Parrot is shredding paper and putting them behind her/his wing

So i saw my parrot shredding paper and putting it under his/her wing, I think she's planning to make a nest inside her cage
Is this a sign that he/she is a female? as he/she is showing nesting behaviour.
(Sorry for the shaky picture)

This isn’t the first time I’ve seen this happen I’d just have a good laugh at it.

Definitely nesting behavior---hormonal...my bird once did this with a cracker....No huts, tents, dark spaces, blankets etc, and no petting outside of head and neck area. Also, 10 hours of solid sleep nightly, plus lots of activity/non-cuddle interaction outside the cage,

My female lovebird always did this when she was hormonal and she laid eggs and we didn’t know how to stop the behavior. Follow the above advice - it works! Also don’t let her get any paper, cardboard, or anything that she could use to make a nest. Good luck!

Yup! Learn something new everyday!

Ours do this *all* the time! We paper the bottom of their cage with junk mail and they turn it into strips and make little 'whirlpools' out of them. I'm sure it's related to nesting behaviour, because if I allowed them a nestbox, this is what they'd do to construct a nest. As it is, they make long (twelve-inch) strips, tuck them into their tail feathers and fly with them up to the highest perch. Then, they'll sit and slice up their long streamer into inch-long pieces, which they drop and lose all interest.

Since I don't give them a nestbox, the Lovies just chew and chew on their papers and make a whole lot of shred. It doesn't worry me unduly because in every other respect they're in great health.

I've noticed they *much* prefer chewing their papers to stripping bark from branches like our larger birds do. Likewise, they're not much fussed on cardboard or corncobs or bits of untreated timber. They just like to strip paper. I wouldn't worry unless your bird is showing other ritual or repetitive behaviours that suggest a 'nesty' or overly hormonal mindset.

Remember: it's quite normal for a bird to be 'hormonal' (ie. obviously sexually motivated) at certain times of year. Some birds are like it for all four seasons and Lovies are a great example of that. What's not desirable is for your bird to become distressed or obsessed by the behaviour in a way that makes life upleasant for him/her. This is why we often advise people to remove obvious triggers to sexual behaviours as it's not really kind to foster permanent frustration in your bird.

Only you can judge. If you're worried that your bird is getting carried away and a bit 'sex mad', then remove the papers. If you think birdie is fine and happily occupied with paper-chomping, then leave it be and just keep an eye on things.
