how to get rid of crows nesting on our room

There is a gel available. It can be spread over the area of interest
attracting your crows. As they land on the gel, it gives a burning
sensation to their claws. They will soon tire of the landing pad.

This is on a recess of our roof (25 feet up).  The mother had two
babies up there.  What kind of gel and I'm not sure who would be brave
enough to get up there to spread the gel.

Here is some help:

Close your windows if they are ?nesting on our room?.

Guess you meant ?roof?. Plant some trees and wait 50 years. Crows
usually prefer tall trees to roofs. The 500 rooks above the end of my
garden never bother us.

Seriously though, your problem may be caused by ecological imbalance
whereby natural avian predators are depleted so nesting takes place in
open areas, but there is a surfeit of readily available food for
opportunist feeders.

I guess this doesn't help, but there is an action plan there.

(It's ROOF - not room) We have found the food source to be an open
garbage dumpster from a nearby apartment complex.  This has been
reported to the city.  In the meantime, the crows have planted a dead
squirrel in a tree (in front of our home--hello) I guess for future
feeding.  HELP!

An owl decoy will do the trick. There are many diferent kinds of owl
decoys - some are animated and make noise, some do not. They come in
various price ranges too and you just place them where the pests
congregate and that's it.

"An owl effigy will only work for a few days and chances are you will
actually hear more noise as the crows try to drive the owl away. They
will soon learn that the owl is fake after a few days. To reduce this
risk, be sure to move the owl around or get one that moves and hoots.
