Spot the crows' nests

Soon, as the leaves burgeon and thicken, the masses in these trees will be invisible, but for now, which of these trees is infested with miseltoe and which is infested, well perhaps populated, with crows nests? I wonder if the crowsnest on sailing ships was so named to due to the fact that these large black birds always nest high up - one wonders if they have toe ropes in the nests to avoid being blown out.
