Fernandez Spring



Fernandez Spring was a clear shallow pool in the shade of a spreading valley oak. It was the only spring where I could set the camera for 24 hr shooting while I was in San Luis Obispo County. The reason is that passive infra-red sensors are easily tricked by puffs of warm air, moving vegetation, and dappled sunlight. The resulting false triggers can rapidly fill a memory stick with an exhaustive record of passing shadows. I didn't have to worry about that here at this shady spring.

The spring was about 50 yards from the water trough mentioned in the previous post, but it was a far more popular stop for thirsty animals. Here the camera's batteries lasted for 24 days, and 231 of 310 photos were of animals (a success rate of 75%). I could identify 16 species, but 2 additional birds remain a mystery.

A bobcat visited the site twice and both times it lingered. On this visit I got 6 pictures of it looking rather bored. It stayed for 34 minutes, probably waiting for birds.



It was too late. A covey of 22 half grown valley quail (and a flash-lit moth) had passed through 40 minutes earlier.



The spring was probably a productive hunting ground for the cat. Twelve species of birds visited to drink and bathe, including a Cooper's hawk.



One night a screech owl flew in for a bath a half hour before midnight.



The raccoon dabbled in the spring for a minute and half before going to the water trough.

The owl and the pussy cats



I set the cam at this mossy rock at a creek crossing on Dec. 6. Nothing happened there at all until Dec 20 when the gray fox showed up for two pics. The pumas came on Dec 22nd and 23rd. I got two pictures of them each day. These are the same two cats I photographed 18 days earlier sitting on the road below our house (see "No poodles tonight"). You can still see vague spots from the cub's neonatal coat, and from the size of its feet I would guess that its a male.

But let's not ignore the screech owl (or is it saw whet owl), who made its appearance the day after Christmas. When our windows are open in the summer we listen to this fellow's serenade, but so far he hasn't moved in to either of two nest boxes I hung in the woods.
