The yellow-legged green pigeon is very slow, it is usually easy to see it early in the morning at the top of a tree feeding on wild figs. This bird is almost never seen on the ground, and its strong legs are perfectly adapted for climbing.
These pigeons move along the branches, moving their paws like parrots, and feed only on fruits. They love figs from banyan and pipal trees growing in the Indian capital Delhi.
Since these green pigeons are similar in color to leaves, the whole flock may be on the tree unnoticed and you will find it only during takeoff with a characteristic noise of wings
The red-eyed tree frog Agalychnis callidryas is a tree frog that lives in the rainforests of southern Mexico (Yucatan) and Central America.
These are nocturnal animals, during the day and during the drought season they hide on the underside of wide leaves, sleep on the tops of trees. During sleep, their bright red eyes are masked by the lower translucent eyelid, painted in a golden mesh, which allows the tree frog to see prey or danger.
With the onset of darkness, the tree frogs wake up, yawn, stretch, change their light green daytime color to dark green at night and announce the surroundings with a specific croak. They are capable of making very long jumps.
During rest, the eyes of the red-eyed tree frog are closed with a transparent membrane that does not prevent this frog from seeing the world around it. But if she is in danger, the tree frog immediately opens her eyes wide and confuses the predator with their bright red color - and these seconds are enough for her to instantly disappear!
Skunk puppies at the age of 8 days can already spray the enemy with caustic liquid, and at 24 days, when their eyes open, they will be able to "shoot" with aim.

They place the extracted food in the blind process of their esophagus (goiter). As the goiter increases, all the internal organs of the ant move away. The abdomen of the "storage" ant can increase 4-5 times and reach 6-12 mm in diameter.
In winter, when hunting and prey are reduced, the ant colony "uncovers honey barrels". To do this, the worker ants send special signals to the plerergates with their antennae. After receiving the signal, the "keeper" shares food with his relatives by trophallaxis.
