Purple Martins depend
almost entirely on humans for housing. If you put out appropriate
accommodations they may just settle in at your place.
Their criteria for nesting
sites are usually near some water (or some other source of insects), and plenty
of safe, clean housing. The birds also need on open area (meadow?) around the
nest with a 40 ft. radius circle - no big trees.
In Texas, white is by
far the best color for a house. They’re
typically aluminum, and look like little apartments with round doors. The dimensions of the holes, and the
“apartment” itself, are crucial in deterring predators. For heaven’s sake, don’t
buy what’s alleged to be a Martin House without a proper pole – one that is
stable and raises/lowers the house without calling for ladders or cranes. An
appropriate pole is almost impossible to buy by itself.
If you’re thinking
about becoming a Martin landlord, remember that there’s some maintenance involved.
Houses need to be cleared of old nests at least yearly, and you’ll need to
monitor it so other birds don’t take over.
Last year over a
million families put up Martin houses. Here, it’s best done iun the spring.
Also, several neighborhoods and communities in north Texas have become Purple
Martin landlords. They depend on us!
