Signs of Spring

Signs Of An Active Beaver Pond

4-7-14  floating beaver logs IMG_0159Beaver ponds have finally started to melt, making it easy to determine whether or not there have been beavers living in any existing lodges over the winter. The tell-tale sign is floating de-barked sticks and branches. During the winter, beavers leave their lodge and swim out to their underwater food supply pile and haul branches back into the lodge where they chew them into foot-long pieces for easy handling. The bark is removed and eaten as the beaver holds the stick and turns it, much as we consume corn on the cob. When little or no bark remains, the stick is discarded out in the open water. These sticks remain hidden underneath the ice on the surface of the water until warm weather arrives and the ice begins to melt. At this point the sticks and branches become visible, and often extend several feet out from the lodge. These sticks will not go to waste, but will be used for dam and lodge repairs.

Early Saxifrage Flowering

5-8-13 early saxifrage153Early saxifrage (Micranthes virginiensis) is well named – it flowers early in the spring, and is often found growing in or on rocks. (The name saxifrage derives from the Latin words “saxum” meaning rock and “frangere,” to break. When the small seeds of saxifrage lodge in rock crevices and germinate, the plant looks as though it split the rock.) If you look closely you’ll see that early saxifrage’s flower stalk has many hairs – they are glandular and their stickiness is thought to deter ants from taking nectar from the flowers, so that it can attract more efficient pollinators.


Eastern Commas Flying

4-23-13 green comma IMG_9353Commas are a group of butterflies also known as anglewings (for obvious reasons). There are several species of commas in New England, all of which have a silver mark in the shape of a comma underneath each hind wing. Like mourning cloaks, these butterflies overwinter as adults in bark crevices, logs or other protected spots. You often see them in the woods, where they feed on tree sap, mud, scat and decaying organic matter. When perched with their wings closed, they are extremely well camouflaged and easily mistaken for a dead leaf.


Hepatica Blooming

4-18-13 hepatica DA8A9542Hepatica has finally opened its hairy buds and greeted the world with its beautiful white, pink, blue and lavender blossoms. Typically the only wildflowers to appear earlier than this member of the Buttercup family are skunk cabbage and coltsfoot. Like many flowers, hepatica blossoms open on sunny days, and close at night and on cloudy days. This prevents rain from washing out the pollen and nectar which help attract pollinating insects, including early-flying bees and flies.


Silver Maple Flowering

4-2-13 silver maple IMG_8305Silver maple (Acer saccharinum) is second only to skunk cabbage when it comes to early spring flowering. Even with our nights still well below freezing, silver maple trees are bursting with blossoms. This close relative of red maple bears its male (pictured) and female flowers separately, sometimes on the same tree and sometimes not. Silver maple’s sap can be tapped and boiled into syrup, but the yield is much less, and it’s only about half as sweet as that of sugar maple.


Annual Moose Molt

3-15-13 moose hair IMG_6412Many mammals have two molts a year, producing a winter and summer coat. Moose only have one annual molt, and it occurs in early spring. Their winter coat consists of long (up to six inches on neck and shoulders), hollow guard hairs and a thick undercoat. In early spring the faded and ragged winter hairs are shed and replaced with short, dark, shiny hairs. Molting starts on the shoulders and proceeds along the sides of the neck and back over the moose’s body. Adult bulls molt first, the cows and yearlings shortly after. Pictured is a beaver-cut tree which was used by a moose to scratch off loose winter hair.
