Subject: [obol] Re: Goldeneyes
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.
