Promote the welfare of birds and their environment.
Support the protection of important bird habitat. To avoid stressing birds or exposing them to danger, exercise restraint and caution during observation, photography, sound recording, or filming. Limit the use of recordings and other methods of attracting birds, and never use such methods in heavily birded areas, or for attracting any species that is Threatened, Endangered, or of Special Concern, or is rare in your local area; Keep well back from nests and nesting colonies, roosts, display areas, and important feeding sites.
In such sensitive areas, if there is a need for extended observation, photography, filming, or recording, try to use a blind or hide, and take advantage of natural cover.
Use artificial light sparingly for filming or photography, especially for close-ups.
Before advertising the presence of a rare bird, evaluate the potential for disturbance to the bird, its surroundings, and other people in the area, and proceed only if access can be controlled, disturbance minimized, and permission has been obtained from private landowners. The sites of rare nesting birds should be divulged only to the proper conservation authorities.
Stay on roads, trails, and paths where they exist; otherwise keep habitat disturbance to a minimum.
Group birding requires special care – Group Leader Responsibilities

Respect the interests, rights, and skills of fellow birders.
Keep groups to a size that limits impact on the environment and does not interfere with others using the same area.
Ensure everyone in the group knows of and practices this code.
Acknowledge that professional tour companies bear a special responsibility to place the welfare of birds and the benefits of public knowledge ahead of the company’s commercial interests.
