Field Marks and Identifying Characteristics: |
I had seen several hundred Horned Larks here on Jun 20 and came out here again
specifically hoping to find Longspurs. Conditions were perfect - hundreds of
Horned Larks relatively close to the road. While scanning through the Larks I
picked out a bird that was obviously different. I admit I wasn't sure what this
one was - I was felt confident it was a longspur and was hoping it was a
McCown's but was unsure on the species. The shape of the bird was more heavy or
stocky compared to the larks. It was overall plain dull brownish but nothing
that really stood out. It was finely streaked on the crown and had a broad
eyestripe and a light patch on the face. The breast was unstreaked, but not
uniform and appeared to be slightly tinged brown. I watched this bird for about
5 minutes through my scope. At this point another bird walked into my scope view
and it was immediately obvious to me as a non-breeding male McCown's. Structure
was the same as the previous bird, but this one had a black breast band and a grayish belly. At times I could see chestnut in the shoulder. After I had more time to watch them and consult my field guides, I am confident that the first bird was a winter plumage female McCown's. I am not 100 percent sure on the total number of males, but at least 2 because I had two males in my scope at one time later in the day. There could have been more though because they were flying around quite a bit with the horned larks (see photos) |
Song or call & method of delivery: | n/a |
Behavior: | Mixed in with a large flock of Horned Larks. Appeared to be picking at seeds in the gravel and bare ground |
Habitat: | nearly bare ground with almost no vegetation bordering agricultural fields. The area was mostly under snow with areas that the snow had been blown off leaving bare ground. |
Similar
species and
how were they eliminated: |
Different size and structure than Horned Larks, plus the plumage differences
(see notes above). After an hour or so of watching the flock of Horned Larks I
got pretty good at finding the Longspurs. Even when they had their heads down
the back on McCowns appeared much more streaky than
the Horned Lark. The black breast and grayish belly are distinguishing characteristics eliminating other longspurs. Also compared to the other longspurs they showed less contrast in the face pattern and no noticble dark auricular spot. I did also observe a Lapland Longspur in the same flock so it made a good comparison. |
Previous
experience with this & similar species: |
Seen multiple times on breeding grounds in Colorado and Eastern WY and probably about half a dozen times in the winter. |
