When I was about nine my brother(older)and I were walking in the local park (in the Fenced off bit where there was the 'dangerous' empty(bomb damaged) open air swimming pool0.we noticed a couple of crows doing a Dive bomber routine at the deep end of the dried up pool,so we went to investigate and found a tabby cat stalking a fully fledged but non flying young crow.The parent crows were doing a pretty good job of keeping puss from a nice big dinner,but obviously were on a hiding to nothing.We therefore gathered up the crow and took him home,to our parents great delight.And the neighbours when the parents discovered that junior was only in the next street to the park.It took three days for them to get the sprog crow out of Dads redundant Rabbit run and up into the trees at the end of the garden and then across to the park.Three crows can make a fair amount of noise in those circumstances.We were not the most popular kids in the street for a while
