Here are some recent sketches from the Vermont Institute of Natural Science (VINS) in Quechee. It’s a wonderful place to draw raptors from life, lots of cooperative models. They are all rehab injured or otherwise un-releasable birds and are well taken care of in this beautiful facility. You’ll notice from the sketches that the resting birds are easiest to capture on paper. Owls have great shapes to draw, although it’s always tricky to figure out what’s going on under all those feathers.
VINS is well worth a visit if you’re in the area, just off Rt. 4 on the way to Woodstock in Vermont.
