Acanthis flammea
The Redpoll, specifically the Common Redpoll (Acanthis flammea), is a small, energetic, and highly acrobatic finch, celebrated for its adaptability to frigid northern climes and its distinctive irruptive migrations. Measuring approximately 11.5-14 cm (4.5-5.5 in) in length with a wingspan of 20-25 cm (8-10 in) and weighing 10-18 grams, this species is characterized by its streaky brown and white plumage, black chin patch, and a vibrant red forehead patch that gives it its name. Males boast a ...
Common Redpolls primarily inhabit open coniferous or mixed woodlands, birch and willow scrub, and tundra edges across arctic and subarctic regions, typically at low to moderate elevations.
Primarily granivorous, consuming vast quantities of small seeds, particularly from birch, alder, and spruce trees, supplemented with buds, catkins, and some invertebrates, especially during the breeding season.
Outside the breeding season, Redpolls are highly social, forming large, often boisterous flocks that can number in the hundreds, sometimes mixing with other finches like siskins. They are diurnal, spending their days actively foraging. Their foraging strategy is remarkably agile; they can often b...
The Common Redpoll exhibits a vast circumpolar breeding range across the arctic and subarctic regions of North America, Greenland, Iceland, northern Europe, and northern Asia, primarily utilizing boreal forests and tundra edges. Its wintering range is highly variable due to its irruptive nature, ...
Least Concern
- Redpolls possess a specialized esophageal diverticulum (a pouch in their throat) where they can temporarily store seeds, allowing them to gather food quickly and then digest it in a safer location. - They are incredibly cold-hardy, capable of surviving temperatures as low as -54°C (-65°F) thank...
