On the menu: everything from ‘murder hornets’ to snails among some of the things birds eat

Photo by Noutch/Pixabay.com • Although its name might suggest otherwise, the honey buzzard isn’t looking to dip its beak in something sweet. These unusual raptors raid the hives of bees and wasps to feed on the larval form of these stinging insects.

It’s not all bird seed and suet cakes for many of our feathered friends. Some of the world’s nearly 10,000 species of birds show some unusual tastes when it comes to their food. Facebook friend Philip Laws, who resides in Limestone Cove in Unicoi, shared a photo recently of a European honey buzzard, a type of raptor that’s developed a knack for raiding the hives of bees and wasps. A comment on the post suggested that the buzzard had developed a taste for sweets.

Actually, the truth’s a bit stranger. While many of the hives attacked by the buzzard are loaded with sweet honey, this aberrant raptor’s more interested in the larval bees and wasps housed in the hive’s honeycomb nursery chambers. The honey buzzard, also known as a pern or common pern, is related to such carnivorous raptors as sharp-shinned hawks and rough-legged hawks. 

If you’re worried about the so-called “murder hornets” in recent news articles, just know that the honey buzzard is the only predator known to feed on these insects. In fact, the honey buzzard takes great relish in dining on the larval forms of these wasps, which are more accurately known as Asian giant hornets. The honey buzzard’s head feathers are like scales, helping protect this vulnerable area from stings. In addition, some experts believe the buzzard’s feathers contain a chemical insect deterrent. This raptor also has long toes and claws it can use to dig into a hive.

While many birds are seed-eaters, few of them have evolved as grazers and vegetarians. In South America, however, there’s a most unusual bird known as the hoatzin. Also known by such names as “reptile bird,” “stink bird,” “skunk bird” and “Canje pheasant,” the hoatzin lives in swamps and mangrove forests in the Amazon and Orinoco basins of South America. 

One of the hoatzin’s claim to fame is that it’s a folivore, which simply means it eats foliage, or leaves, as well as fruit and flowers. The bird has even developed a special stomach called a “rumen,” that permits bacterial fermentation of the leaves it devours. Some studies indicate that as much as 80 percent of a hoatzin’s diet consists of leaves. 

The great blue turaco is an African bird that, like most other members of the turaco family, eats mostly fruit, but this bird will eat leaves and even algae when fruit is scarce. Closer to home, the cedar waxwing’s a well-known fruit lover. Birds that eat mostly fruit are known as “frugivores.” A large flock of waxwings can make short work of the fruit of holly or mulberry trees. The berries they eat can even affect their appearance. Some waxwings show an orange, not yellow, tail tip. The orange coloration is the result of the birds eating honeysuckle berries with a red pigment.

Fans of French cuisine have probably sampled “escargot,” which is basically culinary snails. Of course, humans have a wide range of unusual tastes. There is a species of bird that specializes on feeding on snails, albeit without the garlic and butter of the traditional French dish. The snail kite is found in southern Florida, especially in the Everglades. This raptor feeds almost exclusively on apple snails and has even evolved a specialized hooked beak to help rip the snail from its protective shell. 

Around the globe, various birds have evolved as “sanitation crews” for the ecosystems that they inhabit. Vultures in both the Old World and New World feed on carrion, although a few species will tackle living animals. On the African plains, different vultures have evolved to clean up the carcasses of large herbivores. Different ones have become quite familiar to fans of nature documentaries. These are the large vultures that quickly claim a carcass once lions and other predators have eaten their fill.

Some of the species include Egyptian vulture, Indian vulture, lappet-faced vulture and griffon vulture. Many of the Old World vultures are declining at alarming rates largely due to poisoning by insecticides and other chemicals. Their populations are crashing in a similar way to that of bald eagles, which were brought to the brink of extinction because of the use of the pesticide DDT in the 1950s an 1960s. 

While I wouldn’t suggest we offer snails, salads or carrion at our feeders, the dietary habits of some of our birds just go to show what fascinating creatures birds truly are.

Ongoing pandemic doesn’t stop club’s annual Spring Bird Count

Photo by Bryan Stevens • Several species of herons were located on the Spring Bird Count for Northeast Tennessee,, including Black-crowned Night Heron.

Not even a pandemic could prevent the Elizabethton Bird Club from conducting the 77th consecutive Elizabethton Spring Bird Count. The annual survey was held Saturday, May 2. The area covered included Carter County and parts of the adjacent counties of Johnson, Sullivan, Unicoi and Washington. Fifty-one observers participated in 22 parties using the suggested social distancing protocols.

Although I counted alone due to social distancing, I had a wonderful day. I even added a new life bird to my list when I saw a Mississippi Kite at Sycamore Shoals State Historic Park in Elizabethton. My fellow participants also found some good birds.

A total of 159 species were tallied. The recent 30-year average is 149 species. However, broken down by decades, this particular count has seen a steady increase during that period, as follows: 1990s had an average of 145 species, the 2000s saw that increase to 150 species, and the 2010s saw another rise to 153 species. The all-time high on this count was 166 species back in 2016.

The count found 27 species of warblers, including such notable finds as Blackpoll Warbler and Nashville Warbler. The most abundant warblers were Hooded Warbler — which is my personal favorite — and Ovenbird. Each of these had 171 individuals counted.

The most abundant bird was Cliff Swallow with a total of 782 individuals counted. These swallows form nesting colonies under bridges and other structures. They have greatly increased in numbers over the past couple of decades. The other common birds, in descending order, were American Robin, 780; European Starling, 740; Canada Goose, 440; and Cedar Waxwing, 381.

Some of the notable misses on this spring’s count included Northern Bobwhite, Sharp-shinned Hawk, Common Nighthawk, Horned Lark, and Cape May Warbler.

I hope everyone’s seeing wonderful birds this spring.

Mississippi kite glimpsed on spring count becomes latest listed ‘life bird’

Photo by Richard/Adobe Stock • A solitary Mississippi Kite sits perched in a lakeside tree. These graceful raptors take their prey mostly while on the wing.

If you know many birders, you have likely heard them talk about “life birds.” These are any species that a birder has seen and identified in the wild for the very first time. It can be any bird species at all that the birder observes for the first time, whether it is a commonplace bird like a song sparrow or something slightly more exotic.

While taking part in the 77th consecutive Elizabethton Spring Count on Saturday, May 2, I saw something that, for our region, could be considered a little more exotic. The sighting certainly ranked as unexpected.

Unless one travels extensively, life birds can be hard to get once people have added to their lists most of the common birds around their homes. Finding a life bird during the ongoing pandemic brings its own challenges. I haven’t added a new life bird to my own list since a visit to South Carolina in June 0f 2016. During that visit to Huntington Beach State Park, I added a least bittern to my list of “life birds.”

My most recent “life bird” appeared closer to home and might qualify as my most unexpected life bird ever. The bird flew into view and onto my life list during the annual Spring Bird Count, which was conducted by members and friends of the Elizabethton Bird Club. Due to social distancing, many participants counted solo this year, myself included, although a few married couples birded together. I’ll always remember my pandemic spring count, especially for the 46th bird on my tally list for the day.

I found myself in the parking lot at Sycamore Shoals State Historic Park in Elizabethton around 11 in the morning. I wanted to scan the evergreens in that vicinity for Cape May warblers, a migrant that finds the tall conifers to its liking. I didn’t find any warblers, but I did surprise a perched raptor into making a short flight.

The instant I saw the bird launch itself into flight, I knew I was watching something out of the ordinary. The bird flew with a combination of grace and power that reminded me of a falcon, but I also glimpsed a barred tail that reminded me of one of the accipiter hawks. Then it landed on a dead branch in a tall sycamore that must have permitted the raptor an unobstructed view of the entire park. Although I’d never until that moment seen a Mississippi kite, I have studied illustrations and photographs. I felt fairly certain of the bird’s identity even before I used my phone to call up some birding sites to confirm my identification.

Photo by Bryan Stevens • This Mississippi Kite became the first of its kind ever observed on one of the Elizabethton Bird Club’s Spring Bird Counts for Northeast Tennessee.

That’s when the fact I was birding solo hit home. I wanted some additional witnesses to this very unexpected find. In lieu of other observers, I turned to my camera. The bird had turned its back to me, but I snapped some photos and then made my way to a position that I hoped would allow for better photographs.

Alas, the resident American crows at the park had different ideas. Detecting a raptor in their midst, about a half dozen crows gathered to harass the perched kite. Before I could snap a new round of photos, the kite took flight and flew into a stand of tall trees located between the park and Sycamore Shoals Hospital.

Only a few years ago, a Mississippi kite in Northeast Tennessee would have been unheard of. The hills and mountains of the region are simply not the expected habitat for these graceful raptors. Faith Reeves, a resident of Elizabethton, Tennessee, a Facebook friend and fellow birder, saw the first two Mississippi Kites ever found in Northeast Tennessee. She saw and photographed the birds in her own yard on May 20, 2014, and May 13, 2016.

In addition, Don Holt observed a Mississippi kite in Washington County, Tennessee, on April 16, 2017.

Rick Knight and several other birders also saw several Mississippi Kites for about a week in late August of 2016. Observers estimated that these sightings involved from two to five different kites.

“The August observations are our only fall records,” said Rick Knight, a long-time compiler of birds sightings in the region. He added that fall is the season when kites are likely to linger.

“All spring records are overshooting migrants and are one-day-wonders,” Knight explained.

Hearing his explanation, I felt even more privileged to have witnessed this “one-day wonder” in my home county.

The Mississippi kite is a beautiful raptor. Adults are grayish-white with the head often appearing pale gray or almost white. Although the Mississippi kite can attain a wingspan of three feet, these birds weigh only seven to thirteen ounces. They feed almost exclusively on insects, which they capture in flight. Some of the insects, such as cicadas and grasshoppers, are ones that damage crops, making the Mississippi kite a friend to farmers.

These kites breed and nest in the central and southern United States, but they have expanded their range north in recent years. They leave the United States in fall to spend the winter in southern South America.

Several years ago I got the thrill of adding a swallow-tailed kite to my life list in some agricultural fields in southwestern Washington County. I’ve also seen swallow-tailed kites in Florida. There is one other member of the kite family that I’d like to add to my list. The snail kite is a dark bird with a hooked beak designed for feeding on snails found in wetlands. This specialist resides in Florida, as well as the Caribbean and Central and South America.

Other kites found around the world include the double-toothed kite, plumbeous kite, whistling kite, square-tailed kite, red kite and black kite.

It’s been a spring filled with many amazing bird observations. I can’t speak for others, but thanks to that remarkable kite sighting and glimpses of some other fascinating birds, not even having to bird solo in a pandemic can bring me down. I’ll provide more details on this year’s Spring Bird Count for Northeast Tennessee in next week’s column.

Region’s two oriole species make their spring return

Photo by MillionPM/Pixabay.com • Oranges, as well as offerings of grape jelly, are often successful at luring Baltimore orioles to feeders.

Earlier this spring, Kaylynn Wilster, who resides in Jonesborough, Tennessee, emailed me for information about orioles.

“Do you know when the orioles return to our area?” Kaylynn asked. In her email, she also shared that she had a female Baltimore oriole gathering nesting materials in her yard last summer.

“I put out an oriole feeder this year,” she added. So far, she noted, only chickadees have discovered the grape jelly.

In addition, Brenda Hickman Dishner, who lives near Holston Dam in Bristol, Tennessee, contacted me through Facebook to ask if I have seen orioles in the area.

Brenda added that she has put out oriole feeders for the past three years with no luck.

It seems many people are hoping to welcome these bright orange and black birds to their feeders. In my reply to Kaylynn and Brenda, I told them to expect orioles to arrive in late April and early May. I’ve found orioles uncommon visitors to my home, but my prediction on timing proved more or less correct.

Gloria Blevins shared a photo of the Baltimore orioles that have been visiting her home in Damascus, Virginia. In a Facebook message, she shared that the orioles have been feeding on grape jelly that she had provided them since May 2.

Although she no longer lives locally, Kathy Noblet has been seeing lots of Baltimore orioles at her home in Mount Vernon, Ohio, since late April. Her photographs of these colorful birds have been nothing short of amazing. She has shared new photographs on Facebook on an almost daily basis for the past couple of weeks.

“The orioles continue to come to my deck and pig out on grape jelly,” Kathy posted on May 6. “They are fun to watch!”

I also heard back from Kaylynn on May 15. “There was a male oriole getting a drink at my pond about four days ago,” she informed me in an email.

Photo by USFWS • Baltimore orioles, like this male, are members of the blackbird family, making them relatives of species such as Eastern meadowlarks, brown-headed cowbirds, common grackles and red-winged blackbirds.

The Baltimore oriole, despite its bright plumage, is a member of one of the blackbird clans, known in scientific circles as the Icterus genus. In his book, “Birds of Forest, Yard, and Thicket,” John Eastman notes that there are 26 species in the genus, eight of which nest in the United States.

In the eastern United States, there are only two orioles — the Baltimore oriole and its smaller relative, the orchard oriole. The western half of the nation is home to a half dozen orioles, including Bullock’s oriole, Scott’s oriole, Audubon’s oriole, hooded oriole and Altamira oriole. I saw several gaudy, noisy Bullock’s orioles during a trip to Utah in May of 2006.

Tall trees are an essential part of the Baltimore oriole’s favored habitat. Baltimore orioles are well-known for their colorful appearance, but their fame also rests with a sack-like nest that Eastman describes as a “durable marvel of tight-woven plant fibers” in his informational book. Eastman also notes that during another era in America, the Baltimore oriole often built its marvelous nests in American elms before Dutch elm disease almost eradicated these trees from the landscape. He reports that maples, willows and apples have served as nesting trees in the absence of elms. Once the hard-working female oriole sets to work, she may spend eight days or longer weaving plant fibers into a strong pouch suspended from the outer ends of drooping branches. The durability of the nest means that other birds, including house finches, may occupy the old nest once abandoned by the original inhabitant.

Orioles are present in the region from April to October, retreating to the American tropics for the winter. There they may live on plantations that produce such much-coveted crops as bananas, coffee and cacao, which is the essential ingredient for chocolate.

George Calvert, Lord Baltimore

The Baltimore oriole is named in honor of one of the founding fathers of the state of Maryland. George Calvert, or Baron Baltimore, was an influential English colonist instrumental in establishing the colony of Maryland. His servants wore orange and black uniforms, which inspired early American naturalist Mark Catesby to name the bird the Baltimore oriole. The bird’s association with the the city of Baltimore and the state of Maryland have continued to this day. The bird is also famous as the namesake of one of America’s professional baseball teams.

Baltimore orioles eat insects and fruit, but these adaptive birds have also developed a fondness for sweet nectar. Orioles no longer have to raid sugar water feeders meant for hummingbirds. Many manufacturers of bird-feeding equipment now produce affordable sugar water feeders specifically designed for use by orioles. Many bird enthusiasts also use orange slices and grape jelly to lure orioles into their yards. I’ve tried these tricks, but I’ve attracted more gray catbirds and scarlet tanagers than I have orioles. In my book, that’s not a disappointment. I happen to like catbirds and tanagers.

With orioles, I’ve had better luck by refraining from a bit of pest control. Back in the late 1990s, I observed a male Baltimore oriole visiting a large caterpillar tent in the branches of a cherry tree. The bird methodically plucked the caterpillars from the silken tent, eating them one after the other. I’ve since learned that this is not an odd occurrence for Baltimore orioles. While many birds avoid spiny and hairy caterpillars, orioles actively seek them out and do a great service by reducing the damage these hungry caterpillars can inflict on the environment.

If you’re wanting to see orioles, I can share some area “hot spots” for these colorful birds. The waterfront at Winged Deer Park in Johnson City, Tennessee, has fewer tall trees than it did a few years ago, but the remaining trees still attract orioles. Warriors Path State Park in Kingsport, Tennessee, has long been a place that local birders depend on for sightings of Baltimore orioles. I also had some impressive sightings of both orioles at Hungry Mother State Park a few years ago. Although those birds could have been spring migrants, this park in Marion, Virginia, certainly offers habitat that orioles would find attractive.
