I am thinking most, if not all, of the PMs from Canada and the north are already down past here (southern WI) so there's not need to keep playing it now? Advice, please and thank you.

Martin Colony History: have not had martins for last 20 yrs. trying to re establish a colony
2018 1 asy pair fledged 2

I would say you can put it away Billie, my son did see a small flock of martins fly over 2 days ago, but they were heading south, our birds have not been around for 2 weeks now. I think fall migration is well under way, good luck next year!!

Been five days since my last martins completely moved on here in central Iowa.
Mite control, heat venting, predator protection and additional feeding during bad weather add up to success.

I live in northern SD and continue to play my chatter CD until mid-Sept. each year I had 7 martins visit my site for a few hours last year as late as Sept. 7th. In years' past they've visited my housing through about the 15th of Sept. I had a HY martin visit my site last Friday as it passed through. I was in Bismarck, ND most of the weekend and still saw a fair number of martins in that area near a local roost. I left my CD play 24-7 for the entire weekend while I was gone, so perhaps could have had more visitors to my housing over the weekend? I believe the next big cold front and northerly winds will likely push these northern stragglers southward. If you are trying to start a new colony or add members to an existing colony in the northern tier of states, it won't hurt any to keep your housing up and continue playing the martin CD for another week or two.

All right, thanks! That's good to know. It won't hurt to keep playing it then - if there are a few still coming south from Canada or the north.

I second the motion. Those trying for a new colony beginning can keep the martin music flowing as the late migrators may move through the area.

I had one more HY martin visit my site on the 4th and three more stopped by today. Initially they swoop by the speakers and decoys for a few minutes, but then lose interest in those distractions and then move on to investigating the housing. They typically stay for a few hours, then continue their journey southward. Hopefully they mark this spot on their GPS for their return trip north next spring!
