The pallid horned lark, Otocoris alpestris leucolaema (Coues), 

 is probably the prevailing winter form in Montana. The desert 

 horned lark was found regularly from the base of Mt. Mc- 

 Donald to the shore of Flathead Lake, generally feeding along 

 the roads, or flitting about in the vicinity of the pools. Most 

 of the specimens taken were young of the year. 



475. AMERICAN MAGPIE, Pica pica hudsonica (Sab.) 



Abundant in the thickets of the foothills and along the 

 streams; also in the dwarf trees along the shore of Flathead 

 Lake. Many nests of the spring were noted, some high in the 

 pines, though most of them were within reach without climb- 

 ing, in dwarf haws and similar growth. 



The magpie was not listed at Sin-yale-a-min Lake, but it was 

 noted at McDonald Lake. 



478 c. BLACK-HEADED JAY, Cyanocitta stelleri annectens 



Baird. 



This mountain form of Steller's jay was quite common in the 

 vicinity of Sin-yale-a-min and McDonald Lake. Such speci- 

 mens as were wanted were taken, for they did not manifest a 

 suspicious nature when the collector was near. All our speci- 

 mens were in very poor plumage, undergoing the moult during 

 our visit to the lake. 



484 a. ROCKY MOUNTAIN" JAY, Perisoreus cannadensis 



capiialis Ridgw. 



The Canada, jay in its Rocky Mountain form did not seem 

 to be common near our itinerary. One specimen was taken at 

 Sin-yale-a-min Lake while lurking in a fir clump near where 

 we were sitting, on the southern shore of the lake; its curiosity 

 perhaps led it to betray its presence. No other notes were 

 made regarding its occurrence. 



486. AMERICAN RAVEN, Corvus corax sinuatus (Wagl.) 



A family of this species had a home up the hillside on the 

 western shore of McDonald Lake. The noisy croakings were 

 heard throughout our visit, and the birds were frequently
