The ponds of spring and early summer are alive with insects, amphibians and reptiles. Here are a few from yesterday’s pond survey.
As the weather warms, California red-legged frogs are more visible. This frog is a sub-adult.
The California red-legged frog is listed by the United States Fish and Wildlife Service and is classified as Threatened. http://ecos.fws.gov/speciesProfile/profile/speciesProfile.action?spcode=D02D
Each pond has tadpoles, sometimes just tree frog and other times tadpoles of red-legged frog, western toad and tree-frogs.
Tree-frog tadpoles were present in every pond.
The California tiger salamander larvae we found were approaching about half the size of mature tiger salamanders. Their gills are apparent.
This cts larvae is not quite half the adult size. All California tiger salamanders are listed as either Threatened or Endangered. http://ecos.fws.gov/speciesProfile/profile/speciesProfile.action?spcode=D01T
A garter snake sunned itself on a floating log.
This is a Pacific newt larvae that overwintered in the pond.
The ponds contained many dragonfly nymphs. At one pond a “squadron” on red dragonflies gave me a photo opportunity.
These red dragonflies appeared to be reproduction mode.

Searched for California tiger salamanders in the middle of the night last weekend. Took my daughter Betsy along for company. Her question, “Does it make you nervous walking around in the dark at night?”
My answer, “No, except when I don’t know where I am.”
Darkness is a fun adventure when you’re in you comfort zone. The more time you spend out at night, the more you can enjoy the medium. And, you can find more critters in the dark.
We didn’t find the salamanders, but we found a couple western toads and a few California red-legged frogs. One pair was in amplexus, a scientist’s word for mating.
Toads will soon be laying eggs in the nearby ponds.
