expect nests to be less bulky in quonset huts
since they would be added to less often. If any-
thing, the opposite appears to be true: the largest
nest masses have usually been in quonset huts.
The table below summarizes the figures.
Structure Type
Quonset Other Buildings
% [illegible] with new nests 9.8 26.7
% with nests (old + new) 37.3 58.5
% with good nest sites
that have new nests 20.0 40.8
% with good nest sites
that have nests (old + new) 85.0 88.9
Four dead rosy finches were found in a
55 gal. drum full of water located next to a window
in a quonset hut that contained an old nest on
a shelf near the same window. It was not

possible to be sure of the age of the birds, but they were
