觀察細節
During a seawatching session from a coastal cliff, we detected a significant migration of swifts in active northwards migration following the seaside. Among them, 3 individuals stand out because of their different behavior and flight action. They showed up 2 times within one hour and visited small caves in the cliffs. They were blackish, with no evident pale patch in the throat. They had a very active flight and looked streamlined. Observed together with Jerry DeMeaco and Anne Bell. Additional photos in due course.
