PROGNE MODESTA Gould 



Galapagos martin 



Prognc modesta Gould, Zool. Voy. Beagle, pt. 3, Birds, July, 1839, p. 39, pi. 5. 

 (James Island, Galapagos Arcbipelago.) 



A pair was obtained at Eden Island, near Indefatigable, June 24, 

 1929. 



Martins were seen almost daily when we went ashore on the more 

 open and level stretches of Indefatigable and Seymour Islands. Un- 

 fortunately whenever they appeared the distance was too great or 

 the time was inopportune to capture them. At Daphne Island, 

 June 23, numbers were observed about the cliffs, where they nested 

 in crevices in close association with Galapagos shearwaters, noddy 

 terns, tropic-birds, and fork-tailed gulls. The following day Eden 

 was visited and numbers were seen either entering or leaving their 

 nesting crevices in the cliffs. Two specimens were secured as they 

 flew over the boat.
