eggs on the loth of April. It was placed 60 feet high on a knob projecting 

 from the face of a perpendicular clift. The birds were arrant cowards and 

 offered no remonstrance while their nest was being pillaged. 



40. Aquila chrysaetos. Golden Eagle. — Fairly common throughout 

 the county. This Eagle is a familiar feature of our wildest mountain 

 scenery, and is especially likely to turn up after one has killed a mountain 

 goat. One pair breeds within 200 yards of a farmhouse near the 

 Okanogan River. 



41. Haliaeetus leucocephalus. Bald Eagle. — Comparatively rare. 

 Onlv three or four individuals were noted during my stay. 



42. Falco mexicanus. Prairie Falcon. — Next to the Sparrow Hawk, 

 the commonest Raptor. One coulee in particular, which connected two 

 large terrace tops or flats along the Columbia River, and whose walls 

 were beetling cliffs towering a thousand feet high, sheltered half a dozen 

 pairs of these Falcons. The favorite breeding site is some inaccessible 

 niche in a perpendicular rock-wall, which faces some open situation. 

 Except in places where the}' congregate for sport, the presence of these 

 birds is likely to go unsuspected, until the screaming of the falconets 

 betrays the nesting site. 



43. Falco columbarius. Pigeon Hawk. — One specimen shot. Prob- 

 ablv not uncommon. The relation of this bird to Richardson's Merlin 

 was not satisfactorily determined. 



44. Falco sparverius deserticolus. Desert Sparrow Hawk. — 

 Abundant on the lower foothills and in open situations. Less common 

 in the inountains. 



45. Pandion haliaetus carolinensis. American Osprey. — Common 

 along the Columbia River and tributary streams. 



46. Asio wilsonianus. American Long-eared Owl. — Two or three 

 pairs will be found in any considerable swamp. Eggs were taken in April 

 and in June. 



47. Bubo virginianus saturatus. Western Horned Owl. — These 

 birds were seen only at the upper end of Lake Chelan. 



48. Speotyto cunicularia hypogaea. Burrowing Owl. — Not a char- 

 acteristic bird, but still to be occasionally met with in the semi-arid and 

 treeless portions at lower levels. 



49. Ceryle alcyon. Belted Kingfisher. — Not a common bird, except 

 on Lake Chelan where it winters. 



50. Dryobates villosus harrisii. Harris's Woodpecker. — Not com- 

 mon. 



51. Dryobates pubescens homorus. Batchelder's Woodpecker. — 

 Materials are not at hand for the stricter determination of this sub- 

 species. The bird is fairly common. 



52. Xenopicus albolarvatus. White-headed Woodpecker. — This 

 bird was seen only twice. The last time it was found nesting at an altitude 

 of 3000 feet. There appears to be nothing unusual about its nesting 

 habits, except that in this instance the eggs were all dotted with pitch.
