Member Workshops

Our workshops give our members hands-on experience while expanding knowledge of bats and their unique conservation requirements at locations of special need worldwide.

Ambassadorial Appearances

Wherever we go, Merlin and MTBC serve as captivating ambassadors for bats, often making a lasting difference in each country visited. We provide media appearances, public lectures, training sessions and much-needed conservation advice, as well as photographs essential to public education.


Student scholarships are unsurpassed in their contributions to bat conservation. Most of the world’s more than 1400 species remain unstudied beyond taxonomic descriptions. Research to document their vital ecological and economic roles and put people’s superstitious fears in perspective is urgently needed to reverse alarming decline.


Bat House Certification Program

An unfortunate number of manufacturers market bat houses that are inadequately designed, made of unsuitable material, or fail to provide proper instruction to attract bats. To combat this, MTBC has started a Bat Certification Program for interested vendors. Merlin Tuttle’s Bat House Seal of Approval strengthens confidence in customers wishing to purchase a quality product. The seal is a visible commitment, assuring both manufacturer and purchaser, that the product meets the criteria expected by experienced professionals. If you would like to be included in our list of trusted retailers, please use our Instructions for Applicants
