must be 'barn swallows' ?? They WILL keep coming back, year after year after year after.......kinda like salmon ??

I destroyed their nests..they came back

I closed the doors when I could, they came back

I SOLD the shop, not MY problem anymore....hehehehehe

you might try the BIRD-X units. They worked so well at Disney you could eat your food without being swarmed upon by any birds...

Not Barn Swallows. I like to keep those birds around. They eat a lot of bugs in the summertime. They stay in my old barn in the basement. The Sparrows are here all season and have taken residence in my lean-to. 

I've bought two of these.  They work!  Be prepared ahead of time with a dispatching solution (I wring their necks).  I've caught hundreds, over the past 15 years or so.  English sparrows are not "protected".  I hate 'em!

 My problem is with the little sparrows getting into the chicken coop and eating the chickie food. Most times there will be a madhouse of 20 or so sparrows inside the coop eating up what I just put in there for the chickies,,,within just a few minutes all the groceries will be GONE and the chickies won't have any groceries for rest of the day or for "snacks". Them little sobs will fly and land on the chicken wire openings and work themselves THRU the openings, eat till full and then right back  thru the openings!!! I'm thinkin bout putting some other wire with smaller openings,,,,?? I think them little sobs is calling thier friends about them good gorceries ole Joe has got served up,,,,,,,

 Yeah Dave,,,,I wouldn't mind but them little sobs will eat till the eat up all the chickie groceries,,,then have to feed again mid day,,,,,PSHAAAAaaa!! (Thats a new one for ole Shameless)

  My youngest Son and grandson built the 10' X 10' X 8' coop and did pretty good job and was not gonna put a top til I told him them chickies Can and Will fly over the top and then them two big bruisers will have them for supper,,,!! or maybe the foxes will, so he framed the top and now has chickie wire all over,,,just has the openings too big to keep them food Robbers OUT!! I have the Top covered with a tarp for summer heat control and am thinking bout getting some other kind of wire panels for the sides,,,,dang sparrows!!!!!

I get my entertainment watching the cats trying to catch hummingbirds at the feeders somebody thinks she needs to keep filling. One O'l momma cat is better than 50% some others no so much.

When I was a kid every barn had few pigeons living in them.  I have no idea if they us to taste better,   some talked about eating them. But never knew anyone that did. The last 30 years finally no pigeons left that I know of.

If possible shot a few birds besides any other method and you will have less birds. In Joes case kind of in town, maybe start the grandson on being the great hunter with a BB gun. The sitting quit and waiting and then being reasonable and not hitting some the "treasures" Joe has sitting around. Or the chickies.
