Colonel Hathi breaks his stick; in the next scene it is intact, then broken again.
When Baloo is fighting Shere Khan, the landscape is desolate and littered with dead trees. After the fight, when Baloo is lying unconscious with Mowgli and Bagheera looking over him, the landscape is the jungle again, full of live plants and trees.
Shere Khan's stripes on his forehead are absent throughout the movie, but are visible during the extreme close up during his entrance.
When Shanti is kneeling by the water at the end, singing, as she fiddles with one of her pigtails and flips it back, you can see that it is still tied with the purple ribbon. However, the shot right after she fiddles with her other braid shows both ribbons as missing and her hair loose.
When Bagheera drops baby Mowgli off with the wolf pack, he leaves the basket at the mouth of the cave den. When he leaves the baby, the basket is closed and when he looks back from his hiding place, the basket is open.
Hathi, a bull Asian elephant, is the leader of the elephant when in reality elephants are a matriarch society. The herd is led by the top cow elephant (Winifred). Once a bull elephant becomes matured, he would either go alone or join a group of other bulls.
Winifred, Hathi's mate, is apparently the only female elephant in her herd. In real life elephant herds mostly consist of females while males live alone once they reach adulthood, though some males also live in 'bachelor' herds.
Wolf cubs do not wag their tails when they are curious. The tail wag among wolves is largely a sign of submission.
Baloo despite being a sloth bear is about the size of a grizzly bear. Sloth bears are actually one of the smallest bears in the world.
Kaa closes his eyes several times in the film but snakes do not have eyelids in real life.
The story takes place in India, yet King Louie is an orangutan - they live in Borneo and Sumatra. Disney's promotional materials later solved this problem by declaring that Louie is an undiscovered "cryptid" species, which is also mentioned in The Jungle Book (2016).
After the fight with the monkeys Baloo and Bagheera have black eyes. They seem to be reversed at one point, but that's because they're looking at reflections in a pond.
King Louie lacks the beard and floppy cheeks of a real male orangutan. If he is a fictional species, as promotional materials claim, this ceases to be a problem.
King Louie shows three fingers instead of two when he tells Mowgli to have two bananas.
This was done for two reasons: 1) King Louie can't count. 2) His hand was backwards when he held up his fingers, and in some countries, a hand turned backward with two fingers up is a considered a rude gesture.

During "The Bare Necessities", when Baloo sings "I'll tell you something true", and prepares to belly flop out of the water, a whitish streak appears on his right arm for one frame; this most likely was due to a colorist's error.
During "The Bare Necessities", when Baloo is about to fly off the waterfall, his right arm is incorrectly colored yellow for one frame, likely a colorist's error.
When Kipling named his animal characters, he tried to use the Hindi term in the name. For example, bhaloo is a bear. Kipling made an error when naming Sher, though, as it means "lion" instead of "tiger."
There are several scenes in which the same animation is reused for the Colonel Hathi and his elephants march during the song. Since they sing different lyrics during this piece of animation, the mouth movements do not match what they are saying. This is most noticeable when they cross the water.
During the "I Wanna Be Like You" song, King Louie says "One more time!" Baloo appears to be mouthing the words, but his voice isn't heard.
When Bagheera is trying to pull Mowgli away from the tree, you can hear Bagheera demand "Let go, you", and Mowgli replies, "You let go of me!" However, neither of their mouths are moving.
The monkeys are hanging from their tails in several scenes, but monkeys with grasping tails are only found in South America.
Set in India, yet the monkeys' ruined city is clearly Cambodian.
During the "The Bare Necessities" song, Baloo is shown picking the fruit off a prickly pear cactus and a pawpaw, which he acknowledges by name. These types of plant only grow in North America.
Despite the film being set in India Hathi's ears resemble those of an African elephant which as the name suggests are native only in Africa.
Baloo asks Mowgli to scratch his left shoulder, however when Mowgli scratches him, he scratches his right.
In the beginning, Bagheera refers to the wolf children as cubs. Baby wolves are known as pups and not cubs.
When Bagheera argues with Baloo, Bagheera incorrectly calls the monkeys "apes". Most monkeys have tails, but no apes do.
