gathering in the trees begins just about when dark falls in November

I’m not sure I sincerely love Jackdaws as such like they are little irritating, obnoxious, throwing leaves around while looking something to eat, little naturally nervous kinds, almost invisible in urban city if they didn’t have their voice and their gathering.
They make beautiful constellations in the air as black units of sound, speeding sound, speeding entity as do city pigeons. Black the blackest against the sky until they settle together on branches, or maybe whirl one time around their home tree because one of them thought it might be a good idea or got scared and every bird followed. Every Jackdaw with recognizable Jackdaw noise similar to factory-like voice of a bird robot, making one big bird out of hundreds.
