  Pine siskin 
    Spinus sinus
  • The Pine siskin is a wide-spread, gregarious bird that often frequents our area in the winter, as it spends much of its time breeding in the coniferous forests of Canada and the northern United States.
  • It forms large flocks during the nonbreeding season and is commonly attracted to seed feeders. This nomadic finch ranges widely and erratically across the continent each winter in response to the presence of seed crops.
  • These brown-streaked acrobats flash yellow wing markings as they flutter while feeding or as they explode as a group into flight. They are better suited to clinging branch tips than to hopping along the ground.

  •  When cold night temperatures plunge far below zero, they can increase their metabolic rates 40% higher than other songbirds their size.   They can also increase their winter fat 50% more than their Goldfinch relatives.
  •  The oldest Pine siskin was identified to be at least 8 years, 8 months old when it was found in Michigan in 1966, having been banded in Pennsylvania in 1958.

White -Throated Sparrow
Zonotrichia albicollis

This common winter bird of eastern woodlots, is often found scratching on the ground in small numbers, near bird feeders that are placed close enough to sheltered areas.

They return to northern forests in the spring to sing their clear whistles of ‘Oh-sweet-canada’ and  find a mate. 

Adults may have head stripes of either white or tan, and scientists have found some odd differences in behavior between these two color morphs. Interestingly, they almost always mate with the opposite color morph.

Crisp facial markings make the White-throated Sparrow an attractive winter visitor. There’s the black eyestripe, the white or tan striped crown, the yellow lores-the region between the eye and bill on the side of a bird's head -and the white throat bordered by a black whisker, or malar stripe.

These sparrows readily visit feeders or fallen seeds beneath them.  They feed on millet as well as sunflower seeds.  If you make a brush pile in your yard it will give White-throated Sparrows a place to take cover in between trips out into your yard.

Chicken of the Woods Mushroom
Laetiporus sulphureus



Chicken of the Woods is a summer and fall mushroom you might find in our local woods this time of year.  It is a common northeast fungus that is often found in clusters, but occasionally is solitary. It is usually bright orange, but can be more reddish or yellow depending on age and often lightening up in color at the edges.


It is said to be an edible mushroom and a fine chicken substitute as long as you make sure to fully cook the mushroom. But be wary of those that grow on conifers, as they are a different species that can cause poisoning. A good tree can yield 50 pounds of mushrooms.

Chicken of the Woods grows in trees that are either living or  decaying and cause a reddish brown heart-rot of the wood. This  destabilizes the tree by hollowing out its center.

Historically, the former wooden ships of the British Naval Fleet were known to be damaged 
by this fungus.

Northern Water Snake       
Nerodia sipedon

    All Photos by Debbie Satorius

·       Averaging at an adult length of 2-4’, this a common snake in Maryland that frequents ponds, streams, lakes and most any wetland habitat.
·       Females are larger than males. Young snakes are born alive from July to September. The litter ranges in size from 4 to 99 offspring. Larger females tend to have larger litters.
·       These snakes are not venomous, but are often mistaken for copperheads or cottonmouths due to their markings.
·       Their colors vary greatly in appearance from gray, tan, buff or brown.  Colors are more vivid in young and wet snakes.
·       They have no heat sensing pits like venomous snakes, their pupils are round  and  their heads are narrow and oval.
·        When threatened they can flatten their bodies and begin to strike and bite furiously while emitting a foul smelling musk.
·        Producing a protein in their saliva that is an anti-coagulant, they can bite and follow the trail of blood to their wounded prey.







 Skunk Cabbage  
Symplocarpus foetidus


·       A moisture loving forest ephemeral
·       More closely related to Jack-in-the-pulpit than cabbage
·       It gets its name from the pungent odor it gives off when 
      any part of the plant is  broken or damaged
·       Flowers in the winter before leaves emerge, attracting 
      gnats and flies that pollinate the flowers and take 
      refuge within the flower structure. Often flowers 
      in February.
·       Food for snails and slugs as well as ruby tiger 
      moth and cattail borer moth caterpillars
·       Contain crystals of calcium oxalate, making them toxic 
      to most animals, yet hungry snapping turtles and 
      bears have been seen eating the leaves in spring
