Martin Colony History: Started trying in 2012 and still trying

Just thought I'd share an observation. Most weekdays I eat my lunch in Ewing Park in Des Moines, Iowa. As I was doing so today, I just happened to look up at the right moment, and right at high noon and to my delight, I was treated to a group of around a dozen PM's swooping and soaring their way in general southern direction. Almost like they were saying, so long for now, and see you next spring.

2012 late start
2013 nothing yet, lots a lookers
2014 Bust again

Perfect timing, yep they will be back. A few short months from now too. I wish them all a safe uneventful stay in the Amazon and return flight home.
Thanks for sharing

Wow - how lucky was that for you to see them!! 6 or 7 months and we'll be watching the skies for their return. Thanks for the fun story.

Martin Colony History: In 2020, 60 pair with 285 fledged youngsters. 83 total cavities available, 58 Troyer Horizontal gourds and 4 modified deep trio metal house units, 1 fallout shelter, owl cages around all units.

This is why I wait a long time before taking down my gourds for the winter. Already looking forward to their return around first week of April at my location.
Mite control, heat venting, predator protection and additional feeding during bad weather add up to success.
