Depending on your latitude (how far north or south you live), you may spot young painted turtles emerging from nests sometime between late May and mid-June. These turtles have been overwintering underground where they may have even been partially frozen! As turtles emerge from their nests, they will likely head for the closest body of [...]

Beginning in mid-April whales begin to arrive in the Gulf of Maine, many with newborn calves, to feast on plentiful sand eels, copepods, plankton and fish. Familiar visitors to Maine’s cold waters include humpback whales (whose Latin name, Megaptera novaeangliae, means “Big-winged New Englander”), pilot whales, minkes and massive finback whales, which can grow to [...]

Are you unknowingly harboring tiny hitch-hikers? One of the ways pests, diseases and harmful weeds spread is by hitching a ride with humans, pets and vehicles. An invasive pest is one that is introduced to areas that are not part of its natural range, where it may not have any natural enemies to keep its [...]

Birds are on the move!  Migratory birds are traveling from their wintering grounds in Mexico, Central and South America to the U.S. and Canada, where they feast on abundant insects and plant foods during spring and summer.  How do they know when to leave and where to go? Birds that migrate short distances – such [...]

Invasive species – those that are not native to a specific region – often grow fast, spread easily and displace native species. Invasives come in many shapes and sizes, negatively impacting wildlife diversity and the health of an ecosystem. Invasive weeds can reduce crop yield and compete with native forage plants in pastures, reducing food [...]

New research shows that estuaries are vital for salmon survival. Pacific salmon species—Chinook, Coho, sockeye, pink and chum, in particular—use intertidal marsh areas in estuaries as transition zones to acclimatize from fresh to salt water and back again as they complete their life cycles. Among the findings: marsh habitats are consistently used by juvenile Chinook [...]

Is the lower Hudson River really a river…or is it an estuary? The answer is both. In spring, rains and snow melt often force fresh water down the Hudson turning the tidal watercourse into an almost purely freshwater river. But by summer, salt water can push its way up the Hudson River more than 70 [...]

Animals like frogs and turtles are waiting out winter by submerging or freezing. As spring temperatures rise and their prey becomes active, reptiles and amphibians will make use of small pools of melt water called vernal ponds. These temporary pools are the breeding grounds and also the feeding grounds for many animals. As the spring [...]

The 2012 Great Backyard Bird Count (GBBC) takes place from Friday, February 17 through Monday, February 22. Each year, volunteers across the country tally the birds they see in backyards, parks and natural areas. Last year, GBBC participants racked up more than 11 million observations and identified 596 species! Counting birds during GBBC helps scientists [...]
