Please help my case!!

[My post keeps getting filtered out by Reddit] I have pigeon couple is released together from our window from roughly 3 days ago, only Pigeon A (probably male) of them came back. Pigeon A is yelling and moaning for the return of Pigeon B (probably female, who didn't came back), he also search everywhere around my home in NYC. Pigeon B have done overnight stays outside before, but not this long (it is already been roughly 3 days).

I also noticed Pigeon A and Pigeon B don't always fly together back home despite being both released at the same time. Please, I am begging for help because Pigeon A is being rooster because he keeps interrupting me sleeping in the morning despite putting in him different rooms.

Pigeon B have a black knot on its leg, to identify her as someone who has a owner.

Is there any resources including websites regarding lost pigeons (the only social media that I use is Reddit, please help even if I need to use social media outside of Reddit)?
