It's obviously nesting time. Yesterday, before I left the school I work at, I saw a number of children, with a teacher, taking turns clambering on a stool, to peep into a box around the electricity meter. I asked what was the excitement and I was told that it was the nest of a magpie robin with 3 lil ones in it! So I went to have a look too. I'm glad I did, because neither the young teacher, nor any of the 4th grade children there, knew that one should never touch the babies.
Anyway, while everyone was having a look, the poor parents flew around frantically, making little chirping noises. Then one of the kids noticed that there was feed for the babies in the parents' beak. So we all quickly cleared out from there, to leave them in peace. Completely slipped my mind that I could have taken photographs with my camera!!
