Catching a toe on Mama's sweater, I can relate. Venus likes to play and chase my fingers or whatever I have in my hand and twice she has gotten her foot caught or snagged on my shirt and she screamed. Typically she is in my lap when we are playing, she hops and runs so she has gotten her toe caught and either she was surprised by it or it did hurt. Each time I've checked her over thoroughly and she runs for whatever toy we are playing with and I know she's fine. I hope it is something that seemingly simple. Poor Poppie, I think she has realized she's done something wrong and I agree about amazons being like toddlers, Buddy is a 25 year old 3 year old, lol. I hope Your wife comes around but I know she is very fearful right now.
I'm 99 % sure that's what happened. My wife had a wool sweater on and wool has those loose fibers in it that tend to catch the claw/talon. I honestly don't think it was hormonal as I have seen hormonal in many birds and this was more of a fear attack than hormonal, like being trapped.
Poppie is the Alpha bird in the flock, the boss, and she lets it be known. Doesn't attack the other birds, but she's first in everything and rest back off.
She tried to use that on me once, and I established that " I'm the Alpha of the flock". I used a technique that I was taught in handling falcons and Hawks, it establishes dominance over the bird and as the Alpha as well.
When a parrot gets biting or cranky you reach under both wings cupping their brest and lift them straight up over your head then down again flipping them on their back. You'll get a bite on the hand, then release them back sitting up. I kiss them on the head quickly as I do it to assure them they are not being harmed. I don't recommend everyone doing this as they will bit hard going thru this. It doesn't hurt them, it's a technique that is used where the nerve under wing that goes to back part of wing on body to the mid portion of the back is stimulated and in the wild, mates (males) do this to females and even other males to establish dominance and territory as well as first pick of mates.
I have done this with all my birds....never bitten ever now that I established that. All birds are careful and gentle. They do get cranky now and then, but know not to bite the alpha.
as for the incident with Poppie and my wife....My wife has pick up poppie today.. Poppie laid her head on my wifes tummy. Very cute, but still My wife did point out that big bandaid on her neck to poppie...I think poppie knows.
My wife is a former Vet, so she's had her share of being bitten or clawed.
Handles snakes, Big ones too, and will tell you about the crazy cat in the vet office that could run on the ceiling. LOL....Poppie will be fine...wife as well. Just an unfortunate incident, and a lesson learned in certain clothing.
To poppie, I'm Alpha, she doesn't dare bite me ever, except the nite she bit my wife, but I think because she was caught in wool with her claw..
