I have an update since my post from yesterday.
My husband believes the white flashing right on top of our window wasn’t there before yesterday’s gutter work. I keep hearing chirping which makes me believe they actually trapped the nest behind the flashing. Mom still comes back with food for them.

I contacted the apartment complex and asked to send a contractor if they’re still on location. I believe they would just discard it with no directions, so what can I do once they get here? Where should I tell them to put the nest?

I’m really upset and hoping someone can tell me if there is anything I can do.
I recently moved into a new apartment in western NY, and since then there has been a bird nest on top of my window (picture 1).
Today, contractors came to replace the gutters  throughout the property. When I came home, the nest was completely gone.
Since then, the mother bird has been repeatedly returning with a beak full of worms, searching for the nest and clearly trying to feed her chicks. It is absolutely heartbreaking to watch.
I went downstairs to look for the babies, but all I found was what I believe to be part of a broken egg (picture 4). The contractors had left several trash bags around the property, and I’m wondering if they may have thrown the nest and chicks away. By the time I tried to locate one of the workers (with no luck) and came back, the bags were gone.
In my country this would never happen. The workers would either leave the nest alone or contact someone who could move it safely, so I was completely shocked. Is this common practice here?
The mother is still returning with food and waiting nearby, and it’s been about 7 hours since.

My questions are:

Should I contact apartment management?
Is there anywhere else I should look for the chicks?
Is there anything else I can do to help?

Any advice would be greatly appreciated.
