Males in many bird species have bright colored feather that makes them conspicuous to predators and reduces their survival, yet they posses these traits. Which of the following is NOT true about such traits? Females will not show a preference for such traits, because they know that the traits will be inherited by the offspring making them vulnerable to predation. These showy traits help male birds secure more mating opportunities. Such traits may have evolved due to selection for these traits by females.

Elaborate male traits that are used in mate choice of birds in a given species B are entirely absent in distantly related sister taxon, C. The last common ancestor of these birds, species A, also had males that were elaborated decorated. Which is more likely to have evolved first in species B, the male trait or the female preference?

Males a particular bird species have a bright blue crest of feathers on their heads. Females are attracted to males with larger and brighter blue crests, and more females mate with such males. However, the crests also make them conspicuous to predators such as hawks. Which of the following populations is likely to have more males with small pale blue crests and very few males with large bright blue crests? A population in a dense forest where the birds are not very visible to hawks. A population in which there are other species with blue feathers. A population in which there are plenty of mating opportunities. A population in a habitat that has very few trees, making it easier for hawks to see these birds.
