The validity of the Crow Vending Machine has been put into question because of misinformation given to reporters. Josh Klein never worked with Binghamton University like he claimed but the newspaper didn't catch it. John Klein says it was a misunderstanding. Who knows what the truth is? I would like to see the experiment repeated a time or two to find out. Read more here.
We know many people do not share our appreciation for crows and jays. They can often been seen as pests or bullies, particulary when it comes to backyard bird feeders. If you want to keep the crows and Jays away from your bird feeders, protecting your little birdies, you can throw out whole pieces of bread (away from the feeders), cereal flakes or corn chips. These big pieces of food are edible for all birds but intimidate most of the smaller birds. The smaller birds prefer the seeds and smaller nuts. While the crows and jays can hardly resist the bigger food sources thrown towards them. This will ensure that all the birds are fed and safer. Another way to entice the bigger birds with the bread is to spread suet on it --- they will be unable to resist this open-faced energy sandwich. Be sure not to throw out moldy bread. This can harm the birds and we DO NOT advocate harming any birds---particularly our beloved corvids. We also do not recommend putting bread out while it is raining because birds don't like soggy bread anymore than we do. The big birds and small birds can peacefully coexist in your yard or porch, if you just take a few extra steps. =)
