Pelecanus onocrotalus
When we think about birds with massive wingspans, the Albatross comes to mind. But did you know that Pelicans can be just as gigantic? Even though it is the second in average size to the Dalmatian Pelican, the Great White is able to sport a larger wingspan-- close to 12ft!

Great White Pelicans live near shallow bodies of freshwater, and most of the birds are migratory. During the summers they live in slightly cooler parts of Europe and Asia, and during the winter they move to northern Africa, the Middle East, and south Asia. There are a few resident populations as well, and those are found in sub-Saharan Africa.

The Great White Pelican lives its entire life in a large group. They feed, breed, and migrate in colonies. Unsurprisingly with a bill that large, these birds are excellent fishermen, which is good because each birds needs to eat about 3lbs of fish every day. They actually spend very little time hunting every day, and are normally finished by late morning. The Pelicans spend most of their time bathing, preening, and monitoring their territory.

Though the Great White Pelicans are currently listed as being of Least Concern, some populations are declining and Europe. Also, the birds are being forced to move farther and farther away to do their hunting, as human overfishing is affecting their stocks. Humans also hunt the Pelicans themselves-- their pouches are used for tobacco bags, and their skin and meat is also valued.

Ceryle rudis
The Pied Kingfisher is one of the most common Kingfishers in the world. You'll find them throughout sub-Saharan Africa and Asia, where they live in lowland regions near bodies of water.

Pied Kingfishers are very distinctive in appearance. They have white faces with black masks, stark black bills, and patchy (pied) white and black feathers on their crest, back, and wings. Males and females differ in their chest bands-- males have two, females only one.

Fish are the primary prey of the Pied Kingfisher, though aquatic insects and crustaceans will also be consumed. They hunt by hovering over the water, and once they spot prey they dive in with their large bill first and snatch it up. They can swallow small fish whole, which allows them to hunt longer (rather than returning to a nest to feed).

Pied Kingfishers do their nesting in holes that they dig out in vertical sandbanks. These holes can be more than 4ft long, and can take up to a month to excavate. As many as seven eggs are laid at a time, and mom and dad often have help in raising their brood-- chicks from the previous year often stick around to help out their younger siblings, and non-breeding adults will sometimes also lend a hand.

Burhinua bistriatus
Meet the Double-striped Thick-knee, a wading bird native to South and Central America. During the day it is very difficult to spot them, as they have striped, patterned plumage that allows them to blend in will with tall grasses.

Night time however, is a slightly different story. They are nocturnal creatures, and make very loud vocalizations. So even though you may not seen them in the dark, you'll probably hear them!

Double-striped Thick-knees feed on insects, worms, and small reptiles and rodents. They are generally monogamous birds, and each pair will raise 2 precocial chicks each breeding season.

At present, the Double-striped Thick-knee has a large enough range and population size to be listed as Least Concern. The population is currently on a stable trend, and there may be as many as 5,000,000 birds out there!

Platalea minor
Of all the Spoonbills in the world, only the Black-faced Spoonbill is considered to be Endangered. It is estimed that there are around 2,700 of these wading birds left in the world, and they
breed only on a handful of islands off the coast of Korea and the Liaoning Province of China.

Black-faced Spoonbills have white-feathered bodies, with black bills and faces. During the breeding season their neck feathers turn yellow, and they also develop a crest along the back of their head. They breed in May, building nests on cliffs, and spend their non-breeding time living in coastal wetlands and mudflats. Their spoon-shaped bills help them to dredge up small fish and crustaceans.

These birds are endangered due to habitat loss. The wetlands that they live in are being drained for development and agriculture. It also doesn't help that they have very few wintering sites (specific locations in Hong Kong, Macau, Taiwan, and Vietnam). Should something happen to any of those sites (natural or man-made), the birds would be in even more trouble. Black-faced Spoonbills are protected in most of their breeding and wintering ranges, and a survey is being continuously done to track their numbers.

Phoenicoparrus jamesi
The James's Flamingo is a small South American species that lives high up in the plateaus of the Andean Mountains. They feed off of different algae and diatoms that are found in high elevation saline lakes. Like all Flamingos  they are excellent filter feeders, and use their long necks and curved bills to dunk their faces in the water and snatch up tiny meals.

This species is the palest pink of all the Flamingos, and can also be told apart by their red eye patches, bright yellow bills, and orange legs. They are named for naturalist Henry Berkeley James, who went on expeditions to the Andes in order to collect species of natural flora and fauna in the late 19th century.

James's Flamingos have a favorite breeding location -- Laguna Colorada in Bolivia. They gather there in the thousands, and perform giant group displays prior to finding a mate. Once mates are selected, the two birds will stay together until one dies. They produce only one egg each season, laying it on a volcano-shaped nest built out of mud. Chicks are born with fluffy grey feathers, but will gradually lighten and turn more pink over time. It can take up to six years to reach sexual maturity.

IUCN Status : Near Threatened
Location : South America

Egretta rufescens
The Reddish Egret is an appropriately named species of Heron that can be found in Central America, and around the Gulf Coast in the United States. They stand a little under 3ft tall, and typically sport long dark legs, reddish heads and necks, and slate-grey coloration on the wings and back.

Do not confused them with Snowy Egrets! Now, you may wonder how anyone could mistake a red and grey bird for an all white one, but it happens! You see, Reddish Egrets have a white color morph. This means that they sometimes turn out completely white, much like their Snowy cousins. The two actually do have a slight overlap in ranges, so the easiest way to figure them out is by the color yellow. Snowy egrets have some yellow on their beaks and feet, Reddish Egrets do not.

Reddish Egrets are most active during dusk and dawn, and they are usually seen on the move. They hunt for prey in shallow waters, running around in search of Fish, Amphibians, and Crustaceans. The Herons often move about with their wings outstretched, as this creates shade and reduces glare on the water surface.

As far as reproductive issues are concerned, the Reddish Egret reaches sexual maturity around 4 years of age. Their courtship displays include head bobs, chases, and various flights, but once a mate is chosen they remain monogamous for at least that season. The couple will build a nest together, either on the ground or in a tree, and they often nest in very large colonies that can contain hundreds of birds. They lay up to 4 eggs, and the color of the chicks depends on the color of the parents. Dark morph parents can have chicks of either color, but two white morph parents will always have white morph offspring.

Reddish Egrets are listed as Near Threatened due to habitat degradation. Like many other birds, they were hunted extensively in the 19th century for their feathers, but their population has since rebounded.

IUCN Status : Near Threatened
Location : North and Central America
Size : Length up to 32in (.8m), Wingspan up to 50in (1.3m)

Cinclus cinclus
Allow me to introduce you to the White-throated, or European, Dipper. These aquatic Passerine birds can be found throughout the European Continent, as well as in western Asia, either as residents or seasonal migrants. They live near fast flowing streams and rivers, and prefer cold climates.

They are rather round little birds, measuring about 7in long and sporting short beaks and tails. They have black backs, brown heads, and a bright white throat that leads to a chestnut-colored band on the lower neck. Males and females look alike, and juveniles are greyish-brown overall.

Though they look like your average songbird, White-throated Dippers are one of five members of the Cinclus genus that actually swim underwater for their food. They have short, but strong wings that can be used like flippers, nose flaps to keep water out, and dense feathers that can be preened to be waterproof. They can swim underwater for about 30 seconds at a time. They do all their hunting by sight, and have an additional eyelid-membrane that protects their eyes while hunting for aquatic insects and small fish underwater.

White-throated Dippers are usually monogamous, and they lay their eggs quite early-- sometimes as early as late February! The adults teach their young how to feed, and the baby birds first learn how to hunt and swim in shallow pools. After fledging, it can take from 1 to 2 weeks for the juveniles to leave and go out on their own (depending on their learning speed).

IUCN Status : Least Concern
Location : Europe, parts of Asia
Size : Body length up to 7in (18cm)

Gavia arctica
Meet the Black-throated Loon, also known as the Arctic Loon and the Black-throated Diver. (The name we'll use today is a compromise between the other two names, a name thought up by the International Ornithologists Union). These migratory birds can be found across Europe and Asia, breeding in the northern, Arctic areas, and wintering further south. There are also some populations in Alaska and Canada.

Black-throated Loons have grey faces, black throats, and checked backs. Their breeding plumage also differs from their non-breeding plumage-- non-breeding has a white chin and drabber hues overall.

As the "Diver" name suggests, these birds are experts at diving for their food. They plunge underwater to catch their prey, which consists of fish, amphibians, and crustaceans.

Black-throated Loons are listed at Least Concern because they have a truely gigantic range, and because their population is very large. While it is on a slight decline, it is estimated that there are as many as 1.5million of them.

Check out the video below to hear some of their calls!


IUCN Status : Least Concern

Ixobrychus sinensis
The Yellow Bittern is a small species of Heron that lives in southern and eastern Asia. They only grow to sizes of around 15in (about a quarter of the size of the largest Heron-- the Goliath Heron!) The name comes from the coloration of the male, who is a dull yellow-brown with lighter undersides. Females are streaked brown. They are difficult to spot while not in flight, as their colors camouflage them in the reeds and other aquatic plants.

Yellow Bitterns are, on the whole, resident birds, though some that live further north will seasonally migrate small distances. They live in freshwater wetland areas like marshes and ponds, and even near man-made canals and reservoirs. There they feed on fishes, amphibians, and insects.

In places closer to the equator, where the temperatures remain more consistent, the Yellow Bitterns breed year round (elsewhere they have more defined seasons). Males attract females by hunching up their necks, puffing out their chests, and performing a series of calls (their bills also take on a reddish color at the base). The parents will construct a nest together, built near water using reeds and other plants. 3-5 eggs are laid at a time, and incubation duties are shared by both the mother and father.

Yellow Bitterns have a very large range and a large population size, so they are currently listed as being of Least Concern.

IUCN Status : Least Concern
Location : Asia
Size : Length up to 15in (38cm)

Bugeranus carunculatus
There are 15 species of Crane in the world, and we've talked about a few of them already-- tall, elegant birds that are symbols of luck and serve as national icons. (On a side note, you can see all fifteen Crane species in one place at the International Crane Foundation in Baraboo, WI. I'll make it out there one of these days...)

Anyway, today's Crane is a little less... beautiful... than some of its relatives. But it is still a very statuesque bird, albeit one with some interesting facial features. The Wattled Crane, as I'm sure you can deduce, has a red, warty-looking wattle that hands down from its neck and beak. Though its face is a little different, it still has the same long legs and feathers possessed by members of its family. (The tail feathers are so long they nearly touch the ground!)

Wattled Crane
Wattled Cranes are actually the tallest Cranes in Africa, and the second tallest Cranes in the world-- they can stand as high as 6" (1.8m). They also sport an 8.5ft (2.6m) wingspan. You'll find them living in the wetlands of Sub-Saharan countries, with the largest groups found in Zambia, and in Botswana's Okavango Delta.

The Wattled Cranes, like all Cranes, are omnivores. They feed on insects, grains, seeds, amphibians, and aquatic plants. Also in true Crane fashion, they perform elaborate courtship rituals and pair bonding dances. They jump, flap, bow, and vocalize during these performances. Wattled Cranes mate for life, and live in small flocks. They build nests on the ground, and lay only one egg or two each season (though usually only one will survive).

Sadly, the Wattled Crane is a Vulnerable species. Because they are so Wetland dependent (other African Cranes are more terrestrial) they are especially susceptible to habitat loss due to draining and development. There are around 8,000 left in the wild.

IUCN Status : Vulnerable
Location : Africa
Size : Height up to 6ft (1.8m), Wingspan up to 8.5ft (2.6m)

Calidris alpina (breeding plumage)
Meet the Dunlin, a small wading bird that can be found all over the Northern Hemisphere (depending on the time of year). Populations breed in the northern reaches of Europe, Asia, and North America, and migrate south as far as Africa, Southeast Asia, and Central America during the winter. The species is highly gregarious, especially in winter, and can be found in massive flocks that number into the thousands. The worldwide population as a whole is estimated to be around 4 million birds.

Dunlins are easy to identify in their breeding plumage. They have bright reddish-brown feathers on their backs and a large black patch on their underside. During the winter their backs turn a duller grey and the underside is pale. Dunlins are also easy to tell apart from other Shorebirds in that their long black bills curve downwards. They use those bills to probe into mud and shallow water for insects, crustaceans, and other small creatures.

When the breeding season rolls around, males are the first ones on the scene. Females get to the nesting ground after, and the birds pair up. They are monogamous during the season, and some pairs will continue to couple up year after year. Males start out the nest building process, scraping a few possible locations into the ground. The female will pick the location she likes the best, finishing the construction at the site.

Young Dunlins are precocial, and are flying after only 3 weeks. Interestingly, the mother usually abandons her family within the first week of hatching, and it is the father who cares for the offspring until they are fully fledged.

IUCN Status : Least Concern

Mesembrinibis cayennensis
The Green Ibis is a short little wading bird that also happens to be the only member of its genus. It can be found in Central and South America, living in wetlands and swampy woodland areas. These birds are typically residents of an area, though some may make very small migrations during the dry season.

Though it may not look it, depending on the light, the Green Ibis is actually green. It's a dark green, and sometimes it appears black, but it's green nonetheless. Juveniles have the same coloration, only it is more dull. They look quite a bit like the Glossy Ibis, but are more broad and have shorter legs.

You will find the Green Ibis living either alone, or in very small groups. Pairs are monogamous, and will build large platform nests in the trees, laying between 2 and 4 eggs each brood. They feed on water creatures like fish and frogs, and will take insects as well.

The species has a decreasing population, but it is still very large and they have an extensive range. They are currently listed as being of Least Concern, but that may change in future years.

IUCN Status : Least Concern
Location : South America
Size : Length up to 22in (56cm)

Mycteria cinerea
Today's animal is the Milky Stork, a tall bird with a milky-white body and black flight feathers. They can be found in the marshes, mudflats, and mangroves in Indonesia, Cambodia, and Malaysia. They breed in large, multi-species colonies during the dry season, building nests that can be several feet in diameter.

Milky Storks were historically found throughout Southeast Asia, but they are now locally extinct in several countries and are on the sharp decline in their remaining range. It is estimated that there are only 5,000 of them left in the wild. What are the threats behind this population plummet? Hunting and habitat loss. Land development for agriculture has destroyed many of the mangrove nesting sites that the birds rely on, and they continue to be hunted for food and feathers (eggs are also taken).


It has been illegal to trade Milky Storks internationally since 1987, but domestic exchanges still occur. The birds do appear in some protected areas, and are legally protected in Malaysia and Indonesia, but only time will tell with this species. Captive populations have been breeding successfully, but reintroduction has been slow and less successful than hoped for (though two chicks did hatch in Malaysia in 2010).

IUCN Status : Vulnerable
Location : Southeast Asia

Tringa erythropus
The Spotted Redshank is quite the little traveler. These birds spend their summers in Scandinavia and in parts of Siberia. When the autumn comes, they head south. Some go as close as the British Isles or the Mediterranean, while others make it all the way to Southeast Asia and even Australia! These migrations can start as early as late June, and will take months to complete with several stopover points.

Spotted Redshanks are wading waterbirds that can be found in marshes, forests, and wetland regions in whatever country they happen to be in at the time. They feed on very small water dwelling creatures, usually insects and their larvae, though they will take small vertebrates on occasion as well. Spotted Redshanks typically wade in order to feed, but they will also swim into deeper water and upend themselves like ducks do.

The population of Spotted Redshanks is currently stable, but that may not always be the case. Habitat degradation is happening in many of their winter and summer homes, as well as in many of their extremely important migration stopover points. For now though, their population size and massive range is enough to keep them listed as being of Least Concern, though they are listed by the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).

IUCN Status : Least Concern

Podiceps auritus in breeding plumage with offspring
Meet the Horned Grebe, a migratory bird that can be found in North America, Europe, and Asia. They breed far, far inland during the summer months, and during the winter they hang out further south along the ocean coasts.

When it comes time to breed, Horned Grebes are unmistakable. They have fantastic summer plumage with bright reddish feathers, a dark head, and huge light puffy tufts over their eyes. Those puffs give them their "horned" name. During the winter months they are far less colorful, sporting black and white feathers with no tufts.

Winter Plumage
Feathers play an important role in Horned Grebe digestion. Adults actually eat some of their own feathers in order to create an internal plug. This plug serves as a filter to keep bones and other slower digesting materials in the stomach longer. Parents even feed feathers to their babies to get this plug started!

And while we are on the topic of baby Grebes, did you know that they often ride along on their parents' backs while swimming? And because the adults usually feed on critters that they find underwater, this means the little ones get to go on dives too!

Ardea alba
Are you ready to get confused? Here we go.
This is the Great Egret. Or Great White Egret. Or Great White Heron. It looks like a Snowy Egret, but it's bigger. It also has the same common name as a Floridian color variation of the Great Blue Heron... which is white... and is also called the Great White Heron.

But thankfully we have scientific names! So no matter what you call today's bird, Ardea alba is how it will always be known to science... well, unless they find some weird discrepancy down the road that requires reclassification. But let's not add on to the confusion any more...

For the sake of this post, we'll go with "Great Egret," since they are quite large and majestic. They have a distribution that spans most of the world, with some populations living in a range year round, and some migrating North and South seasonally.

Great Egrets nest in large colonies, often sharing the space with other bird species. They build their large nests up in the trees, and parents are monogamous. Clutches of three or four eggs are the most common, but unfortunately it is rare for all chicks to survive to adulthood. Aggression between offspring is incredibly common, and the larger chicks will often kill their smaller siblings in order to receive more food.

Like many beautifully plumed birds in North America, Great Egrets saw a population dip in the late 19th century, due to the popularity of feathers in womens' hats. Conservation measures have allowed the North American Egrets to rebound, and in 1953 the Great Egret was chosen as the symbol of the National Audubon Society.

Mycteria leucocephala
The Painted Stork is a rightly colorful wading bird found in south and southeast Asia. They have bright yellow beaks, orange-ish heads, black and white banding across the body and wings, and bright pink tertial feathers. Males and females share that same bright coloration, though you can tell the sexes apart by the body and beak size (males tend to be larger).

The coloration on the Painted Stork also becomes more dull when it is outside of the breeding season. Plumage plays an important role in finding a mate, as does dancing! When seeking out a partner, the male Storks perform elaborate bows. If a female likes the male's bow, they will do a bit of a dance. One paired up the couple will go on to build a platform-like nest out of sticks and vegetation. These birds are highly gregarious during the breeding season, and sometimes nests end up almost on top of one another. Both parents incubate the eggs and feed the hatched chicks using regurgitated fish. Delicious!

As adults, the Painted Storks use their large bills to forage. They wade very slowly in shallow water (typically less and 1ft deep), and probe around with their bill partially open. If they hit something, they snap their bill shut. Fish make up most of the diet, though they do also eat Amphibians and Crustaceans.

Painted Storks are listed as Near Threatened because of habitat loss, hunting, and pollution. The birds do live within some protected areas, but the population continues to be on a downward trend.

IUCN Status : Near Threatened

Grus japonensis
The Red-crowned Crane is a large species of bird that can be found in the rivers and marshes of East Asia. They are the heaviest of the Crane species, and are also the most aquatic; they live, breed, nest, and feed there. The Crane's diet consists of fish, insects, amphibians, and a wide variety of reeds and aquatic grasses.

Red-crowned Cranes are also sometimes referred to as Japanese or Manchurian Cranes. They are symbols of peace, long life, and fidelity in their native countries, and have long been represented in folklore and art. These birds are popular icons in Japanese wedding ceremonies, as the Cranes form lifelong monogamous pairs that frequently dance and sing to one another. They were also designated as one of Japan's National Animals in 1952.

Despite the reverence and persistence in culture and folklore, the Red-crowned Crane almost went extinct during the 20th century. Hunting, habitat loss, and devastation caused by World War II reduced the Japanese population down to only a handful of birds, and similar threats damaged populations elsewhere.

The species is now protected in Japan, South Korea, North Korea, and Russia. Other conservation efforts include the creation of supplemental feeding stations and the installation of bird-visible power lines. The population is rebounding, but wetland drainage and development continue to pose threats. Interestingly, the Demilitarized Zone has become a popular spot for these birds, but the fragile political nature of that area could cause the birds to lose this now human-free habitat.

Egyptian Plover at the Milwaukee County Zoo
The Egyptian Plovers have long been one of my favorite birds at the Milwaukee Zoo, but before I got my new camera I could never get good shots of the enclosure. Well my photo drought has ended!

I'm drawn to this little bird by its small size and striking, contrasting colors. What a looker! This, and their nesting habit (which we will get to later) make them a very distinctive shorebird.

Egyptian Plovers can be found living near sandy riverbeds throughout Sub-Saharan Africa. They are sometimes called "Crocodiles Birds" due to a 5th century BCE account by Herodotus stating that they pick food from between a Crocodiles teeth. The story has persisted, but there is no actual proof that the birds engage in this risky feeding behavior.

In reality, Egyptian Plovers feed on insects, seeds, and the occasional mollusk. They tend to remain sedentary, and breeding pairs will aggressively defend their territory. These couples will produce 2-3 eggs at a time which they bury them in the sand! Burying the eggs helps to keep them warm, and also helps to protect them from the eyes of hungry predators. But sometimes the eggs get too hot, so in order to cool them down the parents will wet their feathers and use the water to chill the eggs. Baby Plovers leave their "nests" when they are only a day old, though they will stick around their parents for about a month.

Anastomus lamelligerus at the San Diego Zoo
Meet yet another cool animal that I encountered on vacation... albeit one that has significantly less written about it.

This is the African Openbill Stork, a species that can be found throughout the wetlands of the Sub-Saharan Africa in resident populations.

Though the dude in my picture is playing with a dead mouse, these large birds most commonly feed on snails and various bivalves in the water. They have special beaks that let them sever the snail shell muscles to get to the meat. Other critters can take longer to kill.

African Openbill Storks live in colonies that are comprised of several dozen breeding pairs. These pairs are monogamous and share nest-building, incubating, and chick rearing duties.

IUCN Status : Least Concern
