In order to be able to correctly compose a good pair for parrot reproduction, it is necessary to have sexed birds with certainty. The most reliable solution is DNA sexing. This is done by sending a sample of a few freshly torn feathers to an analysis laboratory in a small airtight bag provided for this purpose (previously sent by the laboratory). For more information you can get information directly on the site of a laboratory.
However, with some bird species, naked eye sexing is possible when the birds show obvious sexual dimorphism, for example in eclectus.
Once we have made sure to have a pair, we can therefore begin to initiate the phase of presenting the birds to each other:
1st solution: introduce the birds, previously chosen, together in an aviary, on neutral ground. Most of the time the birds will get closer very quickly, and over time get used to each other. After some time, when the breeding season approaches, they may reproduce, if they feel like it.
2nd solution: that it is better to use for large birds, such as cockatoos, macaws, amazons or grays. If possible, it is really wise to be able to place a group of young birds, in a common aviary, and to let them develop there together, so the pairs of birds will form according to their hooked atoms, as naturally as possible, as they would have done in nature. We thus obtain pairs of birds getting along in tune, and we therefore avoid certain tragedies that can arise when we put together 2 birds that do not get along. Some males can, under the effect of great sexual arousal, end up killing their female (this case occurs relatively often in large cockatoos). This solution therefore has its advantages, but it requires being able to accommodate over a more or less long period, several individuals of the same species, which unfortunately is not given to everyone.
3rd solution: we breed several pairs in colony in a large aviary. We therefore place several male individuals and several females together. Several nests are made available to them (more nests than there are potential pairs) and the birds are allowed to mate with whomever they see fit. This solution requires relatively large installations and a set of birds of approximately the same age, to avoid certain clashes between young males unable to defend their territory against elders (the same goes for females, which can be much larger. mean to each other!)
In addition, it is advisable in most cases to present a male older than the female, however this depends on the species of the birds, because it is essential in certain cases to put together a female older than her male, in order to avoid any problem. This rule is therefore not to be taken literally, it is necessary to learn well beforehand, on the customs of the species in question, which one plans to put as a couple.
In conclusion, we can therefore say that in the majority of cases, composing a good pair of birds does not turn out to be very difficult. It is necessary to take the dispositions to acquire sexed birds, and this in a reliable and certain way! (beware of wacky sexing). When you compose a couple of large parrots, which can be aggressive, it is essential to closely monitor your couple, especially during the breeding season, because even a couple together for years can have a violent spat overnight. A good breeder will therefore always be attentive to his pairs.
