The husbandry of falcons for return to the wild

The husbandry of falcons for return to the wild triggers egg-laying, and how to provide that trigger artificially. Here, the problem is infertility. Deeper water in which to copulate, more protein or different vitamins and hormones, some method of restraint other than pinioning, might provide the answer. Experimentation would be valuable. We suggest that the need is to combine the highland flamingos currently in captivity in a few carefully selected places, mark them so that they are easy to identify, and then pay for some thorough, trained observation. We need to know which birds are feeding, and for how long, which are being chiwied, which are copulating successfully and where, which are changing mates, whether the sex ratio is even, and so on. With those queries answered, we might be able to recommend a system that results in captive-bred Andean and James' flamingos being available to all zoos.

Abstract

triggers egg-laying, and how to provide that trigger artificially. Here, the problem is infertility. Deeper water in which to copulate, more protein or different vitamins and hormones, some method of restraint other than pinioning, might provide the answer. Experimentation would be valuable. We suggest that the need is to combine the highland flamingos currently in captivity in a few carefully selected places, mark them so that they are easy to identify, and then pay for some thorough, trained observation. We need to know which birds are feeding, and for how long, which are being chiwied, which are copulating successfully and where, which are changing mates, whether the sex ratio is even, and so on. With those queries answered, we might be able to recommend a system that results in captive-bred Andean and James' flamingos being available to all zoos.
