Bathroom Vent Fan

The ventilation fan directly outside my house and we have heard the chirping this weekend, I did not really want to open the fan in the bathroom, if I can help (then I'm having birds in my house in a Vice fan) but I know I need to get out before I close the hole with thread.

Wait until the birds get big enough to leave themselves a few weeks. Then remove the nest and close the thread.

The rescue is good, but after he went, just put some screen around the fireplace and more birds.

I agree with the way the group of birds go resuce. Please do not harm birds. :)

Run the fan drive them away?

If there are no young chicks / chicks in the nest, try to blow cigar smoke through it.

Otherwise, look for the nearest group of bird rescue and see if they can send someone over to try to capture the bird and remove the nest to their care facility.
