The best habitat model for Gray Catbirds
suggested that detections increased with greater fruiting species richness (Table 2).
But as hundreds of twitchers flocked to see the Grey Catbird
- the first ever seen in Britain - they were devastated to find it had left again, still aboard the luxury liner as it headed for a two week cruise of the Mediterranean.
However, Gray Catbirds
also winter at Los Tuxtlas, and Winker (1995a) detected significant autumn diel gains in this species where none was apparent in spring.
To investigate the individual and synergistic effects of these variables, I will use the malaria parasite Plasmodium relictum and gray catbirds
The perch most often used by catbirds
was on this tree's trunk, which was ~20 cm in diameter, 3.
Species subjected to the same predators should benefit from recognizing each others' alarm calls (Hurd 1996), which may explain why the Hooded Warbler in the observation responded to alarm calls of Gray Catbirds
For example, 66% of Gray Catbirds
originally banded in winter were first recaptured in migration in a subsequent non-breeding season rather than in winter.
incubate eggs for approximately 13 days, which would indicate the nest was active by 7 July 2006.
were omitted from this portion of the study because they reject cowbird eggs.
Twenty-five male and 13 female Gray Catbirds
were mist netted and banded with U.
