Size
Egg size tends to be proportional to the size of the adult bird, from the half gram egg of the Bee Hummingbird to the 1.5kg egg of the Ostrich. Kiwis have disproportionately large eggs, upto 20% of the females body weight. This evolutionary trait results in kiwi chicks that can emerge from the nest days after hatching, ready to start foraging for food.

Famous quotes containing the word size:
“There are obvious places in which government can narrow the chasm between haves and have-nots. One is the public schools, which have been seen as the great leveler, the authentic melting pot. That, today, is nonsense. In his scathing study of the nation’s public school system entitled “Savage Inequalities,” Jonathan Kozol made manifest the truth: that we have a system that discriminates against the poor in everything from class size to curriculum.”
—Anna Quindlen (b. 1952)
“For truly I tell you, if you have faith the size of a mustard seed, you will say to this mountain, ‘Move from here to there,’ and it will move; and nothing will be impossible for you.”
—Bible: New Testament, Matthew 17:20.
“It is very considerably smaller than Australia and British Somaliland put together. As things stand at present there is nothing much the Texans can do about this, and ... they are inclined to shy away from the subject in ordinary conversation, muttering defensively about the size of oranges.”
—Alex Atkinson, British humor writer. repr. In Present Laughter, ed. Alan Coren (1982)
