Softly softly..catchee pigeon

I'd like you to meet Columbine the Pigeon, the latest bird to become trapped under the 'anti-pigeon' netting at work. Her boyfriend keeps landing on the outside of the netting and bouncing up and down. My only fear is that he will become entangled in it - if that happens, I can't help him, other than get someone in to shoot him?

I've put a little food and water out for her tonight, the trap is in place but not set (she'd probably freeze to death if she went in it tonight).

I'll set and bait the trap tomorrow while I'm at work. Any predictions on how long it will me take to catch her?
