25 Species Of Warblers In Manitoba (ID, Song, Season Guide)

bay-breasted warbler

This guide will help you identify all the species of warbler that are regularly occurring in Manitoba with photo ID and descriptions, audio recordings of their songs, and fun facts, plus more.

Warblers are small migratory songbirds that travel long distances from as far as South America up to breeding grounds as far as Canada. They are active and often bright birds that rush through from breeding to wintering grounds in a flash of yellow and green and with a marvelous variety of songs.

North American warblers are known as wood-warblers as they can be found mainly in woodland and forests. You may also get what is known as warbler neck, which is a painful neck stiffness and tingling from looking up into the trees with your binoculars trying to spot them.

Warblers mainly eat insects, but they will often come to backyard feeders for seeds or mealworms. Find out the other species of birds that regularly visit Manitoba and print a free ID chart.

This guide will help you identify the types of warblers spotted in Manitoba that are classed as regularly occurring according to avibase and uses data collected from bird watchers on ebird to give real information about when these birds can be spotted.

For all of the warblers in this guide, you can hear their songs and get a guide to different song types of warblers, but you can check out this guide to 13 easy to recognize warbler songs to help.

Yellow-rumped Warbler Myrtle

Yellow-rumped Warblers can be spotted during the breeding season in Manitoba, but their numbers increase during migration from April to May and from September to October. They are recorded in 20% of summer checklists and up to 42% of checklists during migration.

Yellow-rumped Warblers are gray with flashes of yellow on the face, sides, and rump and white in the wings. Females may be slightly brown, and winter birds are paler brown with bright yellow rumps and sides turning bright yellow and gray again in spring.

There are two subspecies, the Myrtle Warbler of the eastern US and boreal forests of Canada, which lacks the yellow throat, and Audubon’s Warbler of the west, which also has more white in the wings.

  • Setophaga coronata
  • Length: 4.7-5.5 in (12-14 cm)
  • Weight: 0.4-0.5 oz (12-13 g)
  • Wingspan: 7.5-9.1 in (19-23 cm)

Yellow-rumped Warblers breed predominantly in Canada and parts of the Rockies and the Appalachian mountains.

During migration, they can be seen in the Midwest before overwintering in southern and southwestern US states and the Pacific Coast and into Mexico and Central America.

You can find Yellow-rumped Warblers in coniferous forests, especially during the breeding season. During winter, they can be found in open areas with fruiting shrubs. In summer, they eat mostly insects and on migration, and in winter, they eat mostly fruit, including bayberry and wax myrtle. 

Yellow-rumped Warbler Song:

Canada Warblers are similar in appearance to the Magnolia Warbler and have a similar range. However, they are grayish-black on the back, and the black ‘necklace’ in the males, does not extend over the belly, only over the chest. They have yellow chests, bellies, and throats.

Females and immatures are similar but paler on the back and with a less prominent ‘necklace.’

  • Cardellina canadensis
  • Length: 4.7-5.9 in (12-15 cm)
  • Weight: 0.3-0.5 oz (9-13 g)
  • Wingspan: 6.7-8.7 in (17-22 cm)

Canada Warblers breed in Canada and northeastern US states, but they can also be seen during migration across the eastern half of the US. They winter in western South America.

You can find Canada Warblers in rhododendron-filled conifer forests or aspen and poplar forests, foraging for insects and spiders. They are difficult to find as their numbers have been declining.

Nests of Canada Warblers are built near the ground in shrubs or ferns and woven into a cup from grass, bark, leaves, and other plant material. They lay up to six eggs, which take about twelve days to hatch and a further eight days for the young to leave the nest.

Fun Fact: Canada Warblers are flying machines that travel over 3000 miles each way from their winter to summer grounds.

20. Bay-breasted Warbler

Bay-breasted Warblers are not very common in Manitoba, but they are usually spotted during summer from May to October.

Bay-breasted Warbler males are gray and black-streaked on the back and have reddish-brown crowns and breasts. They are white underneath and have black faces with a white patch behind their faces.

However, they are different colors during the breeding season than after the fall molt, and they look similar to Blackpoll Warblers in the fall.

Female Bay-breasted Warblers are similar but with less reddish-brown coloring and no black on the face when in breeding plumage. Non-breeding females and juveniles have yellowish-green heads, necks, and upper backs.

  • Setophaga castanea
  • Length: 5.5 in (14 cm)
  • Weight: 0.3-0.6 oz (10-17 g)
  • Wingspan: 7.9-8.7 in (20-22 cm)

Bay-breasted Warblers breed in Canada and can be seen over eastern US states during the migration. They spend the winter in South America.

You can find Bay-breasted Warblers mostly in spruce and fir forests in the breeding season, eating spruce budworm, but they can be seen in any forest type during migration. In winter, they also eat berries.

Nests of Bay-breasted Warblers are built mainly by females on lower branches of spruce or fir trees. They use twigs and bark with dried grass, woven in and held together with spider silk. They lay up to seven eggs.

Fun Fact: Bay-breasted Warblers can consume over 10,000 budworms per hectare in around 40 days, and there are more nests in budworm outbreak areas.

21. Black-throated Green Warbler

Black-throated Green warbler (Setophaga virens)

Black-throated Green Warblers are seen in Manitoba from May to September in the south of the province.

Black-throated Green Warblers are small yellow songbirds with a yellow face and head and olive-yellow back. They have black streaking on the sides and wings and are whitish underneath. Males have large black patches on their throats, but on females and juveniles, this is smaller.

  • Setophaga virens
  • Length: 4.3-4.7 in (11-12 cm)
  • Weight: 0.3-0.4 oz (7-11 g)
  • Wingspan: 6.7-7.9 in (17-20 cm)

Black-throated Green Warblers can mostly be seen during their long migration over the eastern US up to their breeding grounds in northeastern US states and Canada. Their winter grounds are in Mexico, northern South America, and the Caribbean.

You can find Black-throated Green Warblers high up in forests eating insects, and their black throat is an easier way to tell them apart from other small yellow birds.

Nests of Black-throated Green Warblers are in small trees and close to the truck. The nest is made from twigs and bark woven together with spiders’ webs and lined with animal hair, moss, and feathers. They lay around four eggs, which take twelve days to hatch and a further ten days for the young to leave the nest.

Attract Black-throated Green Warblers to your backyard with mature trees.

Fun Fact: Male Black-throated Green Warblers can sing over 400 times in an hour and perform a ‘gloating’ flight when they have chased off rivals.

22. Connecticut Warbler

Connecticut Warblers can be spotted in Manitoba during summer from May to September.

Male Connecticut Warblers have gray heads and throats, white eye-rings, olive-green backs and wings, and yellow bellies. Females have lighter coloring, with olive-brown heads and backs, a whitish throat, and a yellow belly. Juveniles are generally yellowish-olive. 

  • Oporornis agilis
  • Length: 5.5 inches (14 cm)
  • Weight: 0.5 oz (14 g)
  • Wingspan: 8.75 in (22 cm)

Connecticut Warblers breed in southern Canada and the northern Great Lakes and can be seen migrating across the Midwest and down to Florida on their way to South America for winter.

You can find Connecticut Warblers in remote areas, such as bogs with deciduous woods with poplar, spruce, tamarack, or aspen. When migrating, they select low, wet woods and damp thickets. 

Connecticut Warblers are skulkers. They spend their time foraging under dense or low leafy vegetation. They usually search for spiders, snails, and caterpillars, picking among dead leaves and hopping between branches.

Nests of Connecticut Warblers are made of grass and often hidden in thick clumps of moss. The female lays three to five eggs that take around twelve days to hatch. 

Fun Fact: Connecticut Warblers are elusive birds and have different migratory routes, which makes it hard for scientists to learn more about them.

23. Golden-winged Warbler

Golden-winged Warblers are near-threatened species in Manitoba that can be spotted here during summer, mainly in the south of the province.

Golden-winged Warblers are small, striking, and attractive birds. Males have a yellow crown, black bill and throat, a black mask that extends from the bill to behind the eyes, and a white head. Their bodies are whitish-gray overall, with no patterns. They have yellow wing patches.

Female Gold-winged-warblers are similarly patterned, except that they have a duller coloring. Instead of white heads, like the males, theirs are grayish. Even their eye masks are gray instead of black. Although juvenile males have white heads like adult males, they share a dull color with females. 

  • Vermivora chrysoptera
  • Length: 4.75 – 5 inches (12 – 13 cm)
  • Weight: 0.3 oz (9 g)
  • Wingspan: 7.75 – 8.25 inches (20 – 21 cm)

Golden-winged Warblers breed in the Midwest and east to the Atlantic Coast. They can be seen migrating across eastern US states to Mexico, Central and South America.

You can find Golden-winged Warblers in “early successional habitats”, like abandoned fields and pastures. Scrubby, shrubby areas of evergreen forests are also breeding grounds for them. 

Golden-winged Warblers tend to forage in hanging dead leaves that are common in regenerating forest communities. They feed on insects, spiders, and caterpillars they find under dead leaves and may sometimes hang upside down from branches to feast on larvae or pupae.

Nests of Gold-winged Warblers are often concealed low in a bush or in a concealed cup nest on the ground. Sometimes, they may also be hidden near the base of a tree. Females make the nests using bark and grass and then line them with animal fur. Females lay four to seven eggs, and they incubate them for about ten days. 

Fun Fact: Golden-winged Warbler parents use decoy feeding grounds to protect their young by confusing humans. 

24. Northern Parula

Northern Parulas are not spotted very often in Manitoba, but they spend the breeding season in the south of the province from May to September.

Northern Warblers are a colorful contrast of blueish-gray and yellow. They are bluish-gray on the back with a yellow patch on the back and with two white wingbars.

Males have a chestnut band that separates the yellow throat and chest that adorns both males and females. Females are paler than males and lack the chestnut band. Juveniles are paler.

  • Setophaga americana
  • Length: 4.3-4.7 in (11-12 cm)
  • Weight: 0.2-0.4 oz (5-11 g)
  • Wingspan: 6.3-7.1 in (16-18 cm)

Northern Parulas breed in the eastern US states and southeastern Canada before heading to Central America and the Caribbean for winter. They may remain for winter in southern Florida.

You can find Northern Parulas feeding on insects high up in deciduous forests.

Nests of Northern Parula are made in long clumps of lichen and moss that drape from the branches. The best way to spot them is by looking up at large clumps of hanging moss in the summer.

Attract Northern Parula to your backyard with native trees and shrubs, especially those with berries, and leave brush piles for insect-friendly areas.

Fun Fact: Northern Parula females do the rearing of young, including incubation of the eggs and feeding them. Males sing and remove fecal sacs!

25. Pine Warbler

Pine Warblers are not commonly seen in Manitoba, but you might spot some migrating across the province.

Pine Warblers are small plump yellow birds with olive backs, white lower bellies, and gray wingbars. Females can appear browner and have more white on the belly.

  • Setophaga pinus
  • Length: 5.1-5.5 in (13-14 cm)
  • Weight: 0.3-0.5 oz (9-15 g)
  • Wingspan: 7.5-9.1 in (19-23 cm)

Pine Warblers breed in northeastern US states before heading to southeastern US states. Some remain all year in southeastern US states.

You can find Pine Warblers in pine forests, as their name would suggest, often high up in the trees. They eat caterpillars, beetles, spiders, and other insects and larvae, and when the weather is colder, they will eat fruit and seeds.

Pine Warbler Song:

Nests of Pine Warblers are, as you would expect, in pine trees! They are made from twigs, bark, pine needles, and grass, bound with spider silk and lined with feathers and animal hair. They lay up to five eggs which take up to two weeks to hatch and another ten days for the young to leave the nest.

Attract Pine Warblers to your yard with tube feeders and platform feeders with millet, cracked corn, sunflower seeds, peanut hearts, and suet. Also, plant native fruits and vines such as bayberry, grape, sumac, and Virginia creeper.

Fun Fact: Pine Warblers are one of the only warblers to eat seeds mainly, and so you are more likely to see them at backyard feeders.

How To Attract Warblers To Your Backyard

Warblers are not as common as other songbirds to backyard feeders, but there are ways you can attract these melodious songbirds to your yard:

  1. Provide trees if your yard is big enough
  2. Leave brush piles and don’t be too tidy to ensure an insect friend habitat
  3. Don’t use pesticides or herbicides to ensure insects are available and birds do not consume any
  4. Provide a clean water source
  5. Offer mealworms, preferably live ones but dried if not
  6. Provide bird feeders with sunflower seeds, peanut hearts, and suet
