Do Hummingbirds Recognize Humans?

Do hummingbirds recognize humans

What does it mean when a hummingbird looks at me? – Scientists believe that the ability to distinguish different shapes and patterns comes naturally due to hummingbirds’ evolutionary history. Like parrots, hummingbirds belong to order Psittaciformes, a group that encompasses every type of living and extinct member of the family Psittacidae.

That said, there aren’t any extant members of the order Psittaciformes that live exclusively on insects, fruits and tree sap, either. Most psittacs eat nectar and pollen, although cuckoo pocks, guineas and turkeys consume invertebrates like earthworms and snails.

Not surprisingly, then, hummingbirds must be able to discern not only shape, pattern and texture, but also chemical composition. For instance, nectar tastes sweeter depending upon where it came from, and certain types of flowers produce chemicals that differ from others.

Can hummingbirds recognize humans?

So, Do hummingbirds recognize humans? The answer is yes, Hummingbirds can remember people and will fly overhead to remind them of empty feeders or tainted sugar water.

Hummingbirds are extremely intelligent. Hummingbirds, on the other hand, have brains that are more than double the size of the ordinary human.

Every flower or feeder they visit, and how long it takes for a plant to resupply nectar once it runs out of nectar, are all affected by this mental capacity. A creature with a heart rate of 1200 beats per minute cannot waste the same amount of energy as an empty refrigerator.

Though hummingbirds lack specialised cognitive faculties such as face recognition and speech comprehension, experts believe that they rely heavily upon instinctual behaviors to survive. Previous studies have suggested that hummingbirds navigate unfamiliar areas based on landmarks, relying upon innate navigation skills honed throughout thousands of years of evolution.

The Role Of Sense Perception

We already mentioned that hummingbirds might not require seeing capabilities to find food sources. However, researchers have suggested this doesn’t mean hummingbirds rely solely on smell and taste, which would make them very picky eaters indeed. For example, some research indicates that hummingbirds can detect the presence of certain chemicals produced by plants — specifically terpenes and monoterpenoids, compounds found in citrus oils and other essential oils.

Terpene molecules also emit particular types of smells similar to those emitted by male insects, so perhaps female hummingbirds use scent cues to help them choose mates. What we don’t yet understand is whether hummingbirds can pinpoint specific locations based on chemical signatures emanating from plant life around them.

Another study demonstrated that black-capped chickadee chicks were able to learn where hidden seeds lay after watching older siblings gather up food for themselves. Chicks who watched older siblings scooping up corn kernels learned faster and performed better than did chicks who didn’t observe others gathering food. Researchers concluded that learning takes place via imitation, with juveniles mimicking adult behavior. If you’ve got your own backyard garden, try observing hummingbird activity in your yard next time you go outside. You’ll likely get a kick out of the experience!

In addition to olfactory clues, another way hummingbirds may determine where to focus their attention is by sensing subtle changes in sound. Research published in 2008 showed that Anna’s hummingbirds pay close attention to sounds around them. These birds were observed pecking away consistently at areas surrounding open patches within flowering shrubs.

Scientists believe that hummingbirds respond to minute fluctuations in air pressure caused by nearby objects moving across the ground. When hummingbirds detected movement, they often landed within 1 meter (3 feet) of the object causing the disturbance. Interestingly enough, Anna’s hummingbirds don’t seem too keen on artificial noise either. A 2006 study conducted by researchers at Cornell University determined that New York City-area hummingbirds show no preference for songs played over background noises.

Of course, none of these findings necessarily imply any sort of visual recognition skills. But since hummingbirds are known to spend much of their lives hovering above blooming flowers looking for sugary treats, it stands to reason that our feathered friends might possess some type of visual perception capability.

One final consideration is the possibility that hummingbirds simply prefer to land near places containing abundant amounts of nectar. After all, the sweet stuff does contain lots more energy per gram than ordinary drinking water. Nectar typically contains 10 percent glucose, 40 percent fructose and 50 percent sucrose. As far as nutrition goes, it’s not exactly high in protein or vitamins, but hey, it tastes good!
Now that we’ve discussed the role of sense perception, let’s consider the evidence supporting the idea that hummingbirds perceive humans. On the following page, we’ll examine some theories suggesting hummingbirds can discriminate between members of their own species.

Hummingbird Recognition Theory

Can hummingbirds really differentiate among different people? That seems unlikely given how small their brains and eyes are, but scientists continue to investigate the topic. Several years ago, ornithologist David Steen examined hummingbird flight patterns using computer simulations and mathematical modeling techniques. He then took measurements of actual hummingbird wingspan and body size and compared the results with data gathered from video recordings of hummingbird flights. To Steen’s surprise, several aspects of the simulated hummingbird flaps matched real-life observations made under controlled conditions.

Steen’s work isn’t the only recent indication that hummingbirds can discern between members of their own kind. In 2007, biologist Edward Oakes noted that captive African starlings living together displayed distinct territorial boundaries. Birds kept apart by wire mesh fences flew along separate paths until they met again later downrange; stars that lived together were less likely to reunite than pairs belonging to mixed groups.

Oakes thought these differences indicated that starlings recognized each other visually. Subsequent experiments confirmed that this was probably true. Starlings housed individually in adjacent cages avoided contact with each other except when forced into physical proximity, whereas pairings formed easily.

If hummingbirds possess the capacity to spot fellow hummingbirds, why haven’t we witnessed any instances of aggression involving birds of various sizes and colors? Perhaps smaller hummingbirds tend to avoid larger ones due to competition for resources. Or maybe large hummingbirds fly higher than medium-sized counterparts, making them harder to spy. We won’t know for sure unless someone conducts extensive observation sessions over extended periods of time. Until then, we must remain agnostic on the matter.

With all of this talk of hummingbirds, it’s easy to forget that they don’t enjoy eating fruit exclusively. Black-throated blue warblers (or Dendroica caerulescens), for instance, feast on tree sap called phloem, which delivers nutrients throughout a plant’s system. Blue martins also consume nectar and pollen found inside bee hives.
