I live in an urban area, and normally the quail are fairly quiet. The other night one of the quail was crowing all night, which bothers the chicken, who then also crow.(yea, I need to get rid of the crowing chickens before I get in trouble!) So last night I was out late, and put the chicken in their coop after dark. I noticed that the apartment complex across the street had replaced the light with a really bright light which happens to shine right into the quail cages. I covered them up and they were quiet again. It's generally pretty bright out at night anyway due to all the city lights, but this was ridiculous!
