Behavior

The Blackpoll Warbler is a legendary athlete in the avian world, known for one of the most grueling migrations of any songbird. During the spring and fall, these tiny travelers can be found flitting through the mid-to-upper canopy of deciduous and coniferous trees. They are restless foragers, constantly moving through foliage to glean insects. While they are somewhat secretive during their breeding season in the boreal forest, they become more visible in backyards during migration as they stop to refuel.

Socially, they are usually solitary but will frequently join mixed-species foraging flocks during their travels, often seen alongside Chickadees or other Warbler species. They are best known for their incredibly high-pitched, rhythmic song that sounds like a series of fast, thin 'tsit' notes. Because their song is at such a high frequency, it can be one of the first sounds older birdwatchers lose the ability to hear.

Camera Tips

To capture a Blackpoll Warbler on your backyard camera, you need to focus on their two biggest needs during migration: water and fuel. Because they typically stay high in the trees, your best chance of a clear shot is at an elevated birdbath. Position your camera 3-4 feet away from the water source at eye level with the basin. These birds are highly attracted to the sound of moving water, so adding a solar-powered dripper or mister to your birdbath can be the 'magnet' that brings them down from the canopy into your camera's field of view.

Since these warblers are incredibly fast and 'twitchy'—rarely staying still for more than a second—set your AI camera to its highest trigger speed or use a video-first setting. If your camera allows for manual shutter speed control, a setting of 1/1000th of a second or higher is ideal to freeze their wing movement. During the fall, placing a camera near native berry-producing shrubs like Pokeweed or Dogwood can also yield fantastic results, as they will spend more time stationary while feeding on fruit than they do while hunting insects.

Timing is everything with the Blackpoll. In the fall, they are preparing for a 72-hour non-stop flight over the Atlantic, so they feed aggressively in the early morning hours. Ensure your camera is positioned to avoid direct morning sun glare, which can wash out the subtle streaking on a non-breeding bird's plumage. If you are using a trail camera in a wooded area, look for 'drip puddles' after a rainstorm, as these are natural magnets for migrating warblers looking to bathe and drink before their evening departure.

Similar Species

Species that look similar or are commonly confused with Blackpoll Warbler.

Black-and-white Warbler

Look for a striped crown and a behavior of creeping along tree trunks rather than the Blackpoll's solid cap and branch-hopping.

Bay-breasted Warbler

In fall, these are very similar 'confusing fall warblers,' but the Bay-breasted has buff-colored flanks and dark legs, whereas the Blackpoll has pale underparts and orange-yellow legs.

Frequently Asked Questions

Blackpoll Warblers are most active in the early morning, from sunrise until about 10:00 AM. This is when they forage most intensely to replenish energy lost during their overnight migratory flights.
The most effective way to attract them is by providing moving water, such as a birdbath with a mister or dripper. They are also drawn to native trees like oaks which host the insects they eat, and berry-producing shrubs in the fall.
Their diet is mostly comprised of insects and spiders gleaned from leaves. During the fall, they supplement this with fat-rich berries to fuel their long-distance overwater migration.
They are common passage migrants in suburban areas across the Eastern and Central US. While they don't nest in suburbs, they frequently stop in residential yards with mature trees during May and September.
A breeding male Blackpoll has a solid black 'cap' and white cheeks, while the Black-and-white Warbler has a striped crown and is often seen creeping up and down tree trunks like a nuthatch.
