^66 Bendire o» the Habits of Glaucidium. [October 



Sialia arctica. — Common migrant : arrived March 27 in consideiable 



numbers. Breeds, but very sparingly, near the Fort; higher in the 

 mountains it is common, and there replaces mexicana. 



Tringa minutilla. — This species was accidentally omitted from the first 

 instalment of the present paper. I took a single specimen Jul}' 10. 



NOTES ON THE HABITS, NESTS AND EGGS OF 

 THE GENUS GLA UCIDIUM BOIE. 



BY CAPT, CHAS. E. BENDIRE. 



The genus Glaucidiui7i was instituted by Boie in 1S26. Only 

 two species and one additional subspecies are found within the 

 limits of the United States, as far as is known at present. These 

 are 



Glaucidium gnoma Wagler, the Pygmy Owl. 



Glaucidium gnoma californicum Sclater, the California 

 Pygmy Owl. 



Glaucidium phalsenoides (Daud.) , the Ferruginous Pygmy 

 Owl. 



The true G. gnotna is found in Mexico, throughout the 

 middle province of the United States, north to Oregon (Fort 

 Klamath and Camp Harney) and Coloi'ado. G. gnoma cali- 

 fornicum is restricted to the Pacific Coast proper, between San 

 Francisco Bay and British Columbia, inclusive. These little 

 Owls, I believe, are resident throughout the year wherever 

 found. 



The general habits of the Pygmy Owl are by this time pretty 

 well known, and there remains little for me to add to their life 

 history, that is really new. It is a well-established fact, that it 

 is quite diurnal, and hunts its prey, to a great extent at least, 

 during the daytime, its food consisting not alone of grasshoppers 

 and other insects, as some of the earlier naturalists surmised, but 

 also of birds and the smaller rodents, some of the latter consider- 

 ably heavier than itself.
