Vol. X.] MAILLIARD— BIRDS, MAMMALS OF SISKIYOU COUNTY 83 



ent, or apparently were coming in during our week's stay. 

 Among the late comers were the Brewer's Sparrow and Gray 

 Flycatcher, the former in the sage brush and the latter in the 

 willows along the stream. 



Gilchrist came across an Osprey's nest on top of a tall pine 

 stub, with the old birds in attendance, the secret of their pres- 

 ence here being the number of fish in Lake Orr, a small body 

 of water a short distance west of Bray, and easily available 

 to them. 



Some ducks and other waterfowl breed about this lake and 

 the Yellow-headed Blackbird nests here abundantly. The sage 

 brush near the lake is higher than the major part of it elsewhere 

 in the neighborhood and here was the only place where we 

 found the Western Vesper Sparrow. Holman ascended Mt. 

 Orr, close by and probably about a thousand feet higher than 

 the town, and there found the Yosemite Fox Sparrow breeding, 

 the identification being from specimens he brought in, this ex- 

 tending slightly the known range of this species. 



A female Cedar Waxwing was seen on June 2, calling from 

 the top of a small willow. This was taken and showed no sign 

 of breeding. On June 3, Gilchrist came across a couple of Cali- 

 fornia Evening Grosbeaks, one of which was secured. This 

 proved to be a female with the ovary just commencing to swell, 

 the largest ovum being about 1.4 mm. in diameter. 



Here also, on June 2, we heard our first Pacific Nighthawks 

 for the region, as they carried on their courting antics high 

 above our heads. None came low, contrary to some of my 

 previous experiences, when they had descended close enough 

 for us to secure specimens. The Gairdner's Woodpeckers here 

 seemed to have rather more left of their tails than some we had 

 been taking. One of these taken at Weed had nearly half of 

 the tail feathers worn away, leaving a sort of double crescent 

 effect, the shaft of the main rectrices being only 32 mm. long, 

 as measured from the end of the pygostyle, instead of some- 

 thing over 50 mm. I have placed this woodpecker from the 

 Shasta Valley region with gairdneri, but it leans very strongly 

 toward tnrati, being anything but typical. Near the lake Mr. 

 Holman noted a Magpie, the only one seen, but failed, after a 

 long chase, to secure it. The Poor-will was in evidence here,
