Giving Thanks For Naturally Curious Readers

11-26-15 Otis Sumner Brown IMG_5841 I would like to devote this Thanksgiving post to expressing my heartfelt appreciation to all of my readers – those who take the time out of very busy days to read my posts, those who participate in Mystery Photo challenges, those who share my blog with others, those who use it to foster a love of the natural world with youngsters, and those who have chosen to support my blog through a donation. You have all been so generous, and your generosity has allowed me to focus on the work I am so passionate about. Thank you for valuing and supporting this blog – hopefully in some small way it contributes to fostering an awareness of and concern for all things natural, especially in younger generations.

Black Cherry – well known to most readers!

black cherry tree silhouette IMG_5114Black Cherry, more than most tree species, often has several identifying features even after it loses its leaves. The buds of Black Cherry have about ten scales, each of which is brown at the tip and green at the base. The bark of young Black Cherry trees is typically smooth, reddish in color and covered with grayish, horizontal lines called lenticels — small openings that allow the passage of gases in and out of the tree. The bark on older Black Cherry trees consists of squarish scales, curved outward at their vertical edges, somewhat resembling burnt potato chips. Black Cherry is one of several trees on which the fungus Apiosporina morbosa causes Black Knot Galls. Lastly, Black Cherry is the primary host for the Eastern Tent Caterpillar moth. These moths encircle Black Cherry branches with their egg masses, and the eggs hatch just as Black Cherry’s leaves emerge from their buds, providing food for the young larvae.

Bird Nests: Look But Don’t Collect

11-23-15 mourning dove nest2  005It is prime time to look for bird nests now that leaves have fallen and heavy winter snow has not arrived. Nests such as this Mourning Dove nest are visible and still in fairly good condition. Much can be learned from examining the habitat, exact location, size, shape and construction material of these avian nurseries. But the nests must be left where they are, for possession of not only a bird, but of a bird nest, egg or feather of most migratory birds, even for scientific research or education, is illegal if you do not have a Federal Migratory Bird Scientific Collecting Permit.

Ninety-seven years ago the Migratory Bird Treaty Act (MBTA), one of our oldest wildlife protection laws, was created. Basically it is a law that protects birds from people. It was made in response to the extinction or near-extinction of a number of bird species that were hunted either for sport or for their feathers. According to the United States Fish & Wildlife Service (USFWS), “The MBTA provides that it is unlawful to pursue, hunt, take, capture, kill, possess, sell, purchase, barter, import, export, or transport any migratory bird, or any part, nest, or egg or any such bird, unless authorized under a permit issued by the Secretary of the Interior.” A list of the species this law pertains to can be seen at

Not all North American bird species are protected under the MBTA. (Passenger Pigeons were not protected, and they no longer exist.) Birds that are considered non-native species such as the House Sparrow and the European Starling are not protected, and many hunted or game birds, including ducks, geese, doves, and many shorebirds are subject to limited protection and can be hunted in season.

The U.S. Fish and Wildlife Service is currently working on strengthening this bill to better protect birds from modern-day threats (windmills, cell phone towers, etc.). According to USFWS estimates, power lines kill up to 175 million birds a year. Communications towers account for up to 50 million kills, and uncovered oil waste pits account for up to another 500,000 to 1 million deaths. Data on wind turbines are harder to come by, but current estimates are around 300,000 bird fatalities a year. A number of companies in the oil and power-line sectors have already developed and implemented best practices to protect birds. Let us hope that this trend continues.

Fishers Eating Fruit & Marking Territory

11-20-15 fisher scat 134When one thinks of fishers, meat-eating predators come to mind. While it is true that the fisher is a generalist, opportunistic hunter and scavenger, and feeds on any prey it can catch and kill (snowshoe hares, rabbits, squirrels and other small rodents, birds, bird eggs, smaller weasels, shrews, porcupines, raccoons, amphibians, reptiles, carrion and a very occasional cat or chicken), it also consumes fruit and nuts, especially when prey is scarce.

Given the amount of apples that are available this fall, even if prey isn’t hard to find, it is not too surprising to see fisher scat composed solely of apples at the base of this scent marking post (confirmed by fine fisher hairs at the very tip of the stump as well as scat).

Thimbleweed Seeds Dispersing

11-9-15 thimbleweed 087Often Thimbleweed (Anemone virginiana) is overlooked when its white flowers are blooming during the summer, but its seed head is rarely missed in the fall. When flowering, stamens surround a green cone that elongates into a cylindrical fruit twice as long as it is wide, giving this member of the Buttercup family its name. The seeds mature in the fall, and the style, part of the female reproductive structure that remains attached to the developing seed, develops a woolly texture, turning the “thimble” into a ball of fluff. A close look reveals that this “cottonball” consists of many tiny dark seeds, each of which bears a cottony tuft to enhance its dispersal by the wind.

Thimbleweed produces chemicals which inhibit seed germination and seedling growth in many species of plants, so often the ground is relatively bare around this plant. Mammalian herbivores usually leave Thimbleweed alone because the foliage contains a blistering agent that can irritate the mouth parts and digestive tract.

Red Squirrels Winter-proofing Nests

11-18-15 red squirrel2  032Red Squirrels are active year round and have nests that they can retreat to at any time of the year. These nests are used for shelter and rest, for over-wintering and as brood chambers. Red Squirrels build them in a variety of spots (tree cavities, old woodpecker holes, middens, rock piles, rotting logs, tree canopies) with a variety of material (twigs, branches, leaves, shredded grape bark, etc.).

Regardless of where they build their nest or what they build it with, Red Squirrels line it with fine, relatively soft material, such as grasses, bark fibers, feathers and fur. If a Red Squirrel happens upon potential nest-lining material, including an old dog towel hung out to dry, it will readily chew it into shreds and carry them back to its nest.
