Purple Martin Nest Material

So what do you use to put in those martin houses and gourds? Many of the available choices that some folks may use work great, some are a bad idea.

Good

Typically the most commonly used prenest material is Pine Straw. Pine straw is just pine needles. It may differ in length and color depending on what kind of pine tree the needles are from but usually pine needles from Longleaf pine, Slash pine or White pine.

Leaves can also be quite water repellent. It really depends on the leaf. Oak are good. Small and flat they are safe.

Corn Fodder which is dried cut up corn stalks

Bad

Grass clippings are a bad choice. First, the grass absorbs water. This in itself is bad enough but then it can mat down and become compacted to the point where water will not easily penetrate. Making your gourd a pool of death.

cedar shavings, though easy to find at any petstore and quite cheap, are not a good choice. They absorb water and stay wet. If you ever use shavings in a cage for a rabbit or hamster, you know! Though I have used it in a pinch, you should try to avoid it.


Depending on what is around you will notice the martins at your site bringing many things to use as nest material. Long ornamental grasses, reeds, hay, even nails have been found in nests. Yes, I recently saw a photo of a martin nest that had over 100 long metal construction nails in the nest. What have you found or used in purple martin nests???

The most important thing to remember is that American’s have been altering the nature of purple martins for hundreds or perhaps thousands of years. Since martins have lost the instinct to nest in a natural cavity, we have a responsibility to care for these birds as part of our heritage as American’s…whether Native American, North American or United States of ‘American’.
