Martin Colony History: 24 Super and Excluder Gourds on two gourd racks, all SREH. Full occupancy. My philosophy is to maximize fledge % with existing cavities rather than adding gourds to grow colony, thus providing opportunities for new colony expansion. Fledge over 100 nestlings yearly from 24 gourds. Band nestlings in cooperation with state university. 2019 Adendum: Reduced colony size to 12 gourds to focus on more intensive management regimen.

Did quick nest checks of the first 5 completed clutches and found one nest hatching. Still in the process as I write this.Others will be right behind. Hatch day in 2012 was 6/6, 6/12 in 2013, 6/16 in 2014 and 6/6 last year. The real fun begins today.

Success to all this year.

Great news, Ed. As previously reported, we had 2 pair/12 eggs last year. 6 pair/35 eggs this season, with the earliest two pair should have their eggs hatching on the 12th.

Keep us posted on how things go!

You have a manageable number which will allow you to keep close tabs on your martins. Watch for vermin. I have never had mites but blow fly larvae can be an issue here in Wisconsin. I replace nests at 10 and 20 days and use Sevin sparingly. I have found the blow fly larvae to be the most damaging in the first 10 days. If you used Sevin under the nests when you constructed them, you should be ok.

Watch closely and your colony will expand again next year. Grow into it.
