Comings and Goings

Two Harris's antelope squirrels look out from their rocky perch along the Vaquero Trail in the Brown's Ranch section of McDowell Sonoran Preserve in Scottsdale, Arizona

I first learned of the Harris’s antelope squirrel from a sign on the Bajada Nature Trail a couple of weeks after we moved here, and funnily enough got my first brief look at one just a few minutes later. After seeing one of the little ground squirrels up close on the Vaquero Trail I did a little research to learn if their home range was small (it is) and if they liked to look out from higher vantage points like the one I had observed (they do).

Knowing that, I decided to hike the Vaquero Trail again and kept my eyes peeled when I approached the area of my previous sighting. And there it was up on the rocks! Up on a small hill it had a complete view of its surroundings and would have seen me before I saw it. Unfortunately I had forgotten my 100-400mm lens at home but I returned the next morning and there it was again! I had settled on using my Canon 100-400mm lens with a 1.4X teleconverter as my wildlife hiking setup, which presented a problem, as on my Canon body I could only use the center focus point, and the autofocus wasn’t that reliable in low light. Attached to my Sony body the autofocus was sometimes quick but not reliably, but I could also use it for video and for manual focus.

I shot the squirrel with both setups, starting with the Canon before switching to the Sony. Fortunately the AF was working well when a second squirrel popped up behind the first! The experience cinched a decision I had been mulling for a while now and that afternoon my wife and I went down to Tempe Camera and purchased the Sony 100-400mm lens and Sony 1.4X teleconverter. The new lens proved its mettle as soon as I arrived at the preserve the next morning, and on multiple hikes since, but those are stories for another day.
