Here's a more cheerful update.

It's cold today...

Well good morning.

Yesterday was their last day of nesting, now the little ones are out in the world. Good luck to them.

Spot the visitor.

Same nest, second hatching in progress.

Update: second breed now hatched out.
Pic later.

Here they are.

I think it's four of them this time (difficult to tell in this pile), but I don't want to outstay my welcome just to arrive at a definitve count

For those keeping up: it's actually five little blackbirds, but number five is always hidden from view, nest is tightly packed.
In the last pic from a couple days ago they are neatly organized in a circle, and you can identify all five.

Feeding of the five feathered is happening at a normal rate. Meaning fast. Parent birds are flying in and out at two minute intervals right now while I enjoy my coffee watching the proceedings.
