Common Loons: Feeding Chicks

7-4-14 loons feeding 202Both parents provide their young with food (small fish, crayfish, etc.) several times an hour, especially early and late in the day. (This practice continues, in a more limited way, long after the young loons can provide for themselves, right up until the parents migrate — before the juveniles — in the fall.) Often food delivery takes place when the chick is in the water, but occasionally it occurs while the chick is on the parent’s back during its first week or so of life. Initially the adult loon catches prey, swims up to its chick while holding the prey in its beak until the chick grasps it and swallows it. By the third week, the parents start dropping the fish or crayfish in the water in front of the chick, forcing it to learn how to catch its own food. Needless to say, in the beginning, the adults must have great patience, retrieving and dropping the prey time after time while the chick acquires the skills necessary to catch it. (Photo: Adult with fish approaches mate while making a soft mewing sound. Mate raises wing, chick emerges and reaps the benefit of home delivery.)

Common Loons: Brooding Chicks

7-2-14 common loon with chicks-broodingIMG_3215While loon chicks can swim as soon as their down dries, they are not able to regulate their body heat for their first two weeks of life and are dependent upon their parents for warmth. (A lot of the chick’s heat is lost through its feet when it is in the water.) Whereas most birds provide this warmth (in a process called brooding) in the nest, Common Loons brood their young on the water during this period. The chicks simply climb up the backs or sides of a parent while the parent raises its wing. Once the chicks are situated on the back of the loon, the adult lowers its wing, sheltering the vulnerable chicks from the elements. If the sun is out, the wind is slight and the temperature is warm, the chicks will come out from underneath the wing(s) and ride around enjoying the view. If the wind picks up or the temperature drops, the chicks will crawl back under their parent’s wings, totally hidden from view.

Avian Parents Hard At Work

robin with food 077To appreciate the parental demands on birds, consider the feeding habits of a pair of American Robins with a nest full of young. Both parents feed their 3 – 4 nestlings, delivering 6 – 7 feedings an hour, each one to a single nestling. (Parents tend to arrive with food at a particular location on the nest rim, so there is much jockeying for a position near this spot on the part of the nestlings.) Each nestling gets 35-40 feedings per day. This amounts to almost half a pound of food delivered to the nest every day for the 13 days that young are in the nest. Even then, the parents’ work is not done, as they continue to feed their fledglings for up to three weeks after the young leave the nest.

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.


Killdeer Nesting

5-7-13 killdeer by Sadie IMG_7096_croppedThis is the time of year when it pays to watch where you walk – there are a number of ground nesting birds, some of which, including killdeer, may choose your lawn or even your garden to build their simple “scrape” nest. Typically killdeer nest on the shoulders of roads, gravel roof tops, fields and gravel parking lots. The nest is very primitive, and there’s actually very little to it — killdeer scrape a slight depression in the ground, to which they often add bits of material, including white objects such as shells and bones. Their pigmented eggs are extremely well camouflaged. The young precocial killdeer chicks are on their feet and feeding themselves as soon as their down feathers dry. (Photo by Sadie Richards)


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!


Great Horned Owl Fledglings

Hardy birds that they are, Great Horned Owls are one of the earliest nesting birds — you can find them on nests in January, February and March, even in northern New England. Eggs are incubated for about a month, typically in March or April with young usually hatching in May or June. The nestlings remain in the nest for six or seven weeks before fledging. Unable to fly until they’re ten or twelve weeks old, the fledglings follow their parents around and continue to be fed and cared for by them until the fall. These two fledglings were sticking close together as they made their raspy begging calls from high in a white pine. Both their calls and the down that was visible on their heads told me that they were this year’s young.
