The members of the crow family - to which the jackdaws too belong - are smart birds: they can communicate with each other by eye signals, use available tools for getting food and teach the tricks that they have invented to their comrades. Moving in groups in cities and built-up areas the flocks have their own hierarchy; at feeding the weakest aren’t left to starve but feeding proceeds in order. A pair relationship is “for ever“, unless nature decides otherwise; even in winter jackdaws moving in pairs are often noticed. The noisy birds also cause troubles and irritation but that is another story. The doings of jackdaws are certainly interesting to follow.
