CHARADRIUS HIATICULA Linnaeus

RINGED PLOVER

_Contributed by Francis Charles Robert Jourdain_

HABITS

The ringed plover breeds both on the east and west coasts of Greenland,

ranging north to Sabine and Clavering Islands and Denmark Harbor on

the east side and to Inglefield Gulf on the west. It is also said to

breed near Cumberland Sound in Baffin Land, but this may refer to the

semipalmated plover, _Charadrius semipalmatus_, and it has occurred

casually in Barbados, Chile, and southern Alaska.

The subdivision of the ringed plover into geographical races is

attended with considerable difficulties owing to the presence of

passing migrants on many of its breeding grounds. The Siberian form,

_Charadrius hiaticula tundrae_ is generally recognized, but is only

distinguishable with certainty in summer plumage. Probably the

Alaskan specimen belongs to this race. E. Lehn Schiöler, with fine

series of carefully sexed birds before him, separates the Greenland

breeding birds from the typical race under the name of _Ch. hiaticula

septentrionalis_, but material with accurate data is too scarce in

other collections to enable us to hazard an opinion.

_Spring._--In northeast Greenland, where Manniche found this species

breeding plentifully, the birds arrived about the end of May or the

beginning of June, at the same time as the other waders. Icelandic

birds arrive early: April 22 to 28 (Faber).

Dr. W. Elmer Ekblaw says in his notes:

The ringed plover is one of the most noticeable birds of

the shorelands of northwest Greenland. Few beaches are

unoccupied by these noisy little birds, and rarely is one

out of sound of their shrill piping. They are quite as

common about the streams and pools of the interior and

along the seepage swales of the ground moraines. They come

to the land as early as May 29 and stay until the last week

in July. Almost invariably they are mated when they arrive

and only rarely does one see more than a pair together,

except where they congregate about swales or shallow pools

to feed. They are sociably inclined and do not hesitate to

make their nests near the Eskimo villages, probably feeling

more secure from Arctic foxes when near dogs and human

habitation.

_Courtship._--The courtship of this species has been well described by

Farren, Selous, and Stanford. The former (1910) says:

Ringed plovers may be seen in pairs skimming low over the

ground, circling to a far height and descending again

like a flash, almost touching the ground as they do so.

They do not follow each other, but each describes similar

evolutions, overlapping and crossing the other’s line of

flight. Their long pointed wings, showing much white, give

a fictitious impression of size and as they alight on the

ground after skimming a short distance with curved drooping

wings they seem suddenly to vanish from sight as they touch

ground; in place of the long-winged graceful flyer is a

little plump-shaped gray bird, very difficult to see as it

runs with short quick steps over the sand.

Edmund Selous (1901) also describes a male as advancing toward the

hen a few steps at a time, and moving his legs with a rapid vibratory

motion during the pauses. Stanford (1927) remarks that the courtship is

by no means easy to observe even with the aid of a powerful glass.

In one party on the beach on March 20, where at least

two males were contending for one female, the males ran

backward and forward with short, quick steps, and when

another male was near the feathers of the back and the tips

of the closed wings were elevated, the tall depressed and

spread out to its full extent to show the white tips of the

feathers, and the whole body arched with the head and neck

drawn in, the black gorget being puffed out to nearly twice

its normal size. In this crouching attitude the males ran

aimlessly to and fro for half an hour at a time, but making

no real attempt to attack each other.

Another male--

kept running in front of the hen and sinking down on the

beach every few yards exactly as if settling down on a

nest. Occasionally while brooding in this way he would

tilt himself forward onto his breast with the closed wing

tips pointing up almost vertically over his back, the tail

depressed, and the legs scratching out sand and stones

behind him. The indifference displayed by the hen to this

performance was as noticeable as it usually is in the case

of lapwings’ “rolling” on the ground. On several other

occasions in April I saw cock ringed plovers settle down

and appear to brood for several minutes exactly as if they

were on a nest; in one case the bird kept turning round

and round on one spot, and twice at least this action was

followed by an attempt at coition.

The love flight often covers nearly a mile of ground, and both birds

take part--crossing and recrossing with their bodies twisting from

side to side and soft beats of the wings. The double note, according

to Stanford, has a remarkably vibrant quality at these times and the

throat appears to be swelled out.

_Nesting._--Both nesting sites and the nests themselves of this species

vary considerably. The commonest site is among the sand and shingle

above high-water mark on the seashore. In some cases the eggs are

laid in a hollow scratched in the sand with no lining of any kind, in

others small fragments of cockle shells and small stones are collected

and imbedded, while other nests are more or less substantially built,

from a few dead bents carelessly arranged to well-made cups in which

almost any material available is utilized, such as driftwood, rabbits’

droppings, stems of leaves, and shore plants, etc. On some beaches

where there is no sand the eggs may be found lying on the bare pebbles,

while on the north Norfolk coast they are often placed under shelter of

sea heath, and nests have been met with in cornfields, several miles

from the sea, or on open grassland in sewage farms inland.

_Eggs._--Normally four in number, occasionally three on late layings,

while instances of five are rare. In color they vary from stone color

to ocherous or clay yellow sometimes with a warm tinge, spotted as a

rule rather sparingly with brownish black. Occasionally varieties with

large blotches of sepia are met with and white eggs have been recorded

as well as bluish eggs, without markings. The shell is deep green when

viewed from within. The measurements of 100 British eggs, made by the

writer, averaged 35.9 by 25.9 millimeters; the eggs showing the four

extremes measure =39= by 26.5, 37 by =28.5=, =32.2= by 25 and 32.7 by

=24= millimeters. Eggs from Iceland and other northern localities are

decidedly smaller.

_Young._--Incubation is shared by both sexes which relieve one another

at short intervals and the period is variously estimated at from 22 to

25 days; probably 24 or 25 days represents the average. The young are

hatched within 24 hours and leave the nest as soon as the down is dry.

Apparently a second brood is reared in some cases, but many of the late

nests may be second or third layings.

Doctor Ekblaw writes:

The old birds were wildly agitated whenever I approached,

and by the customary simulation of injury attempted to

lead me away from the nest. The fledglings ran about as

soon as hatched, and like all little shorebirds were quick

to respond to a warning signal and sink into pebble-like

immobility. The weather was so cold that the old birds did

not leave the young, for when the brood was separated both

parents sheltered some of the little ones.

_Plumages._--The plumages and molts are fully described in A Practical

Handbook of British Birds, edited by H. F. Witherby (1920).

_Food._--Insects, including Coleoptera (_Apion_, _Aphodius_,

_Haliplus_, _Hydroporus_, etc.), Crustacea, especially the smaller

species (Gammaridae, Amphipoda, etc.), Mollusca, chiefly small marine

univalves, such as Littorina, Annelida (earthworms), and vegetable

matter (seeds of _Polygonum_, etc.).

_Behavior._--This is an attractive and inoffensive species, sociable

in its habits and met with in flocks of considerable size out of the

breeding season, when their simultaneous maneuvers on the wing are

a very characteristic feature of the great estuaries, the flocks

appearing to change from light to dark as the upper or under surfaces

are exposed. They may also be seen on the mud flats, making short runs

at intervals, when the movements of the legs and feet are so rapid that

the eye can not follow them.

_Voice._--John T. Nichols contributes the following:

A rather clear, not very loud, low-pitched whistle, given

on the ground as much as in the air, rather infrequent.

This may be written _kruip_ or _puik_, occasionally

distinctly two syllabled and suggesting the semipalmated

plover’s call, but lower pitched. It was heard in late

September from several birds loosely associated with a

larger number of scattered dunlin on tidal sands north

of Liverpool. They usually took wing in silence, and the

species seems to be a rather silent one as seen here

and elsewhere on British shores in September. They were

very likely not traveling, and their voice therefore not

comparable with that of the semipalmated on home shores.

Also the note described is very likely not analogous with

the full, loud-flight note of the transient semipalmated

plover.

_Enemies._--During the autumn and winter months the flocks are

occasionally harried by a migrating merlin (_Falco columbarius

aesalon_), and some clutches of eggs are annually destroyed by

marauding Corvidae (crows) and Laridae (gulls). On some parts of the

coast which are much exposed, great damage is done by exceptionally

high tides, as many nests are built close to the high-water mark.

_Fall._--In Greenland Manniche (1910) observed that the old birds left

in pairs about the first week in August, as soon as the young were

grown up. The young birds immediately went to the shores and estuaries,

consorting with young sanderlings and turnstones and leaving for the

south early in September. At the Westmann Isles in south Iceland they

leave between September 20 and October 10.

_Winter._--In the British Isles the wintering birds are to be met

with in flocks on most of our larger estuaries. When on the wing they

sometimes associate with dunlin and also occasionally with redshanks.

DISTRIBUTION

_Breeding range._--In the Old World, commonly in the British Isles and

sparingly in the Faroes and Iceland; also probably on Bear Island and

a few pairs in Spitsbergen as well as on Waigatz, Kolguev, and Nova

Zembla. On the European Continent, from the Arctic Ocean south to the

Mediterranean, chiefly on the seacoasts, and only locally by lakes and

rivers. In the Mediterranean it is local on some of the islands and

nowhere plentiful. The north Asiatic race has been separated, while in

the New World its breeding range includes both coasts of Greenland and

perhaps the east coast of Baffin Land, unless the last statement is due

to confusion with the semipalmated plover.

_Winter range._--Many remain in the British Isles through the winter,

but birds from northern Europe migrate to the Mediterranean region and

Africa, where they have been recorded as far south as Cape Province and

Natal, the majority wintering south of the Sahara. The Atlantic Isles

(Canaries, Madeira, and Azores) are visited on passage, and Asiatic

birds have been recorded from the Indo-Malayan archipelago and even

Australia, though some doubt has been cast on this.

_Spring migration._--The principal passage at Gibraltar takes place in

March, the latest birds leaving in April. From about mid March to mid

April old birds are on passage northward and the breeding ground in

Norway is reached in April, and in Sweden from late March onward.

_Fall migration._--In northern Europe (Norway and Sweden) the southward

movement takes place in September and at the Straits of Gibraltar the

passage lasts from September to November. At Heligoland young birds

begin to pass as early as the end of June and the beginning of July.

_Casual records._--In Jan Mayen it apparently occurs in some numbers,

but is not known to breed. Barbados, one, Chancery Lane, September

10. Gould’s record of one from Port Stevens, Australia, is a somewhat

questionable one. One obtained at Sultanpur, south of Delhi, November,

1878; another at Gilgit, October, 1879. (These records must refer to

the Siberian race, as also probably the Chilean occurrence and that

from Sitka, Alaska.)

_Egg dates._--In northeast Greenland Manniche found eggs from June 17

to July 18, while in Nova Zembla the young were recently hatched at the

beginning of August and eggs probably laid late in June or early in

July. In the British Isles eggs have been met with in March, but most

eggs are laid from the end of April onward. April 16 to 30 (5 dates),

May 1 to 14 (10 dates), May 15 to 31 (21 dates), June 1 to 30 (23

dates), July 1 to 30 (7 dates).

CHARADRIUS DUBIUS CURONICUS Gmelin

LITTLE RINGED PLOVER

_Contributed by Francis Charles Robert Jourdain_

HABITS

The little ringed plover owes its place in the American list to a

casual occurrence at Kodiak Island, Alaska. It is noteworthy that in

J. F. von Brandt’s paper in the Journal für Ornithologie, 1891, the

Alaskan specimen is recorded as “_Charadrius alexandrinus_ Pall.” There

is also a specimen in the United States National Museum (No. 39523)

which is said to have been taken at San Francisco, but some doubt

appertains to the latter record.

_Spring._--The range of this species does not extend far to the north

in western Europe and it is only a rare straggler to the British Isles.

In northern Germany it appears in fair numbers on the larger rivers and

at lakesides, about the middle of March, but except in southern Sweden

few cross the Baltic to breed.

_Courtship._--H. F. Witherby (1919) has some interesting notes on

this species which was breeding in company with the Kentish plover

(_Charadrius alexandrinus_) near Dunkerque, in northern France.

On April 28 the little ringed plovers were flying round

after each other, with a beautiful slow, long, flap of

the wings, much like the flight of a large butterfly and

uttering a pleasing little song. This was evidently a

“courtship” action and we found many “scoops” in the sand,

but no eggs.

Liebe describes the song flight as beginning with a zigzag oblique

ascent, followed by short horizontal flights at various angles over

the gravelly bed where the hen is sitting, uttering meantime his

musical whistle, which is answered by the bird beneath, and ending

in a sharp descent in a curve toward the water’s edge and thence

with low, skimming flight to the hen. The little ring plover is a

much more demonstrative and noisy species than the ringed plover and

when its breeding haunts are approached instead of running off with

a low whistle and then flying a short distance ahead, it flies round

and round the intruder with loud repeated whistling notes. Naumann

(1887) expresses the pairing song by the words “_duh, du dull lull

lullullul_,” taken in slow time and ending with a wonderful trill only

to be heard on the breeding ground.

_Nesting._--Continental writers lay much stress on the fact that this

bird by preference always makes the nest in gravelly patches rather

than in sand. This is not invariably the case, as the bird builds

freely on sand banks in rivers where there is no shingle or gravel,

and at times also on dry mud. It may be found nesting far inland,

but nearly always in the neighborhood of water and shows a decided

preference for the shores of fresh-water lakes and the larger rivers

rather than the seashore.

_Eggs._--The normal clutch is four, though three is not an uncommon

number, and generally they are readily distinguishable from those of

the other sand plovers. They are more pyriform in shape than those of

the Kentish plover, and average less in size than either of the two

other common European species. In color the ground color is often

grayish when fresh but dries out to a yellowish stone or pale reddish

ocherous, with many fine streaks and spots of dark brown and numerous

small ashy streaks or spots. On the whole the markings are paler and

scantier than with the Kentish plover, but in rare cases large blotches

of rich brown and ash colors are found in some sets, and others show an

approach to the normal type of Kentish plover. The eggs are laid in a

mere hollow without lining in the gravel. The measurements of 100 eggs

(68 by the writer and 32 by Rey) average 29.8 by 22.08 millimeters; the

eggs showing the four extremes measure =32.8= by 23, 30.1 by =23.5=,

=27.3= by 21.1, and 28.6 by =21= millimeters.

_Young._--Incubation is said by Naumann (1887) to be apparently

performed by both sexes, but in warm and sunny weather the eggs are

left for long periods uncovered. The period is over 22 days, probably

23 or 24 (not 16 or 17 as erroneously given by Naumann). Only one brood

is reared in the season as a rule, but some dates are extremely late

and point to an occasional second brood.

_Plumages._--The plumages and molts are fully described in A Practical

Handbook of British Birds, edited by H. F. Witherby (1920).

_Food._--Definite records are scanty, but it is evident that the main

food consists of insects, including the smaller Coleoptera and their

larvae; Diptera and larvae; Neuroptera (Phryganeidae or caddis flies

and larvae). Naumann also found a small worm in one case in the stomach.

_Behavior._--Witherby (1919) writes:

The little ringed plover is even more demonstrative than

the Kentish and it is shyer and more difficult to mark onto

its nest or young. Both species have a very plaintive alarm

note which they utter constantly as they fly round the

intruder, but the Kentish is less fussy and less noisy than

the little ringed. When one is near the young both species

go through various outcries, such as running along the

ground crouching low with head stretched out, lying on the

side with one wing up, the legs stretched out and the tail

spread, or with the breast on the ground and both wings

half spread, but the performance of the Kentish is much

less abandoned than that of the little ringed.

P. W. Munn (1921) also writes:

The behavior of the birds at their nest is totally

different from Kentish plovers, which are not demonstrative

whilst they have eggs; but the little ringed plover flies

wildly round and round, twisting and doubling and uttering

its wild whistle, or else runs frantically about on the

ground, whistling plaintively.

_Enemies._--The eggs are occasionally taken by Corvidae, and the birds

themselves sometimes fall victims to Accipitres.

DISTRIBUTION

_Breeding range._--Central and southern Europe, from France, Denmark,

southern Sweden, southern Finland and 64° N. in Russia, south to the

Mediterranean and its islands and Africa north of the Sahara. In Asia

its range extends across Siberia to the Pacific and includes also

Japan. In India and the Philippines, Hainan, and Formosa it is replaced

by other subspecies. It does not breed in the British Isles, but nests

in Madeira and the Canaries.

_Winter range._--Winters in tropical Africa, south to the Gold Coast,

Fernando Po, the lower Niger, Lakes Rudolf, Albert and Victoria Nyanza,

and the Red Sea coast; in Asia to Arabia and India and also to the

Sunday Islands and perhaps New Guinea.

_Spring migration._--In south Spain it arrives about mid March and is

widely distributed in April, while in the eastern Mediterranean the

passage takes place in Crete and Corfu in April. On Heligoland it is

only a rare straggler.

_Fall migration._--The north German breeding birds leave for the south

at the end of September. Farther south the presence of immigrants from

the north among the breeding birds is seldom noted.

_Casual records._--In the British Isles there are about 10

well-authenticated records; April (2), August (4), and October (1

or 2). The supposed records from Iceland and the Faroes are not

authenticated. Gaetke only records 2 at Heligoland in 50 years.

_Egg dates._--In northern Africa eggs have been found from March

onward; in Spain and the Balearic Isles, March 16 (1 date), April 15 to

30 (3 dates), May 1 to 14 (4 dates), 15 to 30 (3 dates); late dates,

June 12 and July 11. In France and Germany, May 3 to 17 (7 dates), 18

to 31 (8 dates); June 1 to 15 (5 dates); late dates, July 19 and 22.

CHARADRIUS MELODUS Ord

PIPING PLOVER

HABITS

_Contributed by Winsor Marrett Tyler_

Wilson and Audubon were familiar with the piping plover as a common

summer resident on the sandy beaches of the Atlantic coast. Audubon

found it breeding as far north as the Magdelen Islands and wintering

abundantly on the coast of Florida.

During the years between the time of these early writers and the

present, the species has been subjected to many seasons of spring and

autumn shooting which, in the closing years of the nineteenth century,

brought the bird nearly to the point of extinction.
