Amazing…your right about Blackcaps…not many stay for winter…the only time i ever saw a blackcap was when i was driving fast upa country lane and then suddenly something hit my window and i then i braked…i checked in the wing mirror and saw that something was moving on the ground in fact spinning..i got out and saw it was a bird and picked it up and to my horror it was a male blackcap…it was the first time i have seen a blackcap and it was almost half dead…i picked it up and realise it could not stand or keep its eyes open…i was really sad…it slowly began to wake up…and i began to try and stretch its wings …it hopped from my hand onto my shoulder…it did not want to leave me…i let it perch on a branch…still seemed a bit sleepy…eventually i think it flew off…
will try to uploads pics in fact here it is
