Additionally, this largest of songbirds is also known for is aerobic alacrity - flying upside down, doing barrel, etc - and playful proclivities.</p><p>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.</p> Fri, 11 Jan 2013 05:00:00 +0000 Chris Martin & Francie Von Mertens 19838 at The Common Raven Is Exceptional Crossbills Coming to NH? <p></p><p>A poor cone crop in Canada this year is driving crossbills south of the border in search of food.</p><p>As volunteers fan out across the state for the annual <a href="">Christmas Bird Count</a>, they’re likely to see two noteworthy species down from the north this year.

Cranberries are a wetlands obligate, meaning they grow in wetland soils, so keep a watch for these low, trailing plants when you're out exploring river edges and soggy lowlands. And then return in November for the harvest. Many berries survive through the winter freeze to provide a spring snack.</p> Fri, 16 Nov 2012 05:00:00 +0000 Chris Martin & Francie Von Mertens 15398 at Wild Cranberry Relish Forest vs. Tree Cover <p>We were all duped by media reports this summer that NH had exceeded Maine for the highest percentage of <u>forest</u> cover in the US.

These aren't the New England locals, flying low from golf course to cornfield.</p><p>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.</p> Fri, 02 Nov 2012 04:00:00 +0000 Chris Martin & Francie Von Mertens 15392 at What's Good for the Goose Thoreau Remembered <p>Henry David Thoreau's death 150 years ago has inspired memorial events in Concord - the Massachusetts Concord - but Thoreau passed through our Concord on a trip by boat and foot that led to his first book.</p> Fri, 05 Oct 2012 04:00:00 +0000 Chris Martin & Francie Von Mertens 10389 at Thoreau Remembered Goldfinches, The Late Nesters <p>The bird world quiets down by late summer - but not the American goldfinch, one of the most common backyard birds. September brings the chatter of young goldfinches as they follow their male parent. They beg noisily, perched with head thrown back and trembling wings.</p><p>Most songbirds switch their diet to high-protein insects when feeding their young, and they nest earlier when insects are most bountiful. For example, chickadees that keep bird-feeders busy in winter disappear in summer as they forage for insects not birdseed.</p> Fri, 21 Sep 2012 04:00:00 +0000 Chris Martin & Francie Von Mertens 10388 at Goldfinches, The Late Nesters
