Enjoy the beautiful wings of flight.
Some of these colored beauties were spotted at the local zoo while the rest were spotted in their natural environment.

![amitsoneji > Flamingos (Photographed at Riverbanks Zoo,SC,USA):
Flamingoes are the some of the only creatures designed to survive in the caustic environment of a volcanic lake. Equipped with a filter-feeding system unlike any other bird on earth, flamingoes' beaks have evolved to skim tiny algae from the water's surface. By swinging their upside-down heads from side to side or swishing water with their fat tongues, flamingoes siphon the lake water through their filters to trap algae. They can filter as many as 20 beakfuls of algae-rich water in a single second.
This unique feeding system gives flamingoes a certain security: while they must watch out for predators like jackals or eagles, they compete with no other animals for food.
Conservation Status:
Scientists have discovered that [flamingos] are dying by the thousands along the Rift Valley lakes of Kenya and Tanzania. However, they are baffled about the reason. Possible causes include avian cholera, botulism, metal pollution, pesticides or poisonous bacteria, say researchers. Also, fears for the future of the Lesser Flamingo — Phoeniconaias minor — have also been raised by plans to pipe water from one of their key breeding areas, the shores of Lake Natron. The lakes are crucial to the birds' breeding success because the flamingos feed off the blooms of cyanobacteria that thrive there.[5]
Most scientific attention has focused on the environmental changes to the lakes. Water levels have lowered and concentrations of salt in the water have increased. This increases the risk of toxic bacteria growing there
Cool Facts:
>> Diet -Flamingos filter-feed on brine shrimp. Their oddly-shaped beaks are specially adapted to separate mud and silt from the food they eat, and are uniquely used upside-down. The filtering of food items is assisted by hairy structures called lamellae which line the mandibles, and the large rough-surfaced tongue. The flamingo's characteristic pink colouring is caused by the Beta carotene in their diet. The source of this varies by species, but shrimp and blue-green algae are common sources; zoo-fed flamingos may be given food with the additive canthaxanthin, which is often also given to farmed salmon.Flamingos produce a "milk" like pigeon milk due to the action of a hormone called prolactin (see Columbidae). It contains more fat and less protein than the latter does, and it is produced in glands lining the whole of the upper digestive tract, not just the crop. Both parents nurse their chick, and young flamingos feed on this milk, which also contains red and white blood cells, for about two months until their bills are developed enough to filter feed.
>> Legs - Flamingos frequently stand on one leg. The reason for this behavior is not fully known. One common theory is that tucking one leg beneath the body may conserve body heat [4], but this has not been proven. It is often suggested that this is done in part to keep the legs from getting wet, in addition to conserving energy. As well as standing in the water, flamingos may stamp their webbed feet in the mud to stir up food from the bottom.](http://amitsoneji.smugmug.com/photos/185166624_2ZEkz-Ti.jpg "amitsoneji > Flamingos (Photographed at Riverbanks Zoo,SC,USA):

Ringed Bill Gull (Photographed in Charlotte,NC,USA):
A familiar parking lot gull, the Ring-billed Gull breeds primarily inland in North America. It can be found along the coasts, but many of these "seagulls" never see anything except fresh water all their lives.
Description:
Medium-sized gull.
Yellow bill with black ring near the tip.
Head and underparts white.
Back light gray.
Wingtips black with white spots.
Legs yellow.
Size: 43-54 cm (17-21 in)
Wingspan: 105-117 cm (41-46 in)
Weight: 300-700 g (10.59-24.71 ounces)
Conservation Status:
Hunting for the millinery trade nearly extirpated it from parts of range in 1800s. Now common and widespread, and is expanding its breeding range.
Cool Facts :
>> Young Ring-billed Gulls tested at only two days of age showed a preference for magnetic bearings that would take them in the appropriate direction for their fall migration.
>> Many, if not most, Ring-billed Gulls return to breed at the colony where they hatched. Once they have bred, they are likely to return to the same breeding spot each year, often nesting within a few meters of the last year's nest site. Many individuals return to the same wintering sites each winter too.
>> Although it is considered a typical large white-headed gull, the Ring-billed Gull has been known to hybridize only with smaller, black-headed species, such as Franklin's, Black-headed, and Laughing gulls.
