MCQ Detailed View

The correct answer is More. In many bird species, male birds are more colorful than female birds due to a biological phenomenon called sexual dimorphism, where males and females of the same species show different physical traits beyond reproductive organs.

The bright and colorful plumage of male birds primarily serves two purposes: attracting mates and deterring rivals. In most species, females choose mates based on the vibrancy of their feathers, courtship displays, or other visual signals. For example, male peacocks display their vibrant tail feathers to attract females, while female peahens have duller brown feathers to provide camouflage while nesting.

Coloration in male birds is influenced by pigments like carotenoids (reds, oranges, yellows) and structural colors (blues, greens), which are often obtained from their diet or created through the structure of feathers. This bright coloring signals good health, strong genetics, and fitness to potential mates.

In contrast, female birds are usually less colorful because they require camouflage to protect themselves and their young from predators. The duller plumage helps them blend with the environment while incubating eggs or feeding chicks, increasing survival chances for both the mother and offspring.

This difference in coloring is a key aspect of evolutionary biology, demonstrating how natural selection and sexual selection work together. While there are exceptions, the general trend across many species is that male birds display brighter and more vibrant colors than females.
