We have some birds (we think starlings) who have found a home in the arbor vitaes lining our backyard deck. Not an issue, until they started flying at my dog at every turn and he's now afraid to go out there alone. In addition, they have become quite brazen with us adults - flying close by us when we're out there with our 8 week old baby. It's becoming scary! We purchased a big plastic owl to see if that would ward them off, but no such luck. Not sure what to do since they have babies in the tree but I would appreciate any suggestions on how to force them to move! I normally wouldn't mind them being there but like I said they're becoming aggressive.
