Feeding Birds in Southern Canada

Canadian feeding is a winter discipline. Fat, open water and a feeder that still works at -20°F (-29°C) matter more than variety, and the year's most interesting birds arrive from the boreal forest without warning.

Canadian feeding is dominated by one number: how cold it gets overnight. A small bird burns a large share of its fat reserves in a 16-hour winter night, and everything about a good setup here follows from making that fat easy to replace at dawn.

That is why sunflower, peanuts and suet carry the winter and why cheap filler mixes are close to worthless in January. It is also why open water, which is genuinely scarce for months at a time, often outperforms any feeder in the yard.

Temperatures on this site are given in °F with °C in parentheses, though most Canadian readers think in °C and can safely ignore the first number. This guide covers the birds, the cold, the water, the boreal finch irruptions that make some winters remarkable, and the bear rules that vary from one town to the next.

Where this guide applies#

This page covers the populated southern band of Canada: the Maritimes, southern Quebec and Ontario, the settled parts of Manitoba, Saskatchewan and Alberta, and southern British Columbia. It is a wide strip with real internal differences, and the boundaries below are approximations.

• Southern Ontario, Quebec and the Maritimes feed much like the Northeast and the Midwest, with a longer and colder winter.
• The Prairies share the open-country species and wind problems of the Great Plains, with far harder cold.
• The Canadian Rockies and interior BC follow the Mountain West pattern, bears included.
• Coastal southern BC is mild and wet and behaves like the Pacific Northwest, including year-round Anna's hummingbirds.

Anything north of that band, in the boreal forest proper, is a different exercise and mostly outside what this page covers.

The winter finch forecast#

Every fall, an annual forecast of northern finch movements is published, a tradition long associated with Ontario birders. It looks at the cone crops on spruce, pine, birch and other trees across the boreal forest and predicts which species will stay north and which will be pushed south in search of food.

This matters practically. In a flight year, feeders in southern Canada can host common redpolls in flocks of dozens, pine siskins in numbers that empty a nyjer feeder in a day, evening grosbeaks, pine grosbeaks and Bohemian waxwings. In a good cone year, you may see almost none of them.

If the forecast calls for a flight, the useful preparation is more sunflower and nyjer capacity and a plan for the mess and the cleaning load a big finch flock brings. Dense flocks raise disease risk, so read salmonella outbreaks at feeders before an irruption winter, not during one.

Birds at a southern Canadian feeder#

American tree sparrows are the winter sparrow of much of this range, and Bohemian waxwings arrive in roving flocks that ignore feeders and strip mountain ash and crabapples instead.

Feeding in deep cold#

At -4°F (-20°C) and below, the calculation changes. Birds are not choosing between foods, they are trying to replace overnight fat loss before the next night.

• Fat first. Suet and peanuts alongside sunflower. Skip mixes padded with milo and wheat, which have low fat and get raked onto the snow.
• Sunflower hearts earn their price in winter. No shell to crack means less energy spent and less time exposed, which matters at these temperatures.
• Be reliable during cold snaps and storms. Consistency in the worst week of the year is worth more than year-round perfection.
• Feed at first light. Fill in the afternoon so everything is stocked before dawn, when birds most need it.

The full reasoning is in feeding birds in extreme cold and best high-energy foods for cold weather.

Open water when everything is frozen#

For four to five months, standing water in much of southern Canada is ice. A heated bird bath is the highest-impact addition most Canadian yards can make, and it draws species that never touch a seed feeder.

Use a bath with a built-in thermostat or a de-icer designed for the purpose, on an outdoor-rated circuit. Keep it shallow, no more than 2 inches (5 cm), and add stones for grip. Never add antifreeze, salt or glycerin, which are dangerous to birds. Setup detail is in winter water and heated bird baths.

Snow, ice and feeder hardware#

Snow does more damage to a feeding operation than cold does.

Tube feeders with wide caps and weather domes keep ports usable in blowing snow. Platform feeders need to be brushed off after every snowfall or they simply disappear. Hanging a feeder under an eave sounds clever until a snow slide off the roof takes it down, so site it clear of the drip line.

Ground-feeding birds need a cleared patch. Shovel a square near cover and restock it, which is worth more to juncos and tree sparrows than another hanging feeder. And keep a brush pile or dense conifer nearby: shelter from wind is as valuable as food, as covered in brush piles and cover.

Bear rules vary by province and municipality#

Bears are a live issue across most of Canada, not only in the mountains. Black bears are active from roughly April until they den in late fall, and a feeder is one of the classic attractants that brings them into towns.

There is no national rule. Provinces set wildlife legislation, and many municipalities add bylaws that restrict or prohibit bird feeders during bear season, sometimes with fines attached. Communities in British Columbia, Alberta, Ontario cottage country and elsewhere are particularly strict. Check your own municipality's bylaws each spring.

Where feeders are restricted, a bird bath is almost always still permitted and remains a strong draw through summer. Nectar feeders brought inside at night are a common compromise, though they are not risk-free. The broader precautions are in bird feeders and bears.

A southern Canadian feeding calendar#

• December to February. The core season. Sunflower, hearts, peanuts and suet, plus a heated bath. Watch for irruptive finches.
• March to April. Feeders still busy, then bear season starts in much of the country. Check local rules and plan to take seed down where required.
• May to June. Hummingbirds arrive over a window from late April into mid-May in the east. Orioles pass through and take orange halves and jelly. Natural food takes over quickly.
• July to August. Quietest stretch. Water and nectar carry the yard.
• September to November. Migration, then the rebuild. Once bears den, put seed feeders back and have them running before the first hard freeze, using the approach in fall bird feeding.

A setup that works through a Canadian winter#

• A tube of black oil sunflower with a weather dome, plus a second tube of hearts or nyjer in irruption years.
• A suet cage, ideally the upside-down type, and a peanut feeder for jays and nuthatches.
• A shoveled ground patch near cover, restocked after each snowfall.
• A thermostatically heated bath, running from first freeze to thaw.
• Feeders down in spring where bear bylaws require it, with the bath left running.

Clean feeders monthly through winter, more often in an irruption year when finch flocks concentrate. The method is in how to clean a bird feeder.
