Audubon NY Birds Mean Business cards
"Birds Mean Business" cards are designed to show businesses and municipalities that bird watchers are contributing to the local economy. Birders are encouraged to leave the cards with local businesses, municipal officials and Chambers of Commerce in the places they visit. See Audubon New York's press release about their Birds Mean Business campaign.
The PDF contains examples of two types of BMB cards that your Chapter can use as templates for creating its own.
