A bird feeder includes a container and a lid. The container includes a body and a neck. The neck includes an opening and the outer surface of the neck includes a first thread. The lid is configured to engage the neck. The lid includes a top wall and a side wall bounding a peripheral edge of the top wall. An inner surface of the side wall includes a second thread that is configured to engage the first thread of the neck so as to close the lid onto the container. The top wall includes an opening and a perch is disposed on the lid. An attachment member is formed on an outer surface of the lid.

A fastener for securing a first object to a second object includes a push member, a rigid shaft, an engaging member, a biasing member, and an anchor. The push member and the anchor are fixed to opposite ends of the rigid shaft. The engaging member is slideably coupled to the rigid shaft between the push member and the anchor. The biasing member is disposed between the push member and the engaging member to urge the engaging member toward the anchor. In a particular embodiment, the anchor is deployable.

A platform bird feeder including a base platform with a seed tray, a baffle and a center pole having a bottom end connected the tray, the baffle being tiltably and adjustably mounted to the pole above the base. Preferably, the seed tray has a seed protecting grate to hinder squirrels from accessing the seed in the tray. The height of the baffle above the seed tray may be adjusted up and down to allow the user to increase and decrease the seed access space, respectively, between the baffle and the tray. When the baffle is at a desired height, it is secured in place by an adjustable securing mechanism that, while holding the baffle at the desired height, allows the baffle to tilt or wobble when sufficient weight is placed on one side of the baffle.

A feed hopper with two chute members is provided. The chutes are movable with respect to one another and one chute has an extending lip to engage the inner surface of the other chute to prevent feed from escaping the hopper.

A trough feeder system has a plurality of troughs connected with couplers to prevent the troughs from rotating relative to each other. Each coupler has at least one sidewall stop protruding inwardly from a sidewall that limits the distance the trough can be inserted into the coupler. The coupler has a central catch generally above the sidewall stop and a pair of outward catches, wherein the central catch and one of the outward catches capture each trough at different positions along the longitudinal axis of the trough so as to prevents the trough from rotating relative to the coupler and also the adjacent trough being held by the coupler.
