1^6 Dawson, Birds of Ok(xnoga7i Co., Wash. \_k^x\ 



64. Tyrannus tyrannus. Kingiurd. — Not nearly so common as 

 7\ verf/ccrh's, hut of general distribution along the terraces and lake 

 borders. 



65. Tyrannus verticalis. Arkansas Kingbird. — Abundant. You 

 may expect to tind a vociferous pair nesting among the out-buildings of 

 any farm-yard. At Chelan soine large fir trees along the i-i\'er front con- 

 tained several nests apiece. 



66. Sayornis saya. Say's PucF.nE. — This bird is the frequent associate 

 of the Prairie Falcon, preferring to haunt just such cliffs as the nobler 

 bird selects for nesting sites. Here it takes up its station about the 

 middle of March, and it is rarely to be found at any considerable distance 

 from home. 



67. Contopus borealis. Oi.iVE-siDEn Flvcatciikr. — Not a common 

 resident even in the higher ranges where it is found, but conspicuous on"' 

 account of its clear, penetrating note, — swee-c/tezv, szvet'-c/ie-v, deVwered 

 with great energy from a high branch in some fir tree. 



68. Contopus richardsonii. Western Wood Pewee. — This bird is 

 perhaps the most conspicuous species of the fir-clad, precipitous shores of 

 Lake Chelan, for with scarcely an interval along the shore line, its 

 lugubrious notes can always be heard,. The breeding range, so far as 

 observed, is confined to the lake shore, where the birds choose some 

 exposed situation, and set a dainty, heiupen cup at the fork or foot of a 

 bare limb, preferabl\' of a sapling. Fresh eggs were found as late as 

 July 28. 



69. Empidonax difficilis. Western Flycatcher. — The western 

 Empidonaces are all at home on Lake Chelan. This species was noted 

 only at Graham's Harbor, where it breeds, but it doubtless occurs in 

 suitable localities throughout the county. Note a soft, sibilant, pis' -wit. 



70. Empidonax traillii. Traill's Flycatcher. — Abundant in the 

 lower mountain-valleys and couldes. It is the commonest of the Empi- 

 donaces wherever found, and was recorded up to 1700 feet. One of its 

 common notes ifi pison. 



71. Empidonax hammondi. Hammond's Flycatcher. — Rare. 

 Found chiefly about isolated springs where it is likely to be the only 

 member of the genus present. Its note is a brisk seivick, se-vick, and at 

 rarer intervals, siviic/i-00, or srvecehoo, — the latter harsh and unresonant, 

 and so easih distinguished from the penetrating note of the Olive-sided 

 Flycatcher. 



72. Empidonax wrightii. Wright's Flyc-^tcher. — Several speci- 

 mens secured on Lake Chelan. It was found breeding at Graham 

 Harbor and near Stehekin. Note a soft, liquid s-vit. This record 

 extends the northern range of the species. 



73. Otocoris alpestris leucolsema. Pallid Horned Lark. — One 

 individual wintered near Chelan. Easily distinguishable from 



74. Otocoris alpestris merrilli. Dusky Horned Lark. — Found 

 spaiinglv (ui the lower bunch grass hills. About jo indi\iduals were
