A reminder for those into bobcats (and who wouldn't be into bobcats?). Conservation biologist and educator Shauna Weyrauch will give a program on Ohio's recovering bobcat population this Saturday, February 7 at 1pm at the fabulous nature center at Highbanks Metro Park in Delaware County (Ohio). In addition to all of Shauna's interesting information and photos, there are Purple Finches visiting the center's feeders! Hope to see you there!
Ohio Birds and Biodiversity
A romp through the diverse flora and fauna of Ohio. From Timber Rattlesnakes to Prairie Warblers to Lakeside Daisies to Woodchucks, you'll eventually see it here, if it isn't already.

Loggerhead shrikes are predatory birds. Why are they endangered in Ohio?
It wasn’t long before we saw our first loggerhead shrike, perched on a roadside wire. By the time our travels were over, Shauna and I had seen 80 or more of these fascinating songbirds.
The loggerhead shrike is so named because of its disproportionately large noggin – a “loggerhead.” Perhaps more interesting is its scientific genus name, Lanius. That Latin word translates to “butcher.” That relates to an oft-used colloquialism for the shrike: butcherbird.
Put it this way: If shrikes were the size of whooping cranes, we humans could be in a world of hurt. While a loggerhead shrike is only about the size of a catbird, their brutality is on the level of a great white shark.
Their prey can range up to the size of a vole – which weighs at least as much as the shrike. Remarkably, in areas where they occur with 13-lined ground squirrels, shrikes can capture and kill those.
One of these mammals weighs up to 250 grams – five times the heft of a shrike. That’s akin to a psychotically homicidal Pee-wee Herman taking down a passive André the Giant. More common fare includes large insects such as grasshoppers, big spiders and even amphibians and reptiles.
While shrikes have large powerful raptorial bills, they lack the strong feet and talons of raptors. Hence comes the world of hurt part for victims. If you are lucky, the attacking shrike quickly snaps your vertebrae and the end comes fast.
Unlucky victims do not die rapidly and are relocated to a sharp object such as a projecting nail – as in my photo – sharp thorn or some similar skewering implement.
The prey is unceremoniously impaled, with the barbed wire or whatever serving as its substitute talons. Once stuck, pieces can be ripped off the body and eaten at the shrike’s leisure. The stuff of nightmares, so it would seem, but it’s business as usual for the butcherbird.
Loggerhead shrikes once were common, at least locally, in Ohio. While originally more of a southern bird, the clearing of the vast eastern deciduous forest – which blanketed 95% of Ohio – allowed this species of open country to expand northward. They reached their peak here in the first few decades of the 20th century.
At the time, agriculture was far more wildlife-friendly than it is today. Farming landscapes tended to be mosaics of cropland, fallow fields and meadows, and brushy fencerows that supported an abundance of insects, rodents and small songbirds – the shrike’s stock in trade.
In his 1935 publication "Distribution of the Breeding Birds of Ohio," ornithologist Lawrence Hicks noted that loggerhead shrikes were “very common” in some regions of the state and were likely present in every county.
As agribusiness increasingly eliminated non-cropland, increased the use of pesticides and segued to massive planting of monocultures, it greatly reduced biodiversity. Shrikes began to decline by the 1940s and that trend continued to the present.
When I penned my book, "Birds of Ohio," in 2004, I noted that there were perhaps only two nesting pairs of shrikes annually. Twelve years later, I was a co-author of "The Second Atlas of Breeding Birds in Ohio" and authored the loggerhead shrike account.
By this time, the shrike had been listed as endangered by the Ohio Division of Wildlife, a status it still carries. In my account, I noted that it was now one of Ohio’s rarest breeding species.
I suppose one might be forgiven for thinking that perhaps it’s a good thing that such a barbaric predator has been vanquished. But that would be to think in anthropomorphic terms. Shrikes just do what they evolved to do, same as sharks, mosquitoes, snakes, scorpions, and human beings.
While it might appear that all is lost for loggerhead shrikes in Ohio, as agriculture now covers 55% of the state, and the days of shrikes (and lots of other wildlife) in those regions are over, new possibilities have arisen from an unlikely source.
Strip mining – using large machinery to uncover and extract coal seams – began in Ohio about 100 years ago. In total, nearly 450,000 acres were mined – an area larger than Franklin County.
These sites were left as lunar wastelands largely devoid of flora and fauna. In 1972, laws were enacted that required the reclamation of former mine lands. Tens of thousands of acres in southeastern Ohio have been reclaimed, and these sites resemble savannas and prairies – excellent shrike habitat, or so it would appear.
By the time reclamation began to bear fruit, shrikes had already collapsed and thus could probably not populate these sites.
Enter our neighbor to the north, Canada. Loggerhead shrikes formerly occurred in the provinces of Ontario and Quebec but had disappeared there as well. In the late 1990s, Canadian biologists embarked on a captive breeding and release program, introducing shrikes into suitable habitat. This effort worked and has maintained a core shrike population. In 2012, shrikes fledged an impressive 82 chicks.
Perhaps it’s time to emulate the Canadians and consider a similar program to repatriate the charismatic butcherbird back to the Buckeye State.

Rock Pigeons occupy expensive Gulf retreats
I will note that Rock Pigeons are a personal favorite bird. I'm aware that they aren't native - pigeons were introduced to North America in the 1600's. But insofar as I know, they do little or no harm ecologically - even the smattering of pigeons that return to their wild roots and nest on cliffs in wild places. About all of the "problems" they cause are human-centric. Further, pigeons are gorgeous birds. The flock in the photo contains some of the classic "blue-bar" birds with grayish body and two thick black wing stripes - that's the wild phenotype. Some stunning coal-black individuals are also in the photo, and color variation in Rock Pigeons is wildly variable.

Clapper Rail
A Clapper Rail (Rallus crepitans) peeks from a dense saltmarsh along the Gulf of Mexico. This morning - January 12, 2026 - dawned clear and beautiful, and shortly after leaving the hotel, we passed by an opening in a large coastal saltmarsh that was full of birds. We pulled over, carefully approached the spot, and were able to get fairly close, and just as good, could get on the ground to better depict our subjects on their level.
After shooting more obvious subjects - various herons and egrets, Roseate Spoonbills, ibises, etc. - I noticed a Clapper Rail peeking from the marsh. Soon it became apparent that there were three rails, and two of them, apparently unaware of or indifferent to our presence, came into the open and put on a show.

Yellow-rumped Warbler is Ohio's only regular wintering warbler
Forty-one warbler species have occurred in the Buckeye State, and 36 of them occur annually. Many species occur in large numbers, especially during spring and fall migration.
But May – peak of vernal migration – is still months away. That’s a long time for those of thirsting for colorful Blackburnian, Cape May and Magnolia warblers and their dashing brethren. Collectively, our warblers display a palette of hues that would dazzle the most ambitious artist.
However, most of our warblers are currently residing in haunts that should make most of us northerners envious: southern Florida, Colombia, Costa Rica, the Dominican Republic, Mexico. Most species of warblers winter in tropical climes with some species as far south as Argentina and Bolivia.
Take hope, though – we still have the hardy yellow-rumped warbler! This feathered tough bucks the dominant paradigm of its southbound snowbird associates and routinely winters in northerly latitudes such as Ohio.
The yellow-rumped warbler is the most abundant North American warbler with a population estimated at 150 million birds. “Butterbutts,” as they are slangily known, are among our showiest warblers, but people get jaded to them due to their commonness. “Just another butterbutt” is an oft-heard refrain amongst birders poring through the waves of spring and fall migrants.
No yellow-rumped warblers occupy Ohio during the summer months. Their breeding season lies well to our north, where they nest across the length and breadth of the conifer-dominated boreal forest.
Breeding butterbutts can be found from Alaska to Newfoundland, and south to northernmost Michigan. Others breed further south at high elevations in the Appalachian Mountains and the western Rocky Mountains.
While both sexes sport the telltale yellow rump, the male is admittedly flashier. It is clad in showy black and grayish-blue plumage highlighted by a golden throat and flanks. At one time, scientists cleaved this widespread warbler into two species: the eastern “myrtle” warbler and the western “Audubon’s” warbler.
Males of the latter, named for the legendary frontiersman and ornithologist John James Audubon, wear a lemony-colored crown patch and flashy yellow throat. The myrtle warbler – which birds appearing in Ohio are – lack the golden crown and have white throats.
Due to a zone of hybridization, where myrtle and Audubon’s warbler ranges meet, scientists lumped them into one species – the yellow-rumped warbler – in 1973. To this day, many birders still refer to these subspecies as myrtle and Audubon’s warblers.
Breeding yellow-rumped warblers are tightly tied to coniferous trees, including fir, pine and spruce. Away from that habitat, however, they are perhaps the most versatile of all our warblers in habitat use.
I would not be surprised to see a butterbutt in nearly any habitat imaginable and probably have over the years. The warblers are also adept at finding and eating a wide range of food, which, in addition to their vast breeding range, probably plays a big role in their success.
This hardy, versatile warbler also winters further north than any other warbler. While some birds range as far south as the Caribbean and Central America, most winter in the U.S.
I’m in southeastern Texas as I write this column, and yellow-rumped warblers are everywhere. But just a week ago, Shauna and I participated in the Hocking Hills Christmas Bird Count in Ohio and found seven butterbutts in our turf. Yellow-rumped warblers winter commonly north to Ohio and other Midwestern states.
A prime reason that butterbutts can survive northern winters is their ability to include lots of fruit into their diet. And a major source of that fruit is one of the most despised native plants in North America: poison ivy (Toxicodendron radicans).
I suspect that poison ivy is THE primary reason that butterbutts can successfully overwinter in northern climes, while their mostly insect-eating warbler relatives must retreat to more southerly buggy latitudes.
The yellow-rumped warbler in the accompanying photo is scarfing down poison ivy berries, and I made that image on the aforementioned Hocking Hills bird count in subfreezing temperatures.
Poison ivy fruit fuels many species of wintering birds, not just butterbutts. In many ways, the rash-inducing vine is one of our most important wildlife plants. That’s a hard case to make to most people, but the yellow-rumped warblers sure appreciate poison ivy.

Armadillo, and Texas
A Nine-banded Armadillo (Dasypus novemcinctus) crosses a rural East Texas lane. These curious armored tank-like mammals are primarily nocturnal, but we found this one rooting about in a grassy verge during the day. It took about 20 minutes before the animal finally showed itself, allowing us some nice unobstructed images.
Shauna and I have been in the Houston area since last Friday and have had a great time photographing birds and other wildlife. Lots of action and I have scores of interesting images, and some of that should make its way onto this blog eventually.
I was invited to speak at the River Oaks Garden Club's annual Sadie Gwin Blackburn Environmental Seminar (this was the 35th one), held at the Houston Museum of Fine Arts. That took place this morning and we had a nice turnout. River Oaks Garden Club is a high productivity group, and this was one of the best organized events that I've been to. My topic was Growing Caterpillars: A Tangled Tale of Birds, Plants, and Conservation.
We return home tomorrow but came down last Friday to have about five days to explore and photograph. Most of our time was spent along the Gulf Coast, but we ranged as far west as Aransas National Wildlife Refuge, and as far east as Anahuac National Wildlife Refuge. Two photographic highlights were Long-billed Curlew and Snowy Plover, but there was so much more, including some very cool plants. More to follow!

Ribbit! magazine offers informative, engaging material about nature
January 4, 2026
Last June, prior to our deliberations, Bettina Cooper came to the Green Fund to make a pitch about a new publication she had started, Ribbit!, a magazine geared toward younger generations.
I was thoroughly impressed by Cooper's presentation and the magazine, and the reasons for producing it. The rest of our board agreed, and we helped with funding.
Cooper kindly sent along a hard copy of the most recent Ribbit! (Issue 6, Winter 2025/26), which features an eye-catching color image of a great horned owl on the cover. That ties to an article inside titled “Amazing Owl Adaptions.”
Being an owl aficionado, I eagerly pored through the article, which was penned by naturalist Kate Brierley, who works at Blacklick Woods Metro Park.
Like all the magazine’s other material, Brierley's owl piece is well-written, engaging and informative. As younger people are the target of Ribbit!, the owl article is easy to understand, explains the basics of owl physiology and behavior clearly and simply, and uses wonderful photography and graphics to punctuate important points.
Other articles in the issue include pieces on the ice age, cold-hardy animals, how to better find wildlife, speaking up for nature, and more. A staple in each issue is “Columbus Nature News,” which informs readers about upcoming events such as Christmas Bird Counts, World Wetlands Day and the Winter Hike Series with Columbus and Franklin County Metro Parks.
A personal favorite in the “Nature News” section was a short note recognizing Squirrel Appreciation Day, which falls on Jan. 21. Squirrels are incredibly important components of ecosystems, but do not get their fair share of love. Going to bat for the underdogs is an admirable trait, and the producers of Ribbit! certainly do that.
Magazine staff strive to get notable authors, and the current issue’s ice age article was written by Daniel Kelley of the Ohio State University and Jamey Stutz of ODNR’s Division of Geological Survey. The geologists do an admirable job of explaining the complexities of the ice age and its impact on Ohio, all in easily understood language.
The six issues to date contain an impressive array of subject matter, and all of them are excellent intellectual fodder for growing minds. And no ads!
Each issue is about 30 pages, features color throughout, and layout and design are superb. Ribbit! is free, with funding coming from a variety of sources. Donations are appreciated and provide a valuable part of the magazine’s funding.
After reading several issues, I feel Ribbit! hits its mark of educating younger people and should be of interest to kids from K-12, and adults, too.
Ribbit! is produced under the auspices of a group called Naturewise Columbus and its eight-member board of directors.
To learn more about the people who produce the magazine, visit their website at naturewisecolumbus.org.
The magazine is available, free of charge, at libraries, community centers, parks and various public events. Interested parties can also view magazines on the Ribbit! website, ribbitmagazine.com.
The next issue comes out March 1.
Environmental education should be part of the basic curriculum for students, and Ribbit! magazine provides a big dollop of that in a very interesting package. I highly recommend it, and please help spread the word.
