Thank you all for the great tips. I'm trying several of them. I ordered an inside cavity sparrow trap from the PMCA Shop, placed bread and pieces of paper towels all around the outside of my repeating trap and on the bait trays, and I'm trying EGunterTX's suggestion of using a glue board inside the entrance with tape over the outside inch or so on each side of the crescent. I'm also keeping a close watchful eye on the PM barn. Wouldn't you know these sparrows are too smart for me and they are staying away from the barn since I put the glue boards inside the two compartments they are attached to.
I have good news to report about my bluebirds that The HOSP stole their eggs. They came back today!
The female laid her first egg on this past Monday, her second on Tuesday, and the HOPS stole the eggs on Wednesday. I'm hoping that she is still in the egg laying mood and she will consider trying to lay more eggs in my BB box. I put the sparrow spooker up as soon as I saw the BBs return. They don't seem bothered by it and the HOSP haven't been around the BB box either. It may be because I have had painters painting our house all day they went some where else while the painters worked. I have to keep an eye out for them tonight and this weekend while the painters are gone.
I'm just curious is there a bluebird forum or a site that I can post questions to that I can get answers about BBs from that is similar to this PM forum? I love that this site is available to us amateur bird hobbyists.
I gotta mention, it is funny, today when I went to my local Bird Nerd Store (what my kids call it) I picked up the PM Morning Vocalizations cd that has been the big talk today on the forum. At the time I never heard of it and was leary about buying it without knowing if it was any good. Then I get on the forum this afternoon and see that the exact same cd is being discussed on the forum. I can't wait to try it out. Hopefully it will convince some of the SY's, that will most likely be visiting my neighbor's established colony within the next coming weeks, into coming to my barn and gourds. I estimate that I live about 1,500 ariel feet from his colony. So Maybe I have a chance. I have seen a few fly by my set-up. One male was showing a strong interest in my two PM decoys this past weekend.
