WINTER FINCH FORECAST 2017 - 2018

by Ron Pittaway

GENERAL FORECAST: Cone crops in the Northeast are bumper in 2017. It is the best cone crop in a decade or more. This will be a banner winter to see boreal finches in central and northeastern Ontario, Quebec, Atlantic Canada, northern New York, and northern New England States. White-winged and Red Crossbills and Pine Siskins have moved east to areas of abundant seed crops. The Big Question is: will finches concentrate in areas of highest cone abundance (more likely) or be spread out across the Northeast? This is not an irruption year south of traditional wintering areas in the Northeast. Cone crops are generally low west of a line from Lake Superior to James Bay extending west across the Prairie Provinces, British Columbia and Alaska. See individual finch forecasts below for further details. 

 
 
 
 

PINE GROSBEAK: Most should stay in the north because the mountain-ash berry crop is good to excellent across the boreal forest from Alaska to Newfoundland. Some should get south to Algonquin Park. At feeders they prefer black oil sunflower seeds.

PURPLE FINCH: Most Purple Finches east of Lake Superior should stay north this winter because of heavy seed crops on eastern conifers and mountain-ashes. They prefer black oil sunflower seeds at feeders.

RED CROSSBILL: There will be a good showing of Red Crossbills in Ontario and the Northeast this winter. Red Crossbills comprise about 10 "call types" in North America. Matt Young of The Cornell Lab of Ornithology reports that Eastern Type 10 is currently the most common type from the Great Lakes through Ontario into the Maritime Provinces and Northeastern United States. This year Matt also reports that Type 2, Type 3 and Type 4 and a few Type 5s from the west are moving east, the latter is a vagrant east of the Rockies. This movement started in late June/early July, presumably linked to poor or failed crops on several conifers in the western U.S. and Canada. Most types are impossible to identify without analyzing recordings of their flight calls. Recordings can be made with an iPhone and identified to call type by audio spectrographic analysis. Matt Young (may6 at cornell.edu) will identify types for you if you email him your recordings or upload them to an eBird checklist. This helps his research. He is particularly interested in recordings from Maine, Vermont, Michigan, Ontario and the Maritime Provinces. Red Crossbills probably will be breeding this winter into next spring. Expect to hear them singing and to see streaked juveniles.

WHITE-WINGED CROSSBILL: This crossbill flooded into the Northeast over the summer, drawn here by the bumper cone crops. Winter trips to hotspots such as Algonquin Park, Laurentians and Adirondacks are guaranteed to see this crossbill. They probably will be breeding this fall and winter. Watch and listen for their loud trilling songs given from tree tops and during circular slow-flapping display flights. Expect to see streaked juveniles in the flocks.

COMMON REDPOLL: Redpolls should move south because White Birch and alder seed crops are below average in northern Ontario. However, as redpolls move south they likely will be slowed or stopped by abundant conifer seed crops and better birch crops. If they get into southern Ontario south of latitude 45, good seed crops on birches and European Black Alder, and an abundance of weedy fields this year will attract them. When redpolls discover your nyger seed feeders, feeding frenzies result. Feeders are best for studying fidgety redpolls. Watch for the larger and darker “Greater” Common Redpoll (subspecies rostrata) from Baffin Island (Nunavut) and Greenland. 

HOARY REDPOLL: Watch for Hoaries in flocks of Common Redpolls. The “Southern” Hoary Redpoll (nominate subspecies exilipes) breeds south to northern Ontario and is the subspecies usually seen in southern Canada and northern USA. Watch for “Hornemann’s” Hoary Redpoll (nominate hornemanni) from northern Nunavut and Greenland. It is the largest and palest of the redpolls. Hornemann’s was formerly considered a great rarity south of the tundra, but recently it has been documented in the south more frequently with better photos. See link #2 for photos and identification of Common and Hoary Redpoll, and their subspecies.

PINE SISKIN: Siskins will be frequent and locally common this winter in the Northeast drawn here by abundant cone crops, particularly on White Spruce. Feisty siskins prefer nyger seeds in silo feeders. See link #3 which discusses siskin irruptions related to climate variability.

EVENING GROSBEAK: Most should stay in the north this winter because of abundant conifer seed crops and increasing outbreaks of spruce budworm. The most reliable spot to see this spectacular grosbeak is the feeders at the Visitor Centre in Algonquin Park. In 2016 the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) assigned the “Evening Grosbeak as a species of Special Concern due to strong population declines occurring mainly in central and eastern Canada.”

THREE IRRUPTIVE PASSERINES: Movements of these three passerines are often linked to movements of boreal finches.

BLUE JAY: Expect a much smaller than usual flight of jays from mid-September to mid-October along the north shorelines of Lake Ontario and Lake Erie. The acorn, beechnut, hazelnut and berry crops are generally good in Ontario.

RED-BREASTED NUTHATCH:  This nuthatch is now in areas with high cone abundance. Its presence indicates that White-winged and Red Crossbills, Pine Siskins and Purple Finches will be in the same areas.

BOHEMIAN WAXWING: Only a small flight south is expected because native Mountain-ashes have good to excellent berry crops across the boreal forest from Alaska to Newfoundland. In recent times Bohemians have been coming south more frequently probably due to now reliable annual crops of introduced Buckthorn berries. When they come south, Bohemians relish European Mountain?ash berries and small ornamental crabapples. It was historically called “Bohemian Chatterer” because flocks make a continuous “buzzy ringing twittering”.

WHERE TO SEE FINCHES: Ontario’s Algonquin Provincial Park is an exciting winter experience. It is about a 3.5 hour drive north of Toronto and west of Ottawa. Cone crops are excellent in the park so both crossbills, siskins and probably Purple Finches should be common. The bird feeders at the Visitor Centre (km 43) should attract a few Common Redpolls (watch for Hoaries), Evening and Pine Grosbeaks. The Visitor Centre and restaurant are open weekends in winter. On weekdays, it is open, but with limited services (no restaurant, but snacks and drinks are available). To view feeders on weekdays phone 613-637-2828. The bookstore has a fine selection of natural history books. Be sure to get Birds of Algonquin Park (2012) by former park naturalist Ron Tozer. It is one of the finest regional bird books. The nearby Spruce Bog Trail at km 42.5 and Opeongo Road at km 44.5 are the best spots for finches and boreal species such as Canada Jay, Boreal Chickadee, Spruce Grouse and Black-backed Woodpecker. Similarly, the Laurentian Mountains in Quebec and Adirondack Mountains in New York State will be great places to see finches and boreal birds this winter.

HISTORICAL NOTE: Our fascination with nomadic Winter Finches is a long-standing love affair. Here is an edited note titled WINTER VISITORS by A.M. Ross (1873) in The Canadian Ornithologist Vol 1, No 1, Toronto, Ontario. Current names are in brackets. "The past winter was remarkable in the unusual variety of rare northern birds which visited this section of Canada. During the month of January 1873, which was remarkable for the extreme cold and stormy weather, we observed small ?ocks of Red Crossbills, White-winged Crossbills, Bohemian Chatterers (Bohemian Waxwing), Pine Grosbeaks, Pine Finches (Pine Siskin), Lapland Longspur. Our regular winter visitors also appeared in greater numbers than usual with large ?ocks of Snow Buntings, Lesser Redpolls (Common Redpoll), Snowbirds (Dark-eyed Junco) and Shore Larks (Horned Lark). The appearance of so many rare northern birds in this section was doubtless owing to the extreme cold weather in northern Canada during last winter." This last sentence is a persisting myth still often repeated to explain the southern occurrences of northern birds in winter.
