Corvid nests in winter time
When there are no leaves on the trees you may suddenly notice birds’ nests where you did not expect them. Among the most ‘obvious’ are those of our corvid species. They are mostly quite rough structures made from sticks and a bit of mud and mainly found in treetops. Rooks, on the other hand, nest colonially in rookeries, where there can be lots of bulky twig cups in the uppermost branches. Magpies make quite a loose dome of twigs, which may be in the centre of a bush or tree.
