Media notes

The first bird in the recording was perched atop a utility pole about 10 meters from me. While recording it, a female flew in and vocalized loudly, and then the the first bird flew east about 50 meters and continued to vocalize.

Observation details

This may have been a family group because they were moving around the neighborhood together and were very vocal the whole time. Three birds persistently followed one male. There were three males and one female, which I determined based on the vocalizations. One of the males made some juvenile sounds an adult calls. Audio recordings. It's also possible that the female was chasing off the first bird in the recording below because it sounds like there was bill snapping by the female. Although there was an interaction between the two birds at the top of the utility pole, I didn't see it well because I wasn't looking through binoculars nor was I using a light.
