Adult male Eastern Wood-pewee giving dawn song at 20-22 meters at 0509. Same individual as in ML167899251. Recorder HPF on at 80Hz, -12dB/octave.
観察結果の詳細
There were at least 5 singing males doing dawn song this morning well before sunrise. It was interesting that most of them became quiet after the dawn chorus. The "family" group consisted of what appeared to be 2 adults and 3 juveniles. I am fairly certain that ML167899751 is a young bird that was trying out his syrinx. He produced some very unusual calls and sounds mostly while perched. He then started singing fairly normal songs.
