Last Updated on April 4, 2023 by Susan Levitt

The black-throated blue warbler is a gorgeous bird that can be found throughout eastern North America. Every summer, these tiny creatures make an incredible journey from as far south as Central America to their breeding grounds in the north. It’s a journey that requires immense skill and determination, and it’s one that never fails to amaze birdwatchers around the world.

As well as being incredibly beautiful, the black-throated blue warbler is also an important part of the ecosystem. These birds play a vital role in helping maintain healthy forests and woodlands by preying on insects that can damage trees. They also help control insect populations, which can help reduce disease transmission among both humans and other animals.

Despite its importance, there is still much we don’t know about the black-throated blue warbler. We don’t know how many birds are left in the wild or what threats they face, but what we do know is that we need to protect them if we want to keep enjoying their beauty for future generations.

Scientific Name

The scientific name of the black-throated blue warbler is Setophaga caerulescens. It is a small bird, measuring about 4.5 – 5.5 inches in length and weighing around 0.3 ounces. Its back and wings are olive green, while its underside is yellowish with white spots on its breast and sides. The top of its head is a deep blue-black color, from which it gets its name. It also has two white wing bars and a white eye line that gives it an alert appearance. It has a short tail and long legs with large feet for hopping through trees. Transitioning to the next section, the black-throated blue warbler has an extensive geographic range across North America.

Geographic Range

Having established its scientific name –Setophaga caerulescens– we now turn to the geographic range of the black-throated blue warbler.

The warbler is found in North America and summers mainly in northeastern United States and southeastern Canada. During winter, they migrate south to Mexico, Central America, Caribbean islands, and northern South America. In other words, this species can be found all over the Americas!

Their breeding range includes:

  • Eastern North America:
  • Southern Canada from Ontario eastward
  • Northeastern United States from Maine southward
  • Central North America:
  • Great Lakes region from Minnesota eastward
  • Appalachians from Pennsylvania southward
  • Western North America:
  • Rocky Mountains from southern British Columbia southward

These birds can also be found along coastal areas during migration. Their habitats include deciduous forests, coniferous forests, shrublands and woodlots. With such a wide range, it’s no wonder that the black-throated blue warbler has become such a beloved species! Now let’s take a closer look at their preferred habitat.

Habitat

The Black-throated Blue Warbler is an amazing creature, with a habitat that stretches across the Eastern and Central United States. This bird lives in deciduous forests as well as coniferous woods, from Canada to Mexico and beyond. It can be found in wetlands such as swamps, bogs, ponds, streams and rivers. The warbler also nests on the ground or in shrubs close to the ground.

During migration season, the Black-throated Blue Warbler can be seen in or near residential areas and parks, giving us the opportunity to observe them up close. In springtime they often migrate through the Appalachian Mountains, while during fall migration they make their way down the Eastern Seaboard. All of this movement helps them stay close to their preferred habitat where they can find food sources that suit their needs. With a bit of luck we may even hear its beautiful song echoing through forests!

Having discussed its habitat, let’s now take a closer look at the diet and feeding habits of this lovely species.

Diet And Feeding Habits

In addition to their preferred habitats, the Black-throated Blue Warbler also has its own distinct diet and feeding habits. These birds forage for food in low shrubs, trees and vines, as well as on the ground. They have been known to hunt within a few feet of the ground, making them easily visible to humans.

The Black-throated Blue Warbler primarily eats insects such as caterpillars, beetles, ants and spiders. They will also eat some fruits and berries during certain times of the year. The warblers typically use an insectivore “gaping” technique to catch their prey which involves quickly opening their bill wide enough to catch bugs that are flying or crawling by. With this technique they can snatch their prey out of midair or off of leaves and branches very quickly. This ability allows them to be successful predators in a wide variety of environments. At the end of a successful day of hunting they may store some food items in crevices or bark on nearby trees for later consumption. With these techniques they are able to sustain themselves in their natural environment with ease.

This unique bird’s physical characteristics are just as remarkable as its habitat preferences and feeding habits.

Physical Characteristics

The black-throated blue warbler is a small songbird with a bright, vibrant plumage. It has a white belly, grey wings with two white wing bars, and a black face and throat. Its crown is mostly blue-grey or bluish-green in color, which makes it easily distinguishable from other warblers. Males are more brightly colored than females, especially during the breeding season.

On average the bird measures between four to five inches in length with a wingspan of six to seven inches. They weigh about nine grams and have an average lifespan of four years. During migration they fly at high altitudes, often up to 3,000 feet above sea level.

Breeding Behavior

The Black-throated Blue Warbler, with its vibrant blue plumage, is a sight to behold during the breeding season. Like many migratory birds, they return every spring to their breeding grounds in the eastern and northern parts of North America. To attract a mate, the males will sing an elaborate song from high in the treetops. During this time, they can also be seen performing courtship displays such as wing raising or flutter flight.

Mating pairs then construct a cup-shaped nest made of twigs and grasses and line it with fine fibers such as hair or fur. The female will lay two to five eggs that are pale blue or greenish white with reddish brown spots. The male and female take turns incubating the eggs for about two weeks until they hatch. Both parents will feed the young until they fledge at around 10 days after hatching.

Migration Patterns

After the black-throated blue warbler’s breeding season, they make their way to the Caribbean, Mexico and Central America for the winter months. The migration of this species is quite remarkable as they travel a great distance in a short amount of time.

PeriodAverage Miles per Day
Spring140
Summer110
Fall190

In comparison to other species, the black-throated blue warbler has one of the longest migrations with an average distance of 1,400 miles each way. This journey is filled with many obstacles such as unpredictable weather patterns, strong winds and predators. To help ensure their safe arrival at their wintering grounds, these birds migrate during daylight hours, taking advantage of thermals and air drafts created by warm ground surfaces or bodies of water.

As they come to a close on their spring migration back to their breeding grounds, the black-throated blue warbler is faced with yet another obstacle – human habitation. With more buildings and cities popping up along their migratory route, it has become increasingly difficult for them to make it back safely. With this in mind, it is important to monitor their conservation status in order to protect them from further harm.
