NOTES: (Breeding Status: Not territorial? Cat: Song? Context: Advertising? Del. Rate: Normal? Gen. Climate: Humid. Cov. Density: None. Water Assoc: Pond? Weather: Mild breeze.) Although the flock also included a few Apus pacificus, I suspect most if not all of the calling birds were Apus affinis which greatly outnumbered the former species in the flock. Apus pacificus is a migrant in this area, whereas Apus affinis is a common breeder.
ML: Subject changed from Apus affinis to A. nipalensis to reflect current taxonomy. Jay McGowan, 29Nov2017.
