What birds do when we aren't looking

Update: signed prints are now available of the bird with the balloon.

This started out as one drawing, and soon became a little series. I created the fake book cover for fun, which liberated me from having to write "what birds do when..." on each drawing.

I like the quietness of black and white, and I was really aiming to make this series quiet and understated. It also means I don't have to fuss over the colour schemes of various birds :)

I can't seem to part with the original drawings, so they're not for sale. But I'm thinking of making more of these birds doing non-bird things, and putting them together in a little book. Do you think anybody would be into something like that?
