THE CERULEAN WARBLER A SUMMER RESIDENT NEAR 

 WASHINGTON. 



By William R. Maxon. 



There are, so far as I have been able to ascertain, only three definite 

 records of the Cerulean Warbler {Dendroica rara) for the vicinity of Wash- 

 ington, D. C. On May 5, 1888, Dr. Hasbrouck took a male in the Rock Creek 

 Park.* On May 11, 1890, the same collector secured a second specimen, a 

 female, on the Virginia side of the Potomac, f Two or three years ago, Mr. 

 Paul Bartsch, of this city, took an additional specimen on the Potomac flats 

 during the fall migration. 



On May 29, 1902, I collected an uncommonly bright male at Plummer's 

 Island, near Cabin John, Montgomery County, Maryland (some seven or eight 

 miles from Washington), and the attendant circumstances seem to admit of little 

 question that the bird was resident where taken. I first observed this in- 

 dividual on May 22, having been attracted by the unusual song which seemed 

 more like a variant Parula's than that of any other warbler. Though I had 

 several times visited a colony of the Cerulean near Oneida, New York, and 

 thought myself tolerably familiar with their songs, I had no idea of this bird's 

 identity; and as it kept well to the tops of the highest trees 1 was unable to 

 get a satisfactory view or to use my small pistol with effect. Early on the 

 morning of the 29th I again heard the strange song and found the bird not only 

 in the same vicinity, but actually flying back and forth occasionally between the 

 identical two trees frequented just a week earlier. The unusual song recalled 

 nothing of my Central New York experiences, and it was not until I had shot 

 the bird from some lower growth, into which it had for the first time dodged, 

 that I learned with some chagrin its identity. I would hardly have expected 

 to find so rare a migrant in this vicinity a summer resident.
