[Daily article] August 7: American white ibis Published On

The American white ibis is a species of bird in the ibis family, found
from the mid-Atlantic and Gulf Coast of the United States south through
most of the New World tropics. It is a medium-sized bird with an overall
white plumage, bright red-orange down-curved bill and long legs, and
black wing tips that are usually only visible in flight. Males are
larger and have longer bills than females. Crayfish are its preferred
food in most regions. During the breeding season, the American white
ibis gathers in huge colonies near water. Pairs are predominantly
monogamous and both parents care for the young, although males tend to
engage in extra-pair copulation with other females to increase their
reproductive success. Males have also been found to pirate food from
unmated females and juveniles during the breeding season. Human
pollution has affected the behavior of the American white ibis via an
increase in the concentrations of methylmercury, which is released into
the environment from untreated waste. Exposure to methylmercury alters
the hormone levels of American white ibis, affecting their mating and
nesting behavior and leading to lower reproduction rates.

   If the government can round up someone and never be required
