Abstract: Implementations described and claimed herein provide disposable containers for feeding animals and systems, methods, and apparatuses related thereto. In one implementation, an animal feeder for use in dispensing animal food to birds or other suitable animals includes one or more reservoirs having one or more walls that allow a user to create one or more openings in the walls. The one or more reservoirs may be set on a tray to orient each reservoir to allow birds or other suitable animals to feed from the openings in each reservoir. The reservoirs are disposable and replaceable to provide a re-useable system for feeding birds.

Abstract: An animal feeder for use in dispensing a feeding solution to birds or other suitable animals. This may be accomplished by providing an animal feeder having a reservoir containing a feeding solution. The reservoir has walls that do not have a pre-formed opening. The walls are made from a material being sufficiently pliable to allow a user to perforate the walls to form one or more openings in the walls. One or more reservoirs may be set on a tray to orient each reservoir to allow birds or other suitable animals to feed from the openings in each reservoir. The reservoirs are disposable and replaceable to provide a re-useable system for feeding birds.

Abstract: 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.

Abstract: A feeding apparatus for use in dispensing feed formula to hummingbirds or other animals. The apparatus comprises a reservoir containing a ready-to-consume and preservative free feed solution for birds. The walls of the reservoir are made of a metal layer and a paper or plastic layer to provide a barrier to light, oxygen, and flavor to maintain the feed solution in a substantially sealed environment.

Abstract: A feeding apparatus for use in dispensing feed formula to hummingbirds or other animals. This may be accomplished by providing a feeder having a reservoir for holding ready to consume and preservative free nectar formula for hummingbirds. The feeder may have an opening that is configured to couple to a dispensing member for delivering the formula to hummingbirds. The feeder may be adapted to be supported by a support holding device or to be free-standing for maintaining the feeder in an orientation for dispensing formula.

Abstract: A hummingbird feeding apparatus for use in providing feed formula to hummingbirds. This may be accomplished by providing a reservoir for holding ready to consume and preservative free nectar formula for hummingbirds. The reservoir may have an opening that is configured to couple to a dispensing member for delivering the formula to hummingbirds. The reservoir may have an attachment member on one end for placing the dispensing member in a hummingbird-accessible location.

Abstract: Described are chemical compositions comprising a fluorinated solvent and a nonionic, poly-fluoroalkyl, hydroxy-substituted surfactant.
