Research of Purple Martin
Your generous donation will play a crucial role in helping us gather essential research data on Purple Martins, allowing us to gain a deeper understanding of their specific needs and ensuring that we can effectively address any challenges they face.
Migration Tracking
Purple Martin migration is being meticulously tracked using geolocators that record sunrise and sunset times. Before the fall migration, these birds are fitted with devices that are later removed when they are recaptured after the spring migration. By analyzing the daily recorded light levels, scientists can approximate the global position of the Purple Martins, plotting their migration routes, timing, and non-breeding locations.
This important research is conducted in partnership with Bridget Stutchbury, a scientist from York University, along with her dedicated staff, the Purple Martin Conservation Association, and supportive landlords like founder Paul Mammenga. The application of this technology to Purple Martins in South Dakota began in 2011, with 33 geolocators deployed that year. The findings from this research are significant not only for the conservation of Purple Martins but also for the broader fields of science and ornithology.
Natal Dispersal
A natal dispersal study is currently underway in South Dakota, in collaboration with landlords from Minnesota and Saskatchewan, Canada. This study aims to gather valuable data from any landlord willing to observe Purple Martins through binoculars for leg bands.
In 2011, two banded male Purple Martins successfully paired, nested, and fledged young from Paul Mammenga’s site near Columba, South Dakota. These males were originally raised and fledged from Willmar, Minnesota, and Saskatoon, Saskatchewan.
We encourage all landlords to keep an eye out for any banded Purple Martins at your colony sites. If you spot any, please let us know! We can assist you in retrieving information from the leg bands. You might be surprised to discover one or more banded individuals in your area!
