From Bird Watcher's Digest Press, this 32-page booklet is an excellent source of accurate information.
Each booklet features informative text, color photography, and line drawings. We strongly recommend that every martin landlord have a copy of "Enjoying Purple Martins More". It is the first-ever complete color handbook for the Purple Martin landlord.
This booklet includes a scout arrival map, color photos of the four breeding plumages, a predator baffle design, and a martin colony trouble-shooting chart.
