Purple Martin Colony Loss: Getting Your Martins Back

Wednesday, July 11th, 2012

Here is a question I received concerning what to do when a colony is lost due to predation.

Q:

Dear PurpleMartins-R-Us:
My 92-year old grandfather has two purple martin houses (a 24-compartment house and a 12-compartment house). Unfortunately, after about 10 years of successfully colonizing, snakes climbed the poles about five years ago and that was, of course, the end of the purple martins. He misses them dearly and is highly motivated to resume his landlord duties should the martins come home.
My question is, how do we bring the martins back? He continues to clean the houses and raise them in time for their migrations, but to no avail. Do we need to replace the houses? Do we need to move the houses?
We appreciate any advice you can offer and thank you for your time!

A:

Basically he has to start from scratch. Use tools like dawnsong CD’s to attract them in to the site and decoys, prevent any further predation from snakes and he should be able to attract new martins from his surrounding area. Unfortunately, The martins that lived in his houses, that lost babies due to the snakes, will never return. Moving or changing the houses should not be necessary.

This question highlights the need to vigilance when it comes to protecting your colony from predation. Predator Guards, Snake netting and nest checks are tools that can keep your martin colony healthy and thriving.
