Claims
Birds are social and can get lonely if they don’t get enough attention.If they're not stimulated enough, they can develop behavior problems like biting, screaming, or pulling out their feathers.Boredom is a big reason for these unwanted behaviors, so it's important to provide ways for birds to stay active and interested.To keep your bird entertained, you can play music or leave a TV on nearby.Regularly spending time with your bird, especially for training, helps keep them happy.Small cages can stress birds out and lead to problems.Most birds shouldn't have their cages covered at night, because that can stress them out.Avoid mirror toys that might confuse birds and stress them out.
