This calendar was assembled by the Andrew Troyer family who are well known respected experts of purple martin research and development of sustainable purple martin colonies and housing.
You won’t find online research as the Troyer’s are Amish and have published many books on purple martins as well as manufacture purple martin housing and products.
Spiral-bound 8 x 11 pages of calendar sheets and pictures for each month of the year renewed each January for the new year. Pictured as 2020, you will be sent the upcoming year as soon as it is available if you order within or after the 4th quarter of October-December of the previous year. If you order January-September, you will be sent the current year.
Note: While the Troyer family doesn’t recommend the capture and holding of purple martins as shown in some of the pictures, the pictures they do show are part of the ongoing research and banding to track patterns of purple martin colonies.
