(1) The primary consideration for raptor housing facilities, whether indoors (mew) or outdoors (weather area), is protection from the environment, predators, and undue disturbance. The applicant shall have one or both of the following facilities:

(a) Indoor facilities (mews) shall be large enough to allow easy access for caring for the raptors housed in the facility. If more than one raptor is to be kept in the mews, raptors shall be tethered or separated by partitions and the area for each bird shall be large enough to allow the bird to fully extend its wings. There shall be at least one window, protected on the inside by vertical bars, spaced narrower than the width of the bird's body and a secure door that can be easily closed. The floor of the mews shall permit easy cleaning and shall be well drained. Adequate perches shall be provided.

(b) Outdoor facilities (weathering area) shall be fenced and covered with netting or wire, or roofed to protect the birds from disturbance and attack by predators except that perches more than 62 feet high need not be covered or roofed. The enclosed area shall be large enough to insure the birds cannot strike the fence when flying from the perch. Protection from excessive sun, wind, and inclement weather shall be provided for each bird. Adequate perches shall be provided.
