Tip 1: Observe The Size Of The Bird

Male Vs Female Size Differences

Identifying the sex of ruby-throated hummingbirds can be quite challenging, but knowing their size differences can make the job much easier. Male and female ruby-throated hummingbirds differ in their physical attributes. Here are the differences in size between the two sexes:

  • Adult female birds usually measure between 7 to 8.5 cm from bill tip to tail. Whereas male birds measure between 7 to 9 cm.
  • The male birds typically weigh 3.1g, whereas females average around 3.4g.
  • Female birds have a slightly larger wingspan ranging from 8.5 to 11 cm, compared to males with a smaller wingspan of around 8.5 to 10.5 cm.

How To Take Accurate Size Measurements

If you want to take accurate size measurements of ruby throated hummingbirds, then it is recommended to follow these guidelines:

  • Always use a caliper or a ruler with millimeter markings to measure the size of the bird.
  • Gently catch the bird in your hand and measure it quickly to avoid causing unnecessary stress.
  • When taking measurements, make sure to stretch the bird’s wings to their full length but be gentle because hummingbirds have delicate bones that can easily break.
  • If you cannot catch the bird, try to observe its overall size compared to other hummingbirds in its vicinity to get a rough idea of its sex.

Knowing the size difference between male and female ruby-throated hummingbirds can help you identify their sex, but it is important to approach these delicate birds with care and caution.

Tip 2: Analyze Feather Coloration

Differences In Male And Female Plumage Colors

Ruby thumb birds are predominantly green, and both male and female birds have a green mantle. However, the male bird is generally more colorful than the female. Here are the distinctive differences in plumage colors that can help identify male and female ruby thumb birds.

  • Male ruby thumb birds have vibrant, bright green feathers with a touch of yellow. The tail feathers are black with violet-blue tips and purple or blue iridescent dots throughout the plumage. The head, neck, and chest have a red, violet, and purplish sheen.
  • On the other hand, female ruby thumb birds have muted green feathers with a hint of olive or blue. The tail feathers are green with a greyish-brown base, and the outer feathers often have narrow white tips on the ends. The head, neck, and chest feathers do not have any noticeable sheen.

When To Pay Attention To The Coloration

Identifying the ruby thumb bird’s plumage colors can be tricky, but it is an essential factor in distinguishing male and female birds. Here are some tips on when to pay close attention to the bird’s coloration.

  • Males and females show distinctive plumage colors in adulthood. However, juvenile ruby thumb birds have subdued and dull feather colors, making it challenging to differentiate male and female birds.
  • During the breeding season, males’ plumage colors become more vibrant as a part of their courtship ritual. Females tend to have less pronounced color during the breeding season.
  • Color changes in feathers occur with age, so it is crucial to keep observing the birds to determine their gender properly.

Differences In The Size, Shape, And Curvature Of The Beak

The beak is an important feature that can help you distinguish between male and female ruby thumb birds. Here are the key things to look out for:

  • Size: In general, male birds tend to have larger beaks than females. If you spot a bird with a particularly large beak in relation to its body, it’s likely to be a male.
  • Shape: The shape of the beak can also vary between males and females. Male birds tend to have squarish or blunt beaks, while females have narrower, more pointed beaks.
  • Curvature: Look at the curvature of the beak to help you identify the gender. Males often have a more pronounced curve than females, which can help them to sing more loudly and attract mates.

Why The Beak Shape Is Important In Identification

The shape of a ruby thumb bird’s beak can provide important clues about its gender. Here’s why:

  • Sexual dimorphism: Like many bird species, male and female ruby thumb birds are physically different from one another in a number of ways. The size and shape of the beak is one of the most easily visible differences between the two sexes.
  • Adaptations for survival: The shape of the beak can also reflect the bird’s diet and habitat. Ruby thumb birds have evolved different beak shapes to help them feed on different types of food, such as nectar, insects, and fruit. By studying the beak shape, you can better understand what the bird is likely to eat and where it is likely to live.

By paying close attention to the size, shape, and curvature of a ruby thumb bird’s beak, you’ll be able to identify its gender and learn more about its habits and habitat.

Tip 5: Observe The Head Shape And Coloration

Ruby-throated birds are one of the most eye-catching and lovely birds to observe. If you’re lucky enough to see one, you might wonder whether it’s a male or female. Fortunately, distinguishing between male and female ruby-throated birds is possible, and we’ll discuss ten tips to help you identify one.

In this section, we’ll focus on tip 5: observe the head shape and coloration.

Differences In The Shape And Color Of The Head

The head’s appearance is critical when determining whether a ruby-throated bird is male or female. The top of both sexes’ heads is green, but the overall shape of the head varies slightly between males and females. Males have a slightly rounder head shape, whereas females’ heads are typically flatter.

Additionally, the coloration of the head can differ between males and females. Males often have a more vivid red throat compared to females. Moreover, when looking at the bird’s crown, males typically have a bright, deep red patch, whereas females have a subtle, pale red patch.

If you cannot see the bird’s throat, you can also tell the difference between the sexes based on their facial feathers. On males, the feathers around the bill are black and extend further back than the female’s bill feathers.

Conversely, the female’s feathers around the bill are usually light grey, and this color doesn’t extend back to the eye area.

Observing the head shape and coloration is essential in distinguishing between male and female ruby-throated birds. So next time you spot a ruby-throated bird, take a closer look at their head, and you might be able to tell whether it’s a male or female.

Tip 6: Look Closely At The Tail Shape

Differences In Male And Female Tail Feather Shape And Length

One of the most effective ways to identify a ruby thumb bird’s gender is by examining its tail shape and feather length. There are distinct features of the tail that vary between males and females:

  • Males have longer tails and larger feathers, enhancing their beauty and enabling them to perform aerial acrobatics better.
  • Conversely, females have shorter tails that are relatively small and exhibit a rounded shape.

Ways To Measure The Tail Length

Furthermore, measuring the bird’s tail length can lend us further clues to help us identify its gender. Here are some ways to measure the tail length of a ruby thumb bird:

  • Capture the bird without causing harm and stretch its tail feathers gently without breaking them. Measure the length of the feathers with a ruler or a tape measure.
  • Watch the bird from a distance. Observe its flying and feeding patterns, which can help differentiate a male from a female. Males often demonstrate incredible flight maneuvers to attract females, while females’ movements focus on obtaining food and feeding their young.

Determining whether a ruby thumb bird is male or female is not challenging as long as you know where to look and what to observe. Careful attention to the tail’s length and shape can provide valuable insights into the bird’s gender.

Tip 7: Watch The Body Shape And Stance

Differences In Body Shape And Stance Between Male And Female Birds

When it comes to identifying the ruby-throated hummingbird’s gender, watching its body shape and stance is crucial. One way to do this is to observe their posture when they hover around a feeder or flower. Males and females have distinctively different body shapes and stances, making it easy to identify them.

Here are some notable differences in body shape and stance between male and female ruby-throated hummingbirds:

  • Male ruby-throated hummingbirds have a more streamlined body shape with a straighter profile. They have a shorter tail and a wide, square-ended r1 feather, which is usually longer than their tail feathers. This gives them a tapered look with a compact appearance.
  • Female ruby-throated hummingbirds have a more rounded body shape with a slightly curved profile. They have a more extended tail and a narrow, pointed r1 feather that is shorter than their tail feathers. This gives them a bulkier look with a less streamlined appearance.

How To Take Note Of The Body Shape and Stance

Identifying a ruby-throated hummingbird’s gender based on their body shape and stance requires some patience and keen observation skills. Here are some tips to consider:

  • Take note of their hovering position: Male ruby-throated hummingbirds tend to hover in place with their body horizontal to the ground, while females hover at a slight downward angle with their tail cocked downward.
  • Observe their posture while perching: Male ruby-throated hummingbirds sit up straight, their wings held close to their body and their tail feathers pointing slightly upward. In contrast, female ruby-throated hummingbirds perch with a crouched posture, with their wings and feathers held tightly against their bodies.
  • Look for a visible neckband: Male ruby-throated hummingbirds have a bright red gorget on their throat, which is absent in female birds. This feature is the most apparent difference between the two genders and can help typify the bird’s gender.

Overall, examining the body shape and stance of ruby-throated hummingbirds is essential in identifying their gender. By paying attention to the notable differences between male and female birds, you can hone your observational skills and quickly determine the bird’s sex.
