Found an article that led me to an American website, nortbirding.com. interesting id piece on this site.
obviously you have to put the www. bit in them northbirding.com/idtraining
as its an american site and it has american birds on but its something to do on these dark nights
And on that subject at 17.00 tonight it was still lightish, so we are getting there as from today it should get lighter 1min more each night
keep birding

ps I believe Mr Mckerchar spotted a few mistakes with the warbler pictures can you?
