Some colleagues and I are finalizing a very short paper on our detection of apparent nocturnal migration in Pine Siskins in Oct 2008. One of the reviewers suggested we ask other researchers if they have any unpublished examples of Pine Siskin flight calls recorded at night which we could mention on the paper.
Anyone have any experience with recording or hearing Pine Siskins at night?
