Thank you for your response. I was still not sure. I called the avian vet at Texas A&M, and they told me, NO it was not safe for birds. It is because it has poly glycol__something, ether, and butane. If the birds could be removed from the house for at least 3 days, then it would be ok, but since it takes about 3 days for the acid to cycle through the coils and eat away all the goop, it is better for them to be removed from the house.
That wasn't an option for me. So I ended up going ahead with the $250. pull and clean the coil job. Thaty's still cheaper than killing 2 birds that cost over 2000.00. I love my babies.
BUT it is safe for humans. Go figure.
That's why they used canaries in coal mines.
