While we were poking about yesterday I came across two separate piles of remains in the leaf litter. Both were adjacent to the water's edge and both appeared to be from the same type of animal. Both were also relatively fresh. Hmm...our guess is frog eggs. The parts looked right and smelled right (yes, we smelled 'em -- it's what we do)and were in likely areas. No wonder the frogs were so hard to sneak up on - they were wary of becoming dinner.
Our only question was why weren't the eggs eaten? There was no evidence of any other organs or body parts, just the ovaries and ducts. Best guess is the eggs are from southern leopard frogs and to our knowledge they are not poisonous - they certainly get eaten after being laid. So why were these left behind? Anybody know?
