Shared mulberry drool. Waiting for fecal sac.
There's another nest on West End Avenue, higher up. Tolerated because this is a block away from lower nest. Sufficient territorial space.
In went another mulberry. Wait for end result.
"Wasn't that neat?"
Routine- eat, poop, sleep, eat, poop, sleep, stretch, sleep, preen, sleep, eat, poop, sleep, etc.
Just leave mouth open and something will get popped in.
