Some hummingbirds have sharp differences between the throat and chest, while other species have a blurry boundary or may be plainly colored. The sides of a bird's body are its flanks, and a hummingbird's flanks may show a color wash that can be useful in distinguishing different species. Comparing the flanks with the chest will also help determine which bird is which. Hummingbirds have very tiny, delicate feet that are held very close to the body and may look like small, dark spots when the bird is flying.
While all hummingbird feet look similar and cannot help distinguish different species by themselves, knowing where a hummingbird's feet can be seen will help you avoid mistaking them for color splotches.
Along with its back, a hummingbird's rump can be a good field mark for seeing the coloration of the upperparts. Some birds have different colors on the rump than on the back, and that contrast can also be a useful identification clue.
When a hummingbird is hovering to feed, observers have a great look at its undertail coverts. While many hummingbirds have plain white undertail coverts, any color wash, spots, or other markings can be excellent field marks for accurate identification. A hummingbird's tail is one of its most underappreciated field marks.
The length of the tail is the first clue to check, as well as whether there are any white or colored tips to the tail feathers. The positioning of the tail can also help identify the bird—is the tail splayed or held closed, or is it being pumped continuously while the bird feeds? When the hummingbird is perched , check the tail for a fork or whether the tip is smoothly rounded, and check to see if individual tail feathers are rounded or pointed. Learning how the parts of a bird can be seen on hummingbirds can help you more easily identify different hummingbird species.

Hummingbirds have a joint in the upper jaw, just behind the maxilla. This joint enables the maxilla to bend back toward the head slightly as the hummingbirds open their mouths.
When a hummingbird is less than one year of age, the maxilla is rough with corrugations along the sides and edges. Hummingbirds older than one year of age have smoother sides and edges.
A few adult hummingbirds will have some minor corrugations throughout their lifetimes. Belly: This is the soft portion of the hummingbird on the underside, just below the wings that hold all of the hummingbird's internal organs. Bones: In order to be as lightweight as possible, most of the hummingbird's bones are extremely porous.
Some hummingbird bones, like those in the wings and legs, are hollow to save even more weight. Brain: A hummingbird's brain is approximately 4. Hummingbirds are very smart and they can remember every flower they have been to, and how long it will take a flower to refill.
Breast: The breast of a hummingbird is located just below the chin and wings. This area is firmer than the belly because of the rib bones underneath. Cloaca: The area where liquid and solid waste mix and are expelled. Eggs and sperm are also released from the body at this location. Crop: The crop is a holding sac with a very thin wall that holds food and nectar to be digested.
After filling the crop, a hummingbird will rest while the crop empties itself into the digestive system. Ears: A hummingbird has two ears located on each side of the hummingbird's head. A hummingbird can hear better and easily decipher small fluctuations of tones better than most humans.
Erythrocytes: Erythrocytes are the red blood cells in a hummingbird's blood. Hummingbirds have the greatest concentration of erythrocytes than any other animal in the animal kingdom.
Esophagus: The esophagus on a hummingbird goes from the hummingbird's mouth to the crop. When a hummingbird eats or drinks , the food is transferred to the crop through the esophagus. Eyelids: Hummingbirds have regular eyelids to block light from each eye.
Hummingbirds also have a third eyelid call a Nictitating Membrane that is clear and will protect the hummingbird's eyes while flying. Eyes: Hummingbirds have very large eyes in proportion to their body weight. The eyes are set on the side of the head allowing the hummingbird to see both ahead binocular vision and on the side peripherally monocular vision.
The eyes are protected by twelve 12 or more bones surrounding it called ossicles. Hummingbirds have many more rods and cones than humans in their eyes to help them see well. This makes them better able to see colors and ultraviolet light.
Hummingbird's eyes will regularly outweigh a hummingbird's brain. Feathers: Some feathers on a hummingbird hold bright radiant color. This coloring comes from iridescent coloring like on a soap bubble or prism and requires sunlight to show these colors off.
An average sized hummingbird will have about feathers. This is more feathers per square inch of their body than any other bird in the animal kingdom. Feet: Hummingbird's feet are not for walking. Hummingbirds do not use their feet for launching upward in flight. They let their wings do all of this work. Hummingbirds use their feet for scratching and perching. They will perch for most of their lives. Hummingbirds have four 4 toes. Three 3 toes in the front and one 1 toe, also called the hallux in the back of the foot.
The hallux works much the same way a human's thumb does and allows the hummingbird to hang on to a branch or wire. Female Gonads: The female gonad is the female reproductive system.
These organs shrink during non-breeding months to make the hummingbird lighter for flight. Female hummingbirds are born with two ovaries. The right ovary will disappear soon after birth to lighten the hummingbird's body weight, leaving the left one fully functional. During breeding season, several ova mature in the ovary and produce a yolk.
Yolks are expelled into the oviduct. The yolks that are fertilized continue down the oviduct to the albumen gland. The albumen gland secretes a protein-rich substance called the egg white. The yolk and egg-white together will then continue down the oviduct to the shell gland where it receives a shell membrane that is made up of mostly calcium.
The male hummingbirds went crazy and loved feeling protected by the flowering plants along with the benefits of being closer to defending their food source. For further ideas on finding the best flowering plants for hummingbirds check out my post on: Increase Backyard Hummingbird Activity in 7 Days or Less.
Scratching is not nearly as fun and exciting as perching, but is extremely important to maintain personal hygiene for a hummingbird. Once the mites are removed, feathers will grow back in 3 weeks. Therefore, the hummingbird utilizes an interesting maneuver of dropping their wing forward, bringing their leg back and over their wing shortening the distance the foot needs to reach to provide access to their neck, head and beak while preening.
All of this takes place while the opposite leg balances the hummingbird on a wind buffeting tiny twig. Once the scratching is complete they will reverse the movements and tuck their leg back under their wing and continue to securely grip the branch or landing perch with both feet. They repeat this motion multiple times throughout the day. Hummingbirds become aggressive and territorial when defending their nectar or food source.
They will use their feet and beak to fight. Their long and pointy beak is the most obvious weapon, however they also use their feet when defending their territory or warding off a competitor. Since hummingbirds are professional agile aeronautic aviators, a slow motion video is needed to capture and document the behavior of hummingbirds fighting. A typical scenario is when hummingbird 1 flies up behind hummingbird 2 who is comfortably and quietly perched on a feeder.
Hummingbird 1 uses both of his feet, claws open and grabs the neck of hummingbird 2 forcing him down off of the feeder. If this maneuver does not provide the desired effect, the aggressor may use his beak as a weapon to push hummingbird 2 to get the solicited results and to emphasize his strength and dominance.
This action happens so quickly in real life that it looks like nothing more than a friendly push. This can be equated to a similar tactic used by a mother cat controlling her babies by grabbing them by the neck. When hummingbirds have a feud in mid air they will use their feet as a barrier or to grab the opponent while fighting.
They will expand and contract their tail feathers to make themselves appear larger to their rival and use their sharp bill to attack. Female hummingbirds not only use their feet to fight off predators, they also compress and configure their nest to fit two coffee bean sized eggs. While preparing her nest she gathers and assembles nesting materials using grasses, animal fur, cotton fiber, plant material, and small twigs to create a strong foundation.
She will make multiple venturing trips to locate and gather nesting material. When she returns, with the items perfect for building her nest in her beak, she will scan her surroundings to make sure there are no predators before placing her supply strategically on a specific location and meticulously stamp it in place with her feet.
The female will build her nest piece by piece, layering her nesting material with spider web silk which is the glue that binds the nest together. She may look like she is dancing, but she is working hard compacting the foundation and base of her nest. As a finishing touch she will gather more spider web silk. Using her beak,she will rub the outside of her nest to seal and increase its durability. The nest itself may take five to seven days to build.
They have plenty of other ways to use their feet and legs which includes such activities as perching, scratching, fighting and shaping a nest.
