Cambridge : Règlement no 171-13, art. 6.5 — Construction Standards for Lofts

Construction Standards for Lofts:

• Any owner of pigeons or other birds shall ensure that lofts used for the containment of the pigeons or other birds are constructed and maintained so that the ingress to the loft can only be obtained by what is known as a drop trap opening or a series of bobs, which shall be so installed as to prevent their being used as a means of egress by the pigeon or other bird.
