觀察細節
Ten in flight, often passing close to the building in smaller 'screaming parties'. Noticeably smaller and more agile than Pallid Swift with faster wingbeats and much higher-pitched calls. Darker throat as well. Two adults entered a nest and sang a duet, and at that moment it was possible to hear at least two nestlings begging in response. Have sound recordings of this.
