These pictures were taken in early April and in early May (the damned scheduling) there will be a series of videos on my YouTube channel of this very bedraggled looking Bobbit.

When I took these, I had seen him flying about with food in his beak, and feeding Tiny (or at least I am pretty sure it was Bobbit and Tiny not some other loved-up pair of robins).
I can't work out what exactly is going on as I also see Tiny.

Yes, that is Tiny. So I guess she can't be incubating.
Bobbit seems very keen to see me when I am in the garden, and flies over repeatedly, though not for long. Occasionally he gives me a little burst of quiet song. I don't know what my presence means to him as he takes suet himself out of the window feeder, which is never empty, so I am not a useful source of food. Besides, and David Lack in The Life of the Robin mentions this, the birds choose primarily grubs and worms and only occasionally the "junk food" we supply, particularly for babies, who need the complex nutrients of natural food. Yes, they are better parents than we are.
So what's all this attention about?

I wonder if he's missing the carefree days of his youth - you can see links to videos of a very fresh-faced Bobbit below. Maybe he feels a responsibility to our relationship? Maybe he just likes me?

He also does regular fly-bys, whisking past my face before landing and looking. I cannot fail to notice him. And, if he's next door, most times when I call "Bobby!" he flies to my fence.
David Lack writes that there is a mystery: the life and mind of a robin is so different from ours that we simply cannot know what the bird is experiencing. I agree in large part. But I do believe that we can share the experience of a connection.
Interesting to read about David Lack at the link. And that robins prefer grubs and worms. Do robins moult like many other birds, such as crows, do? And yes, I'm guessing Bobbit likes you 😍
