Finches are a diverse and common family of birds that can be found in gardens, backyards, and forests across North America. Among the most frequently encountered finches are the Purple Finch and the House Finch. While both species belong to the same family (Fringillidae) and share many similarities in appearance and behavior, they also have distinct differences. These differences can make it challenging to identify one from the other, especially since their plumage colors can sometimes overlap. In this article, we will explore the key differences and similarities between the Purple Finch and the House Finch, and offer tips on how to distinguish between them.

What Are Finches?
Finches are small to medium-sized passerine birds that are known for their stout, conical bills designed for cracking seeds. They are part of the Fringillidae family, which includes around 200 species worldwide. Most finches are seed-eaters, though some may also eat fruit, nectar, or insects. They are often found in a wide variety of habitats, ranging from forests to urban areas.
The Purple Finch (Haemorhous purpureus) and the House Finch (Haemorhous mexicanus) are two species within this family that are commonly seen in North America, particularly in suburban and rural areas.
Physical Differences: Purple Finch vs House Finch
While both the Purple Finch and the House Finch are small, colorful birds, there are a number of features that make it easier to differentiate them. The most noticeable differences are in their plumage, size, and shape.
1. Plumage and Coloration
The most obvious difference between the two species lies in their coloration and the intensity of their red plumage.
- Purple Finch: Male Purple Finches have a striking, raspberry-red color that covers most of their head, throat, and chest. However, this red is not as vibrant or uniform as that of the House Finch. The wings and back of the Purple Finch are often brown with darker streaks. Females and young males of the Purple Finch are typically more brown and streaked, lacking the vibrant red hues of the males.
- House Finch: Male House Finches are also known for their bright red coloration, but their red is typically more brighter and uniform than the Purple Finch. Male House Finches may display a deeper red across their head, chest, and back, and some may even have an orange or yellowish tint depending on their diet and environment. Female House Finches are similarly streaked but tend to have a more muted, brownish or grayish color with subtle streaks across their belly and chest.
2. Size and Shape
Though both birds are small, there are differences in size and overall shape:
- Purple Finch: The Purple Finch is slightly larger than the House Finch, measuring about 5.5 to 6 inches in length and weighing around 0.9 to 1 ounce. The Purple Finch also has a sturdier, more robust appearance, with a thicker, more triangular bill.
- House Finch: The House Finch is a bit smaller and lighter, typically measuring about 5.1 to 5.5 inches in length and weighing approximately 0.5 to 0.7 ounces. Its bill is smaller and less conical than that of the Purple Finch.
3. Behavior and Vocalizations
Both species are highly adaptable to human environments, but they also exhibit some behavioral differences.
- Purple Finch: The Purple Finch is generally more reclusive and tends to avoid human contact, often found in woodland areas and forest edges. They are more arboreal, spending much of their time in trees and shrubs. They are also known for their melodic songs, which are typically rich, sweet, and warbled.
- House Finch: In contrast, the House Finch is extremely urbanized and thrives in cities, towns, and suburban neighborhoods. It is more often seen at bird feeders, on telephone wires, or perched on building ledges. House Finches have a shorter, choppy song that can vary, but they are generally less melodious than the Purple Finch.
Habitat and Range: Where to Find Them
While both finches are native to North America, their habitats and geographic ranges do overlap to some extent.
- Purple Finch: The Purple Finch is primarily found in the northern parts of North America, particularly in Canada and the northern United States. During the winter, Purple Finches may migrate southward, but they tend to prefer wooded areas such as forests, coniferous woods, and forest edges.
- House Finch: The House Finch has a much broader range and is commonly found throughout much of the United States, as well as parts of Mexico and Canada. It is an extremely adaptable species that thrives in urban environments, suburban neighborhoods, and agricultural areas. The House Finch is a common sight at bird feeders and can also be found in deserts, parks, and rural areas.
Diet and Feeding Habits
Both finches are primarily seed-eaters, but their feeding habits can vary slightly due to their differing habitats and behaviors.
- Purple Finch: The Purple Finch feeds on a wide variety of seeds, including sunflower seeds, pine seeds, and the seeds of various weeds. It also feeds on fruit and may occasionally consume nectar. Because it tends to live in forests, it often forages on the ground and in the trees for seeds and berries.
- House Finch: The House Finch is also a seed eater, but it has adapted very well to urban environments. It is frequently seen feeding on birdseed at feeders, as well as berries, fruit, and vegetables. House Finches have also been known to visit gardens and agricultural fields, where they feed on a variety of cultivated plants.
Breeding and Nesting
Both species build their nests in similar locations, typically in trees, shrubs, and even on man-made structures. However, there are differences in their nesting habits and preferences:
- Purple Finch: Purple Finches typically build their nests in trees such as conifers or hardwoods, about 10-20 feet above the ground. They often use twigs, grass, and feathers to construct a cup-shaped nest. Purple Finches are known to lay 3-5 eggs, which are typically blueish or grayish with speckles.
- House Finch: House Finches are much more likely to build their nests in human-made structures, such as eaves, gutters, and hanging plants. They have also been known to build nests in cacti in desert areas. Their nests are built with similar materials, including twigs, leaves, feathers, and paper. House Finches typically lay 2-6 eggs, which are light brown or white with spots.

Frequently Asked Questions (FAQs)
1. Can a Purple Finch and a House Finch mate?
While the Purple Finch and House Finch belong to the same genus (Haemorhous), they are distinct species, and hybridization between them is very rare. If hybrids do occur, they tend to have intermediate characteristics.
2. How can I attract Purple Finches to my backyard?
To attract Purple Finches to your backyard, consider providing a variety of seeds such as sunflower seeds, and set up birdbaths or bird feeders. Additionally, planting shrubs and native trees can help create an inviting habitat.
3. Are Purple Finches more common than House Finches?
No, House Finches are much more common than Purple Finches. House Finches have adapted well to urban environments and are widely distributed throughout North America, whereas Purple Finches tend to inhabit more forested, less urbanized areas.
4. Why are House Finches so common in urban areas?
House Finches are highly adaptable to human environments, thriving in urban and suburban areas due to their ability to nest in buildings and eat a wide range of foods. Their ability to live in close proximity to humans has contributed to their widespread population.
Conclusion
Though the Purple Finch and the House Finch may appear similar at first glance, they exhibit distinct differences in size, coloration, behavior, and habitat
