Often, as my Mom taught me, the best way to observe nature is just to sit in the woods or meadows silently and inconspicuously for an hour or two. Things will happen. A Box Turtle will wobble past. An upwind fawn will walk ten feet from you. A Redtail will dive on a mouse. A Blacksnake will slither over your warm Wellies. Dragonflies and butterflies will perch on your hat. A Marsh Hawk will pass just over your head, startling you.
A lot of quiet outdoor sitting takes place on deer stands, in duck blinds, etc.
Yesterday, I watched from my office window, a Sharpie attacking sparrows 5 or 10 feet from my window. That's not unusual. What I had never seen before was the frustrated Sharpie just settle on the ground and to begin stalking the sparrows on foot through the hollies where they had fled for safety. He walked with a long slow stride, very alert, just like a Velociraptor.
Have you ever seen that?
After a few minutes of stalking, he somehow flushed a flock of about ten sparrows from a holly and tore off after one. I couldn't see whether he was successful. Wish I had taken a photo.
