Thanks Oxon. I have turned it on and shall leave it all day, unless I find myself wasting too much time! It is good to see some healthy chicks after my distressing few days. On Saturday evening I saw and heard a great spotted woodpecker taken by a sparrowhawk from my garden. I had been watching the nest so hoped there was another parent, but no, so I had to hear the pitiful cries from a completely inaccessible dead branch 60 ft up. I am still hearing an occasional cheep, but the single baby is no longer looking out of the hole. What a horrible way to die for Mum and chick. That is nature unfortunately!
Oh shysal....I can imagine how you'll be feeling. It's how it goes, though, and the sparrowhawk had to feed its young too. We have blue-tits nesting in a box high up on a pole in the garden. DH put the box up really high so that cats couldn't reach it. The parents are in an out of the box at a terrific rate, feeding the cheeping babies, and all I have to worry about now, is that they are not picked off by the cat as they leave their nest. If I'm around at the time, I'll keep the cat in, for sure.
