Detalhes da observação
The three recordings attached capture the calls heard over the course of ~28 minutes pre-dawn during this observation. Early in the observation I heard a relatively rapid series, captured in ML615954500 (made at 5:10am). Subsequently, a slower and longer series of deeper, tremulous notes was given. This series started out clearer and then became more tremulous as it progressed, increasing in pace part-way through. This second call type is captured in ML615954498 (which truncates the beginning of the series, as my mic was not yet on; 5:13am) and ML615954499 (which is a bit softer, but captures the full series of notes in a call bout; 5:26am). These all may represent the same individual, with the bird transitioning from a rapid series (ML615954500) to a longer, slower series (ML615954498, ML615954499). Or multiple birds, potentially of two species, may be involved.
