Parrots in US cities could rival those in native Mexico

April 4, 2016

Mexico’s red-crowned parrots are thriving in cities from Los Angeles to Brownsville, Texas, while in the tropics and subtropics, a third of all parrot species are at risk of going extinct because of habitat loss and the pet trade. Could the city dwellers help save the species from extinction? Read more here.

                                  During the last 200 years, the number of new invasive species has increased worldwide, with more than a third of all first introductions recorded between 1970 and 2014. More new invasions are expected among all groups of species in the near future, with the exception of mammals and fishes. Read the study here.

                                          Boating season is picking up. To protect a body of water from an invasive species transfer, stop by a boat washing station to clean the exterior of your boat, drain all water from ballast tanks, and then dry it to kill any unseen hitchhikers.
