Hooded Merganser

5-24-13 hooded merganser2  030Yesterday’s mystery duckling was a Hooded Merganser. Wood Duck and Hooded Merganser ducklings are very similar, however Wood Duck young possess a dark, horizontal line behind their eyes which Hooded Merganser ducklings lack. There are several ducks that nest in tree cavities in New England, including Wood Ducks, Common Goldeneyes, Common Mergansers and Hooded Mergansers. Hooded Merganser ducklings leave their nest cavity within 24 hours of hatching, in response to their mother’s calls below. They jump/climb up the wall of the cavity and hurl themselves out of the tree. Depending on where the tree is located, they fall either onto the ground, where they bounce like a tennis ball upon landing, or straight into the water. Hooded Merganser fledglings have been known to fall as far as 50 feet to the ground and then walk as far as half a mile with their mother to the nearest body of water.


Beechnuts

Birds and mammals that rely on beechnuts as a staple of their diet include black bears, white-tailed deer, fishers, porcupines, wild turkeys, ruffed grouse, wood ducks, tufted titmice, and numerous small rodents, to name but a few.  There is a good reason for this – beechnuts have about the same protein content as corn, but five times the fat content.  Beechnuts also have nearly twice as much crude protein and twice the fat of white oak acorns and about the same fat content as red oak acorns.  Given the number of husks and nuts that are on the forest floor this fall, it appears that this is a good year for beechnut mast, or seed production.  Research has shown that high beechnut production in the fall is correlated with a high percentage of reproducing female black bears in the coming winter.
