    Thanks for the messages -- what Dan (and Murray) wrote makes sense. It won't be guides leading tours, but I do hope that more people (whether academics or not; such projects are often appropriate for sharp students as well) will conduct playback experiments along these lines. Jurek -- you...

    Thanks Peter and Dan for your messages -- Peter - Thanks for the links to the HBW vocal analyses you compiled. They are interesting to read. They do fall short of what would be necessary to convince a skeptic. I agree that ideally, playback experiments (to examine behavioral response) would be...

    Species recognition between geographically isolated populations

    Andy Kratter said it perfectly -- Genetic data is of utmost importance when trying to determine whether species that are sympatric are reproductively isolated. Want to know how many species of Scytalopus there are in an Andean cloud forest? Then go out, sample thoroughly, sequence and see how...
