THE CONDOR 
Vol. XV 
willow thickets along Trout Creek. Here I found the Traill Flycatcher {Einpi- 
donax ti'tviUi tradh) and the ellow Warbler (Dcudroica acstiva brewstcri) ver)' 
abundant, six nests of the former and four of the latter being’ located. Those 
of the flycatcher were all placed in willows close to the water at an average height 
of four feet above the ground and were remarkably similar in construction, being- 
made of bark strips, grasses and vegetable fibers, and lined with horsehair. AH 
the nests held either three or four eggs, which varied from fresh to some well 
along in incubation. The nests of the warbler, being a much earlier nesting bird, 
contained both eggs and young in various stages.

The last nest, which I found late in the afternoon of July i, important only 
on account of the extremely late date, was one of the Belted 
Kingfisher {Ccrylc alcyon) in a sand bank six feet above water and 
dug to a depth of four feet seven inches. The eggs, seven in num- 
ber, were but slightly incubated and lay on a bed of small fish bones. The sit- 
ting bird did not leave until I was almost through excavating. Previous nests 
of the bird in the I^ake Valley region have all held large young by the first of 
June.
