Fall migration has wrapped up for all but a few bird species. This semi-annual rite of passage typically follows predictable timetables and geographic routes. Exceptions to the rule, "irruptive" species, are northerners that head this way certain winters, driven out of their home territories by food scarcity.
October 18 is the Full Hunter's Moon, and heading south now are hunters of a different sort: turkey vultures, scavengers that feed on carrion.
Unlike other birds, this species has a uniquely developed sense of smell that guides them to their next meal. Weak fliers, turkey vultures are skilled at hitching rides on air currents. Rarely flapping, they hold their wings in a V angle and wobble a bit while gliding. Because of their large size, they're often misidentified as eagles, but eagles power along, strong and steady in flight, never tipsy.
Since June New Hampshire lawmakers have been grappling with what to do about the persistently above market cost of electricity at the state’s largest utility, Public Service of New Hampshire. Now the legislative committee wants advice from regulators to see if selling PSNH’s power plants is the solution, but that advice may be slow in coming.
A lot of people are asking this question, concerned at the diminished numbers of this most charismatic butterfly. Not many schoolchildren this fall will be able to watch caterpillar transform into chrysalis and then glorious adult—metamorphosis in action.
Monarchs are celebrated for their fall migration to Mexico, but the population that spends the wintering there is experiencing a decline. In fact, this past winter it was the lowest on record.
Reverse migration: African American populations boomerang back below the Mason-Dixon line. Plus, why adding "sandwich board" to your resume could be a good thing. Also, an NGO spreading sustainability in Niger turns 10. And a look at a Native American Art exhibition from the Hood at Dartmouth. Finally, data through light - the future of electronic transfer?
Analysis of 2011 U.S. census data continues to reveal surprising demographic shifts…including a largely unreported exodus of middle class African Americans to cities in the south. Today, 57% percent of black Americans live below the Mason-Dixon line, the highest percentage since 1960. At the same time, black populations in traditionally integrated cities including New York, Chicago, and Detroit have dropped for the first time in American history.
