Researchers from the University of British Columbia and Cornell University compared two methods–analysis in the lab and experiments in the field–for 72 pairs of related but geographically separated bird populations in Costa Rica, Panama, and Ecuador.  The new study shows that pairs of birds that failed to recognize each other are currently categorized as members of the same species, suggesting that current taxonomy does not reflect actual bird behavior when it comes to song.  The researchers propose that 21 such pairs should be recognized as separate species based on song discrimination and that playback experiments should be the standard forRead More

Amateur Observations Help Predict Vast Bird Migrations 

With puzzling variability, vast numbers of Pine siskins from Canada’s boreal forests migrate hundreds or thousands of miles south from their usual winter range,  suddenly appearing thousands of kilometers away from their normal habitat for a season, before disappearing again for several years These so-called irruptions were first noticed by birdwatchers decades ago, but the driving factors have never been fully explained. ow, a collaboration between zoologists, climatologists and amateur observers has explained the phenomenon, and possibly given us the tools to predict where they will turn up in the future. The findings could prove important to our understanding of the effectsRead More
