Like most birds in the wild, male hummingbirds wear the bright colors and the females are dull and drab, making them easy to distinguish. According to the Scientific American website, Charles Darwin believed the bright colors of the males help attract favorable mates. The theory that females believe bright colors indicate health and vitality may provide backup for this theory. However, other theories state that the female birds are more susceptible to prey animals when nesting and bland colors help them to blend in with the environment.
These breeds of hummingbirds are named for their unique colored throats. The male ruby-throated hummingbird has a glowing, bright red throat. The blue-throated male has a dark blue colored throat that appears black in dim light. The female ruby- and blue-throated hummingbird is fairly colorless.

A shuttle display demonstrates playful, attentive and seductive attributes of affection to win the hand of a fair maiden.
He also adds a vocal whistling to help seal the deal. If a perched female is watching and is interested, she may join him in this dance of affection. Hummingbirds do not mate for life. The male hummingbird leaves almost as quickly as he arrives. All hummingbird females are single moms and male hummingbirds are polygamous.
Once their mating is done, the males leave the females to incubate the eggs and raise the young on her own. If you come across a hummingbird nest and see an adult nearby, it will be a female. If you see a busy hummingbird flying religiously back and forth to a particular location, jumping up and down on a perch, acting strangely and carrying materials in her bill, there is a high probability you are witnessing a female building her nest!
Likewise, if a hummingbird is attentively brooding for long periods of time during the day in the nest, caring for hatchlings and actively foraging for food and returning to the nest, then it is safe to conclude that you are witnessing a mother hummingbird. In the hummingbird world, the female does all of the nest preparation and child-rearing. Once the female is impregnated by the male the countdown of time begins for her to build her nest.
Eggs are growing inside of her while she determines the perfect location to build a nest while frantically gathers nesting materials. The female will locate a nesting territory with high standards which include the perfect protected location from all types of unstable weather such as rain, wind and temperatures.
She strategically locates camouflaging nesting materials such as moss, lichen and other small twigs to construct her nest.
These masterfully designed cup-like nests are glued together with spider silk. As the young hummingbirds grow, their mother will often repair the nest if it starts to grow weak from their rapid growth. The females put an extraordinary amount of work into their nests since their babies need to stay snug and safe in it for weeks. Food abundance is crucial near a nest.
When it comes to mating and raising young, it is a major priority to be able to keep themselves and their offspring fed. As mentioned earlier, male juvenile hummingbirds during their first year of life, will closely resemble their mothers. It is easy to mistake a juvenile male hummingbird for an adult female if they are out of the nest and in flight. However, there are a few differences that might give a hint as to their gender.
Male juveniles are smaller than their mothers. Before they come into their adult plumage, the most telling sign of a juvenile is a pattern of dark streaks on the throat as they begin showing signs of their colorful gorgets.
Females like male juveniles, resemble their mother and are identified with plain white throats and dull coloring. As males become colorful, females on the other hand will continue to keep their muted tones. Identifying hummingbird gender is fairly simple by observing a few physical characteristics. First, check out their color and size as the most obvious clues. Second, rely on their sounds and behavior. Likewise, if you spot a more subdued colored hummingbird with spider web silk or small twigs in her beak, you can bet this one is a female mother expecting and is preparing a sturdy nest to raise her young.
If you hear a vibrant and non stopping chatter, it is a male defending his territory with preliminary warnings. A female is just as fierce when protecting her young, but is less vocal and more aggressive with less warnings. During migration, males will leave up to three weeks earlier than females. If you see some hummingbirds lingering behind while others have started to migrate, they are the females. This size difference is because females lay eggs and their bodies need to be able to support this process, from actually laying the eggs to sitting upon them to keep them warm.
In mating situations, it is simple to tell a male and female hummingbird apart. Once a male hummingbird finds a female to mate with, he will do a series of dances to impress her. Sometimes females even join males in their dances. Males and females do not mate for life, and males play no role in caring for their offspring.
After mating, the female will build a nest and raise her offspring on her own. Females will chase away males that come too close to their nest, as the bright males attract predators. In general, male hummingbirds are much more aggressive than females. They need to be aggressive to attract females and to defend their territory.
