Bullfrog 1608-11
If you're going to come along with me to see Mt. Diablo, then your have to see some very special bullfrogs (below) and some very large North American Bullfrogs, Rana catesbeiana, which used to be invasive?
To explain. At Bullfrog Pond, there were basically these one to two pound ! Bullfrogs as well as the Blue and Green below. When the water level dropped to its 2018 level, Great Blue Herons came in and decimated the Great Bullfrog, and they decimated them in less than a week.
But the Blue and Greens were still evidenced at one other pond. However the drought took it's toll on the tiny California Red-legged Toad.
I'll get back to you on the amphibian populations after we've had a decent rain, something that we've not had in 23 years.
Bullfrog Pond, with all its croaking and other mating squeals and noises, was just a magnet for me. California Ground Squirrels nested among the roots of the trees, and were prey to rattlesnakes and herons, but their populations remained.
