Mating season is here!
The eastern population of House Finches is descended from cage birds that were released near New York City in the 1940s. They tend to breed in close association with people. (It’s in their genes!) At birdfeeders they’re putting on a show!
House Finches choose a wide variety of nesting sites, and will nest in many man-made objects such as window ledges or crevices in buildings. They may also even nest in wooden birdhouses. House Finches like birdhouses mounted just out of reach on a post. City backyards are good locations for these.
Often they will build a nest in a hanging plant.
You may lure a couple close to a window so as to watch their family life. The first requirement for this birdhouse is a solid base with some overhanging material. 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 lays 2 to 6 bluish, finely speckled eggs and Incubates them alone for 12 to 14 days. The male defends his mate (rather than a nesting territory as other birds do) and feeds her on the nest. He does this by regurgitating seed into the females mouth.
Then they hatch, and you have 12 to 15 days to observe the parents feeding the young right in the nest. After they fledge they may be fed by the male for about two more weeks, while the female starts a second clutch.
House Finches are monogamous, and will probably raise at least 3 broods in a season.
