a Blue Tit ringed as a nestling in a box in Roeburndale near Wray this year has been caught twice in my garden in Lancaster. If it moved through Littledale, this will have moved about 14Km (a crossing directly over Clougha seems unlikely). One of the old papers on Blue Tits said that they would not cross open ground the size of a football pitch - this one clearly hasn't read the script!
This isn't the first of our Blue Tits to make this type of journey, but it does show that urban gardens hold birds (even sedentary ones) from a surprisingly wide radius
