Lesser Goldfinch
Carduelis psaltria
Crew Ranch, adjacent to Quarry Station of Dunbar National Monument (Unit No. 214)
Elevation 5000 ft.
June 15 At 06:55 this morning I saw a ? fo into a cottonwood (8'dbl, 22' high)
on N. extremity of a small grove (A-10 trees) about 30' up drainage from my mist
net. It climbed amongst some leaves about 15' above ground and seemed quickly
to disappear. I approached to find her in a nest built on a shallow
clotus created by the terminal radiation of three groups of pistoles. I walked
to a position on top of the low canyon wall and stood from a distance of 40 feet
near
to simultaneously feeding of this bird by two ?'s, one malely black on the back
mostly
the other appearing green-backed. The dark-backed bird fed the female first,
immediately followed by the green-backed bird. The former flew out. I noticed not
which direction was taken, while the latter fed the female. It's was at 07:06;
[illegible]
this was repeated at 07:14 and 07:32, and always the black-backed bird
fed the female first. What was fed I could not say, because two males
screened most of the nest. I alerted all of the sitting bird when they came to the
nest. The males remained away from the nest at least until 08:15, when I left
to check open canies with elkheres in this canyon riparian setting on the south
part of the road. I practiced one mist net and pair of fudges birds almost
unbunted to the nest, but through 17:00 I caught none of the three. At
14:20 I shot both males at the nest, the surely black-backed bird being
come in about 25 seconds before the second male. As soon as the second male
came in, I shot, and killed both. The female fed the nest, but was also
successfully shot when she returned 18 min later. The nest had six eggs and eggs.
I have seen goldfinch three elsewhere (Washington Ranch, Eddy Co., New Mexico
and Blackrock Bosque, Zuni Reservation, McKinley Co., New Mexico, some right
by said), but I never suspected a feeding menace to this!
