I have a lovely parakeet and a friend advised that I have his wings clipped. I'm unsure and would appreciate the views of others to help me decide what to do, thanks.

Unless you have birds in a flight cage, or aviary, I feel it's a good idea to keep the bird's wings clipped. It's not cruel and doesn't hurt them at all. The feathers do grow back, so you will have to do it more than once, obviously. It's much safer for pet bird's that are kept indoors to be clipped. Birds that can fly around the house can get into all kinds of trouble. Flying into a fan, window, boiling pot of water, or even just onto a hot stove can be deadly.

Do not, however, clip your own bird's wings unless you know what you are doing. I know a visit to the vet cost's more than your little parakeet, but it's well worth it to take the bird in to the vet and have your vet show you how to clip the bird's wings. Only the primary flight feathers should be clipped, never the coverts. The primaries are the longer 10 wing feathers from the tip of the bird's wing in. The coverts are the small feathers that overlap those on the top of the wing. The secondary flights are the rest of the wing feathers between the primaries and the bird's body. You also need to be very careful not to cut a "bloodfeather". A bloodfeather being cut can act as a syphon causing your bird to bleed. Bird blood does not clot quickly as humans does, which could cause your bird to bleed to death. Also, the smaller the bird, the faster the heart will pump blood out. Flour can be used as a clotting agent as well as styptic agents, but flour is the safest. Alsways air on the side of caution and let someone that knows what they are doing either clip wings for you or show you the proper way to do it. This will help keep your bird grounded
