Eastern Phoebe

The Eastern phoebe is a passerine, belonging to one of the largest bird families in the world — the flycatcher family — which contains over 400 species. They sing out their name in short and unmelodic songs, though this call is primarily used by the males during the breeding season. They mate for life, though some males have two partners instead of being entirely monogamous.

Brown-headed cowbirds are the biggest threat to the Eastern phoebe, replacing the phoebe’s eggs with their own in the nest. However, the Eastern phoebe will still care for the eggs regardless.

Amazing Facts

• The name “Phoebe” may come from the symbolism associated with the Roman goddess of the same name.
• The flycatcher family is known for its own symbolism — diverting and deceiving enemies. The Phoebe specifically is symbolic of hidden knowledge and wisdom.
• Eastern phoebes are incredibly friendly, though they primarily keep to themselves.

Where to Find Eastern Phoebe

Eastern Phoebes are primarily migratory, breeding in eastern North America and wintering from the southeastern United States to Mexico. They may be found year-round in small numbers in parts of the southeastern U.S., but most populations migrate south for the winter. Don’t worry — the Eastern phoebes are notorious for returning to breed by the early spring, though some will even return by the start of March.

The easiest way to attract Eastern phoebe is to offer a nesting box or other areas to perch.

Nests

These birds like to build a nest in areas with plenty of support and overhead protection, often looking for barns, a nesting box, or another manmade structure. They also build near streambanks and rock outcrops. Males will sing their brief two-part song around this time, while the female builds the nest or nesting box from leaves, grass stems, moss, mud, and animal hair. They are one of the few animals that will keep their nest up and return to it each time they have another brood.

If a male has two mates, he will alternate between two nests to help with the care and protection of the young.

Scientific Name

The scientific name of these birds is “Sayornis phoebe.” It belongs to the Tyrannidae family under the Aves class.

The genus name — “Sayornis” — is a combination of the name that Charles Lucien Bonaparte chose for the Say’s phoebe (“Muscicapa saya”) and the word “ornis,” which means “bird” in Ancient Greek. The use of the word “phoebe” has been a credit to the noise that the male makes, though it may also be named for the symbolism of Roman moon-goddess Diana (a.k.a. Phoebe).

Appearance

These birds have a brownish-gray back with an off-white underbelly. Their beak is short and thin, accentuated by a dark hue. Their wingspan can reach up to 11 inches, though their entire length is about 6 inches, while they generally weigh between 0.6 to 0.7 ounces.

Evolution

Eastern phoebes belong to the suborder Tyranni and, as a result, are Passeriformes. Hence, they are also related to New Zealand wrens, which belong to the suborder Acanthisitti, and songbirds, which belong to the suborder Passeri. 

The suborder eastern phoebes belongs to is the most varied of the three groups, containing 5,158 species. The Passeri comes next with a total of 1,356 species. The Acanthisitti is the least varied, with just 4 species. A glimpse at the history of this wide, varied family reveals it first came on the scene about 50 million years ago.

The Acanthisitti was the first to diverge, while the Passeri and the Tyranni separated later. 

Behavior

Even with the Eastern phoebe mates, they primarily remain solitary birds. They won’t spend much time with their mate, and they will hunt from the same branch. Though they periodically fly after insects, they like to find a safe home and stay there.

Migration Pattern and Timing

If you want to get a glimpse of these birds, you’ll need to consider their migration. From September to November, they seek out a reprieve from the cold weather as they follow the migration of the species to Mexico and the southeast United States.

In the springtime, sometimes as soon as March, the passerine bird will fly north to breed and create nests.

Diet

As the Eastern phoebe perches on branches, it keeps a watchful eye and twitches its tail as it looks for insects to feed on. Most of the prey they catch is mid-air, though they don’t have to fly for long distances. They will go right back to the same branch while they wait for their next bite, and will hover as they pick at seeds and small fruits.

What does the Eastern phoebe eat?

The diet of this bird is primarily comprised of insects (like wasps, spiders, grasshoppers, bees, millipedes, ticks, seeds, and foliage.

Predators and Threats

Little is known about the predators that hunt the bird, though their eggs are at great risk. Predators like chipmunks, mice, snakes, and other birds will go after the eggs in their nest. Primarily, the female will try to defend the nest from these predators, but the male will also protect his family.

One of the great threats to this species is the brown-headed cowbird, but not because of hunting the Eastern phoebe. Instead, it will take the eggs from the nest of the phoebe and replace them with its eggs. The Eastern phoebe continues to take care of the eggs as if they were its own.

Reproduction, Babies, and Lifespan

During the breeding season, the bird molts its juvenile feathers for the first time, finding a monogamous mate. Once the birds build a nest, their clutch will range from 2 and 6 eggs. The female primarily cares for the nestlings for 16 days before they leave the nest.

Population

The IUCN considers these birds to be of least concern since there are over 35 million mature individuals. Conservation efforts for the Eastern Phoebe include habitat preservation, private lands programs, and research initiatives such as banding to monitor populations.
