Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The males of a bird species do a “dance” and “sing a song” each spring. What is the main purpose of these behaviors?
A
to scare off young birds
B
to imprint young birds
C
to clean their feathers
D
to attract female birds
Explanation: 

Detailed explanation-1: -Courtship displays are a form of communication, enabling birds to signal their willingness to mate. They also give the birds an opportunity to assess their partner. A female bird invests a great deal of energy in producing eggs, incubating them, and raising the young.

Detailed explanation-2: -Courtship displays are behaviours aimed to facilitate attraction and mating with the opposite sex and are very common across the animal kingdom. Most courtship displays are multimodal, meaning that they are composed of concomitant signals occurring in different sensory modalities.

Detailed explanation-3: -Courtship behavior can include things like food delivery, dance moves (displays), and mutual preening. In many cases, the most extravagant courtship displays belong to the species where males contribute little else to the relationship-think strutting grouse or dancing birds-of-paradise.

Detailed explanation-4: -In a hilariously edited video, two male manakin birds is seen “practising” their dance, which they will later use to attract females. The manakin has also been known to “moonwalk.” The manakin though is not alone in its performative courting.
