can this net be used to catch a parakeet that has escaped from its cage?
Martha D I would say yes. Even though this net is designed to catch butterflies, the netting material should be strong enough to catch a small bird if necessary. But not as a regular routine. Over time the bird's claws would undoubtedly start to rip through the mesh material if it struggles inside excessively. There are instead bird catching nets made for this specific purpose, if that is what you'd primarily be using this net for.
JUDITH J I think the opening of the net is too small for catching a parakeet. I always used a kitchen towel when mine got loose.
