Part 13

Evidence for breeding is given for 20 species for the first time and extensions of the known breeding seasons are presented for 41 species.

Fourteen genera, representing about 19 species, of Mallophaga are reported for 20 different species of bird hosts.

At Pisté and Puerto Juarez, species of birds such as the Blue Honeycreeper and the Red-capped Manakin, normally thought of as characteristic of more humid areas, were found breeding in numbers near cenotes. However, they were not seen to venture far into the surrounding deciduous forest. The availability of suitable habitat brought on by the rainy season and the regular occurrence of cenotes helps to explain the presence of such species far outside the Rain Forest zone.
