Abstract
An improved bird feeder includes a tubular main body having a top open end and a bottom open end. The tubular main body is made of wire mesh material. A bottom cap is attached to the bottom open end to enclose it. A tubular adapter sleeve is positioned in the top open end to protect and isolate the commonly sharp and dangerous top edge of the main body from the user. A top cap is removably positioned over the adapter sleeve to enclose the feeder to protect the feeder located therein. The adapter sleeve not only shields the user from a sharp and dangerous top edge of the mesh main body but also maintains the mesh main body in its original shape by avoiding flexing and bending of the mesh material of the main body.
