8 THE AMERICAN MIDLAND NATURALIST 



48. Baeolophus bicolor. Tufted Titmouse. 



Two records — May 18, 19 14, and May 26, igi6. This seems to 

 be, in a way, rather remarkable, because one would expect the 

 species in such a place during the winter rather than during the 

 breeding season. 



49. Cyanocitta cristata cristata. Blue Jay. 



Tolerably common from September to early May, but most 

 frequently observed in September. We have not noted it in the 

 fall earlier than September 5 (19 15), nor in spring later than May 

 2 (1915)- 



50. Corvus ossijragtis. Fish Crow. 



Another very common species, of regular occurrence from August 

 to May, but not noted in June or July. 



51. Corvus brachyrhynchos paulus. Southern Crow. 



One of the most frequent birds from October to May, bat not 

 noticed in summer. Doubtless some of the individuals seen during 

 the winter months belong to the common American Crow, Corvus 

 brachyrhynchos brachyrhynchos, but as no specimens were taken 

 it is, of course, impossiole to verify this probability. 



52. Lanivireo Uavifrons. Yellow-throated Vireo. 



A tolerably common summer resident, noted from May i (1914) 

 to September 2 (191 7). It was heard singing on August 23, 19 14. 



53. Vireosylva gilva gilva. Warbling Vireo. 



For this uncommon species in the city of Washington we have 

 but a single record — May 19, 19 14. 



54. Vireosylva olivacea. Red-eyed Vireo. 



For so common a bird we have surprisingly few dates. They 

 are: May 11 and 21, 1916; May 23, 1915; May 28, 1914; and 

 September 24, 1914. It was also heard singing on August 23, 1914. 



55. Bombycilla cedrorum. Cedar Waxwing. 



Noticed occasionally from March 18 (191 6) to June 2 (1916), 

 and from August 19 (191 7) to September 26 (191 7). Rather 

 strangely not seen at any other time of the year. 



56. Iridoprocne bicolor. Tree Swallow. 



A flock of 10 was seen flying over high in the air on August 23, 

 1 916, but no others have been observed. 



57. Hirundo rustica erythrogastris. Barn Swallow. 

 Seen once — on May 10, 191 7.
