Can hummingbirds smell sugar water? Take a look at this article and found out the real truth.
There are so many fascinating facts about these unusual tiny creatures. They are excellent avians, even better hiders than predators, and are widely known for their extremely fast metabolisms, which require them to eat all day long just to survive. Did you know that on average these birds visit between 1,000-2,000 flowers during the day? So small, yet so voracious, right?
However, how do they even find a feeder? What senses lead them to food, more specifically, can hummingbirds smell sugar water? Stay here to learn a thing or two about one of the most beloved backyard visitors.
What’s The Deal With The Nose, Do Hummingbirds Have A Sense Of Smell?
In order to find out the answer to the question “can hummingbirds smell sugar water”, it is necessary to say a few sentences about their, above all, unusual anatomy. Accordingly, we have found research that finally dispels the centuries-old myth that hummingbirds don’t have an active sense of smell.
Some species of birds have an excellent sense of smell thanks to their large olfactory bulbs. Namely, it is a rounded mass of tissue that contains several types of nerve cells directly involved in the sense of smell. When a bird breathes, these bulbs receive information about smells and send it to the brain by way of the olfactory tracts.
As for the heroes of this article, tiny hummingbirds, their nostrils are located at the base of the bill, at the place where air enters their lungs. However, it is important to emphasize that their olfactory bulbs are extremely small. If you want to compare them with other flying creatures for easier understanding, their bulbs are about half that of seabirds and slightly less than that of Rock Pigeons. Be that as it may, try to remember that hummingbirds undoubtedly have an active sense of smell.
To be honest, it’s pretty easy to understand why it’s been widely believed that these birds have no sense of smell. There was no technology that could clearly show whether hummers had a preference for the scent of nectar-containing flowers. In addition, first-hand experience clearly shows that bird-pollinated flowers generally don’t have strong fragrances, unlike those pollinated by insects. This is the main reason why scientists were firmly convinced that these unique creatures don’t have the ability to smell things.
Some More Research Results
We assume that you came here because you have an insatiable hunger for new information and fun facts, so we decided to dedicate a few sentences to one of the most interesting abilities of these birds. Namely, did you know that hummers can smell their way out of danger?
Scientists from one of the most famous universities in the world, Riverside, California, discovered that these amazing creatures can not only smell insects, but that sense of smell can help them avoid danger while hunting for nectar. Is it even necessary to emphasize that this is a life-saving feature?
Now that we have learned some basics, we can finally find out the answer to the question “can hummingbirds smell sugar water”. So let’s go into details.

Two of which were filled with their favorite, sugary water, and the remaining two with a 3% saline solution. Two feeders also contained ethyl butyrate. This solution had a characteristic smell of chewing gum.
Do you know what happened? 60% of the birds chose the feeder that was filled with both ethyl butyrate and sugar solution, instead of the feeder that contained the scentless saline solution.
