Spotted Sandpiper Role Reversal
Spotted Sandpipers are a relatively easy shorebird to identify, with their spotted breasts, their constant body-bobbing/teetering and the stiff beat of their wings. Although they are a shorebird, they can be found near freshwater ponds and streams throughout North America. Spotted Sandpipers differ from most birds in that the male and female roles are completely reversed when it comes to breeding – from courtship to parental care. The females establish and defend their territory, often arriving on nesting grounds before the males. Females court the males, performing display flights as well as strutting displays on the ground. Males, usually less aggressive and smaller in size, do the lion’s share of incubating the eggs and brooding the young chicks.
Common Loons Nesting
Generally speaking, Common Loons return to northern New England from their coastal wintering waters sometime in April or May. Males and females pair up after they arrive at their ponds, and several weeks later they breed and build a new nest or renovate an old one, with the male choosing the actual nest site. Successful nests sites are often reused from year to year, especially if the male returns. Protection from wind, waves and predators is paramount. Because their hind legs are positioned so far back on their body, loons are awkward walkers, at best. Thus, they usually build their nest adjacent to water so that they can easily slip onto and off of it. The nest is constructed during the day by both adults and is made of vegetation that the loons collect close to the nest. A loon often sits on the nest while collecting material, stretching its head down into the water in order to retrieve vegetation which it then places on the nest. Two eggs are laid, usually between mid-May and early June. After being incubated by both parents, the eggs hatch in roughly 28 days. As this photograph indicates (egg just visible below loon’s body), material continues to be added to the nest during incubation.
Beaver Ponds & Waterfowl
The 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.
Male House Sparrows Rise to the Occasion
The House Sparrow’s (also known as English Sparrow) reputation leaves a bit to be desired. It is an introduced species which has thrived in North America to the point where it is considered a nuisance species and an agricultural pest. Its tendency to displace native birds such as Eastern Bluebirds and Tree Swallows from nest boxes does not endear it to many bird lovers. However, one has to acknowledge the fact that male House Sparrows are the exception rather than the rule when it comes to parenting. Males help choose the nest site, build the nest, incubate the eggs, brood and feed the nestlings and keep the nest clean by removing the nestlings’ fecal sacs. That’s more than can be said for some of our most admired species, such as male Ruby-throated Hummingbirds, which disappear shortly after copulation.
Hermit Thrushes Nesting
Hermit 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.
Baby Painted Turtles Migrating to Ponds
In May, at the very same time that adult painted turtles are laying their eggs, some of last year’s young turtles are migrating from their nest site to ponds or rivers. Painted turtle eggs actually hatch in late summer, with the young turtles remaining inside the nest cavity for varying amounts of time. Here in New England, in the northern part of their range, they often overwinter in their nest and emerge the following spring.
Killdeer Nesting
This 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)
Great Blue Herons Mating
Numerous displays lead up to the mating of great blue herons – neck stretching, bill clacking, wing preening, circling flights, twig shaking, crest raising, neck fluffing, to name but a few. After this elaborate courtship comes copulation, which is not nearly as showy. Copulation typically takes place on the nest. The male places one foot gently in the center of the female’s back. The female leans forward, bends her ankles and holds her wings slightly away from her sides while the male lowers himself, often flapping his wings. Once the job is done, the male flies off. If you look closely you can perhaps make out that the male is grasping the female’s head/neck while copulation takes place.
Eastern Chipmunks Soon to Give Birth
It’s possible that this chipmunk is preparing a nesting chamber in her underground burrow, judging from the amount of dirt that is on her. Sometime between February and early April chipmunks mate. Roughly a month later they give birth to 3 to 5 young in a bulky nest of leaves inside a 24” x 15” x 10” chamber. Within a week, hair and stripes will be evident on the young chipmunks. In about a month, they will venture out of the burrow, looking like small adults.
Common Raven Defends Nesting Territory
Common ravens are known for their aerial acrobatics, often doing rolls and somersaults and other amazing tricks. According to Cornell Lab of Ornithology, one bird was seen flying upside down for more than a half-mile. Young birds are fond of playing games with sticks, repeatedly dropping them and then diving to catch them in mid-air. The pictured raven, however, was much too busy to be doing cartwheels in the sky. It has a nest with eggs nearby, and during its morning patrol encountered a red-tailed hawk which it drove out of sight in a matter of seconds. Although small mammals make up most of a red-tail’s diet, they are known to also prey on smaller birds, including defenseless nestlings, which the ravens will have in the next few weeks. (Because of the angle, the 24-inch-long, 53-inch-wingspread raven looks disproportionally larger than the 19-inch-long, 49-inch wingspread red-tail.)
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!
Bird Nest I.D.
Now that the leaves are off the deciduous trees, it is much easier to see where songbirds nested this past summer. Just as every songbird species has a specific song unlike that of other species, each species also constructs nests that are very similar to each other, but not to other species’ nests. Thus, one American robin nest looks a lot like any other American robin nest – nests of one species are usually found in roughly the same kind of habitat, with the same dimensions and similar building materials. Sometimes there are key characteristics that help with identification – grape vines and a lining of rootlets told me a gray catbird built the nest in the photograph. (Plastic told me humans weren’t far away.) Most songbirds only use their nest once; after the young have fledged, they abandon their nests. Before the weather and/or critters recycle this year’s nests, take advantage of the opportunity to examine these gems of avian architecture up close. (A federal permit is needed in order to collect bird nests.) A good book for nest identification is Peterson’s Field Guide to Bird Nests.
Great Blue Heron Chicks Yawning
I had to laugh recently when I noticed a chain reaction going on in a Great Blue Heron nest I was watching. There were five chicks, and one of them yawned. At least I presume it was a yawn, though perhaps it could have be re-aligning its beak or perhaps cooling off. Exactly like humans, each of the remaining four birds followed suit and proceeded to stretch their beaks open wide in succession. It struck me as quite comical, especially when I discovered myself yawning as I observed the heron chicks doing the same.
Great Blue Heron Nests
Great Blue Heron chicks are getting big enough so that you can easily observe them (can you find all four?). Occasionally you can even detect flies and other insects buzzing about them, which, given the fact that nest sanitation is not a priority for herons, is not surprising. While the parents do toss the eggshells out of the nest, feces, partly eaten prey and even dead chicks often remain in the nest. Also, parents feed their young by regurgitating into the nest and the chicks will regurgitate when disturbed. Unlike most song birds, Great Blue Herons re-use their nest year after year. It is quickly apparent why they add more sticks and boughs to their nest every breeding season – were that housekeeping for humans was that simple!
Red-tailed Hawk Nestling
The Red-tailed Hawk nest that produced two fledglings last year is in use again this spring. In the past month the nestlings have gone from tiny white powder puffs to nearly equaling their parents in size. Down is still visible, especially on their heads, but contour feathers are quickly replacing them on other parts of their body. Soon there will be wing stretches and flapping, as well as hopping about on nearby branches in preparation for fledging.
