When a male canyon treefrog wishes to attract a lady, standard protocol involves choosing an appealing spot in the shallows and calling furiously in the hope of being heard over all the other horny males.

Every time bottom frog bleated (their calls rather resemble a sheep), top frog would jump on him and try to silence this competitor. Catalina Mountains, AZ.
