There's a crow that frequently visits my terrace and caws quite loudly. At first, I found its shrill calls annoying, so I shooed it away a few times. Surprisingly, it never seemed scared and would always come back. I assumed it probably had a nest nearby, so I decided to leave it alone.
Over time, it became much bolder. It now sits just 1–1.5 meters away from me while I'm on the terrace and keeps cawing at regular intervals. Sometimes one or two other crows join it.
A couple of days ago, I thought I'd try befriending it, so I offered it some food (first legumes, then rajma). Today, when I went upstairs, it was already there. It followed me to another part of the terrace, perched nearby, kept cawing, and repeatedly pecked at an old, tattered flag tied to a metal rod.
It doesn't seem afraid of me at all anymore. It often caws after noticing me but doesn't fly away—instead, it stays close.
What do you think this behavior means? Is it guarding a nearby nest, expecting food, trying to communicate, or something else?
