Eurasian Wryneck (Jynx torquilla)
(17 cm.) White eye line over brown eye
line; grayish-brown head and back; heavily barred whitish underparts; often
twists neck from side to side.
The Eurasian Wryneck is perhaps the oddest
bird in China .
The bird gets its name from its habit of twisting its neck from side to side
when it is alarmed. It has a bizarre, even alien air about it. The bird is a
member of the woodpecker family, “picidae,” but it does not behave much like a
woodpecker at all. It seems to be more the avian equivalent of an anteater,
that odd, strangely shaped mammal that eats ants exclusively and laps them up
with a long, sticky tongue.
Most woodpeckers conform to a standard mode
of behavior that consists of climbing around on the trunk of a tree and probing
for insects that can be found in the bark. If none can be found, drill holes in
the tree and extract the insects that way. The wryneck rejects this established
behavior and chooses instead to hunt on the ground for its favorite food, ants,
in a most un-woodpecker-like manner.
The Eurasian Wryneck is another
semi-cosmopolitan bird species that can be found in Europe and Asia and in
winter, in Africa . In China , the Eurasian Wryneck can be found in the
northeast during summer, through the Central East Coast
during spring and fall and in the Southeast in winter.
If a female Eurasian Wryneck is disturbed
while at its nest, it will engage in its head-twisting behavior while making
with loud hissing noises. This odd behavior was noticed by some in Europe who practiced witchcraft and the bird was often
used in rituals. Part of the bird’s Latin name, “jynx,” means to put an evil
spell on someone, more often spelled “jinx,” in English.
Like other woodpeckers, the Eurasian
Wryneck nests in the cavity of a tree. This species, lacking the powerful bill
and adaptations for drilling that other woodpeckers possess, will not make its
own hole, instead it will find abandoned cavities left by other woodpeckers.
The Eurasian Wryneck’s appearance is just
as strange as its curious habits. It looks unlike any other bird and its long
heavily barred and mottled body gives it a rather reptilian look. For all its
strangeness, this species must be appreciated its uniqueness, for it is truly
just one of a kind.

Dusky Thrush (Turdus eunomos)
(25 cm.) Heavily-patterned black and white;
reddish-brown wing linings; broad reddish-brown wing patch.
The Dusky Thrush is a member of a large
family of sweet-singing songbirds, the thrushes, of the family, “Turdidae.”
Thrushes throughout the world are considered among the most gifted of avian
singers for their beautiful, rich flute-like warblings. Many thrush species in China
are also gifted musical performers, with the Song Thrush as perhaps the most
gifted of the clan.
The Dusky Thrush is also quite musical,
performing its simple whistled song many times from the time it sets off on its
spring migration north through the breeding season in mid- summer.
Thrushes and other species of songbirds
sing not only to attract a mate, but also to set up territories during the
annual summer breeding season. Each pair of birds of a particular species needs
several square kilometers of space in a particular location from which they
build nests and have exclusive food-gathering rights. The maintenance of strict
territories ensures that chicks raised by parent birds of a particular species
will have access to the necessary food resources for their survival.
The Dusky Thrush’s song is less often heard
in China ,
however, as its breeding range is in the Far North of Russia. This bird seeks
out grassy fields, pastures, and similar open country with scattered trees as
its preferred habitat. The female lays 3-5 eggs in a rather messy-looking nest.
Following the breeding season, Dusky
Thrushes will migrate south and spend the winters in Central and Southern China
and Southeast Asia . It is during the winter
that the Chinese observer will most often have the opportunity to glimpse this
handsome bird in city parks. This bird is quite common and can be readily found
in southeast China
during the winter months.
The Dusky Thrush is another versatile
omnivore that is fond of insects, especially mosquitoes, and berries.

Common Stonechat (Saxicola maurus)
(14 cm.) Male: Black head; dark brown back;
white patches on neck and wings; whitish rump; brown breast. Female: Duller
than male; no black; light brown under parts; white patch on wing
The Common Stonechat, also known as the
Siberian Stonechat, is a bird that has been recently reclassified by
ornithologists and placed in a new family. Once considered a thrush, it has been
now placed in the family, Muscicapidae, the family of flycatchers. Several
sub-species of this bird can be found in Europe and Asia .
The bird derives its name from its voice
which has been likened to the sound of two stones being struck together. This
species is strict insectivore, like other members of the flycatcher family. It
prefers open scrubby habitat where it can find low bushes in which it likes to
perch and wait for its insect prey.
The Common Stonechat has a wide breeding
range which covers most of temperate Asia . In China ,
its breeding range includes the northeast and central parts of the country. It
generally only inhabits the East Coast of the country during its spring and
fall migrations.
This bird seems particularly averse to cool
temperatures and its northern breeding range and departs these regions as early
as possible to avoid the rapid drop in temperature that can happen at these
latitudes in early fall. Stonechats which breed in warmer regions usually do
not migrate. If the breeding site of a Common Stonechat is warm come fall and
winter, there will likely be no southward movement.

Dollarbird (Eurystomus orientalis) Sanbaoniao
(30 cm.) Large, slightly hooked red bill;
large head; bluish-green plumage; light patches in wings seen in flight
The Dollarbird, also known as the Oriental
Dollarbird, is a member of the roller family, “Coraciiformes,” and is the only
member of this family of birds that can be found in East
China . The Dollarbird gets its name from the blue spots seen in
its wings during flight. The spots look vaguely like coins of money.
The Dollarbird is a large attractive
species of roller with green and blue plumage and a large red bill. The bill of
young birds is dark and gradually becomes red with age. The large red bill is
somewhat hooked, giving it a slight resemblance to a bird of prey. The
Dollarbird is often attacked by small songbirds that mistake it for a predatory
bird.
This species is found throughout Eastern China during the summer breeding season. While it
is a widespread species, it is in no place a common bird, so the sighting of a
Dollarbird is always an occasion to be celebrated and savored.
The Dollarbird will often be first seen as
it perches, flycatcher-style, in the exposed branch of a dead tree, waiting for
insects to fly by. This species is a strict insectivore, and as such it must
migrate to warm climates in the winter where a steady supply of insects is
assured.
The Dollarbird is migratory only in the
parts of its range that become cold in winter and will not support insect life.
In the warmer parts of its range, the Dollarbird will set up year-round
residence.

Common Moorhen (Gallinula chloropus)
(31 cm.) Black; red frontal shield; short
bill; line of white streaks across flanks; two white patches under tail
The Common Moorhen is an unmistakable member
of the rail family, “Rallidae.” It is a large species of rail, and it is far
more conspicuous than many members of its family. Rails are generally skulking
birds of swamps which hide deep within tall stands of reeds. The Common Moorhen
makes its presence far more obvious by noisily walking on pond and swamp
vegetation or swimming out in open water like a duck. The bird gets its name
from the old English word, “moor” which means marsh or swamp. In
This species is very attractive in its
uniformly slate black plumage with white streaks on its flanks. The legs and
feet of the bird are yellow. The bill is green with a red base that extends up
the bird’s face to form a noticeable and odd-looking frontal shield. The
species displays a persistent habit of flicking its tail.
The bird is another extremely widespread
and common species that is found throughout most of the world. It is not found
in polar regions, or throughout much of the tropics. Throughout its range, this species lives in
lakes, ponds, and swamps which offer ample open water.
The Common Moorhen is another omnivorous
species that will consume a large variety of foods. It feeds on various aquatic
vegetation and aquatic creatures.
This species will generally breed in early
spring in most of its breeding range. The female moorhen builds a basket-like
nest on the ground among the thick vegetation and lays around 8 eggs. Both
parents share the duties of incubating the eggs and the feeding of young chicks
after hatching.

Common Cuckoo (Cuculus canorus)
(32 cm.) Upperparts grey with black tail;
black bars in white abdomen; yellow iris; unbarred rump
The Common Cuckoo is a member of a notorious
family of the birds, “Cuculidae,” the cuckoos. Cuckoos also have an order named
after them, “Cuculiformes,” which includes roadrunners, anis and coucals. Their
position in an order other than Passeriformes means that despite a similar
appearance, cuckoos are not considered “songbirds”.
All species of cuckoos derive their names
from the call of the male Common Cuckoo which is heard during summer in the
Common Cuckoo’s breeding range. During the summer breeding period, this species
utters a loud and clear “kuk-oo” refrain from the treetops. The name “cuckoo”
in English, is an excellent example of onomatopoeia being applied in the name
of a bird.
Cuckoos of all species have earned their
notorious reputations due to their practice of “brood parasitism.” The females
of cuckoo species do not make nests nor possess any desire to raise their own
chicks. Instead, they lay their eggs in the nests of other, usually smaller,
birds and in so doing force their parental duties on them. Female cuckoos do so
by visiting nests, pushing an egg out of those nests, and leaving one of their own.
They will visit many nests and repeat the process. The Common Cuckoo is
particular about which species it will victimize with its parasitic behavior,
preferring to inconvenience the females of the reed warbler group.
In addition to their shirking of parental
responsibilities, cuckoos’ reputations have been further sullied by their
occasion habit of eating the eggs and chicks of other bird species.
Also known at times as the Eurasian Cuckoo,
the Common Cuckoo breeds in Europe and Asia, and can be found in winter in
Africa and Southeast Asia . In China ,
it breeds in every part of the country except the western desert regions where
it is never seen. It prefers to live in open wooded areas.
In addition to the occasional egg and chick
the Common Cuckoo’s diet consists of insects, particularly species of hairy
caterpillars which other birds avoid. It would be considered an insectivore as
it rarely eats food from other sources.
Although the Common Cuckoo does possess
some habits that we might describe as despicable, this bird is nonetheless an
interesting creature which although common, is rarely seen.
