The Purple Finch (Haemorhous purpureus) is a medium-sized songbird species belonging to the family Fringillidae, native to North America. Males are particularly notable during the breeding season due to their vibrant purple-red plumage and melodious songs, whereas females exhibit a more subdued, brownish, and streaked appearance. This species breeds in coniferous and mixed forests but may expand its range into rural and urban areas during winter. Being omnivorous, the purple finch holds ecological significance due to its seasonal migration behaviors and its role in seed dispersal within ecosystems.

Morphological Characteristics
Haemorhous purpureus displays sexual dimorphism, which is clearly evident in its morphological features. Males exhibit a raspberry-colored reddish-purple plumage concentrated on the head, chest, and back, with a pale white belly. Females and juveniles have dark brown-streaked backs and a paler appearance resembling that of a sparrow.
This species measures approximately 15 cm in length, has a wingspan of 22–26 cm, and weighs around 20–25 grams on average. The beak is short, conical, and strong—well-adapted for seed-crushing. The tail is relatively short and slightly notched, and the wings are of medium length. These characteristics make H. purpureus easily distinguishable from similar species.
Vocalization
Haemorhous purpureus is known for its melodious and fluid song. The vocalizations are generally complex and delivered in sequences that last a few seconds. Males sing especially during the breeding season to mark territory and attract mates. This acoustic structure serves as a key distinguishing trait for species identification.
Distribution and Habitat
Haemorhous purpureus is endemic to North America. It breeds in the summer months across boreal forests ranging from southern Canada to Alaska. During winter, it migrates as far south as southeastern Canada, the eastern and western United States, and even northern Mexico. Its migration is partial and seasonal; some populations may remain year-round in certain areas.
This species prefers coniferous and mixed deciduous forests, particularly during the breeding season. It is often found in dense pine forests or wooded areas near swamps. In winter, it is observed in a broader range of habitats, adapting to rural areas, wooded parks, and gardens in semi-urban environments.

Migration Patterns
Purple finches migrate southward in the fall and return north in the spring. Migration behaviors can vary based on the age of the individuals and local environmental conditions. Populations at higher elevations tend to show more pronounced migratory behavior, while those in lowland regions may be more sedentary. During migration, individuals often join mixed flocks of other songbirds.
Feeding
The purple finch is omnivorous. Its primary food sources include plant seeds, fruits, flower buds, and insects. In winter, the diet is mostly seed-based, whereas in summer, insect consumption increases to meet protein needs. It particularly favors resources such as sunflower seeds, pine seeds, and blackberries. Foraging behavior typically occurs individually or in pairs.
Reproduction
Purple finches exhibit a monogamous breeding system and form stable pairs during each breeding season. Breeding generally takes place from April to July, depending on geographic location. The female constructs the nest, usually in the upper branches of coniferous trees; the nest is built from grasses, twigs, and bark on the outside and lined with feathers and soft plant materials on the inside.
A single clutch typically contains 3 to 5 eggs. The eggs are light blue with dark speckles. The incubation period lasts 12–14 days and is carried out solely by the female. During this time, the male supports the female by feeding her. The chicks fledge about 14–16 days after hatching, with both parents actively involved in feeding them during this period.
Conservation Status
According to the IUCN Red List, Haemorhous purpureus is classified as “Least Concern” due to its wide distribution and large population size. Although a declining trend has been observed in some areas, the rate of decline is not considered sufficient to meet the threshold for a threatened category.
