Explanation:
Warm-blooded are those animal species which can maintain a body temperature higher than their environment. In particular, homeothermic species maintain a stable body temperature by regulating metabolic processes. The only known living homeotherms are birds and mammals, though ichthyosaurs, pterosaurs, plesiosaurs and non-avian dinosaurs are believed to have been homeotherms. Other species have various degrees of thermoregulation.

Animal body temperature control varies by species, so the terms "warm-blooded" and "cold-blooded" (though still in everyday use) suggest a false idea of there being only two categories of body temperature control, and are no longer used scientifically.

Birds include all the birds, and their examples are like crow, eagle, sparrow, parrot, pigeon, peacock, hen, duck, etc.
The humans are homeotherms and have a constant body temperature of 37 °C.
A change in body temperature is an indication of health issue and metabolic disturbance. If the change is not corrected, it may even lead to death for these animals.
This constant temperature is possible due to homeostatic control in the body. The body temperature is such that there is only a small switch in the temperature in the upper and lower side.
Also, they have a temperature regulating center in their brains which keeps up the constant temperature.
The blood in these animals helps to distribute uniform temperature throughout the body.
Even they have protective factors in the body like the presence of thick fur, feathers, hard skin and even adipose tissue to counter cold temperatures
