There are 25 species of New World Blackbirds spotted in North America, and 14 of these are spotted in New Brunswick, including Blackbirds, Orioles, Meadowlarks, Cowbirds, Grackles, and Bobolinks.
Of the fourteen species of blackbirds in New Brunswick, eight species are recognized on state checklists as regularly occurring, six species are considered rare or accidental, and three of these are also regarded as near threatened or vulnerable.
Although named “blackbirds,” they are, in fact, often brightly colored and are all the Icteridae family, which are common songbirds. They are classed as New World Blackbirds in North America to distinguish them from European Blackbirds which are part of the thrush family.
Due to their ability to devour vast quantities of seeds and grains, Blackbirds are considered an agricultural pest. In fact, Bobolinks have decreased by up to 60% in the last 50 years, in part due to persecution and declining habitat.
Whether you consider them noisy pests or intelligent and bright acrobats, there is no doubt that blackbirds are fascinating birds.
Male and female blackbirds can vary greatly in size and color, with males being up to 60% heavier than females and some having much brighter coloration.
Nests are a fascinating subject when it comes to blackbirds as some don’t build them at all, like cowbirds, which instead lay their eggs in other species’ nests for the host family to raise their young. Some orioles, on the other hand, build elaborate hanging nests.
Blackbirds can strongly force their bills open to allow them to prize open gaps to get to hidden food, but most birds cannot do this.
Many blackbirds migrate, especially from more northern areas, so check out the end of the article to see how common each blackbird is in summer or winter to help you know when to look for them.

14 Species of Blackbirds in New Brunswick
1. European Starling
European Starlings are an introduced species in New Brunswick that can be seen here all year and do not migrate. They appear in 23% of checklists submitted by bird watchers for the province.
European Starlings are not native but are now one of the most numerous songbirds. They are stocky blackbirds with iridescent purple, green, and blue tones.
- Sturnus vulgaris
- Length: 7.9-9.1 in (20-23 cm)
- Weight: 2.1-3.4 oz (60-96 g)
- Wingspan: 12.2-15.8 in (31-40 cm)
European Starlings live in all North America, except the north of Canada and Alaska.
They are considered a pest due to their aggressive behavior, and they fly in large, noisy flocks. You can often spot them perched in groups on the top of trees or flying over fields.
Starlings eat insects, including beetles, flies and caterpillars, earthworms, and spiders. They will also eat fruit, including cherries, holly berries, mulberries, Virginia Creeper, sumac, and blackberries, as well as grains and seeds.
Starling sounds: Warbles, whistles, and chatter are all part of the starling’s calls and songs, and they can even mimic other birds’ calls. They are often in noisy groups.
Nests of Starlings are often in buildings or nest boxes and made out of grass, pine needles, and other soft material. They have 3 – 6 eggs and take 12 days to hatch. Fledging is around three weeks later.
You can attract more European Starlings to your backyard feeders with black oil sunflower seeds, suet, cracked corn, and peanuts.
Fun fact: European Starlings gather in their thousands in a swirling, dancing mass in the skies just before dusk. This is called a murmuration and usually happens in winter in their native areas.
2. Common Grackle
Although they are near-threatened species, Common Grackles are the most frequently spotted blackbirds in New Brunswick and appear in 32% of summer checklists.
They can be spotted here during the breeding season, from March to July, and then they migrate. However, a few hang around all year and occur in 1% of winter checklists.
Common Grackles are blackbirds that are taller and longer tailed than a typical blackbird and with glossy iridescent bodies. Females are slightly less glossy than males.
- Quiscalus quiscula
- Length: 11.0-13.4 in (28-34 cm)
- Weight: 2.6-5.0 oz (74-142 g)
- Wingspan: 14.2-18.1 in (36-46 cm)
Common Grackles are resident all year in southeastern states, but those that breed in Canada and the Midwest migrate south.
Their habitat is varied and includes open woodlands, marshes, parks, and fields. They eat many crops but mostly corn and gather in noisy groups high up in trees. They will also eat garbage and so can be a nuisance.
Although they may gather in their millions, they are on the IUCN red list as near threatened due to the 50% decline in their numbers since the 1970s.
Common Grackle sounds: They make a series of croaks, squeaks, and whistles.
Nests of Common Grackles are made of twigs, leaves, and grasses are placed high up in conifer trees near water. They lay 1 – 7 eggs, which take about two weeks to hatch, and then the nestlings fledge in around another two weeks.
Attract Common Grackles to your backyard with mixed grain and seed sprinkled on the ground or on platform feeders.
Fun fact: Common Grackles may gather in their millions in winter to forage and roost, mixed in with other species of blackbird.
3. Red-winged Blackbird
Red-winged blackbirds are the second most frequently spotted blackbirds in New Brunswick in summer. They spend the breeding season here and appear in 23% of checklists in summer submitted by bird watchers. While most migrate south for the winter, a few remain in the province all year.

You can often spot Red-winged Blackbirds sitting on telephone wires. They prefer wet areas such as marshes but will nest in meadows and fields. Males will fiercely defend their territories in the breeding season, even attacking people that get too close to nests. In winter, they roost in large numbers into the millions.
Red-winged blackbirds eat mainly insects in summer and then seeds in the winter.
Red-winged Blackbird sounds: They make a short song that sounds like ‘Okelee’ and is drawn out at the end.
Nests of Red-winged Blackbirds are built near the ground in dense vegetation. The nest will be built by building a platform out of stalks and stems of nearby plants. This will have mud and wet leaves added to form a cup and then soft dry grass for the lining.
They lay 2 – 4 eggs, and the eggs take up to 13 days to hatch and then a further two weeks before the chicks can fledge.
Attract Red-winged blackbirds to your backyard with mixed grain and seeds spread on the ground. They will also feed on large tube feeders or platform feeders.
Fun fact: Male Red-winged Blackbirds will breed with up to 15 females and defend their territory from other males.
Bobolinks appear in 4% of summer checklists in New Brunswick and they can be seen during the breeding season from May until October.
Breeding Bobolink males are easy to identify as they are very unusual-looking birds, with white backs, black bellies, and a striking pale yellow patch at the back of their heads that looks like hair!
Females and non-breeding males in their winter plumage are quite different and rather plain in comparison. They are brown-streaked and with dark eyelines and stripes on their crowns.

- Length: 5.9-8.3 in (15-21 cm)
- Weight: 1.0-2.0 oz (29-56 g)
- Wingspan: 10.6 in (27 cm)
Bobolinks travel far from their wintering grounds in inland southern South America to their breeding grounds in northern US states and Canada, a journey of over 12,000 miles (20,000 kilometers). During migration, they can be spotted in eastern US states.
To find Bobolinks head to open grassland during the breeding season, and after breeding, they can be found in marshes and coastal areas.
They can often be spotted perched at the top plants looking for seeds and or on the ground looking for insects to feed their young.
Bobolink Sounds: Boblinks songs are a speedy mix of different pitches and tones that do not seem to follow a pattern. They also make several short ‘peek’ and ‘check’ calls.
Unfortunately, Bobolinks have declined by 65% since 1966, although the breeding population is 8 million, this is significantly less than it used to be. You can help by only mowing once a year after they have left your grassy fields and meadows.
Fun fact: Bobolink nests are on the ground, and the males make splendid displays of singing, flying, and fighting to attract females.
5. Brown-headed Cowbird
Brown-headed Cowbirds spend the breeding season in New Brunswick and appear in 1% of checklists. They are most likely to be spotted from April to August.

You can find Brown-headed Cowbirds in grasslands and fields but rarely in wooded areas. They forage on the ground, especially near grazing animals, waiting for them to kick up some food.
Grass and weed seeds make up most of their diet, but they also eat insects. They will also come to backyard feeders, and female cowbirds eat eggs and shells for calcium.
Brown-headed Cowbird Sounds: Their song has an almost water-like quality of a series of rapid, high-pitched whistles and gurgling sounds that only last a few seconds. They also make short calls.
Brown-headed Cowbirds do not build nests. They are often considered a nuisance as they destroy the eggs of smaller songbirds to lay their eggs in the nest and have the bird foster their chicks. They may also harass the host or destroy the nest if they remove their egg.
Fun fact: Are they brave or foolish? Brown-headed Cowbirds have also been known to lay their eggs in the nests of raptors!

How to Attract Blackbirds to Your Backyard
Blackbirds can easily be attracted to your backyard by making a few simple changes:
- Provide fruiting and berries plants such as blackberries, raspberries, cherries and plums
- Provide a fresh water source
- Hand nectar feeders for orioles
- Hang feeders for blackbirds containing cracked corn, millet and peanuts
- Do not tidy too much! By leaving beds a little messy this provides a great habitat for insects for blackbirds to eat.
