A passive hummingbird water feeder and a feeding method thereof. By setting up an air cavity pipe, a delivery pipe, and a water storage bladder, and based on the siphon principle, water is introduced from the container into the water storage bladder without power with water level maintained, allowing water filling directly from above the container. The design simulates the foraging habits of hummingbirds, and enables photographing of flowers and birds.

A hummingbird feeder includes an upper lid, reservoir, camera unit, base, and sealing lid. The upper lid is detachably connected to the reservoir, sealing rings are sleeved on the sealing lid, the sealing lid is detachably connected to the reservoir, outer walls of the sealing rings are connected to an inner wall of the reservoir, the upper lid is sleeved in the sealing lid and detachably connected to the reservoir, and after the upper lid is connected to the reservoir, a pressure of the upper lid on the sealing lid is not zero. Compared with the prior art, the present disclosure allows the pressure of the upper lid on the sealing lid to enable the sealing lid to press the reservoir tightly, ensuring full contact between the sealing rings and the reservoir, and effectively improving the sealing performance.

An insect infiltration protection apparatus for a bird feeder comprising a bushing and a reservoir. The reservoir has inner and outer rims with a dish-shaped body extending therebetween that has a bottom surface with the inner and outer rims projecting therefrom. The reservoir has a support surface defining a central through hole adjacent the inner rim, which frictionally engages the bushing such that the bushing supports the reservoir with the bottom surface of the dish-shaped body vertically below a peripheral edge of the outer rim. The bushing is made from a resilient material and has a central aperture dimensioned for a friction fit with a pole to support the reservoir on the pole at a height above the support surface with a liquid in the reservoir at a level below the inner and outer rims.

A bird feeder includes a feeding component and a first camera, where the feeding component is provided with a feeding zone. The first camera is provided at or beyond an edge of the feeding component and shoots from or beyond the edge of the feeding component towards the feeding zone, and captures first image data. The bird feeder designed in the present application attracts birds to perch and feed via the feeding component, while the first camera positioned at the edge or outside the feeding component captures images or videos of the bird feeding activities to address the difficulty in bird observation and shooting, which enables the recording of detailed feeding activities without disturbing the birds which are feeding, thereby providing more stable and comprehensive documentation of bird feeding activities. This facilitates observers' examination of bird feeding processes, demonstrating significant potential for widespread adoption and practical application value.

A heater for a hummingbird feeder includes a waterproof heating pad with an adhesive surface for attachment to the bottom of a hummingbird feeder, and a power supply system comprising a weather-resistant transformer and power cable. The power cable may be permanently attached to the heating pad or detachably connected via weather-resistant electrical connectors. The heating pad generates thermal energy to prevent nectar from freezing, allowing hummingbirds to feed in cold weather conditions. The compact, universal design fits any hummingbird feeder model and requires no tools for installation.
