It's my understanding, that one female cowbird can during the course of one summer lay upwards of 40 eggs, and in theory compromise an equal number of nests. While I understand the life history of cowbirds and the extent to which humans thru their activities stack species against each other, I also understand that the laissez-faire attitude of not doing anything about them, will ultimately lead to the demise of untold bird species?
Only six pair of cowbirds, only 240 compromised nests. Mark Palas ---- Join or Leave mou-net: http://lists.umn.edu/cgi-bin/wa?SUBED1=mou-net Archives: http://lists.umn.edu/archives/mou-net.html
