I’m not sure if this happens everywhere – I suppose it does, if this species of bird is indigenous to the area you live in…or maybe birds do this everywhere and I’ve just never captured it until now.
It’s a single thought – One bird (who knows which one) seems to be making a decision for the entire flock to fly in a particular direction and they all go as one. Great masses of these birds will black out the sky – all flying in the same zig-zag patterns like they’re performing some sort of new Olympic sport. It’s spell binding to watch.
I wonder if humans act this way and we don’t even know it. From above, I can only imagine this is what we look like as we traverse from home to work through busy city centres. Only, we stop for a 7$ coffee along the way.
