Certain look-alike hummingbird pairs can be maddeningly difficult to distinguish, even for experienced birders.
With over 300 hummingbird species in the world, some so alike that even DNA analysis is required to tell them apart1, accurate identification can be an epic test for birders.
Luckily, researchers have been studying the field marks and behaviors that separate these confusing cousins. Their findings can help you sharpen your ID skills the next time one of these fascinating birds come into view.
With some hummingbird twins, the similarities are so extreme that even experienced eyes can’t reliably tell them apart based on looks alone. That’s when researchers turn to DNA analysis.
A hummingbird’s geographic range and preferred habitat provide vital context clues for identification. Some species are found only in specific states or regions, while others are wide-ranging migrants that travel long distances seasonally.
The key to accurate hummingbird identification is observing and considering multiple traits—size, plumage, behavior, vocalizations, location, and more. Don’t rely on just one characteristic.
Field guides and online resources can teach you the distinguishing features of each species in your region. Photos and range maps are invaluable tools.
