Mount Mazama Bird Notes

boulders of pumice along the bank, when dislodged, fall into the current and 

 go bobbing down stream like corks, I encountered in a forest-opening an im- 

 mense wandering flock of Warblers and Bush-tits. I have often encountered 

 these mixed flocks in the foothills, but never have I met a larger one, or one 

 more compact. I think that I watched them for fully half an hour, as they 

 drifted past through the chinquapin brush. As far as I was able to determine, 

 Bush-tits composed about one-fourth of the flock. Of the Warblers, there 

 were three varieties: the Calaveras and Lutescent Warblers, combined in 

 about equal numbers, constituted another scant fourth, while the remainder 

 of the flock was composed of Hermit Warblers. As before this I had met but 

 a single pair of Hermit Warblers, this early morning flock was to me an 

 especial treat. 



A single pair of Western Evening Grosbeaks, flying over just as we were 

 about to start again, finished my Mount Mazama observations. It was a 

 most satisfying jaunt, and, although I had learned much concerning bird-life 

 zones, there remains underneath, and probably always will, a never-endingWhy? 



The Tree Swallow on Long Island 



By J. T. NICHOLS, New York City 

 With Photographs by Dr. Frank Overton 



THE Tree Swallow ordinarily does not nest near 

 New York City, where it arrives on its southward 

 migration the beginning of July; but on the east- 

 ern portion of Long Island it is locally a not uncom- 

 mon nesting-bird. The present note deals with its occur- 

 rence on the south shore of the island. 



About June 1, 191 2 (May 27, May 29, and June 2) 

 Dr. Frank Overton, of Patchogue, found a pair going in 

 and out of one of several old abandoned hydrants by 

 the side of a road through deserted farm land overgrown 

 with low pines. The opening to the nest was only a 

 couple of feet from the ground. The hydrant in which it 

 was placed was in East Patchogue, about one-half mile 

 from Great South Bay and within 400 or 500 feet of a 

 pond. The accompanying photographs by Dr. Overton 

 were taken at this time. From him I learned that Tree 

 Swallows nested at this spot in succeeding years, that in 

 1 91 5 there were two or three pairs, and that formerly 

 Bluebirds nested in the hydrants. He had not seen 

 the Bluebirds for several years. 



On June 15, 1914, the writer found his first Long Island Tree Swallow's
