And then there were four

Blipped these fellas last week (see here), but could only make out three any time I had a keek at the nest. (I can't resist the wee fluffy things, sitting there like bookends, running the parent birds ragged.)

Now they're filling out, the fourth one has come in to view.

I know they'll be migrating soon - hopefully some will come back and use the nest again next year.

Update, Friday 9th Sep. Came home tonight and the birds have indeed fledged - empty nest!
