Spring starts early here in the wetlands. The Pacific Tree Frog, or Hyla regilla in scientific latin terms, is already getting ready for the warmer weather to come. As early as January, males begin to call to the females to breed. Pacific Tree frogs have also been called Chorus frogs and when you hear them you know why. They are one of the smallest amphibians around with one of the loudest voices. They have a distincitve, two-part call that is sung in unison to let the females know they are available.
