As both a dog person and a bird person, I would please ask that you never allow your dog to chase any birds in any public area, or open area.
I belong to a bird forum and there are always complaints about people allowing their dogs to chase birds. You may not recognise them, but there are a lot of endangered and rare birds, including waders and ducks out there, and everyone, dogs and birds needs their space.
I am sure that responsible dog owners will respect the environment around them, because if they don't they could end up being banned from some areas.
This is just a message, don't shoot the messanger.
