The 2023/2024 Winter Finch Forecast is Here!
It's looking like we may have a pretty good birding season ahead! Redpolls and Pine Siskins are likely to make appearances in the region this winter, Purple Finches may also be more abundant later into the season as natural food crops deplete.
Hopefully we are lucky enough to get large flocks of redpolls and siskins - they are so much fun to watch and listen to! Keep a close eye on your feeders for the odd one mixed in with flocks of goldfinches, they can be difficult to tell apart from a distance.
At bird feeders, many of the species listed in the report enjoy foods such as WBU No-Mess Blend, WBU Finch Blend, Sunflower Chips, WBU Supreme Blend, Black Oil Sunflower, Nyjer and Safflower.
Are you looking forward to winter birding? We certainly are! 🐦
GENERAL FORECAST 2023-24
This year’s Winter Finch Forecast will be a mosaic of movements differing in intensity and area across the species.
Forecasts apply mainly to Ontario and adjacent provinces and states. Three irruptive non‐finch passerines whose movements are often linked to finches are also discussed.

The boreal forest has generally a poor to below average cone crop this year that is bookended with bumper cone crops in Alaska and Newfoundland. Coastal areas to the south on the Atlantic and Pacific coasts have above-average cone crops, which seem to quickly drop in quality as one progresses inland. Large areas of the boreal forest across interior Canada have a very poor to poor cone crop. Only the Alder crop appears to be above average across the boreal forest.
The southern edge of the eastern boreal forest from Lake Superior eastward to the Atlantic coast and southward to the northeastern states has extensive areas of bumper Eastern White Pine crop. This area also contains an above-average deciduous tree seed crop and excellent fruiting crop.
There is a widespread good crop of Mountain Ash berries from Lake Superior eastward. However, areas in Labrador appear patchy away from the coast. Most Pine Grosbeaks should remain in the eastern boreal forest with some flight into their traditional wintering areas in southeastern Canada and northern New England states.
West of Lake Superior, the Mountain Ash crop through the boreal forest westward generally appears below average with some areas of good crops. Areas in the upper Midwest states and cities in western Canada may see flocks of hungry grosbeaks searching for fruiting ornamental trees and well-stocked feeders with black oil sunflower seeds.
The movement of this species is one of opposite extremes this fall. Strong southward flights have been seen by mid-September at the Hawk Ridge Hawkwatch near Duluth, Minnesota. While to the east at Observatoire d’oiseaux de Tadoussac, Quebec, there has been very little movement. Northwest of Duluth into northwestern Ontario and Manitoba, the pit fruit and cone crop is below average, with reported areas of absence of food. While east of Lake Superior, the pit and deciduous fruit crops are above average and widespread.
In the east, many Purple Finches are expected to overwinter in southern Canada and the northeastern United States. Meanwhile from the upper Midwest states westward, there should be a stronger flight southward through the middle of the United States. Don’t be surprised if, as winter progresses, a late movement in January and February occurs into the Carolinas as eastern crops are depleted.
At feeders, they prefer black oil sunflower seeds.
COMMON AND HOARY REDPOLLS
Across the whole boreal forest, a good Alder crop has been reported. However, in the same areas, the spruce and birch crops are poor to below average. Expect a moderate flight south out of the boreal forest. Watch for redpolls on birches, in weedy fields and at bird feeders offering nyjer® and black oil sunflower seeds. Watch for Hoaries in flocks of Common Redpolls. See the link below for photos and identification marks of Common and Hoary Redpoll subspecies.

Significant numbers of siskins have started to leave the boreal forest in mid-September, with 1000s reported daily at migration monitoring stations from Duluth, Minnesota eastward to Tadoussac Quebec. With the poor White Spruce crop in much of the boreal forest, there should be a moderate to possibly strong flight of siskins southward this fall. This entertaining species prefers nyjer® seeds in silo or sock feeders.
With poor to absent cone crops reported across the interior boreal forest away from Alaska and Newfoundland, noteworthy movements of White-winged Crossbills have already occurred eastward to the Maritime Provinces and northeastern states since June. The excellent spruce crops in Alaska and Newfoundland have drawn many crossbills away from the interior. As remaining crossbills exhaust the below-average cone crop within the boreal forest, expect nomadic movements of small flocks of crossbills to come south during the winter in search of food. Thus, additional movements may be seen this winter into areas like southeastern Canada and the northeastern states, and westward into upper Midwest States and southern Manitoba as they look for suitable cone crops.
We may even see White-winged Crossbills away from forests, using heavy crops on planted native and ornamental spruces within urban environments.
As written above there is an excellent and widespread Eastern White Pine cone crop in place, and Type 12s have been around in their usual areas in the northeastern states since June-July.
During the middle of July however, Types 2 and 4 started invading the Great Lakes area, Ontario, Maritime provinces, and the northeastern states from across the continent, and there are growing subtle signs that Type 3 might be coming eastward as well. These types will all be hitting the bumper Eastern White Pine crop until it is exhausted (the White-winged Crossbills will probably hit it too). Birds will also be found in the remaining Red and White Spruce crops through fall and into early winter.
Once the calendar flips to 2024, will the Eastern White Pine crop be enough to hold birds and possibly initiate breeding, or will they be on the scramble looking here there and everywhere for food? As we get into the heart of winter, be sure to check your local patch of pitch, red, jack and Japanese black pines (aka the “hard pines”) for Type 12 and likely other types like large-billed Type 2 that will come south into coastal area pitch pine. Overall, expect crossbills to turn up in widespread areas in the east as winter progresses and turns into spring. Type 1 will be in the mix in interior areas as well.
The Red Crossbill types are usually impossible to identify without recordings of their flight calls. Recordings can be made with a smartphone and identified to type. Matt Young ([email protected]) will identify types if you email him your recordings or upload them to an eBird checklist. Recordings uploaded to eBird checklists are deposited in the Macaulay Library. See the link below for Red Crossbill call types.
Eastward from Lake Superior is a bumper crop of fruit on Chokecherry, and above-average berry and deciduous seed crops. With this diverse and widespread food source available in the east, expect most birds to remain in the boreal forest and adjacent areas of Central Ontario, southern Quebec, the Maritime provinces, New England states, and New York this winter.
Evening Grosbeaks in northwestern Ontario westward should move out of the boreal forest, looking for feeders in towns or suitable food sources further south. Evening Grosbeaks in the mountains of western Canada may move southward as well.
At platform feeders, Evening Grosbeaks prefer black oil sunflower seeds. Evening Grosbeaks will look away from feeders for maple and ash trees still holding seeds. See the links section below for Evening Grosbeak call types eBird article and The Evening Grosbeak Road to Recovery Project.
THREE IRRUPTIVE PASSERINES
Movements of these three passerines are often linked to the boreal finches.
In eastern North America, the deciduous tree crop appears above average, so expect a small to maybe moderate flight this fall. With the poorer crops west of Lake Superior, there should be a moderate flight of Blue Jays southward.
Populations in the boreal forest should have small flights this year. Balsam Fir in the boreal forest, which is not infested with Spruce Budworms, has a good cone crop. This crop should hold many nuthatches closer to home this winter.
Most Bohemians will likely stay in the north because native Mountain Ash berry crops are good, and other berry crops range from fair to good across the eastern boreal forest. Lake Superior westward should see more widespread movements of waxwings. In the east, small numbers will probably arrive mid to late winter in traditional areas from Central Ontario eastward into the Maritime provinces and northern New England as winter progresses and food resources dwindle. If some move south, this species will forage on buckthorn and planted European Mountain Ash berries and ornamental crabapples.
