Singing?
Such as a crow can manage, a squonking Albert Ayler exhuberance, a
raucous James Brown shout, Cab Calloway exhorting the gang perched
below on the tips of the trees to join him and then they swirl around
as dog fighters, like leaves in a whirlwind, not going anywhere but
round and around then back to the treetops, heads bobbing and jerking
as they gossip and yell:
"Did you see that Jack - what was he thinking,
landing on that squirrel carcass just in front of that dark green
beast with the human inside! Har har- boy, did he get a scare! Har
har!"
