Does any one know what to do about cowbirds? It seems that every nest of birds near my house has cowbirds in them. The poor birds are being chased by the cowbirds, and I keep finding eggs on the ground. I even saw a pair of pigeons taking care of cowbirds. I would rather have pigeons than cowbirds lol. anyway I was wondering if there was anything that could be down to discourage (sp?) the cowbirds from coming near my yard, without killing them. I'm wondering where all the neighborhood cats are, they keep killing all of the good birds but leave the cowbirds alone. Thank you. They are brown headed cowbirds if that helps.
