As is usual, it is illustrated almost entirely by photographs 

 taken by the writers of the articles, and many of these are 

 of very high merit. It is impossible to do much more than 

 mention some of the more important contributions in a 

 short review of this nature. 



Dealing with single species, Mr. H. J. Rust writes on the 

 nesting of the Sharp-shiuned Hawk {Accipiter velox) in. 

 Idaho, illustrating his notes with a very good series of 

 photographs showing the gradual development of the young 

 birds up to the age of 23 days, when they are already able 

 to fly and have lost most of their original downy covering. 

 Similar papers by Mr. J. B. Dixon on the history of a pair 

 of Pacific Horned Owls [Bubo virginianus padficus) in San 

 Diego Co., California, by Mr. D. R. Dickey on the nesting 

 of the Spotted Owl (Strix occidentalism in Ventura Co., 

 California, and by the Treganza brothers on the Snowy 

 Heron (^Ardea candidissima^ in Utah are also well illustrated. 



Of local lists Mr. G. Willett writes on the birds of Sitka, 

 Alaska, Mr. S. G. Jewett on birds from Netarts Bay, 

 Oregon, Mr. A. A. Saunders on the birds of Teton Co., 

 north Montana, and Mr. H. A. Edwards on birds from the 

 Sierra Madre in southern California. 



The only article dealing with birds outside the Nearctic 

 region is that o£ Mr. A. van Rossem on the life-history and 

 breeding-habits of the Derby Flycatcher [Pitangus sulplmra- 

 tus derbianus) in San Salvador, Central America. During a 

 short excursion to Fryppe, at an elevation of 3700 ft. in the 

 Sierras of California, Mr. M. S. Ray was fortunate enough 

 to find the nest and eggs of the Hermit Warbler (JDendroica 

 occidentalis), one of the rarest of all the western Warblers, 

 as well as those of the Sierran Hermit Thrush (Hylocichla 

 guttata sequoiensis) and the Saw-whet Owl i^Cryptoglaux 

 acadica). 



Mr. J. E. Thayer gives us some information about the 

 nest and eggs, probably the first authentic ones taken, of 

 the Kittlitz Murrelet [Brachyramphus brevirostris), which 

 he obtained from Pavloff Bay in the Alaska Peninsula.
