Follow these care tips to keep your hummingbirds and their feeders in prim shape:

  1. You must take precautions to prevent your nectar feeder from freezing if you live in a region that experiences harsh weather conditions.
  2. It’s best to avoid letting your hummingbirds consume really cold nectar as this could cause cold shock.
  3. Hummingbirds need to eat as early as possible, especially in the cold, to keep their energy levels up. Placing an incandescent light bulb close to it is recommended as these lamps emit enough heat to maintain the feeder’s temperature.
  4. The feeder needs to be cleaned and emptied twice weekly during the summer and once in the fall and winter.
  5. Additionally, you should clean the feeder every time it is empty if your hummingbirds frequent it. You can clean it with hot tap water or a mild vinegar solution. Dish soaps should not be used as they may leave dangerous residue behind.
  6. It is preferable to set out the feeder approximately a week before the hummingbirds generally arrive in your yard in the majority of North American regions.
  7. Even if the nectar is not consumed, maintaining the feeders’ cleanliness is still necessary.
  8. Never leave any nectar in the feeder that hasn’t been utilized when you take it down for cleaning.

Hummingbirds are a cute addition to any garden or landscape and it’s quite simple to draw them in. They are little, brazen, and jewel-like which is pretty eye-catching. In order to fuel their travels from breeding grounds in the Pacific Northwest to wintering grounds in central Mexico, they must double their body weight. Therefore, filling your bird feeder with sugar water is recommended.

To prepare hummingbird nectar, you can use tap water. Remember that any extra sugar water can be kept in the refrigerator for up to a week. However, it is best to make a fresh batch if you notice any mold growing on the one you kept away. Also keep in mind to never use honey, brown sugar, or any other sweetener as they are not healthy for hummingbirds.

This is because brown sugar, like others, has too much iron. A sugar water solution is more difficult for these birds to digest if it is sweeter than the 4-to-1 ratio mentioned in this article. Even for these feathered creatures, there is such a thing as too much sweetness.
