Interesting interaction: the four birds flew together into the top of a cottonwood. They perched together and began a sort of call and response behavior. One bird bobbed while emitting a woody sounding single-note trill. Another responded with a rattle while bobbing more rapidly. These two birds were facing one another as they exchanged these calls. Then a third bird made the flute like two note call but not as frequently as the two who were “conversing” and this bird was facing away from the two. The four stayed together during the exchange, which lasted about a minute before flying off together. Faint recording will be posted soon
