|Amplexis- they "toadly" ignored me as they mated|
"A release call is produced by a male toad or an unreceptive female toad when a male toad or other animal gets on its back and grabs its sides in the position used for mating or amplexus. It's a toad's way of saying "Get off my back! Let go!" It is also used to call attention to a male's territory, and a male amplexing a female will produce the call when another male tries to interfere with the amplexus." californiaherps.com

Much more familiar is the advertisement call. The advertisement call of the eastern American toad is a long musical trill lasting from 6 to 30 seconds. It is a common sound around any body of water in the spring, regardless of size, as the male toad tries to attract females for breeding. It also serves to warn other males that "I am the biggest, baddest guy around so find your own darned pond." They call mostly in the evening and into the night, but may extend it into daytime when desperate. Advertisement call heard here.

Once mounted (amplexus), the male fertilizes the eggs as the female releases them into the water. The result it a rather distinctive set of two spiral strings of eggs generally along the waters edge. Soon the eggs develop into tiny black tadpoles with gold specks, which then lose their tails as legs develop, morphing into toadlets, ready to hit the land.
