Feeders and nest boxes attract birds, but native plants are what keep them coming back. A garden planted with species native to its region produces food continuously — berries, seeds, nectar — and hosts insects that insectivorous species eat. This food cycle is difficult to replicate with exotic ornamental species.

Why Native Plants Are More Effective

Canadian migratory birds evolved with plants from their home territory. Relationships between plant and animal species developed over thousands of years: fruiting often coincides with migration periods, and insects linked to native plants match birds' nutritional needs.

Ornamental cultivars, even derived from native species, may produce fewer berries or host fewer insects than natural varieties. Double flowers, for example, offer little or no accessible nectar.

Berry-Producing Plants

Serviceberry (Amelanchier spp.)

Serviceberry is among the first shrubs to produce berries in spring, often in June in central provinces. Its blue-violet fruit is eaten by cedar waxwings, American robins, warblers, and many sparrows. Canada serviceberry (Amelanchier canadensis) and saskatoon berry (Amelanchier alnifolia) are present in most provinces.

Common Elderberry (Sambucus canadensis)

Clusters of black elderberries ripen in August and September, during autumn migration. This shrub can reach 3 to 4 metres and produces abundantly even in partially shaded areas. More than 40 bird species in North America are documented as consuming its berries.

Red-Osier Dogwood (Cornus sericea)

Suited to wet areas and shorelines, red-osier dogwood produces whitish berries in August–September. Its red stems stand out in winter. It is particularly favoured by thrushes, waxwings, and blackbirds.

Highbush Cranberry (Viburnum trilobum)

Also called cranberrybush viburnum, this native Canadian shrub produces red berries that persist into winter, offering a late food resource for species that winter in Canada or migrate late. Its berries are eaten by cedar waxwings and blue jays.

Seed-Producing Plants

Wild Sunflower (Helianthus annuus var. sauvage)

Wild sunflower species produce smaller but more numerous heads than cultivated varieties. Their seeds are favoured by American and lesser goldfinches, sparrows, and siskins. Leaving stems standing in autumn lets birds feed directly on the plant.

Black-Eyed Susan (Rudbeckia hirta)

Black-eyed Susan is a native herbaceous plant whose seeds are eaten by sparrows and finches in autumn. It integrates easily into mixed beds and self-seeds.

Native Grasses

Grasses such as prairie dropseed (Sporobolus heterolepis) or switchgrass (Panicum virgatum) produce fine seeds eaten by juncos, sparrows, and finches. They also offer ground-level cover for birds feeding on the ground.

Insect-Supporting Plants

Native Oak (Quercus spp.)

Oaks host a particularly high number of native caterpillar species. These caterpillars are a crucial food source for many warblers, vireos, and flycatchers in migration. A single oak can contribute significantly to feeding insectivorous birds passing through a property.

Pin Cherry (Prunus pensylvanica)

This modest-sized tree produces small red cherries favoured by migrants and hosts many insects on its bark and foliage. It grows quickly and suits medium-sized properties.

Layout Tips

Vary Vegetation Layers

A bird-friendly garden includes at least three layers: canopy trees, mid-height shrubs, and herbaceous plants or ground covers. This vertical structure reproduces natural habitat diversity and attracts different species.

Avoid Pesticides

Pesticide use — even products presented as low impact — reduces insect populations that insectivorous birds depend on. Systemic insecticides integrated into seed can persist in pollen and nectar.

Leave Part of the Garden Natural

An unmown zone with tall grasses and hollow-stemmed plants offers habitat for insects that nest in soil or plant stems. These natural gardening areas are recognized in several Canadian municipalities, which have amended bylaws to allow them.

Where to Find Native Plants in Canada

Specialist native plant nurseries exist in all provinces. Organizations such as Ontario Nature or Nature Québec publish lists of local suppliers. Community garden exchanges are also a frequent source of region-adapted native plants.

Fruiting Calendar by Province

Fruiting periods vary by province, influenced by latitude and local climate.

  • British Columbia: serviceberry (May–June), elderberry (August–September), dogwood (August–October)
  • Ontario: serviceberry (June), elderberry (August–September), highbush cranberry (September–October)
  • Quebec: serviceberry (June–July), elderberry (August), viburnum (September–November)
  • Prairie Provinces: saskatoon berry (July), sand cherry (August)
  • Atlantic Provinces: red elderberry (July–August), red-osier dogwood (September)
