Don't worry for one second about offending me! I have the thickest skin and have been doing this for a looong time and have gotten all kinds of reactions - from mildly snippy to outright rude. I actually appreciate the arguments... I love to debate.
I am VERY surprised, though, that you have never heard of the honeymoon period! I mean... this is common knowledge in the parrot community. Granted that first timers would not know about it unless they have done research prior adopting but anybody who has done rehoming or adoption knows about it (mind you, I don't agree with hands-off with babies)... I am including two links only because all the other links are not allowed here but there are millions of references to it everywhere:
https://blogpamelaclarkonline.com/tag/h ... h-parrots/https://birdtricksstore.com/blogs/birdt ... new-parrotAre there sweet ekkies? Of course there are! I never meant to imply there are not. There are sweet-tempered birds in every species - same as there are mean ones! I was just trying to point out that not all ekkies are nice as you seem to believe, and telling you of my own personal experience with them - and I can assure you that I have no reason to lie about this. Elsa, the SI female, was rehomed to my (then) avian vet tech because she fell in love at first sight with her husband, a mammoth of a man -a stone mason- with a HUGE beard. And Elsa had been raised by a woman so go figure! And Romeo was sent to an ekkie sanctuary because rehoming him would not have worked out as he hated all humanity (never did find out what his background was as he had been brought to a pet place for grooming and abandoned there -they even gave a fake name and phone number) - and, last time I heard, he was doing great there (this was years and years ago).
And I am not telling you 'not to try', I am telling you that it will behoove you to understand what the parrot is going through and what is going through his mind right now and not to ask for anything until he takes the first step to up the relationship a notch (please, read about the honeymoon period). The 'don't ask for anything' during the honeymoon period is what is recommended and what I do because I have found it works like a charm. All my parrots came from somewhere/somebody else and almost all of them had one issue or another (screaming, attacking, etc) why they were given up and they are all doing great, no aggression, no screams, no nothing. This tells me that the method works and that's why I recommend it. But it is up to you.
You might also want to do research on the following:
avian photoperiodism
avian endocrine system
avian reproductive system
this is knowledge that is essential to keeping a parrot healthy and happy.
As to diet, yes, you are 100% correct that most people feed their ekkies pellets and/or seeds. And that's why they all end up with hepatic lipidosis and die young. I posted a story not too long ago with the picture of a 6 year old ekkie that already had the dreaded black spots on its plumage that indicates advanced liver disease - and at only 6 years of age! The oldest ekkie in captivity that I have read or heard about was a wild-caught (infinitely stronger, healthier and hardier than any captive bred) kept in an Australian zoo (which means the same climate as its natural habitat and the same plant material to eat) and he died at 30 years of age. Check it out, you will see that you will find very, very few birds still alive over 25 years of age and all of them have health issues. The truth is that these birds should've never been bred for the pet trade... their diet is too specialized to reproduce in captivity. I don't know if you have read or have heard of one of the first and best known breeders of ekkies, Ms. Laurella Desborough (a HUGE promoter of them as pets - big surprise that the person who promotes is the same person who exploits them for money, right?) but we, rescuers, used to refer to her as Cruella Desborough. Not nice, I know... but we all love birds and thoroughly dislike people who abuse them or exploits them.
Look, I don't mean to rub you the wrong way... I can only tell you what I know about them and hope that, when you find something I say is not what you have heard or read, that you do more research about it. But the right kind of research - meaning, not breeders', birds as pets' or 'fluff' sites but scientific ones: biologists, ornithologists, studies, etc. Places where the information is based on science, fact, tests results and observation done by professional people who have trained about it. The others just give you their opinion and, in most cases, there is an ulterior motive for it...
One more thing I forgot to mention before, be careful with veggies that are high on salicylates, some people believe they have an intolerance to it.
