Common Redpoll or Lesser Redpoll?
Here's how to tell the difference
Common Redpoll
Lesser Redpoll
Common Redpoll
Acanthis flammea
Also known as: Mealy Redpoll
General appearance
The common redpoll is of small size, similar to a sparrow, with a length of 5-5 1/2 inches (13-14 cm). It features a red forehead, a black chin, and maintains a darker overall appearance during the summer seasons. Its wings are pointed, and their tail shape is either notched or square-tipped.
Male vs female
Sexual dimorphism exists in common redpolls. The male redpoll is distinguished by a variable pink wash over its chest. The female, on the other hand, doesn't exhibit this coloring. Both sexes, however, exhibit the signature black chin and red forehead.
Juvenile
The juvenile common redpoll has similar features to the adults but may not have developed the identifiable red forehead or the male’s characteristic pink wash on the chest. The plumage patterns and color intensity may also differ, becoming more pronounced as they inch towards adulthood.
Size

Acanthis cabaret
General appearance
The lesser redpoll is a small, finch-like bird, noted for its slender shape. It exhibits a distinctive red poll (crown) on the head, black bib, pale, streaked tummy and brown back. The tail is black on top with white undertail coverts. Its wings bear dark brown feathers with two striking white wing bars.
Male vs female
Males and females are similar, but males are easily identified by their red breast and face, most evident in spring and summer. In contrast, females are duller, largely buff-colored with less extensive red markings. Both sexes have lighter, less vivid hues during autumn and winter.
Juvenile
Juvenile lesser redpolls are similar to adults apart from their lack of red coloration. They are mainly brown-grey with streaks and have a yellowish bill. The red cap and breast become apparent after the first moult.

Visual differences
Common Redpolls are slightly larger (5-5.5 inches) than Lesser Redpolls (4.5-5 inches). Common Redpolls have a red forehead, black chin, and males exhibit a pink chest wash, while Lesser Redpolls have a red crown, black bib, and males show a red breast and face. The Common is generally darker, especially in summer, and has a notched or square-tipped tail. Lesser Redpolls are slimmer, browner with more streaks, dark tails with white undertail coverts, and distinctive white wing bars. Both have yellowish beaks, with the Lesser having a more slender shape.
Key differences and behavior
Common Redpolls (Acanthis flammea) and Lesser Redpolls (Acanthis cabaret) exhibit distinct behaviors. Common Redpolls, primarily breeding in northern bushy regions, form small flocks and are monogamous; their cold weather adaptation includes snow tunneling. During breeding, females take courtship initiative and nest in dense shrubs. They primarily feed on seeds but include more insects in summer. Lesser Redpolls, adaptable and sociable, thrive in diverse temperate habitats, including urban areas. They flock for feeding, and both parents participate in chick rearing. Males attract mates through song and aerial displays, contrasting with the Common Redpoll’s simpler courtship. Their diet is primarily seeds, supplemented by insects during breeding, similar to the Common Redpoll.
