I have a male gloster canary. When he sings he sings up a storm. Sometimes I wish his song was a little different but he’s a great lil bird. I feed pellets and always water. Treats on occasion but early this spring he stopped singing and went into what I thought was a soft molt. His cage was was to close to a regularly used door It was also on top of the fridge ( resident feline). Up till then he was singing up a storm. How can I fill this house with his pretty song again. Or is he just molting and I have to wait for him. Insight? Suggestions. Thanks !!!!
