Mixed news: I discovered that both parents are hard at work. So this bird....
Though the lower one looks bigger and fluffier than the one above it (with a worm in its beak), they're very difficult to tell apart. The fluffiness is due to the fact that it's sitting.
The other bit of (maybe not so good) news is that there is one unhatched egg in the nest. It seems to get moved around so it's not visible when I took the photos.
So what else is there to tell? I didn't know how to tell a song thrush from a mistle thrush but I noticed white colouring at the end of the tail feathers as one flew off. This, I've just learned is a indication that it's a mistle thrush. Also where I wrote the ''unmistakeable rattle of an angry magpie,'' I may have been mistaken because ''A diagnostic dry rattle, akin to that
made by old-fashioned football rattles'' is also characteristic of the mistle thrush. In my defence, I did say I'm not an expert!
Update 5 May
The three chicks appear to be doing well. The unhatched egg is either hidden from view at the bottom of the nest or it's been jettisoned. It's a bit blurry but I managed to capture an early bit of wing stretching this evening.
Bank Holiday family reunion!
After a very stormy night I awoke this morning (10 May) to find that there were only 2 fledglings left in the nest. At first I was worried that the wind had carried one away but then realised that the remaining two were ready to leave.
