The smallest bird is the Hummingbird zunzuncito which has only 64 mm in length and weighs only 2.8 grams. When you open its wings it does not measure more than a few 78 mm. But the largest bird known so far is the ostrich; they can reach a measure up to 2.74 meters high and can weigh up to 155 pounds. Of course, their eggs are huge with an average of 14 cm and 1.4 kilos of weight.
Some places have begun to raise ostriches for human consumption. Other species are admired and protected as some species of Eagles or Hawks, but all have something in common: a unique beauty.
