Birdy calligraphics

I'm trying to develop a lightning quick drawing hand and eye---it's one of my art goals for 2010. To that end, I've been (loosely) following the precepts in David Rankin's Fast Sketching Techniques, and have applied them in these sketches of birds outside my windows. I was so taken with Kate's recent squirrel sketches that I wanted to add some of our local crew, haranguers at the bird feeder, to my own repertoire. Ahem. When you WANT squirrels to come to the bird feeder, do they come? No, they do not. Don't want them and they'll be there like wicked fairies at a christening.
