Well, the subject didn't fly away - that's good! The photograph gave me time to observe details about the bird I probably wouldn't have noticed in the field. In the field, birds are tiny, quick and tend to hide behind branches, leaves and in the underbrush, making observation difficult. I didn't use watercolor for this first sketch (computer is upstairs, drawing equipment is downstairs). I will print out the warbler picture to work on for my next sketch. I think that next time, I will try to compose the picture better.
