观察细节
The swallows were tending to their nests which are on the underside of the column of the dam. They would circle around and do some close fly-bys so I thought it a good opportunity to make some recordings of their calls. Once I pointed my microphone over the concrete barrier I was leaning on I noticed their behavior shifted subtly. I think they saw the shotgun mic and got concerned. The flock grew and it may even be detectable in the recording that they get a bit louder with more alert calls. I did 3 recordings and put the microphone away. It seemed they settled down a little bit, but they sure did not like seeing that mic.
