Complete Canadian Birdseed Guide — Attract More Birds to Your Yard
Choosing the right birdseed is one of the most powerful things a Canadian backyard birder can do to attract a wide variety of species. The wrong seed in the wrong feeder in the wrong location will attract nothing but squirrels and house sparrows — but the right combination brings chickadees, finches, woodpeckers, nuthatches, and grosbeaks right to your window. At BIRDHOUSES.ca, we break down everything you need to know about birdseed in Canada, from the best seeds for specific species to safe feeding practices, suet, and seasonal timing across the country.
1. Black-Oil Sunflower Seed — Canada's #1 Birdseed
Black-oil sunflower seed is without question the single best all-around birdseed for Canadian backyard feeders. Its thin shell is easy for small birds to crack, its high fat and protein content provides excellent energy — especially important in cold Canadian winters — and an extraordinarily wide range of species will eat it. Black-capped Chickadees, White-breasted and Red-breasted Nuthatches, House Finches, Purple Finches, American Goldfinches, Pine Siskins, Common Redpolls, Evening Grosbeaks, Blue Jays, Downy and Hairy Woodpeckers, Dark-eyed Juncos, and many sparrow species all take black-oil sunflower readily.
If you can only stock one type of seed in your Canadian yard, black-oil sunflower is the answer. It can be offered in tube feeders, hopper feeders, platform feeders, and scattered directly on the ground for ground-feeding species. Buy in bulk bags of 10 to 20 kg for the best value — Canadian winters are long and a well-stocked feeder can go through several kilograms per week during cold snaps when birds are feeding heavily to maintain body heat.

Nyjer seed, also called thistle seed, is a tiny black seed imported from Africa and Asia that is the preferred food of several of Canada's most colourful finches. American Goldfinches — brilliant yellow in summer, olive-yellow in winter — are the primary target species for Nyjer feeders across most of Canada. Pine Siskins, Common Redpolls, Hoary Redpolls (in northern Canada), and occasionally Purple Finches also visit Nyjer feeders enthusiastically.
Nyjer must be offered in a specialized thistle feeder with very small ports — the tiny seeds fall out of standard feeder ports too quickly and are wasted. Sock feeders (mesh bags) are an inexpensive and effective way to offer Nyjer and allow multiple finches to cling and feed simultaneously. One important note for Canadian birders: Nyjer seed has a relatively short shelf life and loses its oil content — and therefore its appeal to birds — if stored too long. Buy in smaller quantities and store in a cool, dry location. If your Nyjer feeder is being ignored, try replacing the seed before assuming the birds aren't interested.
3. Safflower Seed — The Squirrel Deterrent
Safflower seed is a white, slightly bitter seed that is highly attractive to several desirable Canadian feeder birds while being largely ignored by two of the most common feeder pests — squirrels and European Starlings. Northern Cardinals (in southern Ontario and Quebec), Black-capped Chickadees, House Finches, Mourning Doves, and White-breasted Nuthatches all take safflower readily. For Canadian birders frustrated by squirrels emptying their feeders, switching partially or entirely to safflower in accessible feeders is one of the most effective non-mechanical deterrents available.
Safflower can be offered in any standard tube or hopper feeder and can be mixed with black-oil sunflower to create a high-value blend that still deters squirrels. It is worth noting that birds sometimes take a few days to a week to accept safflower if they haven't encountered it before — try mixing it with familiar sunflower seed at first and gradually increasing the proportion of safflower until the transition is complete.

White proso millet is the seed of choice for ground-feeding birds and is one of the most underrated seeds in the Canadian birder's toolkit. Dark-eyed Juncos — one of the most abundant and widespread winter feeder birds across Canada — strongly prefer millet. Native sparrows including White-throated Sparrows, White-crowned Sparrows, Fox Sparrows, and Song Sparrows all take millet readily, as do Mourning Doves, Common Redpolls, and American Tree Sparrows. Scatter white millet directly on the ground or on a low platform feeder beneath your main seed feeders to catch the hulls and attract ground feeders simultaneously.
A caution about commercial mixed seed: many inexpensive wild bird mixes sold at Canadian grocery and hardware stores are padded with large amounts of milo (red millet), wheat, and oats — seeds that very few Canadian birds will eat and that end up as waste on the ground, attracting rodents and promoting mould. Read the ingredient list before buying any mixed seed. The best mixes for Canadian feeders contain primarily black-oil sunflower, white millet, and either safflower or striped sunflower, with no milo, wheat, or oat filler.
5. Suet — Essential High-Energy Food for Canadian Winter Birds
Suet is rendered beef fat, usually mixed with seeds, nuts, insects, or fruit, and pressed into cakes that fit a standard wire suet cage feeder. It is one of the highest-calorie foods available to birds and is particularly important during Canadian winters when insects — the primary food source for many species — are unavailable and birds need maximum energy to survive frigid temperatures. Suet is the single best food for attracting woodpeckers to a Canadian yard: Downy Woodpeckers, Hairy Woodpeckers, Pileated Woodpeckers, and Northern Flickers all visit suet feeders regularly.
Beyond woodpeckers, suet attracts Black-capped Chickadees, White-breasted and Red-breasted Nuthatches, Brown Creepers, and occasionally warblers during migration. No-melt suet formulations are important for Canadian summers — standard suet cakes begin to melt and go rancid in temperatures above 10°C, which can be harmful to birds. In warm weather, switch to no-melt suet or take suet feeders down entirely until fall. During winter, standard suet cakes are perfectly safe and extremely effective. Suet should be offered in a wire cage feeder mounted on a tree trunk or post — the vertical orientation mimics natural foraging on bark and is most comfortable for woodpeckers and creepers.
6. Peanuts & Tree Nuts — Jays, Woodpeckers & Nuthatches
Shelled and unshelled peanuts are among the most calorie-dense foods you can offer at a Canadian feeder, and they attract some of the most charismatic species. Blue Jays will carry off unshelled peanuts one at a time and cache them for later — a single pair of jays can empty a peanut feeder in a morning. Offer unshelled peanuts on a platform feeder or in a mesh peanut feeder for jays. Shelled peanut pieces in a mesh or tube feeder are more accessible to smaller birds including Black-capped Chickadees, White-breasted Nuthatches, Downy Woodpeckers, and House Finches.
One important caution: never offer salted, flavoured, or roasted peanuts at bird feeders. Only plain, unsalted raw peanuts are safe for birds. Salt is harmful to birds at the quantities they would consume from salted snack peanuts. The same applies to other tree nuts — plain unsalted walnuts, pecans, and almonds are all safe in small quantities, but any seasoned or processed nut product should be kept away from feeders entirely.
7. When to Feed Birds in Canada — Seasonal Guide
A common question among Canadian backyard birders is whether to feed birds year-round or only in winter. The answer depends on your goals and location. Winter feeding — from October through April across most of Canada — is when supplemental feeding provides the greatest benefit to birds, helping them survive extreme cold snaps when natural food sources are buried under snow or ice. This is also when the greatest variety of species visits feeders, including irruptive northern species like Common Redpolls, Pine Siskins, and Evening Grosbeaks that move south into populated areas during years when their natural food crops fail in the boreal zone.
Spring and fall feeding is excellent for attracting migrating species passing through your area. Many birds that don't breed in your region will stop briefly at a well-stocked feeder during migration — Fox Sparrows, White-throated Sparrows, and Ruby-crowned Kinglets are common fall visitors to Ontario and Quebec feeders. Summer feeding is controversial — some ornithologists argue it creates dependency in adult birds, though research generally does not support this concern. The main genuine risks of summer feeding are attracting bears (in rural and suburban areas adjacent to bear habitat, feeders should come down by late April), promoting mould in uneaten seed during wet weather, and attracting rodents. If you feed in summer, use only fresh seed, clean feeders frequently, and take feeders in at night in bear country.
8. Safe Feeding Practices & Predator Protection
A bird feeder concentrates birds in a predictable location, which also makes them vulnerable to predators. Domestic and feral cats are by far the most significant predator threat at Canadian feeders — Environment and Climate Change Canada estimates that cats kill hundreds of millions of birds annually in Canada. Place feeders either very close to dense shrub cover (within 1 metre, so birds can escape instantly) or far enough from any cover that cats cannot stalk undetected (at least 3 metres from shrubs or structures). Keep feeders away from fences and low walls where cats can crouch and wait.
Window strikes are another serious hazard associated with feeders — birds flushed suddenly from a feeder by a predator or disturbance often fly directly into windows. Place feeders either within 1 metre of a window (so birds don't have room to build up fatal speed) or more than 10 metres away. Window collision deterrent products — decals, screens, and UV-reflective films — are effective and worth installing on any large window near a feeder. Keep the area under feeders clean by raking up hulls and spilled seed regularly — accumulated seed waste promotes mould, attracts rodents, and can harbour bacteria harmful to birds. Wash feeders with a dilute bleach solution every two weeks during heavy use periods.
