Roanoke Logperch (Percina rex)

 Article by Ed Coleman, Virginia Master Naturalist, Southwestern Piedmont 

On April 1, 2024, the U.S. Fish and Wildlife Service announced a proposal to remove the Roanoke Logperch (Percina rex) from the Federal List of Endangered and Threatened Wildlife.  In the proposal, the U.S. Fish and Wildlife Service stated that "threats to the Roanoke logperch have been eliminated or reduced to the point that the species no longer meets the definition of an endangered or a threatened species under the Endangered Species Act of 1973." The federal agency has determined that this large freshwater darter is no longer at risk of extinction as populations are shown to be stable or expanding and reproducing. When the Roanoke logperch was added to the federal list in 1989, they were found in only 14 streams in Virginia, compared with a 2019 survey which found the species in 31 streams in Virginia and North Carolina.  

Success for the comeback is attributed to aquatic-restoration projects, removal of artificial barriers such as dams that isolated populations, and the creation of fish passageways.  The end result has connected hundreds of miles of habitat allowing fish from one population to move to another, thereby expanding genetic diversity as well. Even so, the geographic range of the Roanoke Logperch is still very limited, endemic only to the southern Piedmont of Virginia and northern North Carolina.  The species is found in larger streams in the upper Roanoke, Smith, Pigg, Otter, and Nottoway River systems and Goose Creek in Virginia and in the Dan, Mayo, and Smith River systems and Big Beaver Island Creek in North Carolina.

While Percina rex may be considered the "king" of freshwater darters, because of its size relative to the other ten members in the Percina genus, this small fish only grows up to six inches in length.  Other identifying characteristics described by the Virginia Department of Wildlife Resources include having a moderately long, pig-like snout, round or vertically elongate lateral blotches on its body, strongly patterned fins, and a marginate or truncated tail fin. During the breeding season, the dorsal fins and spots on mature males turn bright orange.

Like most darters, the Roanoke Logperch lives on the bottom of streams and rivers, preferring clear, swift water with rocky or sandy substrate.  Large pectoral fins help them stay low in the water as they skim across the bottom feeding on benthic macroinvertebrates such as mayflies, caddisflies, and stoneflies or their larvae.  They actively hunt using their elongated snouts to flip over small pebbles at the bottom of rivers and streams to expose prey.   Roanoke Logperch also spawn in clear, swift currents, however, fertilized eggs usually float downstream to be deposited among the slower-moving shallow pools near the water’s edge. 

Delisting a species from the Federal List of Endangered and Threatened Wildlife is always a cause for celebration.  For the Roanoke Logperch, it has taken 35 years to reach this status at a cost that would be near impossible to estimate.  But the lessons learned along the way have been invaluable.  Simply put, dams without fish passageways isolate fish populations and trash, chemicals, and excessive sediment in the waterways destroy fish and their habitats.  There are four other federally listed endangered fish in Virginia and 24 species of fish listed as either threatened or endangered by the Virginia Department of Wildlife Resources.  As Master Naturalists, we can make a difference for the remaining endangered and threatened fish in Virginia by volunteering for riparian buffer cleanups and teaching our friends and neighbors about the environmental benefits of maintaining vegetated buffers along streams sides.

A word of caution, while the U.S. Fish and Wildlife Service has proposed to delist the Roanoke Logperch from the Federal list of Endangered and Threatened Wildlife, the fish is listed as threatened or endangered by the Virginia Department of Wildlife Resources as well as the North Carolina Wildlife Resources Commission.   It is illegal to target Roanoke Logperch by angling. It is a violation of state and federal law to harass, harm, or take any Roanoke Logperch.

Pollinator Week 2024

I have been working with European honey bees for almost 13 years now. Some of the things that I love the most are the challenges that present themselves. The dramas of the hive such as queens attacking their sisters, would be invaders being stung to death and then mummified, and the pushing out of the male bees at the onset of the winter for them to starve death are all fascinating. And of course, the sweet, sweet, honey reward. Of course, European honey bees are not native to the United States nor are they even close to our only pollinators. The first hive was brought over on the Mayflower and later spread throughout North America being called the ‘white man’s flies’ by the indigenous communities. 

Virginia is home to over 450 native bees that have co-evolved with our native plants tocontribute greatly to their pollination. They are for the most part not social like honeybees and have a wide range of interesting ways to raise their young independently witheach female making their own nests for their developing brood. Some bees dig holes inthe ground and line their nests with leaves or make a cellophane like substance. Othersuse hollow stems or burrows in logs, and bumble bees re-purpose old mouse burrows.They come in different sizes and colors ranging from bright metallics like the Sweat Beeto dull oranges, browns, and blacks like the Two-spotter Longhorn Bee. Perdita minimais the tiniest bee at only 2 mm in length and our biggest coming in at almost an inch, arethe Common Bumble Bees. None of our native bees make honey, only small packets offood for their young. But they make better pollinators than honey bees for the most partas they have evolved with the native flowers and have different length tongues and have different strategies, like the bumblebee who uses buzz pollination to shake the pollen out of flowers. But wait! You’re sitting and looking at your beautiful ox-eye daisies and you notice something that does not have the body shape of a bee…. Wasps, beetles, moths, butterflies, flies, and even birds pollinate flowers while trying to grab either that sugar fueled nectar reward, using the flower as a base to prowl and eat other insects, or by grabbing up some protein rich pollen. The stink horn cabbage’s bloom smells like rotten meat and blooms in February while the days are still frigid and couldn’t be pollinated by anything other than flies! Scientists are still trying to scout out and count the most likely thousands of pollinators other than bees. I believe I sometimes count as a pollinator as I walk through fields during the summer, brushing past flowers, eventually being covered in yellow from the head down. 

Without this network of a mostly invertebrate, flower loving community, we would be doomed to a life without 75% of our fruits, nuts and vegetables. Over 100 crops in the United States alone depending on pollination. And yet, in a short 5-year study (2008-2013), wild bees declined by 23% across the United States. All over the world, scientists are reporting staggering decline in insect numbers in general. Habitat loss, climate change, and pesticide use are all slowly working against these small but mighty beasts that keep our species going. Although one person, one garden can not reverse what is occurring in our ecosystem, we can do some things that combined, may be the literal life and death of a localized community of insects in your area. Planting native plants of all kinds that bloom at different times of the year allows access to food for these insects during all seasons. Reduce or eliminate pesticide use around your garden. Build brush piles and leave some areas wild. Additionally turning off your outside lights when you go to bed can reduce confusion for night flying insects. There are also a few citizen science projects that are already approved like Budburst and Bumblebee Watch to help count and monitor pollinators so scientists can monitor the changes and declines of our important insects. Either way, go out, find a flower or two, and sit in amazement as something so small that contributes something so important to us all!

Recent Herp Sightings at the Fell Residence

Not a day goes by at my place without a visit from some interesting wildlife!  
Here are some recent visitors from this spring...

This tiny guy must be one of this year's hatchlings.

Amphibian Spring - Love In The Rain

By Brian Williams and Dr. Ariana Kuhn 

"It’s February, it’s dark, it’s raining – lets go!”   

While most humans may prefer a warm fire, a glass of wine, and a Valentine’s dinner, herpetologists are pulling on wading boots and rain gear, strapping on headlamps. and heading to the ditches and vernal pools with nets and cameras. So if you see some crazy folks wandering around in the woods on a rainy February night, don’t worry. It's just your local “herpers” out trying to catch the annual nuptial dance of the spotted salamander (Ambystoma maculatum).

The “Liebespiel” only takes place over a few nights in February and you have to be at the right place at the right time to see these magnificent spotted miracles performing their dance. Even if you don’t see the mating ritual, you might still be lucky enough to catch sight of a few of these impressive salamanders with two rows of bright yellow spots along their backs. Every spring, they migrate from the forest to wetland ditches and vernal pools to breed. Males usually arrive first, dropping spermatophores on small underwater vegetation where females will take these packets into their cloacas to fertilize their eggs and redeposit them on the vegetation in a sticky gelatinous mass. Each mass contains 100 to 200 eggs. The egg masses are quite easy to see, clinging to the underwater twigs with little black dots inside each egg sack (often seen together, wood frog egg masses and other salamander masses can look similar). The adults leave the pool after a few days, leaving their eggs behind. The larval salamanders hatch within a month or two and become salamanders in two to four months. The vernal pools are ideal sanctuaries for these eggs and larvae to grow, as they contain no fish predators. The best pools have lots of scuds and other macro invertebrates that the larvae feed on before they metamorphose, loose their gills, and begin the next part of their adult lives on land.

The first week of February saw major rains and it was evident by the road kills that the amphibians were taking advantage of the water levels in the ephemeral pools. Although we could not get out on this first rainfall event, several nights later we did manage to check out several locations and find not only spotted salamanders, but a few of the other amphibian harbingers of spring. The spring peeper (Pseudacris crucifer) is the call that most will recognize, sometimes you can even hear it through the rolled-up windows of your car as you pass by low lying areas with standing water. But this time of year you can also hear the raspy plunk of the wood frog (Lithobates sylvaticus), the resonating croak of green frog (Lithobates clamitans), and the cricket-like trill of the upland chorus frog (Pseudacris feriarum). The eatsern newt (Notophthalmus viridescens) are also common in some of these same locations this time of year, as they are doing their own underwater courtship dance.

Such a brief moment in time between egg deposition and when these “wetland wonders” head back underground for another year. They can live up to 20 years and return to the same pools each year, so it is important that we protect these sensitive areas.

Participating in early spring identification and monitoring of aquatic systems that support vernal breeding amphibians is a valuable resource to conservation, research, and ecosystem health. This data not only helps reinforce accurate geographic ranges and environmental preference of species, but also key information about the timing of biological events, such as breeding and development. Over time, threats like climate change could cause major shifts in these events, which could have serious implications for sensitive amphibians. Additionally, mapping out areas that are essential to many vernal breeders can benefit conservation and restoration projects that provide critical habitat to some of our less frequently seen, but incredible native species, like the spotted salamander.

Every Birder Loves a Sharp-dressed Man: Meet the Dark-eyed Junco (Junco hyemalis)

 By: Christine Stewart

My first encounter with the Dark-eyed Junco was last winter. He was a new arrival to

our yard, which was home to bluebirds, cardinals, tufted titmice, and various other

sparrows, finches, and wrens. I was perplexed because I didn't expect to find a new

bird settling in during the dead of winter.

Image from: https://s3.animalia.bio/animals/photos/full/original/dark-eyed-junco-3.webp

I soon was enamored with this little man. His coloring made him look like he was

sporting a tuxedo…..charcoal on top and a white belly. His wings and tail were sharply

delineated black and white stripes resembling a cumberband. Dark-eyed juncos are a

medium-sized member of the sparrow family, Passeridae, with a rounded head and jet

black eyes. Their bill is short and stout and conversely their tail is relatively long for

their body size. The males are the “sharp-dressed men” and the females are

drab….usually paler gray or brown on top. But this description is for the “typical”

population; the coloration of the species varies widely throughout the populations across

North America. For example, there is a population out West with a pink-tinge to their

feathery wardrobe.

As I continued to observe my new friend scrounging for leftovers under the bird feeder, I

noticed they hopped rather than walked along the ground. He would scratch among the

leaf litter and literally fling it into the air like a juggler. He then proceeded a little further

back into the woodland edge and scrambled among the leaf litter and brush piles.

Searching for food or maybe a place to nest? Dark-eyed Juncos are ground foragers

and nesters.

Their nests are entirely constructed by the female made from nearby materials…leaves,

twigs, moss, animal hair, etc. They are about 3-5” in diameter and tucked into brush,

leaf litter, and even upturned tree roots. They have 2-3 nests a season each holding

3-6 eggs at a time. The young leave the nest 9-13 days after hatching.

During nesting, Dark-eyed Juncos incorporate a larger amount of insects into their diet,

such as caterpillars, butterflies, moths, ants, wasps, and flies. But the remainder of the

year they are primarily 75% seed-eaters. At feeders they are scavenging the leftover

millet, cracked corn, and black-oil sunflowers left on the ground. Without human

support, they dine on weed seeds like ragweed, crabgrass, chickweed, sorrel, and

lamb’s quarters. They are even known to burrow in the snow in search of seed. So

perhaps we need to reconsider the “weeding” of our gardens.

These “snowbirds” typically migrate from Canada to the Lower 48 for the winter, except

for the Appalchian population. They are vertical migrators descending down from the

spruce-fir forests in the higher elevations to the foothills in woodland edges or brushy

thickets. They live in flocks, often with other sparrows and bluebirds in an area roughly

10 acres during their winter stay.

According to E-bird, they are typically seen in Martinsville between mid-October through

mid-April. For this season they were last-sighted at J. Frank Wilson Park on November

5th. The high count so far this year was on January 28th at Community Park where 35

Dark-eyed Juncos were observed. And a study conducted by USA Today, reports that

Dark-eyed Juncos rank #7 of sighted birds during November in the state of Virginia.

So now that winter will soon be knocking at our doors, look for the “sharp-dressed man”

in your walks along the Dick & Willie Trail (particularly off Spruce Street) or even in your

own yard.

Milestone Reached on VBWT Rock Castle Gorge Trail

 Submitted by Dottie Haley

Chapter member Garnett Hudson recently reached a personal milestone on one of our local Virginia Birding and Wildlife Trails.  Garnett graduated and certified as a SWPVMN in 2022.  He frequently visits many of our local trails but he established a long-term goal 25 years ago regarding his Rock Castle Trail hikes.  This journey began as a competition between him and his younger brother to see who could be the first to complete 100 hikes at Rock Castle.  Untimely surgery for Garnett allowed his brother to win but it was then that he set a new personal goal - 300 hikes over his lifetime.   Though his time to complete the walk has gotten a little longer over the years, he adjusted and held tight to his goal.  On November 15, 2023, he completed number 300.  And did I forget to mention that Garnett will celebrate his 78^th birthday this coming February?  Quite inspiring!

 

Photo by Dottie Haley: Progress was documented by making marks on his walking stick after each hike.  It took him four different sticks to record all 300.

He chose Rock Castle as his course due to its likeness to the Appalachian Trail.  Garnett always had a desire to complete the Appalachian Trail hike and although he has not completed it in its entirety, he has walked over 100 miles of the trail including three separate overnight stays. Rock Castle is a difficult 10.8-mile loop hike on the Sweet Mountain Laurel loop of the Virginia Birding and Wildlife Trails.  The terrain is rough and rocky and often quite steep.  Elevation during the hike spans 164 floors and requires around 27,000 steps to complete.  The scenery is diverse and includes deep woods alongside the rushing creek, tall rock formations and open pastures where you will need to watch your step to avoid the fresh cow piles.  Seasonal conditions add to complexity of the hike.  Fallen leaves, acorns and disguised patches of frozen ground are possible during the winter.  Garnett ended up making two trips to the ER over the years after hikes during which he suffered a fall.

His most memorable walks were those where he had unique wildlife encounters.  He was able to watch an Otter catch and eat a fish.  Although it happened too quickly to get a picture, it was a once in a lifetime encounter.  During another hike, he observed a bear cub high up in a tree bellowing for his mother.  Knowing she would answer the call, he quickly moved on.

When I inquired as to whether he would continue his walks now that his goal has been met, the answer was yes, but probably not as frequently.  I was curious as to whether becoming a VMN had impacted his hikes.  He commented that since becoming a VMN, he is more aware of litter that he sees on the trail and now picks it up as he goes.  He also now enjoys using the Merlin app to help identify birds.  He uses it when he walks but also enjoys birding from his deck at home.  He has used the app to identify as many as 27 different bird species in his backyard.  

There is nothing better than a walk in the woods on a nice day.  If Rock Castle doesn’t sound like the trail for you, we are blessed to have a wide variety of trails in our area to choose from.

National Bat Week

 by Regina Flora

SWP’s Education Outreach Committee celebrated National Bat Week by exhibiting on bats at the Bonez and Booz festival hosted by VMNH on October 28th. Nine chapter members presented bat facts, discussed differences between bats and birds, and exhibited bat specimens and a bat house. A local bat enthusiast, Amanda Rhyne, provided answers to questions and a display board of information.

Children in their fun festival costumes participated by drawing bats with walnut husk stain. A bat cutout was distributed for continued learning at home. About 500 children and parents received information at the table. 

We have 17 species of bats in Virginia. All of our bats feed on thousands of insects each night. Some are tree bats and overwinter in tree cavities, wood piles, leaves and loose rocks. Other types form large colonies for hibernation inside caves and old mines. 

Although not blind, bats rely on echolocation since they are nocturnal. They emit  sound waves which bounce off objects and return as an echo. This echolocation allows them to navigate, find prey, and communicate. 

To encourage bat populations in your backyard, grow native plants, provide a water source, avoid pesticides, and allow leaves and old snags to stay in place for shelter. You can also provide shelter by placing a bat house.
