A cat may be useful here. They sure are usefull for much else. DT Dale Hooper wrote:

Relating this all back to amateur astronomy ...and speaking of birds... I am having a difficult time with starlings and my observatory. They keep p**ping all over everything and no matter what I do they can't seem to get it into their skulls that this is a bad place for a nest. I can't shoot them - I'm in city limits (although admittedly at this point - I would like to). Any ideas of how to keep them away? I've already tried a fake owl - which worked for a couple days. I've screened off a lot of things - which has helped. But, they keep trying to make nests along the rail - which I destroy on a daily basis - but they just keep coming back. HELP!!

Clear skies, Dale.
