观察细节
A Pterodroma petrel almost certainly of this species was heard at night flying over Robin Bush. The bird was heard to call around 15 times but was not seen. Subsequent analysis of the calls suggest this was a soft-plumaged petrel. Bird calls faintly twice on the audio - at around 3 seconds - and at around 16 seconds.
