Wild food preferences of Common Redpoll
The primary wild food of Common Redpolls is tree seeds. The winter finch survey is
showing that redpolls are most often found in areas of moderate to heavy seed crops.
The 1997-98 Perspective:
- The earliest indication that 1997-98 would be a winter finch irruption year came in
mid-September, with the report of Common Redpoll in northern Michigan.
- As early as mid-November, Common Redpolls had moved south into Iowa, Indiana,
Pennsylvania, and Delaware, suggesting the magnitude of this species’ irruption.
- During the month of December the number of reports of Common Redpoll decreased while the
number of Common Redpolls in each report increased. This may indicate an overall increase
in flock size as irrupting Common Redpolls flock.
| Listen to a recording of Common Redpolls from the Library of Natural
Sounds. The first example is that of their trill, then there are a series of flight calls
followed by an example of how they sound in a flock.
