Beavers Consuming Herbaceous Plants

8-31-16 beaver cutting fern 052

One associates Beavers with a fairly strict diet of bark and twigs. While their winter diet consists primarily of woody plants, they consume a variety of herbaceous and aquatic plants (as well as woody) during the spring, summer and fall months. Shrubs and trees make up roughly half the spring and autumn requirements, but as little as 10% of the summer diet when herbaceous plants such as sedges and aquatic plants become available.

Recent observation of a local active Beaver pond revealed that Interrupted Fern (Osmunda claytoniana), Jewelweed/Touch-Me-Not (Impatiens capensis) and grasses are high on the list of preferred foods of one Beaver family during the summer, although woody plants such as poplars (Populus spp.) and Paper Birch (Betula papyrifera) have also been consumed in fairly large quantities.   All too soon Beavers in the Northeast will be limited to the bark of branches they’ve stored under the ice. Until this time, they take advantage of the accessibility of more easily digested herbaceous plants.

Ruby-throated Hummingbirds Migrating

9-7 female hummer IMG_1097Anyone with a hummingbird feeder knows that finally female and juvenile Ruby-throated Hummingbirds can feed without fear of being driven off by male hummingbirds, due to the fact that the males have, for the most part, headed for warmer climes. All summer the males do their very best to have sole occupancy of feeders. When the time for hummingbirds to migrate south arrives in the Northeast, males leave first, then females, and lastly, juveniles. The fall migration of hummingbirds occurs just at the time of peak of Spotted Jewelweed (Touch-Me-Not) flowering, suggesting this flower is an important nectar source during this time and may influence the timing of migration. Many of the hummingbirds visiting feeders now are migrants.
