About the beginning of May the Herring Gulls collect into great

flocks for the purpose of reproducing, and betake themselves to large

sand-bars or mud-flats at low water, where their cacklings may be

heard at a great distance. With the aid of a glass you may see them

going through their courtships; the males swell their throats, walk

about proudly, throw their heads upwards, and emit their love notes.

These general meetings take place at all hours of the day, according

to the state of the tide, and continue for about a fortnight, when

they all depart and betake themselves to the islands on which they

breed. Several of these are situated near the one mentioned, and there

is one near Cape Sable, a few miles from the most southern point of

Nova Scotia, on which we saw thousands alighted on the trees as we

were sailing along that coast on our way to Labrador. Some individuals

begin to lay about the 19th of May or a few days earlier, while others

have not finished the process until the middle of June. During this

period they resort at certain hours to bare rocky islets, on which

they copulate. At White Head Island, while we were seated on the edge

of a beautiful sand-bar eating our dinner, we saw, on one of these

rocks, a vast number forming as it were a dense mass, which covered

about half an acre. At twelve o’clock, we observed that all those

which were not sitting on their eggs, flew over us and alighted on

the sea, about half a mile from the shore, where they remained upwards

of an hour, swimming gracefully but in silence all the while. A seal

happening to raise its head above the water frightened them, and

all raised their wings as if about to fly. Soon after they rose all

at once, separated, and went off in search of food, but returned in

less than an hour to the island, flying high and cackling loudly. A

little before sunset all those unoccupied with incubation went off

to the same rocky islands to roost, flying in silence, and mostly in

files. It was curious to observe that, whenever a large flock made

towards the sea cackling, all the ducks about immediately flew off to

a considerable distance, as if afraid of them; and we saw that these

Gulls, although timorous in the presence of man, shew great courage

in attacking predatory birds, such as Jays, Crows, Ravens, and even

Hawks, which they pursued and forced into the deep woods, or drove

away from the vicinity of their nests.

Shy and wary nearly in as great a degree as the Black-backed Gull,

they were with difficulty obtained, unless we approached them under

cover. The least noise made them instantly leave their perch, and

although there were six of us, each furnished with a good gun, and

some sufficiently expert, not more than a dozen were killed that

day, and all of them while flying. The moment one started, it would

sound an alarm, on which hundreds would rise and sail over us, at

such a height that it was useless to shoot at them. Now and then,

one accidentally passing low over the woods, was brought down. While

returning in the evening we shot one at a great height, having merely

broken the tip of its wing. Having caught it, we placed it on the

narrow path, on which it ran before us nearly to the house of the

Governor, as Captain FRANKLAND is called. It offered no resistance,

but bit severely, and now and then lay down to rest for a few moments.

It ran fast enough to keep several yards before us, cackling all the

while, and once suddenly made off from the path at a rapid rate.

Their flight is as strong as that of the Great Black-backed Gull,

but more buoyant as well as graceful. During the love season their

aërial evolutions are extremely beautiful; they pass through the air

in wide circlings, at a great height, and then come down in curious

zigzags until near the tops of the trees, or the surface of the

sea. While in pursuit of fish, they dart in curved lines with great

rapidity, frequently wheeling suddenly when over their prey, and

falling towards it. When travelling, they pass indifferently over the

land or the water, but generally at a considerable height. Their food

consists principally of herrings, of which they destroy great numbers,

following the shoals. They also feed on other fishes of small size,

shrimps, crabs, and shell-fish, as well as on young birds and small

quadrupeds, and suck all the eggs they can find. The rocky shores of

the islands on which I found them breeding are covered with multitudes

of sea-urchins, having short greenish spines, which give them the

semblance of a ball of moss. At low water the Herring Gulls frequently

devour these animals, thrusting their bill through the shell, and

sucking its contents. They also take up shells in the air, and drop

them on the rocks to break them. We saw one that had met with a very

hard mussel, take it up and drop it three times in succession, before

it succeeded in breaking it, and I was much pleased to see the bird

let it fall each succeeding time from a greater height than before.

They seem to go out to sea in search of food at particular periods,

setting out at the first ebb and returning to the shore as the tide

rises.

The young are at first fed chiefly with shrimps and other small

crustacea, which are picked up from the mud-bars or along the shores.

They are then of a deep rusty colour all over, and when fully feathered

they retain a good deal of that hue, but the feathers are edged with

light grey or brown; the feet and legs are of a greenish-blue colour,

inclining to purple; the bill dusky or nearly black. In spring they

acquire their full size, but still retain the grey and rusty plumage.

The next year they shew much light ash-grey and white about the

head, neck, and lower parts, the orange spot appears on the bill,

the feet and legs are flesh-coloured, the tail still partially banded

towards the extremity. At this age, however, I believe they breed, as

I observed some coloured in the manner described, mated with older

birds. The third spring they acquire the colouring represented in

the plate.

I found no other species breeding on the same islands. Old and young

associate together all the year round, excepting during the breeding

season, when the latter separate and pursue their avocations together.

The cry or cackling of this species, which is heard at a considerable

distance, may be imitated by pronouncing the syllables _hac_, _hac_,

_hac_, _cah_, _cah_, _cah_.

The Herring Gull has a greater range of migration along our coast and

in the interior than any other American species. I have found it on

our great lakes, and on the Ohio, Missouri and Mississippi, down to

the Gulf of Mexico, during the autumnal months, and in winter along

the shores of the latter, and all our eastern coasts. It may be said

to be resident in the United States, as it breeds from off Boston to

Eastport in Maine; but the greater number go farther north. We found

the nests of some on the bare rocks of the Seal Islands off Labrador,

but not on the coast itself. They were composed of dry plants and moss

brought from the mainland. The birds kept by themselves, and appeared

to be completely mastered by the Great Black-backed Gulls. On our

return we saw old and young on the northern coast of Newfoundland,

and on the different bays over which we passed.

I have represented an adult male, but not one of the largest, and a

young bird shot in winter, which I have placed on a bunch of Racoon

oysters, where it was standing when shot.

the United States, p. 360.

LARUS ARGENTATOIDES, _Ibidem_.

Adult Male in spring. Plate CCXCI. Fig. 1.

Bill shorter than the head, robust, compressed, higher near the

end than at the base. Upper mandible with the dorsal line nearly

straight at the base, declinate and arched towards the end, the

ridge convex, the sides slightly convex, the edges sharp, inflected,

arcuato-declinate towards the end, the tip rather obtuse. Nasal

groove rather long and narrow; nostril in its fore part, lateral,

longitudinal, linear oblong, wider anteriorly, pervious. Lower mandible

with the angle long and narrow, the outline of the crura curved, the

dorsal line beyond the prominence slightly concave, the sides erect

and nearly flat, the edges sharp and inflected.

Head rather large, oblong, narrowed anteriorly. Neck of moderate

length, strong. Body full. Feet of moderate length, rather slender;

tibia bare below; tarsus somewhat compressed, covered anteriorly with

numerous scutella, laterally with angular scales, behind with numerous

small rectangular scales; hind toe very small and elevated, the fore

toes of moderate length, rather slender, the fourth longer than the

second, the third longest, all scutellate above, and connected by

reticulated entire membranes, the lateral toes margined externally

with a thick narrow membrane. Claws small, slightly arched, depressed,

rounded, that of the middle toe with an expanded thin inner margin.

The plumage in general is close, full, elastic, very soft and blended,

on the back rather compact. Wings very long, broad, acute, the first

and second quills nearly equal, the rest of the primaries rather

rapidly graduated; secondaries broad and rounded, the inner narrower.

Tail of moderate length, even, of twelve rounded feathers.

Bill gamboge-yellow, with a large orange-red patch inclining to carmine

towards the end of the lower mandible. Edges of eyelids gamboge; iris

silvery white. Feet flesh-coloured; claws brownish-black. The head,

neck, lower parts, rump and tail, are pure white; the back and wings

pearl-grey or light bluish-grey, very slightly tinged with purple;

the edges of the wing and the extremities of all the quills, are

white. The first six quills are brownish-black towards the end, that

colour including the outer webs and the greater part of the inner of

the two first, and on the rest gradually diminishing, so as on the

sixth merely to form a bar; first quill with a patch of white about

an inch and a half long on both webs near the end; second with a

circular white patch on the inner web, the tips of all white.

Length to end of tail 23 inches, to end of wings 24-1/2, to end of claws

21-1/2; extent of wings 53; wing from flexure 18; tail 7-1/4; bill along

the ridge 2-1/2, along the edge of lower mandible 3; its depth at the

angle 3/4; tarsus 2-1/2; middle toe 2-1/4, its claw (4-1/2)/12. Weight

Young in November. Plate CCXCI. Fig. 2.

Bill brownish-black, paler at the base of the lower mandible. Edges

of eyelids greenish-grey; iris hazel. Feet purplish flesh-colour;

claws brownish-black. The general colour of the whole plumage is

light purplish-grey, the upper part of the head darker, the lower

parts minutely mottled with pale yellowish-grey; the feathers of the

upper parts, and the upper tail-coverts, irregularly edged and barred

with greyish-white. Primary quills greyish-brown, their inner webs

paler, their tips whitish; tail of the same colour, its base and outer

edge of lower mandible 2-1/2; tarsus 2-1/4; middle toe 2, its claw

(4-1/2)/12. Weight 22 oz.

From the examination of individuals of this species, it would appear

that little reliance can be placed on the markings of the quills as

affording a specific character. Four undoubted specimens of _Larus

argentatus_ now before me, have a white spot, varying in length from

one to two inches, and including both webs, near the end of the _first_

quill. One has no spot on the _second_ quill; another has a spot on

both webs of the _second_ quill of one wing, and a smaller spot on

part of the inner web of the same quill of the other wing; the third

has a very small spot on part of the inner web of the same quill of

both wings; the fourth has a large circular spot on the inner web of

that quill also in both wings.

THE CRESTED GREBE.

_PODICEPS CRISTATUS_, LATH.

PLATE CCXCII. MALE AND FEMALE.

This beautiful species returns from its northern places of residence,

and passes over the Western Country, about the beginning of September.

A few remain on the lower parts of the Ohio, on the Mississippi,

and the lakes in their neighbourhood, but the greater number proceed

towards the Mexican territories. They pass swiftly through the air,

at a height of about a hundred yards, in flocks of from seven or

eight to fifty or more, proceeding in a loose body, and propelling

themselves by continued flappings, their necks and feet stretched out

to their full length. I have observed them thus passing in autumn,

for several years in succession, over different parts of the Ohio, at

all hours of the day. On such occasions I could readily distinguish

the old from the young, the former being in many instances still

adorned with their summer head-dress. I never saw this species near

the sea-coast, where, on the contrary, I have met with the Red-necked

Grebe.

When about to alight on the water, these birds glide swiftly downward,

with their wings half-closed, and produce a sound not unlike that of

a hawk stooping towards its prey. Their velocity is so great at this

moment, that on alighting, they glide on the surface of the water

for twenty or thirty yards, leaving a furrow in their wake. In a

few moments they are all engaged in washing and cleaning themselves,

after which they dive in pursuit of the fishes on which they feed,

and which they secure by following them in the manner of Divers and

Cormorants. They are exceedingly quick-sighted, and frequently elude

by diving the shot intended for their destruction, seldom after being

chased raising more than their bill above the water, but rarely making

for the shore unless when nearly exhausted.

When in ponds, they may easily be caught with fishing hooks placed

on lines near the bottom; but if the lines are not closely attended

to, or held from a place of concealment, where you may feel that

they are hooked, and at once haul them out, the birds drown in a very

short time. On catching two or three in this manner, I found the pond

deserted the following morning and for several days after. They very

rarely fly in your presence, and they leave the ponds at night. If

forced to rise on wing, they run paddling on the water for several

yards before they rise, and fly several times round a pond of thirty

or forty yards before they attain the level of the tree-tops, for

they never fly through the woods. When once high in the air, they

move in a direct course and with speed, towards some other pond or

the nearest river. I do not remember to have ever met with a bird

of this species on a narrow creek or bayou, or on muddy waters; and

on the Ohio’s rising I have observed that they abandon the river and

betake themselves to the clear ponds of the interior.

By the 1st of October, scarcely any difference can be perceived between

the young and the old birds with respect to plumage, only the latter

have the under surface of the wings still dashed with the reddish

colour of the summer dress. I am not able to say from observation

how long the young are in attaining maturity; but European writers

assert that they take three or four years. When these birds leave

the southern waters about the beginning of April, the old already

shew their summer head-dress, but seldom have it so perfect as is

represented in the plate.

The food of this species consists of fishes, aquatic insects, and

small reptiles, together with the seeds of water plants. Dr RICHARDSON

states that these birds are abundant in all the secluded lakes of

the mountainous districts of the fur countries, and adds that their

nests are formed of a large quantity of grass, placed among reeds

and carices, and rise and fall with the water. Mr YARRELL has kindly

furnished me with specimens of the eggs, which are generally four,

measure two inches and a quarter in length by one inch and a half,

have an oval form, and a smooth surface, of a uniform yellowish-white

colour.

The following account of the digestive organs of this species was

taken from an adult male.

The œsophagus is nine and a half inches long; at its commencement,

and for an inch and a half, it has a diameter of half an inch, for

the next two inches only two-twelfths, towards the lower extremity

four-twelfths; this, however, in the contracted state, the specimen

having been kept in spirits. The mucous coat is raised into numerous

longitudinal folds.

The walls of the proventriculus are extremely thick, the glands

cylindrical, generally about a quarter of an inch long, and one-twelfth

in diameter. The stomach is roundish, compressed, the muscular coat

very thick, being that of a true gizzard, the tendons nearly half

an inch in diameter; the inner coat thick, the cuticular lining very

thick and rugous.

Between the orifice of the œsophagus and the pylorus is a rounded lobe,

from the lower part of which the intestine comes off. The pylorus

has no valve, but a thick marginal rim. The intestine, immediately

after its commencement, dilates to the diameter of half an inch, and

continues of that size for twelve inches, then gradually contracts

for about six inches, when its diameter is four-twelfths, and again

within six inches of the cœca becomes enlarged. The cœca come off at

the distance of two inches from the anus, and are an inch and a half

in length, a little enlarged towards their extremity, and rounded. The

rectum is half an inch in diameter, the cloaca one inch. The entire

length of the intestine is forty-two inches.

The heart is conical, rather pointed, and slightly curved. The trachea

is flattened, of uniform diameter, the rings complete, 167 in number,

its transverse diameter two inches and half a twelfth, contracted at

the bifurcation to two-twelfths.

The tail of the Grebes is usually described as a small tuft of

feathers; but on carefully removing the coverts and downy parts,

the tail may be satisfactorily traced. In this species there are 14

feathers, on each side 7 arranged in a semicircular manner. The two

middle feathers are separated to the distance of about 2/12, and the

two outer or lateral approach each other below, leaving an interval

of about the same space. When the feathers are broken across near

their bases, which they frequently are, there is thus produced the

appearance of a small circular tuft. When perfect, they are about 1-1/2

inches long, arched, with loose barbs, downy at their extremities.

THE LARGE-BILLED PUFFIN.

_MORMON GLACIALIS_, LEACH.

PLATE CCXCIII. MALE.

Although my learned friend Prince CHARLES BONAPARTE says in his

Synopsis of the Birds of the United States, that this species is not

uncommon in winter on our coast, I have only once met with it, and

even then I rather supposed than was actually certain that the birds

observed were Large-billed Puffins. They occurred on the outer side

of the Island of Grand Manan, at the entrance of the Bay of Fundy.

None were seen by myself or my companions on our way to Labrador, or

in that country, so that I am unable to say any thing respecting the

habits of this remarkable bird. The specimens from which my figures

were taken were kindly lent to me by Mr GOULD of London, whose name

must be familiar to you as a successful cultivator of Ornithology.
