House Finch

Erika and I found House Finches among the House Sparrows in a bramble-filled hedge row near Olympia on 22 January 2021. House Finches were originally were found in southwestern deserts. Thanks to releases of birds in New York in 1939 and subsequent spread across eastern North America, House Finches are among the most common birds across most of North America. At same time as the birds were spreading from New York, western birds spread north and became much more common in areas where they were previously found, if at all, in small, isolated populations. The species now inhabits nearly all types of habitats. Wahl et al. (2005) suggest that the species’ expansion in Washington (and elsewhere) is partially due to a great increase in bird-feeders.
