I cannot vote either....I love the sound of the blackbird singing, though its alarm call really winds me up, as at home they can go on and on while I am still trying to sleep. I love to hear skylarks too and try to spot them (usually a tiny dot in the sky as they protect their terretory) I do like the sound of the wood pigeon cooing, it reminds me of summer. I also love to go into the forest near me in may/june time, on an evening and listen to the weird sound of the nightjar. I love the sound that a cettis warbler makes, tiny bird but huge sound. I love to hear cuckoos, the sound of tawny owls hunting, song thrushes in full song, reed warblers calling for mates, starlings can be fun to listen to sometimes, swallows screeching as they fly low across the water and as they fly in formation, the sound of canadian geese flying in V formation, the green woodpecker as it yaffles, the house sparrows going into one outside the bedroom window.......
I could go on and on here, but best of all for me is the nightingale.....I once had the pleasure of waking up in a wood with one singing in the tree above me and I will never forget it, sample it here
