Myers phil 1974 Journal 3 20 Jan. Academy Bay, Isla Santa Cruz, Galapagos Is., Ecuador G. scanders called cactus finches were seen frequently feeding on the pollens of cactus flowers, & their faces were closely smeared with pollen. Some of the G. fortis had beaks full of what appeared to be cactus pulp. The finches are generally calm-iant. We certainly saw far more than we caught, even right around the nest. They move in mixed flocks, thus any area is seldom completely without finches. The yellow warbler seem to move with them, tho the mockingbird seem to keep apart. All birds were surprisingly active during late morning & mid afternoon. We caught finches at all times of day. The early morning period was most productive, but the difference between early mornin catch, to that of other times of day was not as great as it has been in either [illegible] temperate or tropics areas I've settled - a facts of 2 to 3 at most. The finches respond well to squeaking & "pishing" - almost to the point of landing on the observer. The warbler & flycatchers also are susceptible. The best strategy for catching birds however was to find an that squawked a lot (some individual species sex & of any sp seem to be more noisy than others of the same sex or sp) & hold!
