I love when different kids of birds come to spend time in my yard. If you agree, you might also have a few bird feeders hanging around. Many people have strung up hummingbird feeders, as hummingbirds are such a timid, beautiful species that people love to look at.
However, if you do have a hummingbird feeder, it’s vitally important that you clean it on a regular basis. Failing to do so can actually be fatal for hummingbirds.

According to World of Hummingbirds, hummingbird cleaners should be cleaned every three days or so.
When a hummingbird feeder isn’t cleaned properly, mold and mildew can begin forming in the nectar. As you know, hummingbirds are extremely small creatures with extremely small organs. Even the smallest bit of food contamination can cause severe illness and even death in hummingbirds.

If you notice the nectar in your hummingbird feeder appears to be discolored, slimy, or just doesn’t look right, you should remove the feeder and clean it out immediately. Take apart all of the pieces of the feeder.
Pour out all of the nectar and rinse thoroughly with hot water. Use a tiny scrub brush to ensure all of the nectar is cleaned out. You can use a mild soap, but be sure there is no soap residue left after you’ve rinsed the feeder out.

Let the feeder dry, then reassemble it. You can now fill it with new nectar and rest assured that no hummingbirds will be harmed when they’re enjoying a snack in your yard. Be sure to pass this information along to anyone you know with a hummingbird feeder, so that were able to keep our hummingbird friends safe and healthy!
