A total of 24 criteria aspects have been established in order to attend the needs that birders have when travelling worldwide.
One feather means that an establishment complies with the five basic criteria required by the Lonely Birder Approved hallmark. The rest of the 19 criteria aspects are optional and they all depend on how many of these are fulfilled by the establishment which will vary the number of feathers awarded to them.
N.B. All establishments on the LB website support the protection of birds. In the case of an alleged professional misconduct by an establishment in the LB directory (i.e. the destruction of bird nests from roofs, facades, etc), the establishment will be taken off the website immediately.
