No, Caryn, purple finches are not the same as house finches. :) I like purple finches, but place house finches the same category as mice. We used to call them English sparrows and didn't like them because they were so prolific and took over the nest sites of other more desirable birds such as blue birds or purple martins. Cleaning out house finch nests from the martin house was a spring chore that I didn't particularly enjoy but did because they started nesting before the martins arrived and occupied every available space, which made them unavailable for the martins. They along with starlings were introduced species that adapted too well. Check this site for more information:
