Areas which are at present alienated but which a few of the species might inhabit if its numbers greatly increased but such areas in course of time may disappear. Areas at present uninhabited by the species but capable of carrying a considerable number of the species. These areas for various reasons are not liable to be decreased to any great extent and will probably remain as permanent areas of possi- ble habitat to the species as numbers increase. Areas entirely and permanently alienated from the species and never likely to be inhabited by the race because of lack of food and cover and too wide a difference to enable the species to adapt itself to such unsuitable surroundings. Areas in red: Even should the species so increase in numbers as to be forced out into such areas I doubt the few birds which could find food in the area would long survive natural enemies (hawks, etc.) because of lack of cover, etc. in which to escape as it is a slow flying rather clumsy species in the open and appears very unhappy in such surroundings.
