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.

An installation for rearing animals includes an injector; a water inlet line and a gas inlet line arriving in the injector; a source of oxygen or a gas mixture including oxygen, capable of delivering oxygen into the gas line; and a water recirculation loop including: a water tank, at atmospheric pressure, to supply the injector with fresh water; a coil capable of receiving water charged with dissolved oxygen from the injector through a pump, wherein the coil creates a water/oxygen contact time; and an overflow valve, to have the water resulting from the coil passed in order to be able to direct the water entirely to the animals' watering or partially to the animals' watering and partially back to the water tank. A method for rearing animals includes boosting water with dissolved oxygen up to saturation for animals' watering.

Animal drinkers of an activation unit provided with two arms engaging respective valve pin in an axially oriented manner when pivoting an activator. This reduces wear and leads to a longer service life of the drinker valve. The respective arm can moreover have a channel through which the water exits the drinker valve and can be fed in a targeted manner to the activator to ensure that all of the water exiting the drinker valve makes its way into the water collection tray.

A fluid dispenser for use for birds and animals and for use to purify water for human consumption is described, the dispenser having a fluid container and a valve rod that move relative to each other to open and close valves to an inlet funnel at an upper end of the dispenser and to a fluid reservoir at a lower end of the dispenser.
