4. [60] Lanis phihidcltthia (Urd). Bonaparte's Gull. 



Rare migrant. One record April 10, 1903. A tlock of one hundred 

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

 From his descriptions I concluded that these were either Forster'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.

 visitor to the reserA'oirs.
