Brown thrashers make first spring appearance

In this time of social distancing when the daily routine can become flat and dull, I’m rejoicing that many of my favorite birds are returning after their long winter absence. One of the first to return has been brown thrashers, which made a first spring appearance on March 25. I suppose I should use the word “appearance” with reservations since I only heard a thrasher singing from deep in the concealment of a brushy thicket. A few days, later, however, a pair of brown thrashers began visiting my suet feeders.

I posted about the return of this large songbird on Facebook and immediately discovered that the brown thrashers must have returned to the region en masse.

Aubrie Abernethy, a resident of Johnson City, Tennessee, posted that her brown thrasher has arrived a day earlier than mine.

Dianne Draper, a resident of Jonesborough, Tennessee, posted, too. “Ours is back also,” Dianne wrote.

Michelle Sparks in Bristol, Tennessee, posted on my Facebook page that she had seen her first spring brown thrasher earlier that same week.

Diane Gonzalves from Abingdon, Virginia, responded on the post about brown thrashers by asking about another imminent arrival. “I assume the hummingbirds should be here soon?” Diane asked.

I responded that the first ruby-throated hummingbirds should be arriving at any time. Please watch out for these tiny birds and get your sugar water feeders outside to welcome them. I will do my annual round-up on first hummingbird sightings of the spring again this year. Share your sighting by emailing the time and date of the arrival to ahoodedwarbler@aol.com. Readers can also contact me via Facebook.

The brown thrasher (Toxostoma rufum) belongs to the family of “mimic thrushes,” which provides a label for a group of songbirds capable of imitating the songs of other birds. Mimidae, the Latin root for “mimic,” provides the scientific name for the family, which includes mockingbirds and the New World catbirds, as well as thrashers. The Northern mockingbird is best known for the ability to mimic, but relatives like the gray catbird and brown thrasher are also talented mimics.

The thrasher is a fairly large songbird about 11.5 inches long with a wingspan of 13 inches. Much of the body length comes from the bird’s long tail feathers. A thrasher weighs, however, only about 2.5 ounces.

The brown thrasher is not a picky eater. It’s known to eat everything from berries and nuts to insects and small lizards. It’s also aggressive in defending its nest and young. John James Audubon, a French-American ornithologist, naturalist and painter, painted quite the dramatic scene of a group of brown thrashers valiantly defending a nest from an attacking snake. The painting is so detailed that one has to imagine Audubon based his work on a real-life experience. His work, originally painted in the early decades of the 1800s, still holds up today.

Early American naturalist and artist John James Audubon painted a dramatic scene of brown thrashers defending their nest from an attacking snake.

Incidentally, Audubon knew the brown thrasher as the “ferruginous thrush.” Another former common name for this species was “brown thrush.” The brown thrasher breeds across the United States and Canada east of the Rocky Mountains. Thrashers withdraw from the northern part of their range in the winter months, spending the season in the southeastern United States.

They are familiar birds in southern gardens. In fact, the brown thrasher is the official state bird of Georgia and also provided the name for Atlanta’s National Hockey League team, the Atlanta Thrashers. The thrasher became Georgia’s state bird due to passage of a Joint Resolution of the Georgia General Assembly in 1970.

Other new arrivals in the closing days of March included blue-gray gnatcatcher, blue-headed vireo and broad-winged hawk. So, what are you seeing? Let me know when the hummingbirds arrive.

Gray catbirds require some gentle coaxing to give up shy habits

The gray catbird is a baffling bird with a personality that runs the gamut from introverted to extroverted, sometimes depending on the season and at other times seemingly just on a whim. With some gentle persuasion, however, people can gain a catbird’s trust and develop a fun friendship with these clever songbirds.

One summer, all I needed to do to win over the catbirds was to offer some less-than-perfect strawberries and blueberries. A few blemishes on the fruit didn’t bother the resident catbirds at all, and they soon became accustomed to receiving such treats.

Your first introduction to the catbird is likely going to occur when you hear what sounds like an irritable feline hiding in a hedge, thicket or dense shrub. Upon closer examination, you may get a glimpse of a charcoal gray bird roughly the shape of a Northern mockingbird but smaller. A black cap and a patch of rusty-red feathers under the tail are the only exceptions to this bird’s overall gray plumage.

Catbirds are experts at concealing themselves from prying eyes. The gray plumage blends into the shadowy sections of the tangles and thickets where the bird likes to hide itself. However, even when gray catbirds are reluctant to be seen, they’re almost eager to be heard. The catbird is extremely vocal, with several calls and songs in its repertoire, including the rather faithful rendering of a fussy cat’s meow that provides this bird its common name.

They’re part of a family related to thrushes that are known as “mimic thrushes.” Besides its surprisingly accurate rendition of a feline, the catbird has several other common vocalizations. Despite their shy nature, they’re extremely curious. Imitating their calls or simply producing a squeaky sound will usually persuade the bird to move out of cover and search for the source of the noise.

Catbirds are part of the parade of returning birds each spring that includes species like rose-breasted grosbeaks, scarlet tanagers, Baltimore orioles and indigo buntings, but because they lack the brilliant plumages of these other birds their arrival would probably go unnoticed if not for the fact they are extremely noisy for the first few weeks they are back. Then they go silent again and remain quieter as they take up the serious business of raising young.

However, in a mood that appears to swing with the seasons, gray catbirds emerge again in late summer and early fall when they feast on such fruit as elderberries and wild cherries while making their whiny cacophony of calls from any tangle or thicket where they happen to be.

The catbird belongs to the genus Dumetella. The name is based upon the Latin term dūmus, which roughly translated means “thorny thicket.” Dumetella, in turn, means “dweller in the thornbushes” or “small bird of the thornbushes.” It’s a rather apt description for a bird fond of habitats often dominated by thorny vegetation. Older common names for the gray catbird included cat thrush and slate-colored mockingbird.

They are related to thrashers and mockingbirds, but scientists find them just different enough to warrant placing the gray catbird in its own genus. A relative known as the black catbird, which ranges throughout the Yucatan Peninsula of Mexico, as well as northern Guatemala and northern Belize, also belongs to a genus of its own. Both catbirds are classified as “mimic thrushes,” or Mimidae, of which there are about 30 species in the New World. There is a totally unrelated family of catbirds that ranges through Australia, Asia and parts of Africa.

The gray catbird is not as an accomplished mimic as some of its relatives, such as the Northern mockingbird. Males have motivation to constantly expand their repertoire, however, as doing so increases the likelihood of attracting a mate. They imitate other birds, but some have been recorded imitating frogs and other non-avian singers.

While not generally considered a bird to visit feeders, people have succeeded in attracting catbirds to feeders designed to offer grape jelly or orange slices. Planting fruit-bearing shrubs and trees is the best means of attracting these fascinating birds to your yard and garden.
