Probably about 15 years ago now, by which time House Sparrows had long ceased to be a garden, or even road visitors to the site.
During a Winter month on a typical grey day, I saw a very “tight flock” (almost touching), c30 birds fly straight past my window at head height, they were in total silhouette and there was “no bounce” to the flight!
I’ve never seen the likes of this tight formation, a sort of ellipse in overall shape and all moving so close and without any undulation, before or since!
Would this behaviour be considered unusual for Passer species?
Cheers
