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 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 releasable attachment of the tubular body member of the feeder thereon enabling easy access to the interior of the feeder.
