FAMILY LARIDAE

San Carlos, in extreme west Panama Province, 40 or more came 

 along shore in late afternoon in pursuit of a school of minnows. 

 I took 3 here. They appear at times at Farfan Beach and off the 

 causeway near Fort Amador, in the Canal Zone, and also at Panama 

 Viejo. I have seen one over the wide arm of the Rio Chagres op- 

 posite Gamboa, and there is record of one on Gatun Lake at Barro 

 Colorado Island. 



The only report for the Caribbean coast is of one taken by Wedel 

 at Perme, San Bias, on November 30, 1929. Griscom in recording 

 this (Bull. Mus. Comp. ZooL, vol. 72, 1932, p. 322) wrote, "I am 

 aware of only one previous capture ... in Panama," a statement 

 that I have been unable to verify.

These are terns of the oceans that nest on small islands and range 

 over the open sea. Two of the recognized subspecies are recorded 

 from Panamanian waters, where, however, they are little known.
