Eggs have been collected from March 18 to August 4 (Oberholser 1974). Of 37 instances of Confirmed breeding found by TBBA field workers most dates were from May, June, and July within the overall period of April 1 to July 28. House Finches in the western United States may raise several broods per year (Harrison 1979). Data are not available on the presence in winter of migrants from other states. Areas of House Finch population are also found in southern Idaho, Nevada, Utah, Colorado and western Nebraska.
Where Do House Finches Nest?
The House Finch is closely related to the Cassin's Finch and the Purple Finch, and in fact, there are places in Washington where all three species can be found. All three species are streaked, and the males of all three have red plumage. The House Finch, the most common and widespread of the three, typically has a red head, breast, and rump, but does not have red coloring on its brown back or wings. Female House Finches have blurrier streaks and grayer undersides than the other two species. The breast streaks do not converge in a central spot as on many sparrows.
Eggs
Of the at least 13 described subspecies, 4 occur in North America north of Mexico. Subspecies frontalis, the most widespread throughout the United States, sports a generally more orange-red to yellow breast and has less distinct streaking on the belly. Both the clementis from the Channel Islands in California and the potosinus from central Texas are brighter red, with bolder streaking on a whiter belly. Purple Finches aren’t purple, and House Finches don’t stick to houses. But that’s only the start of the confusion around these two doppelgangers.
Females/immatures and males
Note very thick bill with curved rather than straight-edged profile. Red on head is largely on the eyebrow and throat, with brownish cheeks. Their vibrant colors and cheerful songs can bring joy and a sense of tranquility. Long-term, think about the vegetation around your property.
The female builds most of the nest, which is an open cup of grass, weeds, twigs, leaves, and rootlets, lined with feathers and other fine material. The female incubates 4 to 5 eggs for 13 to 14 days while the male brings her food. The female broods the young for the first few days after they hatch, and the male continues to bring food. The female then joins the male in bringing food to the young. The young leave the nest after 12 to 15 days and may be fed by the male for about two more weeks, while the female starts a second clutch. Adults have a long, square-tipped brown tail and are a brown or dull-brown color across the back with some shading into deep gray on the wing feathers.

The female House Finch is a little more tricky to identify, as they look more like a house sparrow with a few key differences. They live in large enclosures with lots of space to fly, and aviaries in particular work well for their care. Their enclosures have plenty of perches for them to land on, and a variety of low shrubs to forage and hide in. Like most finches, they thrive on a seed-based diet with plenty of supplemental fruits and berries.

During summer, they eat fruits and seeds from native plants, along with bugs. Both birds are drawn to feeders, and Trina suggests filling them with unhulled black oil sunflower seeds. Baby house finches generally leave the nest days after hatching. However, the male takes over most of this responsibility in the days before the chicks fledge. Each clutch of eggs can have between 2-7 eggs, with 4-5 being the average.
House Finches nest in a variety of deciduous and coniferous trees as well as on cactus and rock ledges. They also nest in or on buildings, using sites like vents, ledges, street lamps, ivy, and hanging planters. Occasionally House Finches use the abandoned nests of other birds. Females/immature males are brown overall with heavily streaked underparts.

The oldest male and female were 12 years and 10 years, respectively. Not every sighting of every bird has a particular meaning. These birds are pretty common and do not hold any symbolic meaning in most cultures.
The incubation period lasts about days, and the nestling period, where baby house finches stay in the nest, lasts about days. House Finches are often found in suburban areas hanging out around bird feeders and making nests in unusual places! The human modification of natural habitats, particularly the increase of seed feeders throughout the east, greatly benefits the house finch populations. Only natural island populations appear to be threatened.
House Finches in west Texas breed in a variety of habitats from 120 to 2100 m (400 to 7000 ft). The birds prefer drier areas with less than 90 cm (35 in) of rain annually (Oberholser 1974). House Finches may reuse nests for a second brood in the same or another year. The cup is usually well constructed of plant fiber (grasses, forbs, rootlets) lined with finer material. The clutch size is 3-6, usually 5 eggs, which are incubated by the female for days (Oberholser 1974, Harrison 1979). Young birds leave the nest days after hatching (Kaufman 1996).
Once hatched, baby House Finch broods typically leave their nest in days. While their diet consists primarily of seeds, fruit, and nuts, on rare occasions, they will also eat insects in the summertime. They travel in flocks and take their migration day by day. They will travel a great distance during the day and stop to feed and rest during the nighttime. They often construct their nests in trees but sometimes build nests on the sides of buildings, street lamps, or even abandoned nests. These North American birds prefer to nest in dense areas with plenty of shade and places to hide, so there aren’t frequently found in the Rocky Mountains.
