Richardson 1937 Plumbeous Buseh-tit (Poalhybarna plumbra) May 27, 1937 driving of 20-mi G. into Womer Valley, Oregon Two birds seen and collected / probably each was one of a pair. These were the only Bush- tits seen or heard by any of us so far / so the species may be tentatively considered rare- common. The type of habitat, that of high sagebrush (c 3-6') is barely represented in the canyon proper, but here at the broad outer mouth of the canyon, is fairly extensive (perhaps 10 acres). Both birds were foraging in sagebrush (probably Artemesia tridentata). May 28, 1937 - W rim 20-mi G., Womer Valley, Oregon Two bush-tits were again collected but this time high up in region of junipers. This argues against this species being closely limited by altitude but the habitat may remain essentially the same for Artemesia tridentata extends all the way up the sides of 20-mi G. canyon. These two specimens probably repros- sented 2 pairs (evidence being, in part, that & 69 as & 67 of May 27, had a large broad patch). However, one bush-tit was heard later in the day by camp and seemed to be traveling down canyon probably not breeding yet. The data on iris color from the four specimens collected by now is of interest. Both & 67 & 69, had a completely yellowish-white
