It's hardly a secret that I've had a bit of a thing going for frogs and toads - anurans - during the latter part of 2007 (the anuran series has so far consisted of part I, part II, part III, part IV, part V, part VI, and part VII). While the whole exercise was a good excuse to learn a lot about…
Last year was Year of the Frog (nothing to do with the Chinese calendar, but instead a global effort to raise awareness about the plight of the world's declining amphibian species). I hope that you've not forgotten that the global effort to slow amphibian extinction continues unabated. For various…
South America has a diverse and well-studied toad fauna. The continent's toads include some decidedly untoad-like taxa, such as the brightly coloured stubfoot toads or harlequin frogs. These remarkable little animals are superficially similar to the better known poison-dart frogs. What makes South…
I forget how it started now, but lately I've been very, very interested in toads (yes, toads), so much so that I've felt compelled to write about them. The problem is that toads - properly called bufonids - are not a small group. On the contrary, this is a huge clade, distributed worldwide and…

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.
