What Does a Cerulean Warbler Look Like?
Some birds like robins, goldfinches and cardinals are often sighted in backyards throughout America. Different hen species are way more unusual, and a quick glimpse of them can thrill birders for all times — and of those birds is the cerulean warbler.
Whereas cerulean warblers are particularly thrilling due to the beautiful blue feathers on the grownup male’s head, again, and wings, seeing these blue feathers can show a problem. After they’ve migrated to their breeding grounds these warblers have a tendency to stay to treetops, which suggests birders are likely to solely catch a glimpse of their white bellies. Females are duller than males, with higher plumage showing greenish reasonably than blue and lightweight yellow bellies.
Pamela Hunt, senior conservation biologist for New Hampshire Audubon, mentions the problem of seeing the feathers for which this warbler is called. “You hear them, they usually’re manner up in a tree someplace,” she says. “You’re looking for it, and also you wait, and also you wait, and finally you see it fly and also you see the white stomach. On the proper angle you may see the bluish-gray necklace throughout their throat, which is one among their cool diagnostic issues.”
Cerulean Warbler Vary and Habitat
This species winters in South America and passes by means of the japanese states throughout migration. They breed as far north as Wisconsin, Michigan and New York. Atypical guests to the West, the locations the place it’s best to search out them are typically tall forests or river valleys. “They’re a deeper forest species, they usually’ll unlikely be present in a residential space,” Pamela says. “They like their hardwoods.”
On the whole, discovering a cerulean warbler is usually a problem even for a devoted birder. Pamela maintains that the locations it’s simpler to find them are likely to require some climbing and neck-craning. “It’s a ‘hop on the prime of the timber’ species, but it surely’s arduous to search out, normally,” she says. “In sure locations they’re straightforward to search out, however they’re up within the mountains.”
Weight-reduction plan: What Do Cerulean Warblers Eat?
As is the case with most warblers, ceruleans dine totally on bugs, together with caterpillars and moths, and received’t seem at yard feeders.
Nesting Habits
Nests encompass three to 5 eggs and are constructed in tall deciduous hardwood timber in mature forests. Cerulean warblers increase one brood throughout every nesting season.
Numbers of this species are declining, so take additional care to not disturb them throughout nesting season.
Songs and Calls

Cerulean warblers give a buzzing, warbling tune that rises in pitch because it ends. If you happen to assume you’ve heard a cerulean warbler, you may want observe down the hen to ensure — the place their breeding ranges overlap, it might been a black-throated blue warbler.
“Those now we have in New England make a tune that’s just like the one the black-throated blue warbler makes,” Pamela says. “We’ve come to the conclusion in east-northern New England that you just can not conclusively say it’s a cerulean warbler except you’ve seen it.”
