Question

the word \peacock\ is often used to refer to both males and females of the indian peafowl species, but this is incorrect. technically, only males are peacocks, while females are peahens. peacocks have bright, iridescent blue and green feathers, as opposed to peahens, which are usually brown or gray in color. peacocks also have large trains, or tail feathers, that can grow up to five feet long. meanwhile, peahens have no trains at all. in the wild, both males and females may live alone or in small groups. during mating season, males use their multicolored tail feathers to attract females. however, it is usually the peahen who chooses a mate. peahens appear to prefer peacocks with the brightest, most symmetrical tails.

Explanation:

• "Peacocks have bright, iridescent blue and green feathers" so check the box for peacocks under "Have colorful feathers".
• "Peacocks also have large trains...peahens have no trains at all" so check the box for peacocks under "Have trains".
• "In the wild, both males and females may live alone or in small groups" so check both boxes under "Live in small groups or alone".
• "However, it is usually the peahen who chooses a mate" so check the box for peahens under "Choose which bird to mate with".

Answer:

• Have colorful feathers: Peacocks (checked)
• Have trains: Peacocks (checked)
• Live in small groups or alone: Peacocks (checked), Peahens (checked)
