Well, so far so good. First of all, I understand everyone's concern about not interfering with nature. I believe in leaving baby birds for their parents to care for, but....... (there's always a but!)....... in this case, this little nestling was too young to be out of the nest and I thought that, even if its parents did find it and continue to feed it on the ground, it was too fragile to survive the drop in temperature through the night without the body heat of its siblings. So I've got it in a little box filled with lots of pieces of ripped up kitchen roll, and the box is on top of a hot water bottle. I've been feeding it every half-hour (since 4.30 a.m.!) and I'm glad to say that its feeding well and seems to be a strong little thing. I found this website with lots of good advice on caring for baby birds. I realise that if it does survive its ordeal and gets stronger, it will be totally dependent on me for another two to three weeks. I really hope that it's not too long before we're releasing it back into the wild where it belongs.
