Do older amazons fail to go into there normal hormonal season?

My Bingo (age about 34/35) never showed the normal signs of mating interest that usually show up in December January time frame.

I know 34 years old is not that old for an Amazon but it's possible I did not get the truth about his age when I bought him. I was told he was only 1 year old in 1986. He had no yellow on his neck at that time. But within a 1 1/2 years of having him he went through puberty.

He seems health in all other respects normal appetite, normal droppings and normal activity.

Could his missing of the breeding season be due to the new bird (Merlin)?
I don't see why that would be but it's the only thing different this year from every other year.

Yup, he is likely older than you had been told by 3 to 6 years.
Last year had my 21 year old near missing last year's season. This year, he is early. only difference is the weather. Not sure what difference between the two years have been for you but worth double-checking.
Our 48 year old would have chased Julio around the house had they lived during the same time. So, your Amazon is off his game for one reason or another.

Interesting. I wonder if birds do go through a sort of menopause? My Red Bellied Parrot will be 25 this year. I’ve had him since he was a juvenile. The past couple years he seems to not have the hormonal crazies. He’ll still bite hard occasionally, but that’s just the Poi in him. He still will do the dance and regurgitate now and then, but has become much easier to handle. He isn’t showing any signs of aging, just no supercharged hormones.

Obviously not an Amazon, so not trying to hijack your thread but basically same question .

For what it's worth...
The Rb turns 35 in May, and his hormone patterns haven't changed (since he became a rooster at age 3-4) as far as I can note. This means that he is especially maniacal in late summer, but at other times of the year, sometimes just gets 'in the mood' for no apparent reason and has to court me and do his thang for a few minutes. I'm sure of his age since I've had him since he was a few months old.
