GrrlScientist is an evolutionary biologist, ornithologist, aviculturist, birder and freelance science and nature writer. A native of the Pacific Northwest, she relocated from Seattle to NYC with her parrots after earning a BS in Microbiology (emphasis in Virology) and PhD in Zoology (Ornithology) from the University of Washington. In NYC, she was the Chapman Postdoctoral Fellow at the American Museum of Natural History for two years, pursuing part of her "dream" research project by reconstructing a molecular phylogeny of the parrots of the South Pacific islands. GrrlScientist and her five parrots are currently relocating to Germany, where she will continue writing her blog while also writing a book and learning German. (Meanwhile, her parrots will continue to nibble on her extensive personal library.)

My local froggie pool: http://drop.io/dt3vubi (audio mp3 file)
If you load it into an audio recording program such as Audacity (free) and look at the waveform, you'll see that frog calls decrease notably in the center where there is an overflying airplane. I heard that one of the dynamics of communal calling is a protection against predators, who can not get a good fix on individual frogs because of the chorus. I would venture that predation increases during lulls such as the one in this recording. It would be interesting to see if anybody has done/can do a proper study of this effect.
