Birds

The song of the veery is a haunting, ethereal song. Males sing at dusk, a time when not many other birds sing and daytime winds have calmed. It's also a time when the air turns damp; dense, moist air transfers sound waves better than dry air.

If you listen to the song carefully, you can hear an echo or tremolo effect (more on this below), because songbirds have, essentially, a double voice box that can produce two notes at the same time. (The left voice box is lower pitched than the right one.) In a sense, a singing veery harmonizes with itself.

I've learned that a sighting of a bluebird on a bird watching field trip stops everything. We'll pause a long time as people take turns looking through the spotting scope. Involuntary gasps of pleasure, "oohs" and "aahs" and "ohmygods."

Favorite Phoebe Nest

May 9, 2014
Dave Anderson

A little phoebe nest is tucked beneath the rafters in my backyard woodshed like a miniature wreath. It’s a curious little relic to behold during those long, cold snowy weeks of hauling winter cordwood. By May, it once more cradles eggs and tiny nestlings.

The elegant little nest cup is woven of green moss, lined with pine needles and dried grass and cemented with warm mud. During winter, that Phoebe’s nest carries the promise of time travel to these fleeting mornings of early May when warm sunshine drenches the Lane River Valley - already now awash in spring bird songs.

We went into the field this week to speak with Carol Foss, Member of the International Rusty Blackbird Working Group and NH Coordinator of the Rusty Blackbird Spring Migration Blitz

Rusty Blackbird populations have fallen over the last century: by between 80 and 90-percent. Last fall the working group decided to make careful study of the spring migration, and coordinated hundreds of volunteer scientists along the migration route to track the birds.

Move over robins; red-winged blackbirds are the real harbingers of spring.

The male’s scratchy “oak-a-lee” songs are heard when the world is still blanketed with snow and maple sap is just beginning to flow. Males return north well before females, and the early bird does get the worm. In this case the metaphorical worm is prime breeding territory.

On Monday, the Union Leader reported that the peregrine family nesting high above Manchester had found a new papa bird. After her previous mate injured his wing and was taken in for surgery, the female falcon eventually left the nest in search of food. Within 72 hours of her former mate's disappearance, she successfully found a new male for her nest.

Saw-Whet Owls

There are a lot of unusual sounds out there in the natural world. Here’s one from the nighttime forest, often heard this time of year.

No, it’s not a school bus backing up.

It’s a tiny owl, the northern saw-whet, and it’s a lot more common than bird surveys suggest. As you might imagine, small birds active only at night are not easy to survey. Also important to note is that because they're the favorite meal of the much larger barred owl, their survival depends on keeping a low profile—usually under cover of dense conifers.

Snowy Owls In The Granite State... And Beyond!

While the weather these days might not be an indicator, spring is officially here. Which got us thinking in the Word of Mouth pod...about the birds and the bees. And also birds and bees. On today's show a conversation about the most awkward talk a parent has to have: "the talk." Also, a bird expert tells us about this year's unusual snowy owl migration. We'll also hear about the next great frontier in self tracking apps: fertility apps.

The Common Junco And Its Uncommon History

Mar 7, 2014

A huge question in evolutionary biology is the very basic one: How do species form? It turns out that the Dark-eyed Junco, one of the most common birds at winter feeders, is providing a  clear picture of that process.

First, a quick review of what defines a species:

A Snowy Invasion

Jan 24, 2014
Tom Magliery via flickr Creative Commons

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.

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.

Beauty In The November Grays

Robert Frost ended a short poem on life and nature with the line, "Nothing gold can stay." October has ended after delivering golden fall days that make us regret the indoor tendencies of our lives. Stark November is at the doorstep now. We reacquaint ourselves with ridge-lines visible through bare trees and with stone walls along fields cleared and worked in a time when days were spent more outdoors than in. 

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.

Marking The Seasons With Hawks...And Apples

Oct 4, 2013
NH Audubon

At Carter Hill Orchard in Concord, the changing varieties of ripe apples measure out the transition of summer into autumn. Early Paula Reds, which ripen in August, give way to tart McIntoshes, juicy Macouns, and sweet Cortlands, as September wears on.  By early October, yellowed leaves and frosty mornings signal late-season apples with appropriate names: Gibson Golden and Honey Crisp. 

The Company Of Cuckoos

Jul 26, 2013

Elusive, secretive birds often are the most satisfying to discover, and for me the black-billed cuckoo ranks near the top. Hearing a bird is usually the best way to find it, but attentive ears are needed to detect this cuckoo's song: a subtle, slow and hollow-sounding "cucucu – cucucucu." The song in no way resembles the bold double notes of a cuckoo clock that mimic the song of the common cuckoo, a species that nests across Europe and Asia.

Dear EarthTalk: I understand that pet cats prey on lots of birds and other "neighborhood" wildlife, but isn't it cruel to force felines to live indoors only? And isn’t human encroachment the real issue for bird populations, not a few opportunistic cats?                       -- Jason Braunstein, Laos, NM

Ladies First: Role Reversals Of Spotted Sandpipers

Jun 14, 2013

From shores of wild waterways to not-so-wild urban ponds, a small bird startles up and flies low over the water with quick, stiff wingbeats.
 

It's a spotted sandpiper, a small shorebird often encountered along freshwater shorelines.

Shorebirds come in all sizes, and spotted sandpipers are in the short, stocky category. Despite coloring that blends well with sand and rocks, there's a movement that often gives spotted sandpipers away: they bob up and down as though seized by intense hiccups. When stalking prey, however, their teetering stops.

Small Bird, Big Song

May 31, 2013

As spring moves into summer, birdsong is in full voice. The winter wren, weighing only one third of an ounce, is tiny in stature but boasts an energetic song made up of over 100 individual notes.

Why such a big song from such a small bird? The winter wren makes its home among root tangles and boulders, and unlike birds of open spaces, birds particular to dense, enclosed spaces need a strong song to have it carry far.

Birdsong, Translated

Ashour Rehana / Flickr/Creative Commons

With birds tuning up for the breeding season ahead, here are some memory tricks to help you recognize a few of the more common songs.

Robins can be heard in just about all habitats across the state and the nation. Their whistled song is often translated as, "Cheer-up. Cheerily. Cheerio."

Another song easy to "translate" is the flight song of goldfinches. Someone somewhere interpreted it as, "Potato chip! Potato chip!"    

How Many Birds?

Apr 5, 2013
Lillian Stokes

How many bird species might an attentive backyard birdwatcher, or "birder", find?

The term "backyard" means any nearby open space, such as a stream corridor or an open field with forest edge. The more habitat types a backyard has, the better.

Don and Lillian Stokes, of Hancock, NH, have a backyard that includes the Contoocook River, a distant ridgeline, open field, wetlands, and forest, not to mention many birdfeeders and birdhouses to attract their feathered friends. Like many active birders, they keep a backyard list of their sightings from over the years.

Unique Nests

Mar 22, 2013

A bird can be identified by the different splashes of color on its feathers, or its distinct call, but did you know that you can also tell a bird by the way it builds its nest, even if it's empty?

Just as birds in all their variety evolved from the very first species, their nests have evolved in equal variety over millions of years. Every bird builds a nest unique to its species.

High Perch: Peregrines Nesting In The City

The peregrine falcon: Fierce, fast, high cliff dweller, symbol of the wild. All true, but increasingly peregrines can be found inhabiting urban canyons of concrete and steel.

Welcome to March! If you walk in the forest this week, you might detect the song of a non-descript little brown bird called the "brown creeper." 

Brown creepers are hard to see. Their habit is to creep upward on tree trunks, often in spiral fashion remaining well-hidden. It sports mottled "tree-bark pattern" camouflage.

Ravens Are Playful And Smart

Among the many stories about the intelligence of ravens, and their playfulness is one from Mount Monadnock. As the sun was setting a hiker shared the mountaintop with a gang of ravens taking turns leaping  into a strong updraft, tumbling up, then circling around to leap again.

The Common Raven Is Exceptional

Jan 11, 2013

The stately Raven has garnered many connotations over the years, chief among them are for the bird’s intelligence. Additionally, this largest of songbirds is also known for is aerobic alacrity - flying upside down, doing barrel, etc - and playful proclivities.

Stories of their intelligence abound, including one that involves Cheetos. A wildlife biologist was attempting to trap and band ravens. To lure them in, he spread Cheetos on snow and the bright orange color soon attracted several ravens, which were then snared by leg traps under the snow.

Crossbills Coming to NH?

Dec 28, 2012

A poor cone crop in Canada this year is driving crossbills south of the border in search of food.

As volunteers fan out across the state for the annual Christmas Bird Count, they’re likely to see two noteworthy species down from the north this year. Both are named "Crossbills" for unique bills that actually do cross, all the better to pry seeds from a conifer cone.

Birds of a Feather

Ken Sturm/USFWS

Taxonomy is the attempt to place all plant and animal species in a logical order based on relationship. Two thousand years ago. Aristotle classified birds by appearance and behavior, such as birds that swim, birds of prey, and birds that sing.
