In Canada, they celebrate National Beaver Day on the last Friday in February but here in the US, it’s celebrated on April 7th.

Here’s a wonderful YouTube video done by the BBC that has great footage of dam building and other activity. :

If there are human/beaver conflicts going on near you – the beavers don’t need to be evicted. 

There are all sorts of solutions to protect trees and even address any unwanted flooding from dam activities. Check out our Beaver Solutions page for a video.

Here are some fun beaver facts that you can use to amaze your friends:

- Beavers are the second largest rodent in the world
- Beavers mate for life
- Dams made by Beavers prevent flooding disasters and create valuable wetland habitats
- Beavers live in suburban settings wherever there is flowing water like creeks, streams, rivers

Here’s a short video telling about our Virginia Opossum:

Here’s an exciting sighting from Joe Coleman from last week.  What a great encounter!

From Joe:

A Long-tailed Weasel with a bad case of mange on its rump just walked through the woods in front of our house. 

At one point it pursued a squirrel up a tree but didn’t catch it.  Unfortunately, I did not have my zoom lens on my camera and it was gone before I was able to change lenses. 

While I’ve seen them around one of my neighbor’s farm ponds (about a 1/4 mile from my house) this is the first weasel I’ve had in the yard.

American Woodcocks are really interesting birds and they have an incredible courtship display.  Here it is described by the experts at Cornell:

He gives repeated “peents” on the ground, often on remaining patches of snow in the early spring. After a time he flies upward in a wide spiral. As he gets higher, his wings start to twitter. After reaching a height of 70-100 m (230-328 ft) the twittering becomes intermittent, and the bird starts chirping as he starts to descend. He comes down in a zig-zag, diving fashion, chirping as he goes. As he comes near the ground he silently lands, near a female if she is present. Then he starts peenting again.

They are classified as shorebirds (like sandpipers) but live in uplands areas, preferring young brushy forests.

Looking at their markings, you’ll notice their amazing camouflage – blending in seamlessly to the forests’ branches, leaves and bark.

Woodcocks are ground nesters so this camouflage is especially important to the females as they raise the young.

Another interesting characteristics is that they have long flexible beaks that allow them to hunt for earthworms (their favorite food) and rough tongues that help them catch their slippery prey.

People do hunt woodcocks.  Through this activity, a number of common names have been given to this bird.  A few of them are: timberdoodle, bogsucker, night partridge, brush snipe, hokumpoke.

Woodcock populations are declining due to habitat loss but we know of a few places in Loudoun where we can enjoy these neat birds and have a field trip lined up if you’d like to join us.  Information is below:

An Evening with Woodcocks — March (date, time, location TBD based on woodcock activity).   Registration Required. A likely spot will be found to witness the incredible courtship display of the Woodcock, one of our most fascinating avian residents. We will watch and listen for the Woodcock’s “peeent,” and once we know they are around, the date, time, and location will be announced. Questions or to register: Sign Up On-lineor contact Laura McGranaghan at lmcgranaghan@loudounwildlife.org.

One of the organizations that we partner with, Audubon Society of Northern Virginia, has a really nice program called Audubon at Home:

http://www.audubonva.org/index.php/audubon-at-home

To help kick off another year of Audubon at Home, ASNV is holding an Audubon at Home Orientation Meeting on Sunday, March 6, from 1:00 – 3:30 PM at the National Wildlife Federation building in Reston (directions available online).

They’ll cover the basics of creating native habitat on your property, getting your habitat certified as a Wildlife Sanctuary, and — for those who want to have even more impact on habitat restoration in our region — how to become an Audubon at Home Ambassador.

Ambassadors play a key role in Audubon at Home by providing on-site guidance to homeowners and other in creating native habitat.

They will be including two new Audubon at Home on-line resources on the website at the end of this month. These will include Top 10 Native Plant Lists for trees, shrubs, wildflowers, deer-resistant wildflowers, and ground covers and a Frequently Asked Questions page.

The Top 10 lists offer native plant recommendations for a range of growing conditions, with a focus on plants that are adaptable to urban/suburban conditions and that provide benefits to wildlife. The Frequently Asked Questions page will address common questions about habitat gardening and related topics.

Contact Cliff Fairweather at 703-438-6025 if you have any questions about the program.

Sharon Kearns posted this a few days ago and I thought it’d be fun to share here as well :

24 turkeys walked up our driveway today to be counted for the GBBC.  This flock has been around all winter but I have never had them so close and was able to get a correct count.

Also had a juvenile Red-headed woodpecker, probably same seen on Christmas Bird count.  It is starting to show just a little color around the neck and is getting lighter on the chest. 

A neighbor reported hearing and seeing woodcock displaying this evening, we are going to look tomorrow. 

Also two Carolina chickadees were really tearing after each other today, with an audience of other chickadees cheering them on Sharon Kearns Leesburg, Va

Did you know…..our eastern Gray Squirrels breed twice a year…once in the winter (December – February) and once in the spring (May – June). 

As we hit the middle of February, the winter brood is being born and in about 7-10 weeks when they are weaned and start to leave the nest, we’ll start to see the little squirrel pups.

The squirrel nest is known as a drey and is located high up in a tree. It’s made of sticks, leaves and soft mosses. Often, squirrels will make a couple of dreys in case something happens.  We witnessed this first hand a few years ago when a tree came down in our neighbor’s yard. Wasting no time at all, we watched the mother squirrel take the babies out of the fallen nest and straight up another tree into another drey.

In the wild, our Gray Squirrels live up to about 12 years of age.

This article is very applicable to us here in Loudoun, not only because we border West Virginia but also because Wood Turtles and other turtle species live in our midst and we should all be aware of the devastating effects of taking turtles out of their natural habitat.

Federal Sting Nets Reptile Trader With 108 North American Wood Turtles in West Virginia

On 3 June 2008, the Virginia Department of Game and Inland Fisheries (DGIF) was contacted by United States Fish and Wildlife (USFWS) officers based in Martinsburg, West Virginia and requested to be on the lookout for the subject of a surveillance operation suspected of harvesting wild turtles from publicly and privately owned land for sale in the pet trade.

At approximately 1:00 PM, a DGIF Conservation Police Officer stopped a white KIA Sedona minivan heading south on Route 81 driven by Michael P. Ellard of Estero, Florida. Mr Ellard is the owner of two reptile wholesale and export businesses in Florida, “Burgundy Reptile Traders” and “Russian Reptiles”. Found in the van (Fig. 1) were 108 North American wood turtles (NAWTs, Glyptemys insculpta) (Fig. 2), 4 Eastern box turtles (Terrapene carolina carolina), and 6 common snapping turtles (Chelydra serpentina).

Mr Ellard was previously convicted of violations in West Virginia and other states involving the illegal harvest of reptiles and was considered by wildlife enforcement officials to be a “person of interest”. Two other men also involved in this case were in the vehicle and apprehended at that time. Both of Mr Ellard’s businesses had previously been in possession of USFWS import/export licenses and held CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) export permits for a number of species.

Mr Ellard pled guilty to these charges on 31 July 2009. Ellard and his associates were charged with violating the Lacey Act for their participation in the illegal capture and transportation of protected reptiles. The Lacey Act prohibits trade in wildlife, fish, and plants that have been illegally taken, possessed, transported, or sold.

Mr Ellard was sentenced in US District Court in Martinsburg, West Virginia, on 10 December 2009 by US District Court Judge John Bailey to serve 1 year of home detention and 5 years of probation and pay $12,000 in restitution. In August 2009, one of Mr Ellard’s associates was sentenced to 5 months in federal prison, 5 months of home detention, and 1 year of supervised probation. The third man has not yet been sentenced due to current incarceration in Florida on unrelated offenses. All 3 men pled guilty to one count under separate plea agreements.

Of the 108 Wood Turtles confiscated, 1 died while in captivity and the remaining 107 were released into the watershed that Mr Ellard had collected them from. The eastern box and snapping turtles were released as well. These animals had an estimated value of $35,000 in US reptile markets and more than ten times that much in Japanese markets.

The USFWS Office in Hadley, Massachusetts, provided background information. Prior to this incident, in November 2008 Mr Ellard pled guilty in North Carolina state court to charges relating to his apprehension by North Carolina Wildlife Enforcement officers while he was commercially harvesting spotted turtles (Clemmys guttata) for later sale in the pet trade. Spotted turtles are a protected species in North Carolina. Mr Ellard was charged with 1)possession of wildlife for sale and 2) taking of a wild animal on a protected wild animal list.
 
At the time of this arrest, Mr Ellard was also in possession of one North American wood turtle
that he indicated he had captured just previously in West Virginia. North American wood turtles are a highly sought after species by reptile collectors in the United States and abroad. According to advertisements on Kingsnake.com turtle classifieds (http://market.kingsnake.com/index.php?cat=39), full grown adult Wood Turtles are frequently sold as breeding pairs in online classifieds for $500–$750. The majority of these are offered without proof that they are captive bred and not wild caught.
 
In Japan, according to a Japanese Wood Turtle auction site  (http://www.dizzypoint.co.jp/showcase/detail/2150), NAWTs have a current value (as of 2 January 2010) of $3,786 dollars each in Tokyo. North American wood turtles were given CITES Appendix II protection in 1992 and are thereby identified as a “species of concern”. These are species that are not necessarily threatened with extinction but may become so unless trade in specimens of such species is subject to strict regulation in order to avoid utilization incompatible with their survival.

International trade in specimens of Appendix II species may be authorized by the granting of an export permit according to the CITES website(http://www.cites.org). CITES permits are issued on a per species basis to sellers; consequently, it is unlikely that a single NAWT opportunistically removed from a stream in New England would end up in Japan the following week.
 
However, at current prices Mr Ellard’s methodical harvest could have been worth several hundred thousand dollars to wholesalers in Japan. Other species such as the Spotted Turtle not covered under the CITES Treaty may be collected by smaller operators, and they show up on Japanese websites in large numbers in the spring, selling for upwards of $3000 for a male and female adult pair. Many of these are scarred, rough looking, and appear wild caught. Some also have what appear to be deep notches filed in their marginal scutes, an indicator that these may have not only been wild-caught, but also involved in population studies prior to their capture as this is often a method used to identify individual turtles (personal communication, Kevin [Matsutaro] Leahy).
 
North American wood turtles occur in the northeastern and upper midwestern United States and portions of Canada. The population of this species is recognized as declining throughout its range. In the latter 19th and early 20th century, this decline was due primarily to habitat loss and fragmentation resulting from agricultural development and expanding urbanization. 
 
Mid to late 20th century population declines are attributed to waterway pollution, increasing road construction, and focused collection by biological supply houses and the pet trade. Since the 1970s, collection for the pet trade has increased significantly. Commercial collectors time their harvest to coincide with the turtles’ emergence from hibernation while they are still congregated in rivers and streams.
 
Collectors in Pennsylvania and New York have harvested several hundred turtles from less than a mile of stream. This has resulted in the extirpation of this species from areas where it used to be prolific. As a result, the distribution is now more discontinuous than it once was, and gene flow has likely been severely impacted in most areas of this species range.
 
Collection for pet trade is the major threat to the survival of wood turtles. Nesting success generally is very low with egg predators taking a heavy toll. The majority of these predators— skunks, raccoons, and opossums—are human-subsidized species that have experienced significant population and range size increases over the last century.
 
One report conservatively estimated egg and hatchling mortality at 98%. Consequently, many populations in areas close to human activity may consist of 80%–85% adults, while remote populations can have populations with significantly more subadults.
 
Reproductive success depends on a high rate of adult survival, long-lived adults that reproduce many times during their lifetime, and the occasional good season when a nest survives.
The combination of late maturity, low reproductive success, and long-lived adults results in a population structure skewed heavily toward adults.

These characteristics combine to delay the detection of population declines and to reduce the ability of small, declining populations to recover. Population biology (late maturity combined with very low annual juvenile recruitment) limits recovery potential and heightens vulnerability to over-collection. Low mobility (e.g., relative to birds) and tendency to home reduce probability of recolonization of decimated populations. These characteristics necessitate early response to indications of decline.

Recovery of North American Wood Turtles to historical levels is highly unlikely because significant habitat has been permanently lost to urban and agricultural development and as the result of habitat fragmentation. According to the Nature Serve comprehensive species report (http://www.natureserve. org/explorer/), if commercial collection was stopped in much of its range, the wood turtle would require little active protection or management to remain secure.

The wild kingdom plays out across our back yards.  Joe Coleman sent this over and since it can be rare to see this, I thought I’d share.  It’s all part of the cycle after all.  Here’s Joe’s story:

I am just getting around to downloading some photos taken in my backyard on Dec 28 of a Cooper’s Hawk catching an adult squirrel. 

I was getting a glass of water at the kitchen sink and looking out the back window when I noticed quite a fight taking place at the base of a holly tree. 

Fortunately my camera was in the house so I was able to grab it & start taking photos.

All of the photos are a bit blurry due to the light and the action which was pretty fast paced but they are still pretty impressive. 

I remember how skeptical people have been whenever we’d tell stories of Cooper’s Hawks catching squirrels(remember John Drummond’s)  - well they do.  

After these photos were taken, the hawk, with a great deal of effort and with its wings fully extended, managed to drag the squirrel about 30′ over to some briars where it spent several hours on it.  

The other birds and squirrels in the yard came out to visit the feeders during these hours while keeping a careful eye on the hawk.

So why do some folks smirk at Squirrel Appreciation day but then gin up all this hullabaloo over Groundhog day? Go figure….they’re both neat animals and I’m glad we celebrate them!

Groundhogs are also known as woodchucks (even though they don’t chuck wood). They’re great at digging at create really neat underground habitats with different entrances and exits and underground rooms. Here’s a nice video on groundhog life and times:

httpv://www.youtube.com/watch?v=ZheMY_UppW4 

Mostly, the Groundhog Day tradition is about the change in seasons and having enough harvest left to make it through winter.   There’s a rhyme that shows this:

As the light grows longer
The cold grows stronger
If Candlemas be fair and bright
Winter will have another flight
If Candlemas be cloud and rain
Winter will be gone and not come again
A farmer should on Candlemas day
Have half his corn and half his hay
On Candlemas day if thorns hang a drop
You can be sure of a good pea crop

The date itself is rooted in observations that Scottish, English and German farmers had hundreds of years ago that this was a waypoint (almost the midpoint) between winter (Winter Solstice was Dec 21) and the first day of Spring (Vernal Equinox is March 20) and that animals, like the Groundhog, wouldn’t come out of hibernation until the weather had started to turn for the better.

Coming out of hibernation too early or, in the case of humans, not having enough harvest left, could mean starvation.

In Europe, farmers watched the cues of hedgehogs but as people (e.g.,Germans)  immigrated to America (places like PA and other northeastern states), they incorporated the groundhog into their tradition and lore - and who wouldn’t! They’re awfully cute!

Happy Groundhog Day!
