Frog and Toad Survey #2

On Friday night a sibling and I along with her husband went on the second frog and toad survey.  We started about sunset or 9 p.m. and finished at 10:41 p.m.  Rain feel lightly at a couple spots. We saw lightning and much later heard thunder but none of the storms were close.  The air was warm and humid. We heard six species of frogs; spring peepers (photo), chorus frogs, gray tree frogs, American toads, wood frog and green frog.  The water levels were high and at one stop water lapped at both sides of the road.  The lightening bugs were out.  At one stop we found a larva with it's rear end glowing in the dark.  Thank god for small favors, I may have problems but at least my a$$ doesn't glow in the dark.  At the stop where we smelled a skunk and heard a crazy loon chorus on the first survey, this time we heard a hissing in the reeds not too far away from the road.  What kind of animal would hiss at us after we were standing there for four minutes?  A skunk?  A goose?  Everything gets a little spooky when you're standing on a deserted road in the dark listening for sounds.  I keep telling myself swamp monsters aren't real. Swamp monsters aren't real.  Swamp monsters aren't real.  And swamp monsters probably would not hiss.  If anything, a swamp monster would moan.  If I ever hear a moan out there on a frog and toad survey, I'm getting in the car and locking the doors.
