Day #249 Blue-backed Bullfrog

The bullfrogs are the ones now calling for mates. They are the ones with the deep 'garumph' sound, usually coming from swamps and ponds.
This almost robin's egg blue bullfrog was found by me just in time before my lawnmower did when living in Bloomfield beside Brown Creek.
It must be some kind of mutation as I can find no mention of blue frogs in information sources for frogs of North America.
I have heard of the mid-western states finding anomalies in frogs, and so it would seem there are also cases right in our own back yard and most likely caused from pollution of the environment. The neighbours had their lawn - one acre - sprayed every year with pesticides although they both, Mr. & Mrs. C have since died.
Several old homes in Bloomfield back onto the pond, and likely some have old and faultly septic tanks systems and that could contribute as well to pollution of the pond.
The blue bullfrog probably wasn't able to pro-create. Too bad. It's quite pretty, although I only saw one this colour that one time.
