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.

Common Loons: Hatching

7-2-14  loons #3-hatching  395Peeps can be heard from inside an egg before the chick starts to crack it open (a process referred to as “pipping”) with its temporary “egg tooth.” The eggs hatch in the order laid, not at the same time. The chicks are covered with sooty black down which is often dry within an hour of hatching. While waiting for the second egg to hatch, the parent loon often takes the firstborn chick for its maiden swim, returning to the nest with the chick to incubate the remaining egg until it hatches. By the third week, the chick’s black down is replaced by brownish-gray down.

Red-shouldered Hawks Nesting

red-shouldered 008Male red-shouldered hawks put on an impressive courtship display for females. The male enacts a “sky dance” in which he soars while calling, then makes a series of steep dives toward the female, climbing back up in wide spirals after each descent, before finally rapidly diving to perch upon the female’s back. After copulation, the female lays her eggs in a nest which she has most likely used for several years. It is usually located below the canopy but more than halfway up a tree, generally in a crotch of the main trunk. Both male and female hawks build or refurbish the nest, adding fresh evergreen sprigs to it throughout the nesting period (eastern hemlock in pictured nest). Females do most of the incubating and brooding of the young, with the male providing food. The nestlings pictured are roughly two weeks old; in three or four weeks they will begin to climb out on branches away from the nest, in preparation for fledging.


Hermit Thrushes Nesting

5-21-13 hermit thrush nest 222Hermit thrushes, Vermont’s state bird, are typically ground nesters east of the Rocky Mountains (west of them, they tend to nest off the ground) and often, as in this case, choose a nest site that is in a patch of Lycopodium, or ground pine. Usually a branch from a nearby tree, a fern, or some other taller vegetation provides cover and effectively conceals the nest. The female hermit thrush builds the nest and begins incubation after the last of her three or four eggs is laid. Twelve days later the eggs hatch, and twelve or thirteen days after that the young fledge.


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!


Fledglings

Baby birds like this robin are starting to fledge, and it’s the time of year when we see them on the ground, looking very vulnerable. Often we assume that such a bird has been abandoned, and with all good intentions attempt to “rescue” it and finish raising it ourselves. Young birds recently out of the nest are still cared for by their parents for several days, but the parents aren’t always in sight. Usually one parent is nearby, keeping an eye on its fledglings, feeding them and teaching them survival techniques such as where to find food and water and how to avoid predators – skills humans can’t provide. If a bird has feathers, is hopping around, and has a tail an inch or so long, it has probably fledged and not fallen from its nest accidentally. A good rule of thumb is to watch the bird for at least two hours to see if a parent comes to it before taking it to the nearest bird rehabilitator.
