Hummingbirds are nature’s living jewels, and witnessing their special displays is something many bird enthusiasts cherish. While these tiny flyers regularly visit our feeders, certain magical moments reveal their most extraordinary performances. Here are the telltale signs you’re about to witness something truly special in your backyard.
1. Male Hummingbirds Gathering in Groups
When multiple male hummingbirds gather in close proximity, prepare for something remarkable. According to Cornell Lab of Ornithology, males sometimes congregate during breeding season in “leks” – special display grounds where they compete for female attention. These rare gatherings often precede spectacular aerial performances. Males position themselves on strategic branches, temporarily tolerating each other before competitive displays begin.

Research from the Hummingbird Society shows that one of the most dramatic courtship displays is the dive display. Males fly up to 50-150 feet before plummeting in a distinctive U-shaped pattern. If you notice a hummingbird repeatedly climbing high only to dive steeply, you’re witnessing courtship behavior. The male pulls up sharply at the dive’s bottom, often directly in front of a perched female, creating distinctive sounds with his tail feathers.
3. Unusual Buzzing or Whistling Sounds
During special displays, hummingbirds produce distinct sounds unlike their normal wing buzz. Audubon Society research confirms many species create unique whistling or buzzing sounds during courtship, produced not vocally but by air rushing through modified tail or wing feathers. Anna’s Hummingbirds produce a distinctive explosive “chirp” at their dive’s bottom, while Broad-tailed Hummingbirds create high-pitched trilling during display flights.
4. Gorget Flashing in Sunlight
When a male hummingbird positions himself to catch sunlight perfectly, making his throat feathers (gorget) flash between dull and brilliant iridescence, he’s preparing for a display. Scientific studies show these specialized feathers contain microscopic platelets that reflect light like tiny prisms. Hummingbirds understand light angles and deliberately position themselves to maximize their plumage’s visual impact. Repeated gorget flashing signals he’s advertising his quality as a potential mate.
5. Shuttle Displays Between Perches
The Cornell Lab of Ornithology documents that some hummingbird species perform “shuttle displays,” flying rapidly back and forth in front of perched females like aerial pendulums. During these displays, males hover with their bodies nearly vertical, showing off their gorgets while spreading tail feathers wide. Rufous Hummingbirds are especially known for these dramatic side-to-side flights that demonstrate precision flying abilities and stamina.
6. Aerial Combat and Territory Defense
Research published in The Royal Society shows that spectacular aerial dogfights between male hummingbirds often accompany courtship displays as they compete for territory. These confrontations involve chasing at incredible speeds, sometimes even locking bills mid-air. Their combat skills include flying upside down, backward, and making instantaneous directional changes. These battles demonstrate flying prowess and dominance—qualities that female hummingbirds find attractive.

7. Hovering With Spread Tail Feathers
According to National Wildlife Federation, when a male hovers with tail feathers dramatically fanned out, he’s performing a courtship display. Different species have distinctive patterns—some fan their tails into perfect semicircles, while others display specialized elongated feathers. Broad-tailed Hummingbirds hover with rusty-red tails fully expanded against emerald-green bodies. This behavior is almost exclusively associated with courtship and rarely seen during feeding.
8. Pendulum or Swing Displays
Smithsonian research shows some hummingbird species, particularly in the Calliope family, perform spectacular pendulum displays like aerial swings. Males fly in wide arcs, tracing U-shaped paths in front of perched females, often covering 10-15 feet each direction. They maintain consistent height and distance, showcasing flying precision. The Calliope Hummingbird, North America’s smallest, adds vertical dives at each pendulum swing end, creating an even more complex aerial performance.
9. Presence of a Perched Female Observer
According to Behavioral Ecology research, one clear sign of imminent displays is a female hummingbird perched quietly, observing her surroundings. Males perform their most elaborate displays when females are present as audience members. Females typically find comfortable perches with good visibility and remain there for extended periods, evaluating multiple males’ performances. Though appearing disinterested, they’re carefully assessing each suitor’s displays for indicators of genetic quality.
10. Helicopter Hovering Displays
Research in the Proceedings of the National Academy of Sciences documents “helicopter displays,” where males hover directly above perched females in stationary positions. During this impressive feat, they maintain perfect hovers while facing downward, gorgets fully flared to maximize iridescence. This display requires extraordinary control and stamina, hovering in place for up to 10 seconds. Anna’s Hummingbirds combine this with gorget flashing to create dazzling overhead light shows.
11. Dawn or Dusk Timing
Animal Behaviour studies show increased hummingbird display activity during golden hours of early morning or late afternoon. Many species perform elaborate displays during these times when low-angle sunlight maximizes their iridescent plumage’s visual impact. The first hour after sunrise and last hour before sunset provide optimal lighting for gorget flashing. These periods also have calmer air conditions, allowing more precise aerial maneuvers and better sound propagation for wing-generated displays.
12. Seasonal Timing During Breeding Season
The U.S. Forest Service confirms spectacular displays coincide with breeding seasons, varying by region and species. In southern states, breeding displays begin as early as December for Anna’s Hummingbirds, while northern species like Ruby-throated Hummingbirds typically display from April through June. Increased territorial behavior during these periods indicates display season has begun. Peak breeding season features the most elaborate displays as competition intensifies.
13. Specific Perching Locations
Studies in The Auk (American Ornithological Society) show male hummingbirds establish favorite display perches they repeatedly return to during breeding season. These aren’t random choices—they select locations with good visibility, proper sun exposure for gorget flashing, and strategic positioning for dive displays. Males returning to the same exposed branch or wire are likely using it as a display perch. They defend these special locations vigorously, selected specifically for display advantages and territorial oversight.
14. Repeated Vertical Climbs
Research from Nature journal documents that hummingbirds making repeated vertical climbs straight up are likely beginning special displays. These ascents often precede dramatic dives, with males climbing 50-150 feet before plummeting. Rufous Hummingbirds sometimes ascend more than 200 feet before starting dive displays. These impressive climbs showcase strength and stamina, as vertical flight requires significantly more energy than horizontal movement—a powerful demonstration of fitness for potential mates.
15. Distinctive Face-to-Face Hovering
According to The Hummingbird Society, an intimate display involves males hovering directly in front of perched females, maintaining face-to-face positions just inches away. During this close-range display, males fully extend gorget feathers while rapidly moving their heads side to side. This behavior is especially common in Ruby-throated Hummingbirds, allowing females to inspect males’ coloration up close. Males maintain this challenging position for 5-10 seconds before retreating and potentially returning.
16. Dance-like Formation Flights
Research from The University of Chicago documents rare, spectacular displays involving choreographed flights between multiple birds. These synchronized aerial dances include competing males or, more rarely, male-female pairs flying in coordinated patterns during courtship. Birds mirror each other’s movements while performing loops, figure-eights, and spiral climbs. Costa’s Hummingbirds are known for these complex patterns, demonstrating not just individual skill but also the ability to anticipate another bird’s movements.
Keep your eyes open for these fascinating behaviors—they signal you’re about to witness one of nature’s most spectacular aerial performances!
