Florida has been an ecological trainwreck ever since the illegal pet trade introduced Burmese pythons into the environment. Don't worry about it though; it'll all end entirely once we humans keep extending in the state and overrun the animals' natural habitats.
What birds besides geese like to eat these large tasty morsels known as mosquitoes?
I dunno. But on the other hand, they seem to be a favorite with bullfrogs. At least my pet bullfrog loves them--then again, he'll eat anything that can fit into his mouth 
Sounds like a bullfrog. You don't want to even put two bullfrogs in the same aquarium. If there's a size difference between the two, you'll very soon have only one, with the smaller one inside the larger. Bullfrogs are known cannibals. Hell! A bullfrog will even eat a mouse or a duckling if he can catch one.
Yes, and science teachers know this fact. That is why they order extra and still come up short, so that students need to share a bullfrog.
They will eat a mouse or a duckling? Wow! Mice can be fast,
Bullfrogs can be even faster. They stalk their prey and strike with an amazingly quick, strong jump. I've seen videos of a bullfrog jumping several feet into the air to snag a bird from a low hanging branch.
I was wondering about this. Now it is well known that feeding lizards certain insects can be dangerous to the lizard, as certain beetle larvae can eat their way out as the lizard will often swallow their prey whole.
The frog also swallows his prey whole, so if he were to swallow a mouse or rat, then that mouse or rat could gnaw away at the frog's insides and escape leaving the frog to die a slow death. That would be the last time a certain frog would try that trick.
Birds have nasty beaks. I can only imagine the damage that beak could inflict.
Now mosquitoes are another matter. Unless this particular mosquito is blessed with a dagger for a mouthpiece, they do not have deadly appendages that could inflict a mortal wound inside the belly of a frog, lizard, fish, or bird.
