one bird mixed with Type 10 RECR flock
觀察細節
**very rare (possibly the 1st for New Jersey?); single bird that made plinking flight calls within a flock of Type 10 birds; noticed it when listening to my recording later on; the spectrogram shows the distinctive sharp “V” shape of Type 4; flock headed south across Delaware Bay to DE; audio recordings
