The World's Amazing Birds 2

This is the second list of amazing birds.

There are thousands of facts that we don’t know about amazing birds. One article is not enough to satisfy our curiosity for knowledge. The first “The Amazing Birds” article drew hundreds of positive feedbacks and some readers asked and requested if there could be a follow up article. So, here it is fellows, Part 2 of “The Amazing Birds”. Hope you'll enjoy reading it.

Smelliest Bird

The Hoatzin (Opisthocomus hoazin) is a tropical bird that lives in swamps, humid lowlands, backward lagoons and mangroves of northern and central South America. A slender bird about 65 cm in length, with small head and a long neck. Hoatzin is brown in color with featherless blue face and with spiky, Rufous crest. It also has maroon eyes and dark-brown back and buff underparts. What makes this bird amazing or odd — it has a smell similar to cow manure. This odor could be the byproduct when its diet of green leaves interact with a special digestive system

Most Creative Decorator

The Satin Bowerbird (Ptilonorhynchus violaceus) is found mostly along Australia’s southeastern coast living in woodlands, rainforests and nearby open areas. Younger ones are called ‘green bird’ with olive-green colored upperparts plumage, off-white underbody and brown wings. Adult males have shiny blue-black plumage and can grow up to 27cm to 33cm in length. The amazing thing about Satin bowerbird is the way it creates an elaborate “bachelor pad”. Studies show that males build this “bachelor pad” called bowers and decorates it with shiny objects specially blue-colored ones that may include: flowers, berries and even drinking straws and other useless plastic items.

Most Skilled Nest Builder

The Southern Masked-Weaver (Ploceus velatus)is found throughout southern Africa inhabiting woodlands and grasslands. It has a yellow head, an orange eye, a black bill and yellow-green underbelly. What’s amazing about this bird is the way it builds its nest. In just five days it makes an intricate sphere-like nest from grass with a bottom entrance that hangs from the tip of an overhead branch.

Largest Wingspan

It breeds on flat, open, oceanic or barrier islands of sand rich in fish, squid and plankton. It is about 33-36 cm long with a 82-94 cm wingspan. What’s special about sooty tern is that it leaves its nesting grounds as a juvenile and remains in the air for 3-10 years, settling in water from time to time. It then settles back to land as an adult to breed.

Fastest Swimming Bird
