Last year I had drama with a bee's nest in my ground that got half dug up by foxes and then overtaken by a Cuckoo bee, I found the queen crawling away with her wings bitten off and the resulting nest died out a few weeks later since Cuckoo bees don't continue the nest. (I would upload a picture of her, but file is too big)
I also witnessed a bird of prey land in my middle garden and fly off like a shot at the sight of me, leaving only a few sparrow feathers behind from his latest meal!
This year I am proud to announce a nesting pair of Blackbirds in my ivy, right over my kitchen window! Already, I have observed the female bird doing all the nest building, although the male stood guard and even brought her the gift of a worm today.
I must say, one of the delights of being a gardener is the adventure with wildlife!
