Provided herein are bird feeders configured to be positioned on an exterior window sill ledge and readily observed and maintained from the comfort of a home. The bird feeders provided herein can in some embodiments comprise a basin or other container (and optional cover) for holding and/or providing bird seed and/or feed and a compression pad configured to be compressed between a closed window and the window sill to thereby secure the feeder in place on the exterior window sill ledge. In some embodiments adjustable support members can be provided to permit the feeder to be leveled or placed in a substantially level position on an exterior window sill ledge. To refill and/or maintain the feeder a user can access the feeder simply by opening the window from the inside of the home or dwelling.

A top-fill hummingbird feeder includes a liquid container with a liquid opening at a lower end. A feeding basin is positioned below the liquid container for containing nectar accessed by birds. A sealing mechanism includes a valve responsive to a nectar level in the feeding basin for opening and closing the liquid opening.

A hummingbird feeder device is disclosed that is an easier and more convenient way to feed and attract hummingbirds. The hummingbird feeder device comprises a housing component that is configured in a triangular-shaped elongated design with an open interior cavity. An internal bladder or pouch filled with nectar/hummingbird food is disclosed within the open interior cavity. The housing component comprises multiple removable sections on the triangular design, which are removed to access the pouch. Once removed, feeding plugs are pulled out from the pouch on all sides of the triangular design. The feeding plugs typically resemble a live flower with a hole in the center for access to the nectar from the pouch. When the feeding plugs are pulled out, nectar from the pouch is exposed, which will in turn attract and feed nearby hummingbirds.

A top-fill hummingbird feeder is provided having a liquid container with a liquid flow opening at a lower end and a removable cap at an upper end, a feeding basin positioned below the liquid container, and a valve or sealing mechanism associated with the liquid flow opening and the feeding basin. The feeding basin includes an upwardly extending cylindrical well that receives the lower end of the liquid container, and the valve or sealing mechanism includes a float valve associated with the well. The feeding basin is filled by gravity feed of the liquid in the container through the liquid flow opening when the sealing mechanism is open. When the feeding basin reaches a full position, the liquid nectar raises the float valve which, in turn, acts to close the liquid flow opening.

A top-fill hummingbird feeder is provided having a liquid container with a liquid flow opening at a lower end and a removable cap at an upper end, a feeding basin positioned below the liquid container, and a sealing mechanism associated with the liquid flow opening and the feeding basin. The sealing mechanism includes a bottle seal assembly configured for removable coupling with a base of the feeding basin, and a float valve captured by said bottle seal assembly to prevent rotation thereof while allowing the float valve to move upwardly and downwardly with changing nectar levels in the feeding basin. The feeding basin is filled by gravity feed of the liquid in the container through the liquid flow opening when the sealing mechanism is open. When the feeding basin reaches a full position, the liquid nectar raises the float valve which, in turn, acts to close the liquid flow opening.

A top-fill hummingbird feeder has a liquid container with a lower bottom opening which can be screw-threaded into a central collar of a feeding basin. An insert is received within the central collar and is configured to be vertically movable between a first position in which fluid is allowed to flow from the liquid container to the basin, and a second position in which fluid flow from the container to the basin is prevented.

A nutrient dispensing apparatus for birds having a hanger and two interchangeable dispensers supported by the hanger. Each dispenser includes a bottle for holding liquid or solid nutrients, and at least one basin into which the liquid or solid nutrients, water and bird feed, for example, are made available to the birds. The user can change the configuration of the dispensers as desired to provide just liquid nutrients, just solid nutrients or both. The flow rates for dispensing of the nutrients are different for each nutrient alternative.

An animal feeder for use in dispensing a feeding solution to hummingbirds or other animals. This may be accomplished by providing an animal feeder having a reservoir containing a feeding solution. The reservoir is connected to a dispenser that dispenses the feeding solution through an opening. The reservoir rotates in response to changes in the weight distribution of the feeder relative to the pivot as the reservoir is emptied of the feeding solution. The rotation of the reservoir maintains the opening in the dispensing member above the level of the feed solution in the reservoir. The reservoir has venting holes to maintain equalize pressure within the reservoir with the outside environment.

A liquid hummingbird feeder is provided with a liquid container having a sealable top opening and a bottom opening, a liquid tray adapted to immerse the bottom opening in liquid, and a valve mechanism adapted to close the bottom opening to enable the liquid container to be filled through the sealable top opening.

A liquid bird feeder provides a liquid container having a sealable top opening and a bottleneck extension at its other end, and a liquid tray having a well adapted to receive the bottleneck extension and at least one feeding port. The sidewall of the well is provided with at least one drain hole and the sidewall of the bottleneck extension with at least one port. The container and bottleneck extension are rotatable within the well to selectively align and misalign the port with the well drain hole to respectively open and close the drain hole upon rotation of the container. In an alternate embodiment, the bottleneck extension is fitted with a collar rotatable with the container. The collar is received in the liquid tray well and includes at least one port. A liquid flow path is formed in the liquid tray for each feeding port to reduce the volume of nectar in the tray at any given time.
