Montana ; and Mr. E. R. Warren on Ins observations in 

 South Park, Colorado, 



The nests and eggs of Cypseloides niger horealis are 

 described by Mr. W. L. Dawson. Although far from being 

 an uncommon species in western America, there has always 

 been a great amount of mystery about the nesting habits o£ 

 the Black Swift, and very few authentic eggs are known 

 in collections. A Mr. A. G. Vrooman of Santa Cruz in 

 southern California announced some years ago (Auk, 1901, 

 p. 394) that he had taken a single egg of this species on the 

 damp bare earth of a sea-cliff. This seemed so improbable a 

 place for a swift to nest in, that little credit was given to the 

 story. Recently Mr. Dawson accompanied Mr. Vrooman on 

 an expedition along the sea-cliffs near Santa Cruz, and was 

 rewarded by finding the nest and eggs and photographing 

 them in situ. Another interesting nest, the finding of which 

 is described, is that of the White-tailed Ptarmigan [Lagopus 

 leucurus), which breeds at an elevation of 11,500 feet in 

 Colorado. Mr. Bradbury found the nest in a swampy place 

 and the eggs lying in two inches of snow water ! 



Of new forms, Mr. J. Mailliard describes a new subspecies 

 of Redwinged Blackbird {Agelaius phoeniceus aciculatus) 

 from Kern County, California ; it appears to have a very 

 restricted distribution, but Mr. Mailliard is convinced of its 

 distinctness. 



Mr. L. B. Bishop proposes to distinguish a new race of 

 the Savannah Sparrow, Passerculus sandwichensis brooksi; 

 it is resident in south-west British Columbia, near the coast, 

 and sometimes migrates south to California. It was first 

 obtained by Capt. Allan Brooks, who is now with the 

 Canadians fighting in France,' and was named after him. 



In the asphalte beds at Rancho La Brea there have been 

 found over a hundred thousand bird-bones, now in the col- 

 lection of the Los Angelos Museum, and Mr. L. H. Miller has 

 discovered among them a curious tarso-metatarsus which he 

 states must have belonged to a " walking eagle." He names 

 the bird Morphnus daggetti sp. nov., and believes that it may 

 have been related to the South African Secretary-bird.
