Description

A scene in one of the 'vernal pools' that form each spring in the ruts of the soggy dirt road between the creek and the water treatment pond here. They always fill with pollywogs in the weeks of their existence.

I suppose these are Sierran Treefrogs...

Clearly, it's the larvae that do the damage to the Dock.

A pair of these cruised leisurely into a flock of Tree Swallows briefly, and then flew away... This one had some sort of short interaction with one of the swallows before leaving.

I believe I've seen these consistently over the last year in this spot without ever being able to get a picture or even a good look. Usually they seem to be approaching the large water treatment pond, gliding in at around 50' elevation. I wonder whether anyone could hazard a guess.

Picked up six of these wandering in the grassy verge of the creek trail. They made no attempt to bite in the hour I carried them; but crawled restlessly over my body until I plucked them off. My dog got three-- that I could find.

All of these were male.

Hundreds circling the pump house on this water treatment pond; individuals periodically darting under the eaves where I presume they are nesting.

Someone has 'decorated' this structure with dangling/waving mylar strips... is that an expedient to discourage these birds?

Saw a few of these on the curly dock; the plants involved were all a bit chewed up.

The first two were a puzzle: I assume the first one is hugely gravid? And if so, what's the second up to at this late date?

Apparently harvesting mosquito larvae from one of the 'vernal pools' that form in the ruts of this dirt road from spring rains.

When I startled it, it simply 'skated' out onto it's little pond; and soon scrambled back onto the partially submerged leaf where it had been perched.

From our work crew, removing thistles as time runs out before they all bolt to flower.

This individual, by common consent, was the mother of all milk thistle.
