Wolfson 1938 Baile Swallow June 8 1/4 mile N Warrend Klamath Co., Oregon. Colony of swallows nesting in a pile of crushed rocks used for road mending or building. Pile was 12 feet high and all nesting holes were easily accessible. It was about 60 yds long in a NW direction and 30 yds W of the main highway. Several piles of larger rocks were at one end but were not used. There was vegetation of grass, sedges etc on top of this pile and also gopher workings thereby indicating that the pile had been there for several to years or at least one. There were about 120 holes some of which were incomplete and evidently were found not suitable. Those occupied varied in their nests; some having eggs on bare surface, others on 1/4 deep base of dried grass and feathers. Two sets of fresh eggs,- about 1-2 days old -were collected. Holes exposed to W(?) July 18 Same location as above: Swallows still present - probably have young to be fed - did not examine holes again.
