These guys are much quieter than they are capable of being, and I appreciate that immensely since their pen takes a good while to clean.
Our indoor bird area is in the basement, and with the concrete walls, those catbirds and cowbirds are so dang loud in addition to whoever else may be down there. Bird room is loud and hectic, and while I love the birdies, the environment makes it next to impossible for me to enjoy for very long.
