Berry Springs Preserve Herps of Texas report, 17Feb2018

At least half a dozen Rio Grande Leopard Frogs were purring and growling (max Call Intensity = 2; i.e., some overlap, but we could still distinguish individuals) when we got down to the fishing pier. Amy said that they had been calling the entire half hour before sunset that she had been there. They took a little bit of a break half an hour after sunset, but they were back up to CI = 2 when we left an hour after sunset. We didn't see or hear any other amphibians that night. However, when we arrived, we did get to see a nice Great Blue Heron at the top of a bare tree by the creek silhouetted by the setting sun.
The monitoring period was 18:20 - 19:20.
Participants were Kathy, Amy & Mike, Christie, and Diane.
Environmental conditions at the main pond half an hour after sunset (I was so excited to hear the Rio Grande Leopard Frogs when we arrived, I started recording right away instead of first collecting the environmental data):

  • Air temperature = 53.8 deg F
  • Water temperature = 63 deg F
  • Sky = Mostly cloudy
  • Water level = Average
  • Relative humidity at sunset = 60 %
