Mice Preparing for Winter

10-25-13 mouse larder 012Animals that remain active in New England throughout the year often make preparations for the colder months, when food is much scarcer. Eastern Chipmunks store up to half a bushel of nuts and seeds in their underground tunnels, Red Squirrels hang mushrooms and apples out to dry and White-footed and Deer Mice create larders, often out of abandoned bird nests. Once their young have fledged, most songbirds never re-use their nest. Mice find these empty cup-shaped containers perfect for storing seeds that they collect in the fall. The mouse that took over this Northern Cardinal nest (located in a rose bush) didn’t have to go far to collect a sizeable number of rose hips. One hopes that this isn’t this particular mouse’s only cached food, as most of the seeds (within the fleshy red covering) have been devoured. (Thanks to Marian Marrin for photo op.)

Apple Scat

10-4-13 woolly bear scat 028At this time of year it’s not unusual to find the scat of various mammals consisting mostly of apple. Red Foxes, White-tailed Deer, Cottontail Rabbits, Porcupines and Black Bears, in particular, are all avid consumers of this appetizing fruit. Birds, including Purple Finches, Cedar Waxwings and Northern Mockingbirds, also include apples in their diets . While many insects drink the juice of apples, it’s not that often you see an insect like this Woolly Bear caterpillar (the larval stage of the Isabella Tiger Moth) consuming a sizable chunk of a McIntosh apple and leaving behind tell-tale scat.

White Baneberry Fruits Mature

8-15-13 white baneberry fruit 056All parts of the White Baneberry plant (as well as Red Baneberry) are highly toxic. The fruit, called “doll’s eyes” for obvious reasons, is the most poisonous part, known to cause respiratory paralysis and cardiac arrest in humans. It does not have this effect on all mammals, however. White-tailed deer are known to browse on baneberry, and small rodents such as mice, squirrels and voles feed on the fruit. Geometrid moth larvae (“inchworms”) burrow into the fruits and their seeds while they (the fruits) are still green. A wide variety of birds, including American Robins and Yellow-bellied Sapsuckers, eat the fruit, helping disperse the plants when they excrete the brown, wedge-shaped seeds (insert). Ruffed Grouse also eat the fruits, but the seeds are destroyed in the digestive process. Oddly enough, Native Americans used the juice of Red Baneberry to gargle with as well as to poison their arrows.

Partridgeberry Flowering

7-9-13 partridgeberrey flowers2 IMG_1018In many areas the forest floor is now carpeted with flowering Partridgeberry (Mitchella repens), the creeping, woody vine found in both deciduous and coniferous woods. The pairs of white flowers occur in two forms. In the first form (pictured) the pistil is short and the stamens are long; in the second form the pistil is long and the stamens are short. This structure prevents each flower from fertilizing itself. Both flowers must be pollinated to obtain a single scarlet berry. Each berry is the result of the fusion of each ovary of the pollinated pair of white flowers. As such, each berry has two bright red spots on its surface.


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!


Common Juniper

Common Juniper (Juniperus communis) is one of the few evergreen shrubs in New England and has one of the largest ranges of any woody plant.  You often find it in old pastures and meadows, where its sharp needles protect it from most herbivores.   It is a member of the Pine family, and even though its fruits look like berries, structurally they are cones (with fleshy scales).  Whereas most of the cone-bearing members of the Pine family disperse their seeds in the wind, Common Juniper uses birds and mammals to do this deed.  Cedar waxwings, evening grosbeaks and purple finches consume quantities of juniper fruit, and many other songbirds are frequent visitors.  White-footed mice and white-tailed deer occasionally eat the fruit as well.  While not aiding the dispersal of seeds, humans do use the fruit to flavor gin.


Black Walnut

Even though a late spring frost may have reduced this year’s crop of Black Walnuts (Juglans nigra), and even though the few that made it haven’t started falling on the ground yet, squirrels have already located and started consuming this nut’s fatty meat.  Inside the green husk is the actual nut, and if you look closely at the edges of the chewed hole as well as the inner surface of the nut, you will see tiny incisor marks, most likely left by red squirrels.  This particular rodent typically chews a hole on both sides of the nut, so that it can gain access to both halves of the meat.


Skunk Cabbage Fruits

After the flowers of Skunk Cabbage, located on the knob (spadix) sitting inside a modified leaf (spathe), have been pollinated and fertilized, the fruits begin to mature. The spathe withers and dies, and the stalk that carries the fruit head elongates, growing along the surface of the ground. Initially the fruit head is green and dark purple, measures 2-3” in diameter, and has a convoluted exterior resembling that of a brain. Inside this compound fruit a circle of 10 to 14 seeds lines the periphery. By August the fruit heads will have fallen apart, and the seeds will lay on the ground where they will likely germinate or be eaten by squirrels, ruffed grouse or wood ducks.

Staghorn Sumac Seed Heads and Their Inhabitants

If you pull apart a red, fuzzy seed head of Staghorn Sumac (Rhus typhina) this time of year, you will find, in addition  to a multitude of seeds, a profusion of scat in the shape of miniscule round, grey balls.  If you’re lucky, you’ll find the larval insect that produced this scat.  Chances are, according to Charley Eisman, author of Tracks and Sign of Insects, that many of the resident insects are in the Gelechioidea family of moths.  The larvae of these moths are consumers of Staghorn Sumac seeds, and judging from the amount of scat usually present, they spend a considerable amount of time inhabiting the seed heads.  It’s likely that Black-capped Chickadees and other birds you see gleaning sumac fruit are actually there  for the larvae as much as the seeds.

 

 


Hophornbeam Fruit

 The fruits of the Hophornbeam tree (Ostrya virginiana), also known as Ironwood for its strong,hard wood, are drooping clusters of papery, bladder-like sacs each containing a nutlet. The “hop” portion of its name refers to the resemblance of its fruits to those of true hops that are used in the production of beer. Hornbeam refers to a related European tree whose wood was used to yoke oxen; therefore, its American counterpart wood was also used as a “beam” with which to yoke “horned” beasts of burden.
