Journal 86 R.E.Johnson 1967 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.
