Eastern kingbirds deserve their billing as tyrant flycatchers

On Saturday, June 27, I spotted two Eastern kingbirds perched on utility lines that extend over the fish pond at my home.

Eastern kingbirds are fairly common summer residents in the region, but they’ve not been at all common birds at my home. In fact, this recent sighting is only the second I’ve ever made of the species at my home in 30 years of birding. As best I can recall, the first time I saw this species at home was in the late 1990s. I’ve seen Eastern kingbirds in many other areas in the region, as well as on trips to Florida, Georgia, South Carolina and Virginia.

It didn’t take long to discover what had attracted the kingbirds to the fish pond. Using the utility lines as convenient perches, the birds continually swooped down over the waterlily-choked pond and returned to the lines with their catches. They were hunting dragonflies, an abundant insect at my fish pond. Based on my observations, they were quite skilled at capturing the dragonflies.

Kingbirds belong to an extensive family of birds known as tyrant flycatchers, or Tyrannidae. The family’s members are exclusively found in the New World. It is the world’s largest family of birds, with more than 400 species.

Tanagers, with 384 species, and hummingbirds, with 363 species, are close rival families when it comes to number of species. So are the pigeons and doves with 353 species, and Old World flycatchers with 345 species.

The Eastern kingbird is easy to recognize and identify. The bird’s plumage is a study in contrast, being black above and white below. In addition, there’s a noticeable white edge to the tip of the bird’s otherwise all-black tail. There is a red patch of feathers on top of the bird’s head, which gives this pint-sized tyrant a “crown,” but most birders, myself included, will tell you that this colorful patch is rarely seen and is instead kept concealed at most times.

The scientific name of the Eastern kingbird is Tyrannus tyrannus, a good clue to the bird’s militant nature. Kingbirds, which are about the size of an American robin, are famous for displaying aggressive behavior against much larger birds such as crows and hawks, as well as vultures and herons.

While some birds are all bluff, the Eastern kingbird often follows through with its attacks. According to the website All About Birds, kingbirds have been known to knock blue jays right out of a tree.

I’ve observed kingbirds tormenting such large birds as red-tailed hawks and turkey vultures. I once watched a kingbird get so close to a red-tailed hawk that it almost looked like the smaller bird was hitching a ride on the hawk’s back. I suspect the hawk lost a feather or two in the encounter, not to mention suffering a blow to its dignity.

Other North American kingbirds include Western kingbird, tropical kingbird, Couch’s kingbird, Cassin’s kingbird and the thick-billed kingbird. On a trip to Salt Lake City in Utah many years back, I got the chance to see a Western kingbird, the counterpart to the Eastern kingbird in that part of the country.

Look for the Eastern kingbird in open terrain that offers plenty of perches. These birds spend most of their time chasing and catching flying insects, which provide the bulk of the bird’s food during the summer months.

While the kingbird is probably to be lauded for helping control populations of insect pests, they are not discriminating in their choice of prey. As a result, kingbirds feed on beneficial insects, such as dragonflies and bees, as well as pests like flies.

A glimpse through the vegetation reveals one of the pond’s most voracious predators. Dragonflies consume many other species of insects, including some that are considered pests. Pictured is a female Blue Dasher. In turn, many birds, including Eastern kingbirds, feed on dragonflies. Kingbirds are skilled at snatching winged insects right out of the air.

Other flycatchers that are relatively common in the region include Eastern phoebe and Eastern wood-pewee. The region is also home to some pint-sized flycatchers during the warmer months, including least flycatcher, Acadian flycatcher, willow flycatcher and alder flycatcher.

Don’t judge the tyrannical kingbird too harshly. These birds are motivated to show aggression to other species due to an inordinate need to protect mates, young and territory. It’s not their fault that they are quite masterful at fulfilling this task.

Kingbirds are not the only birds to exhibit bold, brash behavior. Mockingbirds, brown thrashers and red-winged blackbirds are also quite pugnacious. At home, the male red-winged blackbirds have made numerous attacks on the resident red-shouldered hawks whenever these larger raptors venture too close to the cattail domain of the blackbirds.

Although the species faces potential habitat loss in both its summer range and tropical wintering grounds, the Eastern kingbird remains a prevalent bird across much of North America. It’s just not a common bird at my house, but perhaps my recent sighing of two kingbirds is a signal that’s about to change. Or it could mean that it will be another couple of decades before I see this species again at my home.
