The ruby-crowned kinglets, which passed through last fall in October and November, have returned, retracing their migratory path for the spring season and making their presence felt at my home with their jittery call notes and songs.
Most of the more recent returning birds have been on the smaller side. In addition to ruby-crowned kinglets, which arrived on April 1, I saw and heard a tiny blue-grey gnatcatcher on March 31.
As their name suggests, kinglets are tiny birds. In fact, about the only North American birds smaller than kinglets are some of the hummingbirds. The kinglets, known outside North America as “flamecrests” or “firecrests,” belong to the family, Regulidae, and the genus, Regulus. The family and genus names are derived from a Latin word, regulus, which means “rex,” or “king.” The name was apparently inspired by the colorful crown patches, often red, orange or gold, that resemble the royal “crowns” of kings. In addition to the two North American species, four other species of kinglets can be found in North Africa, Europe and Asia.
The gnatcatcher is also one of our smaller birds. I’ve always though that blue-gray gnatcatchers resemble a shrunken mockingbird. Like quarrelsome mockingbirds, gnatcatchers are noisy, scolding songbirds.
They are also determined to protect their nesting territories at all costs and will attack much larger birds. In North America, the gnatcatcher ranks in size with birds like kinglets and hummingbirds. Despite its diminutive status, the gnatcatcher acknowledges no superiors. According to the All About Birds website, blue-gray gnatcatchers are “fiercely territorial” and use vocal displays and postures to in intimidate other birds. They may chase a rival as far as 70 feet. If all this fails to deter an intruder, a gnatcatcher will escalate to midair confrontations.
Gnatcatchers don’t hesitate to call for reinforcements when warranted. With persistent squeaking they will drum up a brigade of feisty, feathered fighters to repel intrusions by potential predators too large for a gnatcatcher and its mate to handle on their own.
Ruby-crowned Kinglet
There are two species of kinglets in North America.
Although similar in size and overall coloration, the ruby-crowned and golden-crowned kinglets are easily distinguished from each other. Side by side, the two North American kinglets are easy to identify. The golden-crowned kinglet has a striped facial pattern formed by bold black and white stripes. The ruby-crowned kinglet, on the other hand, has a bold white eye ring but no striping. The golden-crowned kinglet has an orange crown patch, while the ruby-crowned kinglet has a red crown patch that is, more often than not, kept concealed. Both sexes of the golden-crowned kinglet possess a yellow crown patch, but only the male ruby-crowned kinglet boasts a scarlet patch of feathers atop the head. Observers can expend a lot of energy trying to get a look at the crown patches, which are typically only displayed when the bird is agitated.
There are 17 species of gnatcatchers. Most of these species reside in Central and South America. Some of the other species found in North America include California gnatcatcher and black-capped gnatcatcher.
Kinglets are very active birds. If warblers can be described as energetic, the kinglets are downright frenetic in their activities. The kinglets almost never pause for long, flitting from branch to branch in trees and shrubs as they constantly flick their wings over their backs. These bursts of hyperactivity can make them difficult to observe. Although small in size, these birds more than compensate for it with a feisty spirit that does them well through the harsh winter months.
Gnatcatchers are also constantly on the move, flicking their tails and darting through the branches of trees just starting to put out new green leaves. They glean caterpillars and small insects from the undersides of leaves to help fuel their demanding metabolism.
Kinglets and gnatcatchers often join mixed flocks comprised of other species of birds, some of which are regular feeder visitors. Perhaps by observing their flock counterparts, some kinglets have learned to accept feeder fare such as suet, meal worms and chopped nuts. Away from feeders, kinglets mostly feed on a range of small insects and arachnids. Gnatcatchers are strictly eaters of insects, but while a feeder holds no attraction for them, their curious nature often makes these tiny bird quite approachable.
Normally, kinglets have a rather fleeting lifespan. These tiny birds can be considered old if they live three or four years. There are always exceptions. The oldest golden-crowned kinglet on record was six years and four months old. That individual, a male, was documented by a bird bander in 1976, according to the website All About Birds.
Likewise, gnatcatchers live brief lives. The oldest known blue-gray gnatcatcher was a male, and at least four years, two months old, when it was recaught at a banding station in Pennsylvania and rereleased, according to the All About Birds website.

I’m still waiting for the smallest of the small to make its spring appearance. Ruby-throated hummingbirds are back, although I haven’t seen one yet. To share your first hummingbird sighting of spring, email me at ahoodedwarbler@aol.com.
