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 http://nhpr.org Wild Cranberry Relish Forest vs. Tree Cover http://nhpr.org/post/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.

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 http://nhpr.org What's Good for the Goose Thoreau Remembered http://nhpr.org/post/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 http://nhpr.org Thoreau Remembered Goldfinches, The Late Nesters http://nhpr.org/post/goldfinches-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 http://nhpr.org Goldfinches, The Late Nesters
