[cobirds] Walden Ponds, Boulder Co, White-faced Ibis, Golden Eagle

21 White-faced Ibis were still at Walden/Sawhill Ponds this morning. Highlight of the day, however, was a Golden Eagle by the trail with a beak full of down standing in a pile of feathers. The only flight feather I could see in the pile appeared to be a Great Horned Owl rectrix.
