But what is this?

A few days ago, Son 2 reported that he had noted a flurry of activity around one particular lilac tree.

That is one stoic robin. I wonder why he didn't fly away. Wait a minute, is that a. . .nest?

"I've got my eye on you. Don't you dare come any closer!"
Oh, he's a family man. And by his menacing looks, a really protective Dad.

I just love the color of robin's eggs. They are so dainty and. . .blue.

Don't worry, Mr Robin. I won't bother your babies. But can I chronicle your blessed event?
Please?
