I have a few sit-spots I've been checking out this last month - one is on a forest edge/cliff top near where I know Kingfishers live, in sitting and waiting I've had hummingbirds, warblers, flycatchers, chickadees and nuthatches come by. The other spot is a forest/meadow edge which is busy with cardinals, nuthatches, warblers, and last time a suprise visit of an ovenbird and family of young turkeys who wandered by. I love being able to sit and see which birds happen to come by - my favourite moment is when a wild hummingbird just hovers at face height.
