I have 5 wooden feeders in my backyard plus i plastic feeder.I also have a suet cage and make pinecone peanut butter treats for them.I have noticed that the feeders that are mounted on wooden posts seem to get the most use,I am wondering if the birds prefer the base more solid.I currently have chikadees,grosbeaks,bluejays,and woodpeckers here.I am also seeing birds i havent had here before,they are black and quite large,with a cream coloured beak)(smaller than a raven but bigger than a jay)if anyone knows what they could be,please let me know.I am in northwestern Ontario.Thanks Cheryl
