Abstract: A bird feeder with a tubular body member having a sidewall and an open top end includes a top cap member that engages the top end of the tubular body and also has a means for releasably securing the top cap to the tubular body. The top cap is releasably secured to the tubular body by the engagement of a lock slot that communicates with a lock protrusion on the sidewall. A spring member biases the top cap away from the tubular body to keep the lock protrusions seated in the lock slots. Preferably, there are two lock slots on opposing sides of the top cap with corresponding lock protrusions on the tubular body. The top cap is depressed to overcome the resilient spring member to unseat the lock protrusions to permit releasable attachment of the tubular body of the feeder thereon enabling easy access to the interior of the feeder.

Abstract: A bird feeder has a tubular body member having an open bottom end. A base member interfittingly engages the bottom end of the tubular body member and also has a means for releasably securing the base member to the tubular body member. The base member is releasably secured to the tubular body member by the engagement of a spring-biased pin that communicates with an aperture through the wall of the tubular body member. Preferably, there are two spring-biased locking pins on opposing sides of the feeder with corresponding lock eye apertures. User manipulatable buttons, which are mechanically linked to the locking pins, are depressed to cause the locking pins to retract to permit releasble attachment of the tubular body member of the feeder thereon enabling easy access to the interior of the feeder.
