If you're out for a walk this month, and you hear something that sounds like ducks quacking, don't expect to see ducks. The call of a male wood frog fools a lot of people. The all-male frog chorus is revving up now, and wood frog males are the first to announce their availability to females.
When overnight rain arrives in March, male wood frogs emerge from cold leaves and soil to migrate to ancestral vernal pools still encased in ice. Wood frogs and Jefferson salamanders are the earliest amphibians to begin the annual rites of courtship in vernal pools formed by melting snow. The early imperative to breed drives small, chocolate-brown males to pools where they begin broadcasting clucking mating calls that sound like quacking ducks.
