Birth control for Bremen’s cats

As spring days are punctuated with the chirps and trills of bird song, a recent article in the Guardian seems especially timely.  The northern German city of Bremen plans to take action to curtail its burgeoning population of free–roaming cats, estimated to be at least 1,000 strong. Whether feral or domestic—cats take a significant toll on birds and many other small wild animals.  A U.S. Fish & Wildlife fact sheet on bird...

Immersed in the clouds: Interview with tropical cloud forest researcher

There is a world within the canopy of a tropical cloud forest that not many people get to see. In this unique ecosystem—maintained by the exceptionally wet microclimate of cloud cover—orchids, moss, lichens and other epiphytes grow in every crease and pocket of the supporting tree branches. Here, hundreds of species of birds, along with monkeys and other mammals navigate the aerial landscape, scattering seeds along the way (see below...

Zebra finches practice singing for the ladies

The male zebra finch (Taeniopygia guttata) learns to sing in private before performing for a female audience, according to Satoshi Kojima and Allison J. Doupe from the University of California, San Francisco. In addition, juvenile male finches seem to step up the quality of their singing, despite their immaturity, when in the presence of potential mates. As described in the blog Talking Science, part of National Public Radio’s Science...

Rest stops for fall migration

Many animals migrate in the fall to exotic locales and warmer, more abundant southern climates. Among the more famous migrating winged species are monarch butterflies, but there are several species of birds that also migrate during the fall. Some of these birds, such as hawks, rest and “refuel” in the Gulf region of the United States as they traverse southward.
