觀察細節

Juvenile calling to adult. Could sometimes here another return call. Pictures. Identified by Jonah Benningfield on Sept 23, 2021 Both audio recordings are the same recording (Voice Record on iPhone 8), but the 2nd one processed in Audacity with noise reduction filter. 1st one was processed in Ocenaudio, which has more simplified controls. Male and female adults also present. Photos of male only. Feeding around the source reservoir for the waterfall at the top of the hill. Nice suprise, nicer still to find out the unidentified bird was the fedgling.
