Marshall (1942) Stelgidopteryx ruficollis J. Olmegg Noted probably was over swamps and grass at SW corner lake Chilata Only in the same deeep gorge with the Collared Swift After discovering the swifts roosting crevice under a large boulder over which the entire stream fell I went back in the daytime I noticed a r-rw swallow cling below a little hole on the lowest vertical face of the boulder and about 10 ft above the pool. This was a round hole about 1 1/4
