Feeding bread to wild ducks is incredibly harmful. Bread has almost no nutrients that are useful for the duck, so they become malnourished and more susceptible to disease. Compounding the problem is excessive bread in the water, which leads to high levels of E. coli and even botulism outbreaks. Wild ducks need to stay wild, and artificially feeding them causes them to lose their natural instincts for acquiring food. If you want to feed captive waterfowl, consider chopped vegetables, whole grains, or fruit instead. ...

Inca terns are unique and beautiful birds—slender with white-tipped gray feathers, a white curly moustache, yellow lips and a bright orange-red bill. They have a distinctive call that sounds like a high pitched laugh, which is often accompanied by bowing gestures.

Inca terns are natives of the western shoreline of South America and the islands located offshore. They are especially abundant in northern Chile and Peru in the summer. They migrate in winter, venturing to Ecuador and central Chile.

Inca terns swoop down and pluck fish from near the water’s surface. They also sometimes get scraps left behind by whales, or flock to where sea lions are eating on rocks, to steal stray bits of food.

Potoos are a small New World family of solitary and nocturnal birds. Most are so poorly known they seem more fiction than substance, their gruff or wailing cries ghostly delusions of the dim nocturnal world they inhabit.

The Resplendent Quetzal (Pharomachrus mocinno) has a range running from southern Mexico to western Panama. Its sinuous, jade-green tail feathers once adorned the clothing of Mayan rulers and served as currency. Now, bird-watching tourism boosts local economies in quetzal territory.

Penguins may lack teeth, but they have backward facing spines in their throats that grip and guide fish down.

Well, obviously it's white, but take a look at its bill!

The attractive 7.5-inch-long bill is possessed by both male and female toucans. Interestingly, they use them during a mating ritual, pitching fruit to one another, but has very limited use as an excavation tool. Toucans make their nests in tree hollows found in rain forest regions of Southern Mexico, Central and South America, and the Caribbean region to which they are native.

The kiwi is a flightless bird found only in New Zealand. They're around the size of a chicken, and lay the largest eggs in relation to their body size of any bird in the world. Their eggs can be up to 20% of the females body weight - the equivalent of a 130 pound woman giving birth to a 26 pound baby.

A flying fish moves its tail up to 70 times per second to propel itself up and out of the water. Those specialised pectoral fins are spread wide and tilted slightly upward to provide lift, and then folded back against the body to lower the fish back into the ocean. Flying fish (family: Exocoetidae) are eaten by dolphins, tuna, birds, squids and porpoises, so they needed to develop an ingenious mode of escape - such as flying - in order to survive.
