This here #birb right here is an Effin' Bird Hawk Watcher who is PISSED.
At the hawk, of course, but I didn't know that until after several minutes of a #MississippiKite convention that caught my attention when I walked out the door earlier.

These Kites have 2 different calls: one is a straight 2-note exclamation point typically uttered by fledglings/juveniles, and one where the 2nd note involves vibrato, typically uttered by full grown adults. ALL members of this convention were screaming in the juvenile mode, then occasionally one would do a steep speedy dive then come up mid-tree level. Very odd if this was a sort of fledge ceremony, like graduation, for their young.

It took me til several minutes later to spy a terrified Red-Tailed #Hawk get flushed out of one tree to fly only two trees over for additional cover. Yeah, young and old were ganging up on this one hawk. Def qualifies as a Effin' Bird.
