migration

If you visit Appledore Island during spring bird migration, consider wearing a helmet.

“Yeah I mean the herring gulls will hit you and it’s jarring, but the black-backs hitting you can do some serious damage,” says Sarah Courchesne, a sea-gull researcher with Tufts University, as she and her students suit up to go out and catch seagulls.

The gulls that nest around the research station get very protective this time of year

Warm Weather Heralds Prime Bird Watching Season

If this past winter had you longing for sunny days and spending more times outdoors, you’re certainly not alone. As northerly winds make way for the warm southerly breezes, you’ll likely notice quite a few more birds at the feeders and songbirds chirping away out of sight. Spring is prime-time for bird watching and while you may have noticed the return of the Red-winged Blackbirds back in March, and perhaps a surge in waterfowl sightings, there a plenty more feathered friends winging their way north.

After a long and frigid winter, the sound of spring peepers singing from beaver bogs is a welcome one for New Englanders. But before frogs can start their songs spring, a massive migration has to take place. On a handful of spring nights, millions of amphibians mobilize all at once.

November is a great time to spot golden eagles. They are a rare sight in New Hampshire, but they do pass through the state on their annual migration. Right now they’re on their way south to winter in the central Appalachians. They’ll pass back through the state in March on their way to Labrador and northern Quebec to nest.

Golden eagles are sometimes confused with young bald eagles, but there are differences. When bald eagles are in flight, they hold their wings flat like a plank, but golden eagle wings have a slight ‘V’ shape.

November's gray skies carry the last of the migrating Canada geese, graceful ribbons of true wild Canadians on a long-distance flight. These aren't the New England locals, flying low from golf course to cornfield.

The northerners are vocal in flight. Geese are highly social, vocal year-round as they maintain relationships both within the family grouping and the greater flock. Vocalizing by young begins within the egg before hatching, and helps build a strong family bond that lasts a full year.

Something Wild: Dragonflies Winging South

Late summer brings cool nights and clear air - and winged migration. Along with birds heading south, there's a few butterfly, moth and dragonfly species that respond to the migratory urge.

One dragonfly - the common green darner - has been studied with results that suggest there's a lot of similarities between insect and bird migration. Tiny radio transmitters were attached with eyelash adhesive to green darners which were tracked by plane and ground crews.

The autumn shorebird migration starts early. The first signs of autumn are now found moving southward along beaches and in salt marshes or high above New Hampshire's 13 miles of Atlantic coast. 

A Snowy Invasion

This year is being referred to as an "invasion year" for snowy owls, and it might be one for the record books.  

Most of the snowy owl sightings have been along the coast where a flat, open landscape resembles their native tundra. Reports from New Hampshire birders include sightings of up to nine in a single day. On Nantucket, the annual Christmas Bird Count found 33, far surpassing the previous count record of four.

  Ospreys, also called sea hawk or fish eagle, are found all over the world including here in New Hampshire, But wherever they live, when the temperature drops the birds head for the tropics. For juveniles that first migration is a crucible that only 25 to 40 percent survive.

A project in New Hampshire is tracking Granite State birds and learning about the many misadventures they have between their departure in the fall and return in the spring.

Fewer Exotic Birds in NH This Winter

Nov 15, 2013

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.

The Turkey Vulture

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.

Where Have All The Monarchs Gone?

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.

Spectrum of Birdsong

May 18, 2012

Mid-May is like rush hour in the bird world. Migrants have returned for the nesting season and the air is full of birdsong. As you might guess, birdsong is as varied as birds themselves. In fact, birdsong is defined generously to include any and all sounds they make with territorial or courtship intentions. Let's start with a traditional vocalization and then branch out.  

Coffee for the Birds

Dec 30, 2011

Have you heard about coffee that's for the birds? There definitely is such a thing: shade-grown coffee. Until recently that's how all coffee grew: in the shade on small family farms. Canopy trees above provided shade along with a natural leaf mulch that kept soil moist, prevented soil erosion, and decomposed to provide nutrients. The canopy typically included fruit and nut trees that provided food for the farm family.

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.
