J Davis 1957 6. Playa de Santiago, 1& mi. NW Mayanillo, Colima Oct. 28, 1957. One Brown Heron. At Playa de Santiago, Common and Black Terns were numerous, fishing over the waters. Willet and Brown Pelicans noted. One Belted King-fisher seen. One Brown Booby seen, circling repeatedly over the water, and one diving, apparently at a fish. Blake (Birds of Mexico, p.19) notes this species as "accidental or casual at Mayanillo, Colima," but on previous visits to Mayanillo & Playa de Santiago in 1954 and 1955, the species was noted every day, and on one day in 1955, 6 were counted between Playa de Santiago and Mayanillo Harbor. Previous visits were in December, and it seems apparent that the species occurs regularly, in low numbers, in the Mayanillo region, in fall & winter. Oct. 29, 1957. Hunted along road 1& mi. NW Mayanillo, the second road followed yesterday. Elevation here, given on my labels as 50± ft, probably range from 50 to about 200 ft. Again, I heard E. difficilis sing, one bird for 30+ sec. Songs heard yesterdays today are indistinguishable from those given by E. & d. difficilis in California. New birds seen today, not collected: Turtur rufa falliatus, Musisordessf. The two frogs collected may have been a pair, as both were called in same area. The Aarezona collected was one of two in same tree. Aratinga & Forpus are in large flocks at this time of year, but Amazone is always either solitary or in duos, suggesting permanent pairing. The
