 Bonaparte's Gull. 



PLATE 4, FIG. 1. 



Adults. — Length, 12-14. Wing, 10.25. Back and wings, pearl gray; entire 

 head and throat, plumbeous ; hind neck, white ; three outer primary feathers 

 mostly white with black tips, the next three with subterminal black areas, and 

 all but the first two with small white tips ; rest of plumage, white ; bill, black. 



In winter — Similar, but head and throat white with a little gray on the back 

 of the head and ear-coverts. 



Younger birds have a terminal black band on the tail, and dusky mottlings on 

 the ear-coverts. 



Eegular spring and fall migrant and winter resident, in some sea- 

 sons at least. 



The original specimen was procured on the Delaware about 1815. 

 Turnbull (1869) regarded the species as "not uncommon," and Krider 

 says, "Found on the Delaware in April and October ; not common." 



Messrs. Stackpole and Wiegman reported 67, ten miles off Long 

 Branch,^ Decemljer 31st, 1904, and 115 were observed in the same 

 vicinity December 25th, 1908.- Apparently, like the Kittiwakes, they 

 keep well off shore, as I find very few records of capture. 



Mr. DeHaven secured one at Atlantic City as early as August 21st, 

 1892,^ and Dr. W. L. Abbott shot one in Cape May county November 

 28th, 1879.
