We're experiencing what, on the surface anyways, appears to be an excellent bullfrog year. There are thousands of large, legged BF tadpoles, and the adults are here in numbers that I haven't seen in years. I expect the herons to arrive in force, any day.
Tony,
Same here in Northern Indiana, but not just bullfrogs.
Haven't had many visits by herons this year. When I do I just fire a bottle rocket toward them.
