Winter watch is on for monarchs in Georgia and other states (Linda May/DNR)
Each fall, monarch butterflies stream by the thousands across the southern U.S., bound for wintering grounds in Mexico. Come spring, this eastern population of the iconic butterflies will return to the U.S. and Canada to breed.
But not all monarchs migrate to Mexico. Some overwinter in the South. And some of those butterflies breed here.
Researchers want to know where, why and what this might mean for monarchs, an insect in decline and a candidate for Endangered Species Act listing.
This is where the public's help is needed.
Journey North, Monarchs Across Georgia, the University of Georgia and DNR are encouraging the public to report monarch sightings from now through March in Georgia and eight other coastal southern states, from Texas to North Carolina.
Studies show that monarch migration has changed in recent years. Understanding how and the species’ overwintering behavior is key to conserving monarchs.
Report sightings at journeynorth.org/monarchs.

LISTING WARRANTED, BUT LATER
The monarch warrants federal Endangered Species Act protection but that change is on hold because dealing with other evaluated species first is a higher priority.
The U.S. Fish and Wildlife Service said this week the warranted-but-precluded decision makes the monarch a candidate for listing (the same as the gopher tortoise east of Mobile Bay). The butterfly’s status will be reviewed each year until it changes.

Right whale "Chiminea" and her calf off Cumberland Island (Clearwater Marine Aquarium/NOAA permit 20556-01)
Recent sightings of three North Atlantic right whale calves off the Georgia/Florida coast stirred hope that right whales will post a strong calving season this winter.
Yet that hope is tinged with the sobering knowledge that these imperiled whales will require much more to avoid extinction. Here’s a brief overview.
Status: The population declined from an estimated 477 whales in 2011 to 366 in January 2019. There are fewer than 100 breeding females left. (Adult females drive population growth.) And in the past 10 years the number of calves per year has dropped to half the annual average – 24 – born the previous decade.
Deaths: Since 2017, 32 dead right whales have been found in the U.S. and Canada. The leading cause: “human interaction” from entanglements in commercial fishing rope or vessel strikes. Another 13 whales still alive have been documented with serious injuries from entanglements or strikes. Deaths are up, calving is down. “The math is pretty simple,” said Clay George, a DNR senior wildlife biologist.
Issues: Shipping traffic remains thick along the Atlantic seaboard. Millions of lobster and crab traps are set in New England and Canadian waters each year. Warming oceans have commercial fishers moving to deeper water, increasing the risk of whale entanglements. Stronger fishing rope is worsening whale injuries. Meanwhile, the life span of adult female right whales has shrunk and intervals between calving have increased. The male/female ratio has grown to almost 2-to-1.
Outlook: A proposed federal rule to reduce entanglements is in the works, spurred in part by a lawsuit. (Amidst the legal wrangling, the Gulf of Maine lobster fishery saw its sustainable certification suspended in August.) Massachusetts is holding hearings on reducing entanglement risks. Work is being done to develop “ropeless” fishing systems that either eliminate buoy ropes or keep them out of the water column.
What DNR is doing: The agency is again teaming with NOAA, Clearwater Marine Aquarium and the Florida Fish and Wildlife Conservation Commission to monitor right whales this winter by plane and boat. (The only known calving area for right whales is off the coast of Georgia and north Florida.) Calves will be biopsied for genetics research. George and staff will also help in any disentanglement efforts.
What you can do: Inform yourself, including about sustainable seafood. Support right whale conservation in Georgia. When boating November-March, be on the lookout and slow down for right whales. Stay at least 500 yards away and report sightings at 877-WHALE-HELP (877-942-5343).
The last word: “I’m still optimistic,” George said. “In the 2000s, we saw how quickly the population can grow if mortality is managed and females have lots of calves. If we can slow ships down in the right places, and remove heavy fishing rope from their habitat, the whales would have a fighting chance.”

An Oriental weather loach caught in McNutt Creek near Athens (Andrew Davis Tucker/UGA)
By ANI ESCOBAR and JIM PAGE
At first glance, the fish looks unassuming. Its chin barbels remind you of a catfish. Its spots suggest something tropical. Usually less than a foot long, this mild aquarium pet has a face of innocence.
However, the Oriental weather loach – documented for the first time in the wild in Georgia last month – could spell trouble for aquatic ecosystems across the state.
Also called the dojo or pond loach, this Asian species and popular aquarium fish has been introduced to Europe, Australia and at least 13 states in the U.S., including Alabama and Tennessee.
While sampling for Altamaha shiners in early November, UGA researchers were surprised to find several loaches in McNutt Creek, a tributary to the Middle Oconee River near Athens. After identifying the mystery catch, they worked with DNR to explore the fish’s status in the creek.
As part of that cooperative plan, the team did more sampling and collected at least 15 more loaches. That catch ramped up concerns about impacts the species might have if it is established and reproducing. ...

Carolina wren in a cavity (Todd Schneider/DNR)
By TERRY W. JOHNSON
I have long been intrigued by relationships that link different wildlife species. One such association is between woodpeckers and a suite of unrelated birds found in backyards across Georgia.
The connection is cavities. Those chiseled out by woodpeckers are frequently used by birds that cannot create their own. But while that usually involves nesting, in winter these cavities excavated in dead limbs and dead and dying trees can provide critical winter-roosting habitats for some birds.
On an extremely cold night, a roost can be the difference between living and dying. Unfortunately, suitable winter-roosting cavities are in short supply ...

Hammerhead worms are making headlines. Although these land planarians native to Asia and also called shovel-headed garden worms have been in Georgia for years, the media interest has been fueled by their potential size – they can grow up to a foot long – and significant ick factor. Report sightings.
Teachers and K-5 students can celebrate Georgia wildlife through art by taking part in the Give Wildlife a Chance Poster Contest. The “Nature Is Everywhere” theme of the 31st annual competition sponsored by DNR, the State Botanical Garden of Georgia and The Environmental Resources Network emphasizes that native wildlife and plants can be enjoyed close to home or far away.
Sprewell Bluff is being spruced up. DNR’s west-central Georgia fire crew burned about 750 acres on the two-part wildlife management area near Thomaston, prepping the site for planting longleaf and shortleaf pines, while also treating another 350 acres for invasive Vasey grass.
A new female bald eagle is settling into the Berry College nest streamed online, raising questions about whether she will be the popular nest’s new momma. The former resident female, who had noticeable injuries to her left foot suffered in 2013, has not been seen this fall. Stay tuned.

Frecklebelly madtom (Brett Albanese/DNR)
Frecklebelly madtom is a small catfish attracting significant attention. An upper Coosa River population of the 3-inch-long fish purportedly named for jabbing careless handlers with its spines is proposed for listing as federally threatened in Georgia and Tennessee.
Names in the news: DNR Law Enforcement Game Warden First Class Colte Shaske and Cpls. Jay Bright and Jordan Crawford were recognized for heroism at the recent Governor's Public Safety Awards. Shaske and Bright rescued two crew members of the Golden Ray as the cargo ship rolled over in St. Simons Sound last year. Before sunup Jan. 26 on the Ogeechee River, Crawford rescued three people, one suffering from severe hypothermia, whose boat had capsized and were clinging to trees in swift current. The South Carolina Department of Natural Resources' Felicia Sanders received the Biologist of the Year Award from the Southeastern Association of Fish and Wildlife Agencies. Sanders, Coastal Bird Conservation Project supervisor for the agency, is considered a coastal birds champion whose work has improved the understanding and conservation of these species.

Whimbrel migration reveals ties between Georgia and research into the warming Arctic (Tim Keyes/DNR)
If birds earned frequent-flyer miles, whimbrels would rack them up. Thousands of these big-bodied shorebirds migrate through Georgia each spring and summer, flying between nesting sites in the Arctic and wintering grounds at the mouth of the Amazon River. (Feeding up just before migration, whimbrels look like footballs with wings, says DNR wildlife biologist Fletcher Smith.) A new study of some 200 animal tracking studies explores how climate change in the Arctic and subarctic is affecting such migrants. The paper on the Arctic Animal Movement Archive, which includes whimbrel data from Smith, focuses on golden eagles, caribou and terrestrial mammal movements. Yet whimbrels reveal the ties between the Arctic and Georgia – whose barrier islands rate as a “landscape of hemispheric importance” for shorebirds – and the extensive network of partnerships committed to conserving such far-ranging species. This spring, DNR will add to its whimbrel work, using radio tags to better document how the birds use Georgia as a vital stopover to feed and rest. More on whimbrels in this story map by Manomet.
