A short list of critters which are out or newly arrived and I can hear from my front porch:
Spring Peeper, Pseudacris crucifer, are breeding in the pond.
American Toad, Bufo americanus, are also breeding in the pond.
Silver-Haired Bat, Lasionycteris noctivagans, are flying around our kitchen for no good reason. Okay, only one bat. I named him Sparky. He is gone now.
Damn mosquitos. Got my first bite of the year while looking for bat escape routes.
