteristics:
beautiful nonbreeding male that was closing in on breeding plumage. light gray, tan base color, with a dark to black chest and undersides, but not quite as fully black as a breeding male. Streaked brown back, bright rusty chestnut collar coming in, with a dark "ear spot", and a blonde supercillium and "Mustache".
(see photos)
Song or call & method of delivery: Frequent Squeaky rattle calls, that could be described as Squirrely.
Behavior: Mostly stuck to the road to feed. the snow from the night before, had forced everything to the road. this longspur was seemingly tied to the road, even when HOLA's would get up and flock around, the longspur would stay down and continue feeding. we were able to observe this bird frequently through the day, for large chunks of time.
Habitat: grassy AG fields in Howell. snowy conditions.
Similar species and how
were they eliminated:
Lapland longspur; we were able to rule out LALO due to the presence of black in the chest and underparts, plus the bright chestnut collar cements this bird as a CCLO.
Thick-Billed Longspur; We were able to rule out TBLO due to the extensive black in the chest and underparts, where a TBLO would only have a Smaller black V band in the chest. the chestnut collar rules out TBLO, as well as the lack of a large pink bill.
Previous experience with
this & similar species:
this was my second sighting of CCLO, the first being a female. I had previous experience with the more common LALO.
