I've noticed recently that birds are now singing throughout the night. Several posters on the Yahoo message boards report the same (there are a few at this thread: http://uk.messages.news.yahoo.com/Climate/threadview?bn=UK-NEWS-CLI-Global+Warming&tid=3035&mid=3035&tof=1&m=tm&rt=2 ), but no one has provided an explanation yet.
I know that artificial lighting can cause birds to sing when they'd normally sleep. We have a street lamp at the back of our garden, but until the last few months (and unusally warm winter weather) this didn't seem to disturb the birds. I've also heard the same nocturnal singing in other areas around the English North West.
Can any ecologists/zoologists/learned enthusiasts out there shed some light on this for me?
