July 17 Eagle Cap & Glacier Pks, Wallowa & Union Coz., Oregon (cont.)
1:40 PM I heard a Rosy Finch and at 1:50 PM one was seen
toward the top of the cliffs. I circled E. around to
the top of the cliffs, arriving at 2:10 PM. At 2:40 PM
a Rosy Finch flew W. past the 2 dykes & landed. I
shot it & it promptly fell and bounced 400 ft. & landed
out of sight in a narrow (6 inch), but very deep bergschrund,
where I could not retrieve it. Between 3 to 6 PM,
seven additional Rosy Finches were seen. I shot at 5
of these and retrieved 3 by fancy engineering on the
cliffs. One apparently fell into the bergschrund and
another should have been in plain sight on a wide
ledge, but wasn't. Thus 3 were collected, but many
were seen; the most anywhere in the Wallowa Mtns.
The cliffs here are extensive, the snow is the most
extensive seen anywhere in these mtns, but perhaps most
significant, there were numerous ledge covered with
vegetation & moist ground & several nearby meadows, etc.
Elkhorn Pk seemed to lack these feeding areas
this year due to deep snow cover. Eagle Cap is basically
rocky talus & moraine with little turf for feeding
except the NE ridge where the bulk of the birds were
seen.
It should be noted that both 2 Rosy Finches had
full buccal pouches suggesting that they were feeding young.
Males appeared to have pouches (#178, 183 at least) but were
empty except #176 which had a full pouch. This extends
Miller's observations on the presence of pouches to male birds.
