- Sense-Organs susceptible to Pressure
All are formed on essentially the same plan; a fibrous capsule invests a group of epithelial cells amongst which a nerve ramifies. The simplest form is known as a Grandry’s corpuscle-a nerve ending in one or two plates between two or three epithelial cells. These organs are found in great numbers in the bills of aquatic birds. If a duck is watched whilst it is gobbling mud at the margin of a pond, it will be seen to have a remarkable capacity for discriminating between the shells of small snails, which it can crush, and stones, which it needs to drop from its bill. Its bill is also provided with small Pacinian corpuscles. - Sepsis violacea; puparium and adult

The Sheep-ox or Muscus-ox , the Oemingarok der Eskimos ( Ovibos moschatus ), miraculously combines in itself the characteristics of the Cattle and of the Sheep; it is therefore necessary for us to consider him as a representative of a separate subfamily. - Sheep-shearing operations in Australia

- Skylark, and young ones
The fact that many young birds which are quite helpless are now reared in nurseries on the ground, as in the case of young skylarks, is a fact of interest; for it shows that the parents have chosen this nesting site comparatively recently, and are of course unable to lay large eggs, which shall produce active young, like young chickens, at will. They have acquired the habit, so to speak, of laying small eggs, and cannot alter it by changing their nesting-place. - Slate-colored Junco
Slate-colored Junco The sparrow-size Slate-colored Junco or the “snowbird,” as he frequently is called, is only a winter visitor in most areas. But what a welcome guest he is! The white belly and outer tail feathers add distinctive marks to his slate-gray plumage. The bill is pinkish white. Females and immature birds are duller and sometimes show a pinkish-brown tinge on their backs and sides. Juncos can be found around weed patches, hedges or sheltered corners of fields, where they spend much time in feeding on weed or grass seeds which provide their winter diet. Even fallen seeds are not overlooked for these birds do much of their feeding on the ground. They sleep in evergreens, sheds or other protected areas which shelter them from the cold and snow. They often visit feeders for small seeds provided by bird lovers. Their notes are hard to describe but have a musical smacking or clinking note or series of notes which once learned, are easily remembered. Their song is a series of chipping notes much like those of a Chipping Sparrow, but with more variation and more of a musical quality. This song is heard when the first warm days of spring arrive. They nest in either mountainous or northern regions for they enjoy cool climates. - Sleeping Bat

Snow Goose This medium-size goose is the most abundant member of the family and can be identified by white plumage and black wing tips. He is often called “wavy,” in the northern part of his range, while southern hunters refer to him as a “white brant.” His Latin name describes him as “a goose beyond the north wind.” We see him only as a migrant, either going to nesting grounds in Northern Canada or returning to his winter home on the coast of Louisiana and Texas. A somewhat larger relative known as the Greater Snow Goose, nests in Northern Greenland and winters along our Atlantic coast. This bird feeds on roots and bulbs of water plants found in his wintering area. Grasses, grains or other vegetation bring huge flocks where they can be seen grazing like tame geese. Feeding flocks are not welcome to the wheat grower who has fields near lakes which are used as resting places for migrating birds. - Snowy Egret
Leucophoyx thula Like ghosts from a bloody past, Snowy Egrets have returned to add their beauty to American bird life. Woman’s vanity and man’s desire for money once brought these beautiful herons almost to the point of extinction. The dainty recurved plumes, which formed a part of the breeding plumage of the birds, were known as “cross aigrettes,” when they were sold by milliners. Women bought, men slaughtered, and egrets died, not only for the plumes; but the nestlings starved after the adults were killed. Plume hunters have departed and the birds are now found in their favorite swamps. This bird has a length of 20 to 25 inches, white with black bill and legs. The feet are yellow, giving it the nickname of “the bird with the golden slippers.” The young of the Little Blue Heron are also white but have greenish legs, while the bill is 2-tone, blue with black tip. The American Egret is much larger and shows a yellow bill. - Soldier on horse

- Song Sparrow
Song Sparrow Song Sparrows literally sang themselves into a name, for few birds sing so persistently. To Thoreau these birds seemed to say: “Maids! maids! maids! hang up your teakettle-ettle-ettle.” To you it may sound differently, but you still will hear the sharp notes with which he starts his song. These are on the same pitch with a slight pause between each note. From there, the song is variable and may contain trills or assorted notes on various pitches. One bird may produce several different songs. These birds prefer brushy or weedy areas near water but may nest near your home if a bird bath is handy. No other bird seems to take as much pleasure from bathing. - Sparrow Hawk
Sparrow Hawk This little falcon, about the size of a Robin, is also known as Kestrel. Calling him a Sparrow-hawk is misleading, for insects and spiders, along with a generous portion of mice, go to make up his daily fare. Grasshoppers seem to be a special delicacy. Like other birds, he feeds on whatever is available. In cities, this includes English Sparrows. The smallest of the hawk family can be found along highways where he uses telephone poles, wires or dead trees, while scanning the fields and fence rows for prey. Dressed in colorful plumage with spotted breast, slate-blue wings, red-brown back and tail, with head showing 2 black lines and a dot, he easily is seen and readily identified. The female is slightly larger, shows more banding on the tail and lacks the blue wings, hers being browner. - Speckled horse

Spectacled snake - Spiny Hermione ( Hermione hystrix )
One of the most common species in the Mediterranean. These Worms have a very graceful, glistening appearance, after being rinsed from the dirt, which usually covers their bodies in large quantities, by repeated rinsing. However, the beautiful Hermione's thorns are more fearful than those of the Porcupine ( Hystrix), there barbs hold them back in the skin with which they come into contact. Predatory fish do not care much about these weapons. - Spiny Spider
In the specimen on the tree trunk, the spider field is seen protruding like a glittering black nodule in the middle of the transversely wrinkled underside of the bright blood-red abdomen, which, in addition to the 2 long, curved thorns at the rear corners, bears 2 pairs of shorter spines, which as the spots on the back are black. The front part of the body is hairy and glossy black. - Spotted Sandpiper
Spotted Sandpiper Any pond, lake or stream will be visited sooner or later by these little sandpipers. You find them teetering along shores, picking up insects and small crustacea which form the diet. Mud banks, sandy shores, pebbly mountain streams, half-sunken logs, all furnish happy hunting grounds. The teetering tail is distinctive and no other sandpiper has the round black spots on his breast and none has the fluttering flight. They seem to tip-toe thru the air with very short wingbeats. Young and adults in winter plumage do not show the spots but continue to teeter. They often show a white spot just above the bend of the wing when in this plumage. Their usual note is a 2-tone “peet-weet,” which it utters when flushed from its feeding ground. - Spotted Silver Tabby

This was already felt by the Greeks, to whom we borrowed the scientific name of the Squirrel. - Stages in the Life-history of Hæmocera danæ, One of the Monstrillidæ
- Starling
Starling Previous to 1890, this bird was unknown in America. Then a few pairs were released in New York City and now look at them! Starlings are everywhere. When walking around your yard or field he appears to be black with a short tail, pointed wings and a sharp pointed beak which is yellow in summer and brownish-black in winter. On closer inspection you will find that he is a little smaller than a Robin, greenish with speckled plumage in fall and winter, which develops into greenish-purple in spring. In flight he flaps and sails much like a Meadowlark but his short tail and wing pattern are distinctive. The young are brownish with lighter throats. Many of the Starling’s feeding habits are beneficial for he eats many worms and insects which he finds by turning over leaves or probing with his sharp bill. The fact that he likes fruit on occasion is not in his favor for he likes to travel in flocks and it takes a lot of fruit to feed a flock of Starlings. - Sting of a honey bee

Study of a cat from nature - Summer Tanager
Summer Tanager The rosy red plumage of the male Summer Tanager is helpful in identification for he is smaller than the Cardinal and lacks the tuft and black face patch of the latter. Females, which resemble orioles, do not have the sharply pointed bill of the oriole and are richer colored than the female Scarlet Tanager, being almost an orange-yellow below. She is olive-yellow above with no wing bars. The wings are greener than those of her near relative. Young males often show a mottled pattern of reds and yellows before attaining the rosy red hue of the adult. They prefer a rather open forest such as is found on hillsides. A dead treetop makes an ideal perch while singing or catching insects on the wing. The song is a rather melodious series of notes which reminds one of a Robin. Alarm notes are a distinctive series of chippy-tuk-tuk notes. These birds feed rather deliberately thru the trees and destroy many insects and leaf-eating larvae which they encounter. Their nest is usually far out on the limb and at least 10 feet above the ground. They spend winters in South and Central America. The breeding range does not extend as far north as that of the Scarlet Tanager. - Superficial veins of the head and neck

In the case of the thoroughly aquatic Surinam Toad (Pipa), the male helps to press the eggs, perhaps a hundred in number, on to the back of the female, where each sinks into a pocket of skin with a little lid. By and by fully formed young toads jump out of the pockets.
