I would go ahead and set the trap if they have an active nest. I would set it immediately after work and keep it going until both are caught. I would even leave it set during work, if I had too. I forgot I had set a trap once and went to work all day. I noticed it was sprung when I got home. So I put the mesh bag over the box and slowly opened to door, I saw a small bird laying on its back with its feet in the air. I thought it was dead and opened the door all the way to determine the species. It was a male HOSP and he quickly awoke and tried to escape. I barely caught him. I dont think temperatures are that hot yet so I wouldn't worry about one dieing in the box. I don't think a native would go in an active nest anyhow. I know some in the purple martin community believe in "sparrow revenge" or "sparrow rage", which occurs when a HOSP nest are often disturbed. The HOSP becomes frustrated and destroys the nests of other cavity nesters. So they recommend trapping or shooting rather than disturbing the nest. They are also confident that natives wont enter a HOSP nest, some routinely use glue traps in the nests. You could still remove a native if you had too.

Sorry if I'm repeating...haven't read all the comments. Michael Payne and Designing for the Sexes rocked!!! That was real talent and class, and you always learned something about design. I also really enjoyed Decorator's Challenge and Landscapers Challenge because these were actual talented designers who gave 3 unique perspectives on one project. Now everything on HGTV looks exactly the same ( i.e. gray walls, hardwood floors, too many randomly patterned throw pillows, contemporary furniture). Where's the variety? Bring back Chris Casson Madden (Interiors by Design) and Joann Liebler (Room by Room), Mission Organization, Donna and Shannon Freeman (Secets That Sell), Before and After, Dream House, Weekend Warriors (a personal favorite) Susie Coehlo (Surprise Gardener), Debbie Travis (The Painted House) and shows like Location, Location, Location that showed different aspects of people purchasing homes. I am rather annoyed by how House Hunters is always about a bickering couple who can't agree on style, but at 22 can always afford to buy their dream home. How about showing a variety of homebuyers again; older people, singles, working parents who can't afford to gut and renovate. I'd like to see people with more modest budgets take the homes they purchase and turn them into something wonderful. And for those who are not familiar with any of these shows or hosts, you really missed a treat. This was HGTV at its prime. Believe it or not, long before the last season or two of Divine Design, and long before that crap Candice Tells All, Candice Olsen actually used to design rooms without mirrored furniture, espresso wood, and ice blue and gray. Anyone remember the sherbert colored sunroom or the kitchen with the blue strie (sp?) cabinets? Those were the days... Not that the Property Brothers arent't good, and I do particularly like Hillary Farr's style (even if she can't budget worth a darn), but enough is enough. And don't get me started on Genevieve. She sucked on Trading Spaces! Now if the would just dig up the Designer Guys from the Discovery Channel, all would be well. Anyone who can design a woman's apartment around a man's suit and make it look fabulous is okay in my book. Done with my rant....i'll get back to work

Couldn't do the trap because my job has me gone for long time daily but I did shoot him with the BB gun, but to my surprise the blues are roosting on the house but I guess they needed to nest quickly so I have an old dead tree in my back yard and I saw them flying around it and to my surprise there is a hole so I got my flashlight and they built a nest in it and there are 3 eggs already.....I quess they just couldn't wait. I'm hope the second time around they will use the house since the sparrow is gone. But thank you for all your advise your right only way to get rid of the house sparrow is to kill it.

Yes, they do, Mama Pinky. I left some info for you for your neighbor with the baby possum.....what to feed it. Don't know if you saw it. They get crippled very easily if not fed a good diet. On that other thread where we talked about the raccoon in your yard. She is a lot tamer... every day. I wish she would think I was her Mama. Would make it easier for all concerned. It is hard to find enough time to spend with her. I have considered getting another one from my partner. I have even considered sending her there. I probably won't do that though, because I still think she has a better chance (life) here. I don't want to put her in a cage. Right now she is in a crate but I will be letting her out to stay with me in the house, whenever I can.
