A top-fill hummingbird feeder is provided having a nectar container with a liquid flow opening at a lower end and a removable cap at an upper end, a feeding basin positioned below the nectar 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 float valve includes a float having a frame with a buoyant member mounted thereon, the buoyant member being made of a closed-cell foam.

A poultry feeder/waterer with internal shields provides space efficient poultry feeding and watering by using both sides of a tubular feeder, while preventing poultry viewing each other across the feeder using shields. The poultry feeder/waterer includes a tubular main body for holding poultry feed or water and having holes formed on either side. The centers of the holes are at the same height and are spaced apart by a distance greater than their diameter in order to provide distance between birds accessing the poultry feed or water. The poultry feeder-waterer also includes a stand for raising and leveling the tubular main body above the ground, and a pair of internal shields within the tubular main body and extending along its length prevents the birds accessing the poultry feed or water through holes on opposite sides of the tubular main body from viewing each other.
