Happy Thanksgiving

(I'm feeling a bit guilty that we celebrate giving thanks by eating such a grand bird.)

EASTERN WILD TURKEY

(Meleagris gallopavo silvestris)

I just bought my Thanksgiving turkey, a domesticated turkey found on most of our plates this time of year.  The wild turkey is also pervasive -- it can be found in 49 states including Hawaii. The subspecies in our area, the Eastern wild turkey was called the “forest turkey” by the Puritans. This turkey can be found from the Canadian border to northern Florida and westward to the Mississippi River.  There is a distinct brown-tipped upper tail feather found on the male of the Eastern wild turkey. Their preferred habitat is typically wet, swampy land, or early-growth forests with low-lying brush.  We sometimes hear wild turkeys calling in the woods near us though it's more common to see the unrelated turkey vulture.   -- Merikay

Atlantic sturgeon

Atlantic sturgeon  can grow to 14 feet long and weigh 800 pounds.  These ancient fish have been nearly exterminated -- only about 200 are known to survive in the Chesapeake Bay region.  Thanks to efforts by researchers and others, there is some hope of rebuilding their populations though recent cuts at the EPA may jeopardize years of progress.  I'm posting this in November and you might consider sharing with your family the history below as we remember the early colonists at Thanksgiving.

More than two thirds of the 214 settlers at Jamestown died in the harsh winter of 1609, during what they called the “starving time."

In the spring, the survivors saw something miraculous surging up the river: an armada of dinosaur fish, massive as logs, with bony armor, forked tails, sloped heads, and dangling whiskers. They were Atlantic sturgeon, returning up the James River to spawn.  They could wade into the river and spear huge fish with their swords, thus saving their colony from starvation.

Sturgeon are sometimes described as the “foundation fish," because they allowed the English to keep their tentative toehold in the New World.  Now we have taken them to the brink of extinction.

cricket frogs

Julie Magnin took this photo of a southern cricket frog at the Caw Caw Interpretive Center in Ravenel, South Carolina.  Highly variable, even within a single puddle, cricket frogs (northern and southern) can usually be identified by the backwards-pointing triangle on top of the head and often have a contrasting stripe down the back. carolinanature.org

The photos below of a northern cricket frog shows the distinct yet variable markings.  The northern cricket frog is one of 14 species of frog and toads found in Montgomery County.  Learn more including how you can become a citizen scientist to study frogs in a spot near you as part of FrogWatch.   Photo on the left is from Montgomery County, the one on the right was photographed in Tennessee (www.leaps.ms).

Virginia has a great website on frogs and toads as well as salamanders, lizards, snakes and turtles:  Since this post started with a very small frog, here are some other similarly small frogs which might help you to ID your next tiny frog.

Bog turtle

At only about 4 inches long, the bog turtle (Glyptemys muhlenbergii) is North America's smallest turtle.  It's also listed as a federally threatened species. Though rare it can be found in the Chesapeake Bay region.

This species typically shows a bright yellow, orange or red blotch on each side of the head. The nearly parallel sides of the upper shell—known as its carapace—give bog turtles an oblong appearance when viewed from above. These small, semi-aquatic turtles consume a varied diet of primarily insects, snails and worms.

Bog turtles usually occur in small, discrete populations, generally occupying open-canopy, unpolluted, herbaceous sedge meadows and fens bordered by wooded areas.  Bog turtles depend upon this diversity of habitats for foraging, nesting, basking and hibernating.

The northern population of bog turtles ranges from New York and western Massachusetts south to Maryland.

The greatest threats to the bog turtle are the loss, degradation and fragmentation of its habitat. The species is also threatened by poaching for illegal wildlife trade.

In the Chesapeake Bay region the US Fish & Wildlife Service works to protect the bog turtle:

  • Biologists are using goats to maintain wetlands through managed grazing. For a few months in 2008, 19 goats were placed on a 5-acre bog turtle site in Carroll County to control unwanted vegetation, including the invasive multiflora rose.
  • Additional projects through the Coastal Program and the Endangered Species Program with private landowners and other partners include:
    • Installing fences on 6 acres at two sites in Maryland and a 3-acre site in Delaware to protect these sites from overgrazing.
    • Working with a Maryland landowner and USDA-NRCS to protect 30 acres of bog turtle habitat through the Wetland Restoration Program.
    • Prioritizing 65 bog turtle sites in Maryland for future restoration efforts based on population size, reproduction and connectivity to other bog turtle sites.

Is there anyone interested in researching what we at Earth Stewardship East can do for the bog turtle?  If so, contact Merikay at merikays@verizon.net.

Hickory Horned Devil

Earth steward Taylor Knight photographed this hickory horned devil on Van Deventer Island in the Potomac.  This gorgeous caterpillar can be found throughout our region, generally as it drops to the ground looking for a place to pupate.  It is one of the largest native caterpillars -- can get as big as a hot dog!  Not surprisingly, it becomes a very large moth -- the regal moth with up to a 6 inch wing span.  Native trees are its food source:  walnut, hickory, persimmon and others.

Eastern Box Turtle

Eastern box turtle were once very commonly found throughout our region.  Near the University of Delaware is a 40 acre woodlot which has been left undeveloped and undisturbed.  In 1968 a biologist surveyed the woodlot and found 91 eastern box turtles.  Using the same technique, subsequent counts have followed the population with 22 turtles in 2002 and only 12 in 2012.  Dr. Tallamy of UD projects that there will be none left at the next counting.  If that is the fate in a contiguous 40 "natural" acres, it is possible to project decreased numbers in areas with habitat fragmentation, roads, lawns, and development.  Female turtles need areas in which to lay eggs -- turf grass areas will not do.  

After hearing a talk by Dr. Tallamy I replaced large areas of our lawn with areas planted in native trees, shrubs and perennials.  Within a few years I found turtles nesting in my garden!  I don't see the turtles often, but occasionally as I'm in the garden I will see one slipping back under plant cover.   I sometimes see them at my garden pond.  Sadly, as is too often the case I found one crushed by a vehicle on the road near our house.  I don't know what the fate will be for the eastern box turtle, but this is one example of how our landscaping choices can make a difference.  With so much working against their survival, it seems the least we can do is replace lawns with habitat that offers the possibility of creating new generations. -- Merikay

Blue Dasher Dragonfly

Common through out the United States and up into Southern Canada, these brilliant dragonflies can be spotted by ponds, lakes, marshes, and bogs. Larvae are very tolerant of wetlands with poor water quality and low dissolved-oxygen levels. Males are a brilliant blue as pictured. Females are more yellow brown.   I was able to watch a female visit the pond and lay eggs on the lily pads.  Photo below by Terri Pitts, local Master Gardener.

 

Our Native Bees

I love watching the native bees in my garden (click to advance photos above).  Spend a bit of time outside and see how many different bees you can find.  Take this challenge, find 5 different species of native bees in your garden or neighborhood.  If you want, send us a photo.

There are 4,000 species of native North American bees from tiny Perdita to large carpenter bees: all pollinator flowers, especially native flowers.  The European honey bee, remarkable as it is, doesn’t know how to pollinate a tomato, pumpkins, watermelons, blueberries or an eggplant flower, while some native bees are masters at this. 

Native bees come in a wide range of sizes,shapes, life styles, places they frequent, nests they build, flowers they visit and season of activity.  For instance, the Southeastern blueberry bee is capable of visiting as many as 50,000 blueberry flowers in her short life.

Bees are descended from wasps. Most wasps are carnivores.  Millions of years ago, when the first flowering plants began to bloom, some wasps made a switch from hunting prey to gathering pollen for their brood. Gathering pollen and nectar requires certain adaptations different from those of hunters; so they started to change to meet these requirements and consequently became bees.  

Many of our native bees are ground nesters. They choose a bare spot, with sunshine and start digging. They build a long tunnel slightly wider than their own bodies. Some don’t want any neighbors around; others prefer the company of their own sisters.  They are solitary in the sense that each digs her own nest and takes care of her own brood all by herself. Others show different levels of cooperation, sharing the tasks of nest building and food provisioning.  At the end of the tunnel the mother bee builds a chamber a little wider; this will be the nursery for just one bee. She fills it up with enough food for one bee to grow from egg to full size. There she lays an egg and seals the chamber. She will add other branches to the tunnel; at the end of each there will be another cell or chamber properly stocked and with an egg.

Some bees take advantage of already existing holes -- hollow stems or holes made by beetles or others in trees. There, they construct chambers, usually lined up in a row, which they stock one by one to serve as nurseries.  Native mason bees are hole nesters who use clay to build walls between cells and to seal the entrance. Leafcutters cut round pieces of leaves for the same purpose and also to line the inner walls of the tube.

An excellent book on our native bees recommended by the Xerces Society ( xerces.org ) is The Bees in Your Backyard:  A Guide To North America's Bees by Joseph S. Wilson and Olivia Messinger Carril (Princeton, 2015).  Below are some native bees in Merikay's garden.
