Finch Songs

House Finch (Apr, PA).












House Finch "pre-copulation" song, often given in the close proximity of a female, includes waxwing-like whistles (Mar, PA).











In this case the male was solitary (Mar, NJ).



Purple Finches have two different songs. One is extended and often includes mimicry (July, ME).

The other is shorter and more stereotyped (July, ME)













Purple Finch "vireo song", interspersed with flight calls. This song version can be heard in fall or spring and sounds similar to a Red-eyed Vireo (Oct, PA).













American Goldfinches sing from early in the spring, even though they won't be breeding until July. The accompanying female often calls (Apr, NJ).

Hoary Redpoll song (singing in bush,June, AK). In this example, the song has 8 different repeated notes. The song of the Common Redpoll is apparently similar, and males use up to 16 different notes in their songs.

White-winged Crossbills trading trills, probably a simplified song (June, AK).
