Question

Study of migration of birds is known as
A. Entomology
B. Ornithology
C. Phenology
D. Nidology

Answer 1

Hint: Migration is the process of movement of animals in search of food and shelter over long distances and sometimes to escape the harsh environmental conditions. Migration movements can be short distance i.e local or long distance i,e in which they can even travel the continents.

Complete answer:
The correct answer is (C).
Phenology is the study of the migration of the birds from one place to another.
The migration of the birds is the regular and seasonal movement, which mainly occurs north and south along a flyway and between breeding and the wintering grounds. The migration of the birds is carried by many of the species. The process of migration results in high costs in predation and many birds die during these movements thus mortality rate is also very high. Migratory birds are even hunted by humans or some die due to the unavailability of food and water during their course.
Birds are the animal that belongs to the phylum Aves. They have pneumatic bones which are hollow from inside and thus help them during flying. Their wings are modified into feathers which are the organs for flighting and also act as insulators thus preventing the body heat to escape out and thus keep them warm. They are warm blooded animals and they have additional chambers called crops and gizzard in their digestive system. The skin of birds is dry except the presence of oil glands.

Note: The ornithology is the study of the birds, their behaviour, eating habits, flying patterns, their crawls, nesting habits and other features, it should not be confused with phenology.
