An unexplained and precipitous decline struck the bandtail pigeon about ten or twelve years ago, from which it apparently has never recovered. Although hunting was undoubtedly part of the pressure exercised against these birds, it in no way accounted for their sudden and dramatic decline in numbers. This decline may gradually be reversed, since more and more of these birds are being seen. It is well known that animals with a high reproductive capacity can endure much heavier losses to their population than can those with low or very limited reproduction, such as the bandtail, which normally lays only a single egg. The mourning dove, on the other hand, lays two eggs at a time and may raise as many as five or more broods in one year. Take this one step further with the scaled or Gambel quail, which may lay up to 12 or 15 eggs, and it can readily be seen that the population of bandtail pigeons can never endure the losses that the much more prolific mourning dove and quail can. The same might be said by comparison of elk and deer. Elk do not bear their first young until their third year, and then the cow may not bear young but alternate years until her seventh or eighth year; by that time she has begun to decline in vigor; in her total life she may not produce more than four or five calves. The mule deer, on the other hand, start bearing at the age of two, with their first birth normally single; from then on, twins are usual for the rest of the doe’s life. Thus, deer have a considerably greater reproductive potential than do elk or bighorn sheep, which have one young at a time. The fleet-footed antelope of the open rolling plains is another example of fairly high reproductive capacity, since they breed earlier than do deer and normally bear twins. Antelope are confined to the more open country where their prodigious running ability and marvelous eyesight stand in good stead in protecting them against their natural enemies. The wild turkey, classified by law in New Mexico as big game, is found throughout the mountainous areas of the state, not excepting some of the desert ranges. New Mexico is one of two states fortunate enough to possess three of the five forms of the wild turkey known to the United States: the Merriam turkey, found in the higher elevations of the mountainous areas, usually the ponderosa forest; the Rio Grande turkey, confined to the watercourses of the eastern plains; and the fairly rare Mexican turkey, found in the Animas and Peloncillo mountains of extreme southwestern New Mexico. In Hildalgo County these mountains are actually largely Mexican in both flora and fauna. Some of the rarest, most beautiful birds of North America are also found in this area and nowhere else in the United States with the exception of southeastern Arizona.
