An Oriole bird feeder having a nectar reservoir with a base and a tapered port, and preferably a tapered port/perch assembly, is provided. The bird feeder allows Orioles and other similarly sized members of the Icterid family of birds to land on the perch and access the nectar in the reservoir base while, due to the diminishing taper of the opening in the tapered port, simultaneously preventing average sized Italian, Carniolan and Caucasian honey bees from entering the reservoir base through the port to obtain the nectar where they subsequently become trapped and perish.

Animal drinkers for beaked animals often have drinker valves (12) which are to be opened by activation units (13). In order for the respective drinker valve (12) to be opened, an elongate activation means (29) of the activation unit (13) is pivoted by the beaked animals. Conventional drinker valves of this type have above all the disadvantage that the respective valve pin (16) of the drinker valve (12) is always tilted in the same direction by the activation unit (13). This leads to unilateral wear and therefore to the respective drinker valve (12) being worn out in a rapid manner.

The invention provides that the activation means (29) of the activation unit (13) is provided with at least one arm (30, 31). On account of said arm (30, 31) the respective valve pin (16) is able to be lifted in an axially oriented manner when pivoting the activation means (29). This reduces wear and leads to a longer service life of the drinker valve (12). The respective arm (30, 31) can moreover have a channel (36) on account of which the water exiting the drinker valve (12) can be fed in a targeted manner to the activation means (29). It is ensured on account thereof that the all of the water exiting the drinker valve (12) makes its way into the water collection tray (14).

Provided herein is a portable coop that helps maintain hygiene within the living space. The portable coop has a lockable first entry door and a lockable second entry on either end of the coop which when opened respectively provide access for easy cleaning and easy access into and out of the coop for the poultry. The inside of the coop contains nesting box(es), feeder troughs and perch(es). Water and food reservoirs attached on the outer surface but open to the inside of the coop. Poultry can access water and food when needed from within the living space. The reservoirs keep the food and water free from mold and other infectious agents thereby helping maintain a heathy flock.

A nanobubble generator, a nanobubble-containing liquid solution comprising a substantially high concentration of nanobubbles, a system and methods of producing the nanobubble-containing liquid solution. The nanobubble generator includes an inflow portion for receiving a source liquid solution, a series of at least two sequential cavitation zones and shear planes to treat the source liquid solution and producing nano-bubble containing liquid solution, and an outflow portion for releasing the nanobubble-containing liquid solution.

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.

A hummingbird and oriole feeder having a nectar reservoir that allows the beak of a feeding bird to access a nectar access point to the nectar. An optical sensor senses the bird's beak entering the nectar access point. The optical sensor can include an optical transmitter forming a beam of light that is received by an optical receiver. The intrusion of a bird's beak into the nectar access point, which occurs when the bird is feeding on the nectar, interrupts the beam of light, creating a change in an electrical signal. The electrical signal is sent to a processing unit that counts each time a bird's beak penetrates the nectar access point and displays the count on the display unit. The count can be reset to zero by a reset switch. There can be multiple nectar access points, which are each counted, using a multiplexer.

Animal watering stations having a liquid piping system including watering lines, a supply line, and a return line. The supply line supplying liquid simultaneous to all watering lines and the return line returning of liquid to a liquid reservoir. In this way, a circulation of the liquid can be realized in at least parts of the liquid piping system and on the other hand the parallel fluidic circuit of the watering lines enables an easy adapting of the liquid pressure at the drinking valves.

A water feeder filter water feeder includes a water storage tank and a water drinking portion. The filter supplies and returns water from the water storage tank to the water drinking portion. The filter is detachably provided between the water storage tank and the water drinking portion and passes the water from an upper surface side to a lower surface side of the filter. The filter includes a filter tray with a bottom wall having a water passing aperture and an outer peripheral wall. An internal filter medium is in the filter tray. A top covering filter medium covers an upper end opening of the filter tray. A partition wall of the filter tray is formed with a lower side is positioned inner than an upper side when viewed from each chamber. The outer peripheral wall is formed with a lower side is positioned inner than an upper side.
