I received a question in a private post about where the C. Goldeneyes are nesting at Langdon Lake: natural cavities, trees, or possibly in cavities in cliffs, and thought I would reply to the whole list. Only the west side of Langdon Lake (a small, privately owned reservoir) is public land - USFS Woodward Campground. The rest of the lake and lake shore are private and posted, occupied by homes and cabins. The vegetation around the lake is mature Englemann Spruce forest. The topography is relatively flat (no cliffs within 1.5 miles. Near the SW corner of the lake, someone has put up 3 Wood Duck nest boxes. The boxes are mounted on trees, and the goldeneyes are apparently nesting in those boxes. But I have not actually seen the ducks at or in the nesting boxes. The boxes are on private land, and there could be more boxes that are not visible from the campground. No other cavity-nesting ducks breed at the lake - Mallard is the only other breeding waterfowl. Pileated Woodpeckers and flickers nest in the vicinity and could also provide nesting sites for the goldeneyes.
