Something Wild: The Eerie Sounding Veery

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.

The 'Dirt' On Soil

Credit NRCS Soil Health via flickr Creative Commons

This time of year finds a lot of people working in their gardens. Good gardeners pay attention to their soil.Just like above ground, there’s a diverse world of wildlife below ground competing for space, nutrients, and performing roles that support life on Earth.

Microscopic bacteria species by the millions; root fungi that deliver nutrients to plants; worms, ants and other insects aerating the soil and adding nutrients through their droppings and—post mortem—as their bodies decay. Minerals laid down long ago are constantly breaking down through weather and erosion.

Water In The Trees

The patter of rain. Fingers of wind comb the canopy of tender leaves. These are exotic sounds of the new tree canopy in late May. New Hampshire forests are adapted to withstand rigors of wind and weather. Leaf structures reflect inner tree plumbing we rarely consider.

Tubes of the water-moving "xylem" are coiled like springs that stretch and recoil to some degree and not break the tension of water in these drinking straws.  Stem fibers of differing lengths break at different stress points

A Soft Spot For Bluebirds

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."

Predictions for a Rough Allergy Season Following a Cold Winter

Biologists say this year’s cold Winter and late Spring could mean a wallop of an allergy season, a so-called “pollen vortex” adding to a longer trend toward higher pollen counts, due to climate change.

Tiny Tree Flowers

Spring blossoms of our largest plants - woody trees - are small and inconspicuous. Trees flower early - before leaves emerge. While showy wildflowers on the forest floor rely on specialized insect pollinators, forest trees do not.

Trees rely on wind-pollination of flowers to yield summer seeds and autumn nuts. Flowering before leaves emerge ensures greater air circulation among pollen-producing male stamens and female pistils containing ovaries.

Red-Winged Blackbirds

Red-winged Blackbird -- Agelaius phoeniceus

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.

Spring Sunlight

Daylight floods a rural NH valley. A rooster crows in the village. The morning songbird chorus features mourning doves, red-wing blackbirds, a cardinal. The symphony will soon swell with grouse drumming, wood thrush flutes and a crescendo of warbler songs.

Strong sunlight of lengthening days is the catalyst that controls circadian rhythms influencing production of hormones - in birds, wild mammals and people.

Granite Staters Relish Belated Springtime Weather

After a long winter and several false starts, it looks like New Hampshire might finally be heading into spring. 

Mild temperatures on Sunday brought many Granite Staters outside to enjoy the weather.  Concord resident Annie Morgan brought her eight-year old son to a city park.  And she was confident that this time, spring was here to stay.  

“Well I’m determined!  It’s not going anywhere," she said with a chuckle.  "No, we’re not getting any more snow, and it’s going to be beautiful!”

Historic Ice-Out Of Winnipesaukee Expected

The man who officially declares the annual ice-out of Lake Winnipesaukee says this year’s announcement could be a record-setter.

Dave Emerson of Emerson Aviation in Gilford said this winter’s cold and snow may mean it’s early May before he can declare what some consider the official start of the New Hampshire summer season.

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.

Hey, is that a bus backing up?

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.

The Sugaring Life

 Maple time in New England brings out the essence of the trees and the character in the people. For those who love trees, a tongue-tip taste of fresh maple syrup is a sacrament, maple communion at the end of a long winter. To ingest the distilled essence of trees confers the spirit of the forest itself.

Vernal Equinox Means Equal Night

The Vernal Equinox has arrived! For one brief moment, everywhere on planet Earth, day and night are equal: 12 hours from sunrise to sunset and sunset to sunrise.

The length of daylight compared to dark, is known as photoperiod. Seasonal changes in photoperiod  trigger a lot of changes in plants and animals. Many plants are known as short-day species; they flower after the summer solstice when days are getting shorter. Plants that bloom in spring are known as long-day species.

3.20.14: The Birds, The Bees, & The Birds And The Bees

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.

For Some Plants, Getting Green Means Starting Early

For some plants, the race to harvest sunlight to make food starts early, in March. Skunk cabbage and many alpine plants begin to photosynthesize under the snow using red "anthocyanin" pigments which can absorb the longer-wavelength blue light at the ultra-violet end of the spectrum--even while buried beneath the snow.
