Need help identifying your martins?
These life-size color photos follow a martin nestling from hatching day through fledging day, a total of 30 photos. Laminated to make a valuable tool for landlords, especially when paired with the Prognosticator.
Use the photos to determine age of nestlings after hatch, and know when they're due to fledge.
This set also includes Adult Plumage Photos for martin sex and age identification. Landlords can use a 3-hole punch and place the 8 1/2" pages in their field notebook.
note: we experienced a rise in the cost of our photos since producing our catalog and have had to raise the price of this item
