My cockatiel only bonds with one person

My cockatiel absolutely LOVES my partner but hisses and lunges at me, and I'm the one who feeds and cleans! Anyone else deal with this? How did you build a relationship with a one-person bird?

If you're in the Beaches, check out the avian vet on Dundas St. They're amazing with cockatiel specifically.

Update: took everyone's advice and things are improving. Noodle is slowly coming around. This forum is the best.

Interesting take! I see your point but I've had a completely different experience. My cockatiel actually...

I've had birds for 15 years and I've seen this many times. In my experience it usually comes down to hormonal season — spring is brutal.

Have you noticed any other changes? When my cockatiel did this they were also plucking feathers.

What worked for me was adding a full-spectrum Arcadia UV light near the cage. Took about a week but my cockatiel responded really well to it.
