Looks like I have ducks on the brain! Here's the birthday card I made for my dad. It just so happens to use some of the same kinds of ducks as the National Post piece I recently illustrated (here's a link to the sketches, on Monday I'll post the final). Left to right: Ruddy Duck, Hooded Merganser, Horned Grebe, and Mallard.
My parents have become enthusiastic birders these past couple of years, so I know that March and April are major birdwatching months. A lot of migratory birds return to Canada in the Spring so it's an exciting time to be out with binoculars and a scope!
