I borrowed these frog eggs from a pond behind my house. Not the big pond but a much smaller pond nearby. Every spring, or least since I've live here, we've found frog eggs in the pond. This year there were about the same number of masses as usual, but each mass was smaller. In the past, there were hundreds of eggs per mass and now, as you can see, the number is much smaller. Yep, that is an entire mass in the picture ~ about 30-40 eggs.
I will hatch these babies and keep you informed. Before they get their back legs I will return them to their home pond and hopefully listen to their mating song next spring.
