Largest brain, relative to size, of all birds. The brain is 4.2% of total body weight. Hummingbirds have proportionally the largest hearts of any living animal. 1.75% to 2.5% of body weight. Resting heartbeat is 480 beats per minute and can go as high as 1,260 per second when excited. Resting hummingbirds breathe 250 times a minute.
BILL: Unlike most other birds, hummingbirds bills have a pronounced overlap, with the upper bill curving around and over the sides of the smaller lower bill. When hummingbirds feed, the bill is usually only opened slightly, allowing the bill-shaped tongue to dart out and into the interior of flowers. The bill is rarely opened wide and in any case is limited in how far it can be opened, but is used for variety of tasks, including catching insects in flight, preeming feathers, carrying nesting material, constructing nests, feeding baby hummingbirds and attacking rivals.
The shape of a hummingbirds wing is kind of "D-shaped" and of course very small.
A cat's ears are that of a triangle shape.
Hummingbirds build tiny, cup like nests, which are attached to tree limbs with spider webs and saliva.

Hummingbirds are attracted to flowers that are tubular in shape and brightly colored, such as trumpet-shaped flowers or those in shades of red, orange, or pink. Some common flowers that provide hummingbirds with nectar include bee balm, salvia, and trumpet vine. These flowers have adapted to attract hummingbirds as pollinators due to their unique shape and nectar production.
Panthers, which are typically black leopards or jaguars, do not have pointy ears; their ears are more rounded. Unlike some other big cats, such as lynxes, which have distinctly pointed ears, panthers have ears that are softer in shape and blend more with their rounded heads. The ear shape can vary slightly depending on the individual and their specific subspecies, but overall, they are not characterized by pointy ears.
