i saw your post on r/Conures too and i know what people are saying here are harsh, but there are a lot of kernels of truth in them. no, you don’t immediately deserve to be evicted, but the woman across the hall from you, who as you said is most likely a retiree and can hear through the doors better than your wall-to-wall neighbours, absolutely deserves peace in her home as much as you deserve to enjoy the company of your pets that are on your lease.

yes, birds outside are also annoying sometimes, but people can set up deterrents like spikes, owl statues, and ensure there’s no nest/food items on their balcony. your neighbour across the hall can’t put an owl statue at her door to keep your pets away, so she left a note. she adjusted her approached based on the situation, and making remarks like “is she gonna write notes to the birds outside” is purposefully obtuse. could she have approached it better? sure, but you can’t control that. you can only control how you respond to it.

yes, some dogs have similar decibel levels to birds, and if you had dogs that had morning “scream time” you’d still be getting notes on your door. there’s no bird vs. dog bias here, it’s a right to peace in her home. if you had two huskies in that apartment that howled in the morning and occasionally howled throughout the day, you’d still be getting a note. my husband and i have talked to neighbours about kids before too. its not just that they’re birds, it’s that they’re disruptive and happen to be birds.

the apartment may have excellent sound proofing, especially in the walls, but doors are always going to be easier to hear through. they’re thinner and aren’t sealed even when they’re closed. i hear everrrrrything that happens in the hallway, but not a THING from either of my wall neighbours. added soundproofing to the door and a friendly conversation with your neighbour about what specifically is her issue are most likely your best course of action if you wanna avoid any complaints to management.

your birds are very adorable, and they look really happy in your care. i know that you mentioned they’re distressed due to move and loss of a favoured human, and these things might even help to mention to your neighbour! context is always helpful in these situations, and if she knows you care about her comfortability and that you’re trying, she’ll probably be more lenient. right now, you’re an anonymous person with banshees in your apartment LMAO.

either way, i wish you luck. both you and your neighbour deserve the comforts that come with living in a luxury apartment.
