Hi!
Eclectus reach adolescence at about 24-36 months for small subspecies and as late as four to five years for the large subspecies. This is a generality, and individual birds may reach adolescence earlier or later than this.
As far as how many cycles, etc....small subspecies seem to have four a year...two strong and two weak, IMHO. Larger subspecies seem to have three. But for every subspecies, this time of year, whether in the Northern or Southern hemisphere, is a very strong cycle. Again, not all Eclectus will have their strongest cycle this time of year, but many do.
As far as how do they behave....
Alot of it has to do with the individual bird, of course. There are some Eclectus who have very pronounced hormone cycles and others might just become a bit cage territorial and defensive for a few days several times a year. I know some people whose fully mature male Eclectus show virtually no signs at all.
One thing that is important, IMHO, is to learn all you can about how male Eclectus CAN behave when they are hormonal, and the approximate age that is most likely to be the onset of adolescence for your Eclectus' subspecies or, if the subspecies is not known, for the size of the bird (smaller birds - younger; larger birds- later). Once you know what kinds of behaviors can happen with hormones, the better prepared you will be to manage them very quickly. In other words, if you are aware, and if your boy starts to behave strangely - aggressive, cranky, defensive, etc - then you will have some ideas of what to do...for example, do not behave impatiently in return, as it only escalates the behavior...diffuse it with a quiet, patient response.
If a person behaves with anger or impatience, the bird perceives that response as a challenge and "gears up" to defend himself/his cage/his mate/his territory. People who are not aware of this kind of behavior may accidentally make it worse. But by learning about it, you can, in many cases, recognize it and make it minimal.
There are two answers to your question...one is, TO ME, it seemed that after the first few hormonal cycles, our male SI's behavior did start to mellow out. I think about human adolescence and how a teenager can be a loving child one minute and an angrily independent and rebellious person the next with very little transition. But when the young person matures, that kind of behavior "mellows out" and the person is a very even tempered adult. So answer number one is Yes, they mellow out.
The second answer is...they mellow out, but we also learn. We learn what to do, how to manage and how to handle...how to recognize the signs that our individual Eclectus is entering, is in, and is going out of a hormone cycle.
So between the rising of our learning curve and the mellowing of the bird as he matures, hormonal behavior in males is often very predictable and very manageable.
For readers with females, female behavior is also predictable and manageable, but IMHO, their instincts are more - how shall I say - urgent. Females are very much the "business end" of the Eclectus breeding partnership - they find the nest (a girl without a nest cannot have babies - since she wants to have babies, she has to find a nest...and she will be very insistent about doing that during strong hormone cycles), they have to prepare the nest, they have to call to advertise that they have a suitable nest (to attract males and to discourage competing females), they defend the interior of the nest and babies from other birds who want to occupy it, from raptors, from reptiles and from rats....so they can be very urgent and insistent in their hormonal behavior...but it, too varies by individual (some females are only a little bit cranky and reluctant to come out of their cages for a few days four times a year, and others do alot of nest seeking and calling). The behavior of the females also becomes easier to manage due to "mellowing out" and the increased experience of the owner.
The very good news is...here at this message board we have alot of information about hormonal behavior, ways to prepare for it, identify it and manage it!
There is every reason to expect that your relationship with your Eclectus as a baby, juvenile, adolescent and adult will remain affectionate and wonderful for you and your bird!
We hope this information was of some help to you.
