観察結果の詳細
The first recording has the contact call, a series of 2-7 calls in very quick succession. Notably, that call is pitched, meaning some frequencies are notably stronger than others (unlike something like a common yellowthroat call that hits all frequencies equally). But the nuttall’s call hits the frequencies just below 4K, 8k, and 12k the strongest. The second recording has drumming at 2sec, 5sec, 9sec and 12sec. It has 20-30 even strikes lasting about 1 second in duration. There are also a few contact calls in that recording. The third recording starts with a light tapping, which is a nuttall’s probing a tree. There are some contact calls in the middle of the recording. Then it calls back to the light tapping.
