My cockatiel only bonds with one person

My caique 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.

I showed this post to my bird and they looked at me with zero remorse. They know what they're doing.

Have you reached out to Bird Sitting Toronto? They really know their stuff when it comes to bird care.

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

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

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

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.
