~ BREEDING
The red-breasted merganser is a type of duck known as a sawbill. The serrated edges on its long, thin bill make it ideal for grasping small, slippery fish. This birds liking for salmon has brought it into conflict with anglers, but despite some persecution its populations are not seriously threatened. In North America, it is the most numerous merganser species, with a population of almost 250,000.
~ HABITAT In winter the red-breasted merganser lives in a flock that usually numbers 20 to 30 birds but sometimes up to a thousand. At this time of year, the flocks are found in coastal areas. The birds prefer sheltered, shallow bays, estuaries, and inlets with clear waters and plenty of suitable banks where they can rest. In summer many red-breasted mergansers stay in their coastal habitats, but others move inland to breed near clear lakes
The male red-breasted merganser tries to attract a mate with a series of displays, including the "curtsy." In this display, he dips his neck, raises his back out of the water, and then points his tail down. The male also chases females and rivals across the water. After pairing up, the birds stay together only to mate. The male usually leaves when the female begins incubating. The female finds a nest site among dense vegetation, with grass, brambles, or heather for cover. The approach to the nest is often a tunnel through thick
plant growth. The bird may also nest among tree roots or boulders or in an old rabbit burrow. The nest is a shallow dent in the ground lined with grass, leaves, and the female's down. She lays 8 to 11 eggs, which she covers with down when away from the nest. The ducklings can find their own food soon after hatching but are watched very closely by their mother. Broods often join together when the females begin to leave the young on their own. Often one female is left to watch several sets of young.
Left: In the breeding season, the female red-breasted merganser watches for courting males.
Right: After a dive, the duck may rise up from the surface to shake water off its wings.
DID YOU KNOW? • One red-breasted merganser was recorded flying at a speed of about 37 miles per hour over Alaska. • The red-breasted merganser has a variety of nicknames. It is called the spring sheldrake or sea robin in the United States, the popping wigeon or beldrake in Ireland, and the her-
aid or earl duck in Scotland. ct In 1898 a red-breasted merganser became the first duck to be banded. The experiment helped to establish banding as a method for tracking birds. • The red-breasted merganser eats large quantities of fish. A duckling eats over 45 pounds in its first three months of life.
BIRDWATCH The red-breasted merganser usually lives in small flocks in the winter. The birds are easy to spot in their coastal habitats. In the summer the bird breeds in boreal forests and in swampy tundra, usually near the coast but also on inland
lakes and rivers. The very well hidden nest is obvious only when the ducklings appear. The red-breasted merganser is not noisy. In the breeding season the female utters a rasping call, and the male responds with a catlike call.
~ FOOD &: FEEDING or rivers. The migrating birds tend to settle in the band of coniferous forest that runs around the lands south of the Arctic Circle. There they find dense vegetation for nesting and watery habitats for feeding. In summer, as in winter, they are sociable birds, nesting in colonies. After breeding, the migrating populations come back to their winter quarters on the coasts. Separate flocks mix quite freely during the winter months.
The red-breasted merganser feeds mainly on fish. In fresh waters it favors salmon, sticklebacks, pike, and eels. In coastal waters it eats herring, flounder, sand eels, and gobies. It also feeds on aquatic insect larvae, crabs, and shrimps, as well as the seeds, leaves, and roots of underwater plants. The duck dips its head below Left: Primarily coastal, the redbreasted merganser favors sheltered areas, where it dives for fish.
the water's surface to look for food, then dives quickly and propels itself through the water with its wings and feet. It can stay submerged for up to two minutes, but it usually surfaces in half a minute. It often feeds in a small group, moving across the water in a line to force fish into the shallows and then diving for them. It generally brings food to the surface to eat and, like many fish-eating birds, takes a sip of water after eating.

~ BREEDING
The snow bunting is named both for its extreme northerly breeding grounds and for its predominately snow-white breeding plumage. During the winter months, the bird usually moves south to more temperate regions in Europe, Asia, and North America. At that time the snow bunting can sometimes be spotted in the United States along the coasts as well as on inland hills and fields.
~ HABITAT
The snow bunting lives as well as breeds on the northernmost coasts of North America, Asia, and Europe and on islands in the Arctic. Its breeding range stretches south to Labrador. This bird inhabits tundra and rocky coasts in addition

to bare mountaintops and outcrops in glaciers, usually at elevations over 3,000 feet. In the extreme north of its range, it also lives at sea level. In winter it flies south to grassy coastal areas, sand dunes, and open inland fields.
BIRDWATCH
During the mating season, the adult male snow bunting is almost unmistakable in flight. His breeding plumage appears to be almost entirely white.
The male snow bunting displays his bold black-and-white coloring when the breeding season begins in May. He struts away from the female with his wing and tail feathers spread . Then he turns and runs back toward her and repeats the ritual. He also sings a flutelike tune, either in flight or on the ground. The female builds a nest of dead grasses, stalks, moss, and
ter, when it visits the northern states and southern Canada. It is easiest to spot on the coasts but may also be seen inland . This bird almost never perches in trees, preferring to run or to hop across the ground.
The snow bunting eats seeds, grasses, buds, and insects. In summer, air currents carry insects as far as the Arctic snow fields, where they are stranded as well as paralyzed by the cold. Snow buntings spot the insects against the white snow and pick them off easily. Young birds eat almost nothing but insects. Large winter flocks feed on seeds and grains in fields . The snow buntings "leapfrog" over one another as the flock moves forward. Sometimes the birds comb beaches for food.

At the beginning of May, the male merlin performs display flights. He slowly circles high in the air to attract a mate. When a female enters his territory, the two birds fly high, then swoop down together and chase each other. The pair bond lasts only for a single season, but the two birds may winter together. The pair looks for a suitable nest site on the ground or occasionally on a cliff ledge near a large open area. The nest is a bare hollow, which is lined with grass if the soil is sandy. Sometimes a pair uses the tree nest of a large bird such as a crow. The female usually lays five or Left: The male does most of the hunting, but the female feeds the chicks at the nest.
six eggs at two-day intervals. She does most of the incubating and relies on her mate to bring her food. The chicks hatch in about a month. At first the female broods the chicks, covering them with her wings while her mate hunts for food. In a single day he usually brings three to six kills to the nest. They are frequently young waders or small birds such as the meadow pipit. When the chicks have all their feathers at 1 8 days, the female begins to leave the nest to hunt. By the time the offspring are a month old, they are able to fly out from the nest to take food from their parents. But they remain nearby for another month until completely independent.

~ HABITS The oil bird inhabits deep mountain caves in Panama, northern South America, and on Trinidad's northern coast. Up to 50 pairs nest in the pitch-black depths. They shun light, waiting until dusk to leave their cave. The oilbird is well adapted to its dark environment. It moves skillfully through the crowded cave on its long wings, and its large eyes give it keen night vision. It cannot see in total darkness, however. Some nests are 2,600 feet from the cave's entrance-the only source of light. In these depths, the bird navi-
gates by echolocation, emitting high-pitched clicking sounds as it flies. The sound waves bounce off cave walls and stalactites, as well as other birds. The echoes then help the oilbird judge its distance from these objects. The bird's clicks become more frequent as it nears an object, providing an accurate idea of the object's location The clicking in oilbird caves is audible to humans. If a human enters or if the beam of a flashlight penetrates the darkness, the cave erupts with the shrieking calls of frightened birds.

The pin-tailed sandgrouse, for example, forms large groups that move very slowly across newly planted fields, eating seeds. This species is found in the western Mediterranean, North Africa, and central Asia. If water is scarce, sandgrouse
There are 16 species of sandgrouse, and all cope very well with the often harsh conditions of their habitats. By nesting out in the open, where most animals cannot endure the heat these birds are able to avoid many predators. Sandgrouse have a number of other remarkable survival tactics. One example is the ingenious way in which the male carries water to his offspring over distances of many miles.
~ HABITS Sandgrouse are found in Africa, Asia, and southern Europe. These hardy birds can survive in difficult conditions. Many species inhabit arid regions, but the Tibetan sandgrouse lives in a cold climate at 10,000 to 20,000 feet, and the Malagasy sandgrouse dwells in hilly green areas. Sandgrouse are fast fliers and may cover 50 miles in a day to find food. They are also highly sociable, often roosting and flying in large groups. Some spe-
can go without drinking for up to five days. When water is available, they gather in flocks of 20 to over a thousand birds and fly to drinking sites. A flock generally lands a few yards from the edge of the watering hole. The birds wait for a minute or two, taking off at the slightest noise. If there is no sign of danger, they run to the water and drink, immersing their bills to eye level and sucking up the water. After drinking, a bird may wait to leave with its flock or fly back alone to its roost or feeding ground.

pied flycatcher has benefited a great deal from the provision of birdhouses. Often a lack of tree holes for nesting keeps this bird from colonizing a wooded area. Breeding density in regions with birdhouses can be twice that of areas without them .
~ FOOD &: FEED ING The pied flycatcher catches flies, beetles, butterflies, and other flying insects in midair. It supplements this diet with grubs
and worms from the ground. It also hovers to pick insects from foliage or clings briefly to trees to take insects from the bark.
Male pied flycatchers return to the breeding grounds in spring, often to the nest holes that they used the previous year. The females arrive several days later. Each male defends a small territory around his nest hole. He sings, often from a high perch, to proclaim ownership and attract a mate. The male usually has one mate, but he occasionally has two or even three. After the female has built her nest and begun incubating, the male may court another female at another nest site. But after she lays her eggs, he abandons her and returns to his first mate to help raise the chicks. By moving up to two miles away from his
first nest site, the male may be able to deceive the second female into believing that he is unmated. Many males try this strategy, but most fail and have just one mate. The broods that hatch early are more successful than later ones. This is because the young eat mainly caterpillars, which become scarce as the season progresses. The average clutch size also declines later in the season, since the female does not waste energy hatching chicks that she will be unable to feed . In an attempt to lessen feeding visits, the nestlings are often fed prey that is larger than what the adults eat.
Left: The agile pied flycatcher can hover near foliage to snatch larvae.
Right: Pied flycatcher parents may feed their chicks 30 times an hour.
DID YOU KNOW? • The ranges of the collared and pied flycatchers overlap in eastern Europe. The two species interbreed, and hybrid birds form up to 10 percent of the combined population.
• The male pied flycatcher sings from late April to June. Before pairing, he may sing over 3,000 times in one day. After finding a mate, he sings only about 1,000 times a day.

~ M IGRATION
Pied flycatchers migrate across southwestern Europe to winter in sub-Saharan Africa. Many of them settle in the moist coastal forests of the Gulf of Guinea. Because of their roundabout migration route, some eastern populations fly westward for over 1,500 miles before turning south for Africa. For most birds, the stopover area is in northern Portugal. There they devour berries and other food for about a Left: The pied flycatcher often nests in an abandoned woodpecker hole.

month to acquire adequate reserves to sustain them on their long journey. To obtain enough food, they may defend feeding territories. From Portugal, the birds fly without stopping across the Mediterranean and the Sahara, taking just a few days to reach their winter quarters. On the return trip in spring, pied flycatchers take a quicker route, flying farther to the east. This enables them to arrive early at the breeding grounds in order to find the best nest sites.

~ BREEDING
In the past, when farmers cut their fields by hand, the corn croke was quite common in European meadows. The bird found ideal nesting sites in hay fields, which were not cut down until late summer. Today, however, the corn croke is
a victim of modern farming practices. Grass is cut earlier in the year to be stored as fodder, and the birds have no escape from the blades of modern mowers.
weeks. She feeds her chicks for three or four days, after which they find their own food. They stay with her for another month or so until they can fly. The young are very vulnerable in their first weeks, as farmers move in from the edges of fields with mowing and harvesting machines. Left with no escape routes, the chicks fall victim to the machines. Unwilling to abandon her offspring, the female is often killed too.
Left: The male corn crake repeats his noisy mating call day and night for hours at a time.
Right: At one day old, the chick is

DID YOU KNOW? • The male corn crake may emerge from cover to investigate the presence of a nearby rival, so bird-watchers try to lure the bird out by making a sound that is much like the male's call. To make this sound they rub a stick over a notched piece of wood . • Prior to the decline of the
corn crake population, the birds occasionally appeared in eastern North America during the fall migration. The last corn crake on record in this area was discovered on Long Island in 1963. • The corn crake's scientific name, (rex crex, sounds like the male's characteristic call.

BIRDWATCH
The corn crake spends spring and summer in northern Europe and central Asia and migrates to Africa in fall. In flight, it can be identified by chestnut patches on its wings. Unlike other crakes, which frequent marshes, the corn
crake is most often found in meadows. But because of its secretive nature and nocturnal habits, the bird is rarely seen . During the mating season, however, the male's repetitive, raucous" crek-crek" call can often be heard.
~ FOOD &: FEEDING
~ HABITS The corn crake usually lives in meadows and grasslands but sometimes frequents marshes and farmland as well. It is active after sunset, occasionally until dawn. The solitary, reclusive corn crake is rarely seen in the open. It creeps about in tall grass, bent low on its long legs and with its head stooped below the level of its tail. From time to time, it cranes its neck above the grass to look around or call noisily. The bird takes to the air only when absolutely necessary. If disturbed, it may fly slowly for
In spring the male corn crake tries to attract a mate. With his head stretched up, he repeatedly utters a very loud, rasping "crek-crek" call. When a female comes near, the male displays by strutting and showing off his chestnut wing patches. He may also give her a gift like a worm or snail. The female nests alone in tall grasses or occasionally in cornfields. She lays up to 14 eggs, which hatch after about two
several yards with its legs dangling, then drop back into the grass. But, instead of flying, the corn crake prefers to run from danger. It sounds more like a scurrying rat than a bird as it rushes through the grass. In fall, the corn crake leaves its European breeding grounds and migrates to Africa. On these migration flights, it flies strongly, with its legs almost horizontal. By mid-April, it has returned to its breeding grounds. Right: The corn crake is the only
crake that lives mainly in grassland rather than marshes.
Grassy meadows and farmland provide the corn crake with an abundant supply of seeds and grain, which the bird picks up with its stubby bill. The corn crake also eats insects and their larvae as well as other small invertebrates. These include slugs, millipedes, snails, earthworms, and spiders. Like many seed-eating birds that inhabit fields and meadows, the corn crake has suffered from insecticides. These chemicals kill off the bird's insect prey and coat crop seeds with a poisonous film.

The crested lark feeds primarilyon the ground. It digs in the soil with its long bill to extract beetles, grasshoppers, caterpillars, and ants. It also catches dragonflies and flies in the air, then removes their wings before devouring them. In addition, the bird eats spiders, snails, and small worms, as well as seeds, seedlings, buds,
flowers, grain, and leaves. During the winter it eats fewer insects and a greater number of seeds, especially grass seeds. The crested lark employs its conical bill as a hammer to soften the tough, protective shells of some insects before it eats them.

The crested lark pairs for life. In spring the male displays to the female . He puffs out his chest, cocks and fans his tail, and holds his crest erect while flapping his wings and singing loudly. Meanwhile the female crouches, with her crest raised and tail fanned. The female makes a nest, lining a ground scrape with grass. She may add a dome for shelter, using the lower branches of a bush. She incubates the three to five eggs for 11 to 13 days, taking breaks to feed and preen. Instead of returning directly to the nest, she lands some distance away and looks around first. While the female sits on the nest, the male sings from a low
perch and watches for danger. If disturbed, the female may abandon her eggs or chicks. But she lays a replacement clutch later. The hatchlings are blind and covered in straw-colored down. Both parents answer their offsprings' cheeping calls for food by supplying them with insects, especially caterpillars. Some of the young may die because the parents tend to give the most food to the offspring that opens its mouth widest. The young can leave the nest at about nine days old, but the parents feed them until they can fly at about three weeks. When threatened, the young crouch flat or hide in the grass.
