Question

Birds fly from place to place, this movement is termed as-
A. Cursorial
B. Scansorial
C. Digitigrade
D. Volant

Answer 1

Hint: Bird migration is the regular seasonal movement of birds between breeding and wintering areas, usually north and south along a flyway. Many bird species migrate. Predation and mortality, including human hunting, are significant costs of migration, which is mostly driven by food availability. It is primarily seen in the northern hemisphere, where natural forces funnel birds into precise routes.

Complete explanation:
Option A: If an animal has the ability to run quickly or maintain a consistent speed over a long distance, it is considered cursorial.
So, option A is incorrect.
Option B: Scansorial animals are animals that have evolved to climb. Scansorial adaptation refers to organisms that have been modified to live on walls, rocks, tree branches, or in an arboreal setting.
So, option B is incorrect
Option C: Cats and dogs are digitigrades, which stand or walk on their digits or toes. Digitigrades move faster and more softly than most other animals.
So, option C is incorrect.
Option D: In general, the word volant indicates "flying" or "capable of flying." Volant refers to the movement of birds from one location to another.
So, option D is correct.

Hence, Option D is the correct answer.

Note:
The adaptations made by animals who live in an airborne manner of life or spend the most of their time flying are known as volant adaptations. They must keep their bodies in the air and adapt for propulsion. A volant animal's body must be light and rigid. During flight, the muscles require a constant flow of energy and strength. Animals must also learn to adjust to changes in speed.
