4. [GO] Lams Philadelphia (Orel). Bonaparte's Gull. 



Rare migrant. One record April 16. 1903. A flock of one bnndred 

 "gulls" of three sizes was reported in April, 1902, by J. J. Batchelor. 

 From his descriptions I concluded that these were either Porster's or the 

 common Tern, and Bonaparte's and the Herring Gull. When these birds 

 appear so far from any large body of water it is always after a [period 

 of very high winds.

In late years, however, the Fish Duck has become a common spring 

 visitor to the reservoirs. . '
