American Flamingo by Greg Homel

When you go birding, don't forget to let people know "a birder was here". Sign guest books at wildlife refuges and other birding locations. This helps refuge and park officials estimate the number of people visiting for birds and helps them justify budgets and park usage.

You can also leave behind a calling card at businesses you patronize during your trip to tell the owners that birders are helping to support them and will return as long as bird habitats are maintained. A birder's business card is available for download here.
