If you're planning to join them for the first time, it's better to know the dos and don'ts. According to America Birding Association, here are three main rules in bird-viewing:
1. Respect birds and their environment
Knowing what kind your environment you're in is one way to go. Observe the habitat and conservation around you and identify the animals and bird species inhabiting the space.
Avoid exposing the birds to danger and reduce disruption to the environment by checking whether your viewing or photography equipment is safe for them and the general wildlife. Maintaining the habitat and the green space is also helpful to improve the quality of their habitat.
2. Respect the birding community and its members
Interacting with birding communities and members helps a lot in improving your knowledge and doing the activity better. Learning from their experience and sharing your observation and research will make a good impact on the community.
Practicing ethical bird-viewing will also gain you respect from the community. Use the opportunity to improve your skill and introduce more people to your group.
3. Respect the local rules and the rights of others
Some properties and areas are limited to public use and do have restrictions. Respect the boundaries by not trespassing private property without permission.
You should also respect your birding area and be especially aware of some bird species, as they may be near-extinct or rare species that require sensitive treatment. Be mindful of where you're bird-viewing and follow the local rules.
