Ducks

Hooded Mergansers Fledglings are Dispersing

7-18-14 young hooded merganser 041Within 24 hours of hatching, Hooded Merganser ducklings leap anywhere from 8 -90 feet from their arboreal cavity nest down to their mother, who is calling to them from the water below. Capable of swimming and diving right away, the ducklings begin feeding themselves immediately. Weighing little more than an ounce, they mostly eat insects, including backswimmers, water boatmen and diving beetles. Eventually, as the ducklings grow, they work their way up to fish and crustaceans — particularly crayfish, such as the pictured merganser has caught. In addition to its size, the lack of a real “hood” indicates that this Hooded Merganser is a youngster.

Common Mergansers Taking Flight

common mergansers pattering 425Most ducks can take off nearly vertically from either water or land. However, when taking off from a body of water, unless alarmed, Common Mergansers usually patter along the surface for several yards before taking flight. One would imagine that their flight might not be any more graceful than their take-offs, but the opposite is said to be true of females looking for potential nesting sites. They have been observed maneuvering easily among tree branches seeking a suitable tree cavity in which to lay and incubate their eggs, and once they have found a nest site, they appear to enter and leave their nest holes with ease.

The Eyes of Common Goldeneyes

3-31-14 lone common goldeneye on ice 380Common Goldeneyes, birds of the boreal forest, overwinter as far north as open water permits, which includes parts of northern New England most years. These birds get their common name from the color of their eyes, but their eyes don’t attain this golden color until their first winter. When they hatch, Common Goldeneye ducklings have gray-brown eyes. Their eyes turn purple-blue, then blue, then green-blue as the ducks age. By the time they are five months old, their eyes are pale green-yellow. They turn bright yellow in males and pale yellow to white in females by mid-winter.

Beaver Ponds & Waterfowl

6-5-13 mallard & ducklings 151The relationship between beavers and waterfowl is a strong one. In creating ponds and wetlands, beavers provide valuable waterfowl habitat. Beaver ponds are attractive to most dabbling duck species, particularly American Black Ducks and Mallards (pictured). Dead snags that are often found in beaver ponds provide Hooded Mergansers, Common Goldeneyes, Buffleheads and Wood Ducks with nesting cavities. During spring and fall, beaver ponds are used by migrating waterfowl, such as Green-winged Teal and Ring-necked Ducks, for the fuel they provide (aquatic invertebrates, plant seeds, tubers, buds and rhizomes). Waterfowl surveys in 2002 in Wyoming found that rivers and ponds with beavers had 75 times more ducks than those without beavers.


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.


Wood Duck Courtship Displays

4-3-13 wood ducks  IMG_6045It’s been my life’s dream to witness the fledging of young wood ducks from their tree cavity nest in response to their mother’s calls below – perhaps this will be the year! Adult wood ducks have recently returned to northern New England, having already formed mating pairs. They now proceed to perform a number of courtship displays which enable them to maintain this pair bond. The most common display involves the male’s turning the back of his head towards the female as he swims in front of her while holding his wings and tail high. Chin-lifting, feather-shaking, wing-preening, neck-stretching and bill-jerking are just some of the displays that occur during wood duck courtship.


A Great Christmas Present!

If you’re looking for a present for someone that will be used year round, year after year, Naturally Curious may just fit the bill.  A relative, a friend, your child’s school teacher – it’s the gift that keeps on giving to both young and old!

One reader wrote, “This is a unique book as far as I know. I have several naturalists’ books covering Vermont and the Northeast, and have seen nothing of this breadth, covered to this depth. So much interesting information about birds, amphibians, mammals, insects, plants. This would be useful to those in the mid-Atlantic, New York, and even wider geographic regions. The author gives a month-by-month look at what’s going on in the natural world, and so much of the information would simply be moved forward or back a month in other regions, but would still be relevant because of the wide overlap of species. Very readable. Couldn’t put it down. I consider myself pretty knowledgeable about the natural world, but there was much that was new to me in this book. I would have loved to have this to use as a text when I was teaching. Suitable for a wide range of ages.”

In a recent email to me a parent wrote, “Naturally Curious is our five year old’s unqualified f-a-v-o-r-I-t-e  book. He spends hours regularly returning to it to study it’s vivid pictures and have us read to him about all the different creatures. It is a ‘must have’ for any family with children living in New England…or for anyone that simply shares a love of the outdoors.”

I am a firm believer in fostering a love of nature in young children – the younger the better — but I admit that when I wrote Naturally Curious, I was writing it with adults in mind. It delights me no end to know that children don’t even need a grown-up middleman to enjoy it!
