long tailed tit

bottle tit as it's sometimes referred to due to the bottle type nests they build,so tight in fact that the adults have to fold their tails over the back to enter. beautiful wee birds i watched them for about twenty minutes unfortunately this is the best shot i could get. playing about with the bigger lens ,heavy, i took a long walk up the river almond beautiful it was too. think i also saw a yellow wagtail, either that or a grey one in winter plumage, very confusing. really enjoyed the time on my own with the dog and the camera, does life get any better?
