| Popis: | Noisy Pittas and Green Catbirds showed a marked increase in calling associated with the breeding season and then declined to much lower levels in winter. Eastern Whipbirds had a peak of calling at the start of the breeding season but then maintained a relatively high level throughout the year. All three species had a peak of calling around sunrise which then declined during the day with a slight increase around noon and a greater increase at sunset. In Noisy Pittas, the secondary peaks at noon and sunset were much larger than in the other two species. Noisy Pittas, a suboscine in the suborder Tyranni, had a similar temporal pattern of calling to that found in oscines. |
