Pika (Ochotona princeps)
This Pika was about 30 feet away. The ridge he was on was too
steep to get closer.
I used 800 mm, but since he's only 3-4 inches big, he still looked small.
The real closeup images are digitally cropped and not sharp. There is a really cute video link at the bottom of the page.
