17 weeks isn't old, my girl is only a few weeks older than that if true.
You can tell their general age (very roughly) by two things, on female eckies.
- Babies often have light streaks in their beak (where as mature adults it's fully black)
- Their irises (and therefore eyes) are dark when they're young, white when they're mature.
Babies often have light streaks in their beak (where as mature adults it's fully black)
Both of these things often begin to shift at about 12 months of age but the age at which this settles can vary per individual. But if your parrot has both dark eyes and a light-ish beak then you can safely say she's probably under 2 years old.
I dont know how you'd know for sure without consorting with an avian vet (or of course your bird's paperworK)
Now I am still getting to know birds so I can't give you extensive advice on her biting/aggression but I can give you some of my own experiences.
When Remi bites me, it seems to be because
- I go to pet her on her head, which she's not into, and I ignored her leaning away as a 'no'.
- I have stuck my hand on her cage while she's playing (she will often growl or stick her feathers out before a bite)
- She's in the middle of playing/chewing something, getting carried away and my hand gets in the way
Generally the best way to avoid the bite (at least initially) is to avoid getting to the point where a bite occurs at all. If for you it's because you put her on top of the cage, and you have to stick your hand up to get her off, then don't let her play there.
If the person who sold you the bird said he hadn't handled her in a while - having hands all of a sudden might be a bit overwhelming for her. So I think your interaction with her in her cage is the best point of action for now, as it gives her a safe place to watch you and be comfortable.
If she's young like you say - then her screeches are either for attention or hunger. When my bird hears the microwave she screeches the house down, even if she's just eaten! When she is starting to get hungry she'll start squawking, and often makes these "double" squawks which we've noticed only happen when she's hungry. As soon as she's eaten, she settles down.
What are you feeding her? it's possible the trip home has made her 'regress' from her weaning progress, and if you're feeding her solids and she's not showing interest she maybe hungry for some comfort foods. If that sounds right to you, try steaming some vegetables and making them into warm mash. My girl gobbles it down - and only now is she comfortable enough that she's starting to experiment with solids (and even then, her favourites are still soft)
The other reason Remi screeches is for comfort. She loves my partner and when she's home, she will always squawk when she's with him. I'm not quite sure what it means yet but I think it's just a bit of excitement to be with her favourite person.
She will sit on his shoulder and just squawk herself to sleep. Often in her excitement when we get home from work, she'll just be so worked up she can't even eat, and she'll just squawk until she's a bit more relaxed, and then quietly eat.
I'm told some of these squawks will recede once she matures - but I'm not sure which of those are going to go and which ones I need to train into talking instead. It is likely you'll experience the same thing if you have a 17 week old.
This is probably a lot of info but I hope it helps in some capacity. Have a read through more of the eckie forums as many people have gone through what you're going through before.
Also, I can't see your avatar here but i can see a tiny version on your profile. Hmmm.
