The common redpoll is a common sight at winter bird feeders. Either we failed to notice this little bird in earlier years (up to 2008), or it is favouring the area more in recent winters. It is a winter finch (for those of us in southern Ontario). More than 95% of the sightings summarized here were made in the winters of early 2009, 2011, 2013 and 2015, suggesting an increasing frequency and intensity of winter irruptions from the north. Such events may bring other birds, such as the rarer crossbills. The breeding range in Ontario extends from Moosonee northwest to the Manitoba border (Cadman et al., 1987, pp.561-562). It is commonly found north of the boreal forest, and has a circumpolar distribution in the northern hemisphere. The addition of new data (Cadman et al., 2007, pp.618-619) confirms that the bird nests along the northern James Bay and Hudson Bay coasts, generally between late May and mid-June.
The common redpoll is an irregular visitor to Presqu'ile provincial park, roughly 40 km to the south, from late October to early April (LaForest, 1993, pp.385-386). It is not present every year, but is seen perhaps three years out of five. The highest numbers are generally seen in February (the Trent Hills data are consistent with this). Indeed, the latest substantial flock, of 35-40 common redpolls, was seen at feeders in Campbellford on 06 February 2015, the first sighting of the species that year, after which smaller numbers (often just 1-3 birds) were seen in the following few weeks.
The story is much the same in Peterborough county, to the northwest.
The bird is an irregular winter visitor and migrant
(Sadler, 1983, p.163).
Extreme dates are 24 October to 30 April, again consistent with the
more-recent sightings in Seymour Townshuip.
