New Study Details Geolocator Tracking of High-Speed Migrants
A new study, published in the February issue of Science, reveals that neotropical migrants such as the Wood Thrush and Purple Martin are capable of traveling at rates far in excess of those previously estimated. According the the new study, "the new geolocators also showed that the wood thrushes [tagged in Pennsylvania] spent between 1 and 4 weeks in the southeastern United States and Yucatan Peninsula before reaching their destination in a relatively small area of Honduras and Nicaragua." The implication is that some species of birds have restricted breeding and wintering ranges, and are particularly susceptible to habitat destruction.

New Audubon Report Shows Shifts in Winter Birds Due to Global Warming
According to a new report from the National Audubon Society, "Nearly 60% of the 305 species found in North America in winter are on the move, shifting their ranges northward by an average of 35 miles. Audubon scientists analyzed 40 years of citizen-science Christmas Bird Count data — and their findings provide new and powerful evidence that global warming is having a serious impact on natural systems. Northward movement was detected among species of every type, including more than 70 percent of highly adaptable forest and feeder birds." Further information about the report is available on the project's website.
