Thanks to member and donor support, the Purple Martin Conservation Association is hard at work helping to ensure the future of Purple Martins.
As the largest organization devoted to Purple Martins, the PMCA has been working to protect the species by leading research and studying Purple Martins for over 30 years.
By conducting and supporting world-class martin research, we are learning more than ever about this amazing species! Through partnerships with universities, corporations and other governmental entities, the PMCA remains the largest advocate for resources to support martin conservation.
Not only are professional teams conducting research, but individuals are also participating through the PMCA maintained citizen science programs. Additionally, the PMCA offers annual research grant opportunities to students, professionals and individuals seeking to better understand the mysteries of Purple Martins.
Through these partnerships, martin research is happening not just locally at the PMCA headquarters, but actively throughout all of the Western Hemisphere! It is a particular challenge to understand more about the migratory movements and wintering habitats of martins in the tropics. As population estimates continue to decline year after year, it is necessary to uncover as much as we can about Purple Martins within all of their range. The PMCA is committed to facing those challenges; developing partnerships in Central and South America are generating very exciting opportunities for collaboration and discovery.
In conjunction with our partners, the PMCA remains committed to identifying conservation issues and developing solutions to maintain a healthy and sustainable Purple Martin population.
