- 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. - 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. - Skull of Bear (Ursus), showing the dentition

Sepsis violacea; puparium and adult - 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. - Section through a venom gland of Latrodectus 13-guttatus showing the peritoneal, muscular and epithelial layers

Sea crab - Screech Owl
Screech Owl The Screech Owl is the smallest of the eared owls, about robin size. In fact he often nests in holes built by larger woodpeckers such as flickers. Like other owls, he hunts at night when his quavering call blends with the murmur of the night breeze. Mice, shrews, beetles, moths, crayfish, frogs and small birds seem to furnish a well-rounded diet. These small owls have 2 distinct color phases, one a rich brown, the other a soft gray. Both blend with the bark of trees thus giving them protection. This is one of the mysteries of the bird world. Just why do these owls wear different colors? Both colors are often found in the same brood. Even tho small, they give a good account of themselves and soon let you know when they have young in the vicinity. The parents defend their young against all comers and often surprise innocent persons who may stroll too close to the young only to be attacked by the irate parents. - Scotch Colley, or Shepherds Dog
The Scotch breed, or colley, is a light and active one, probably the best adapted for those portions of our own country where there is no danger from wild animals. It is pretty extensively diffused in the United States and British America, and is very useful to the farmer, shepherd or drover. - Scheltopoesik

The Ruff ( Machetes or Pavoncella pugnax ) may be regarded as a long-legged Strandlooper, the only representative of his family. The beak is as long as the head (but shorter than the barrel), straight, at the tip slightly lowered and not broadened, soft all along its length, the foot is high and slender, the lower leg naked well above the hocks; of the three fronts, the middle one is connected to the outer by a tension fleece; the short, high back toe does not touch the ground; the wings are of medium length and pointed; the tail is short, composed of 12 feathers, slightly rounded at the tip. - Ruddy Duck
Oxyura jamaicensis This little duck is known by almost 100 different names in the areas where he is found. But no matter what you call him or where you find him, he is distinctive. No other duck except the Masked Duck, which is found in the West Indies, has the stiff tail which often is carried erect and fanned like a miniature sail. The male has a black or blackish-brown crown and nape, depending on the season, whether breeding or winter. The bright-blue bill, rich reddish-chestnut body and white cheek patch make the male a beautiful bird in breeding plumage. In winger the male assumes the grayish-brown coloring of the female, both showing the light cheek patch with darker crown and nape. The head, neck and feet are large for so small a bird. - Ruby-throated Hummingbird
Ruby-throated Hummingbird This, the smallest bird found in the area, can be confused only with large moths such as the sphinx or hawk moths. Both the moths and hummingbirds like to feed on deep-throated flowers such as honeysuckles, petunias and trumpet-vines but the moths prefer late evening or early morning while the hummer never passes up a chance to explore such flowers with his long brush-like tongue with which he gathers nectar. This combined with small insects and spiders goes to make up his diet. Brightly colored phials filled with sugar water will attract him to your yard. Hummingbirds are among the best fliers of the bird world and can hover, fly backward or forward or straight away, whatever meets their fancy. The male has a green back and in some lights the throat patch looks black only to flash ruby red when the bird changes position so the light is reflected. The female is duller and has white feather tips on the tail. - Ruby-crowned Kinglet
Ruby-crowned Kinglet When you hear this bird sing, you are impressed by the beauty of clear, but variable notes. When you check the source, you are surprised to see a tiny bird with such a big voice. His short tail might lead you to believe he is even smaller than the 3¾ to 4½ inches which he measures. His coloring is not impressive, being an olive-gray. You might notice the distinct eye ring or the prominent wing bars. If he is excited by your close inspection, he might flash the ruby crown feathers, from which he gets his name. - Rose
Take Damask Roses, clip off the white of them, and take six ounces of them to every pint of faire water, first well boyled and scummed, let them stand so as abovesaid, twelve hours, as you doe in the Syrupe of Violets, wringing out the Roses and putting in new eight times, then wringing out the last put in onely the juice of four ounces of Roses, so make it up as before, if you will put in Rubarb, take to every two drams, slice it, string it on a thred, hang it within the pot after the first shifting, and let it infuse within your Roses: Some use to boyle the Rubarb in the Syrupe, but it is dangerous, the Syrupe purgeth Choller and Melancholly. - Rooster

Robin There is no reason to tell you this bird is robin-size except that we would like you to remember he is 10 inches long. This helps when making a comparison with other birds. This medium-size member of the thrush family makes himself at home on your lawn, in your garden, pastures or fields. There you will see his reddish breast, dark head and back, all distinctive in sunlight or shadow. Yes, you can spot a Robin anywhere. The young have spotted breasts which is typical of the thrush family. Robins are early risers and start singing as soon as the first faint glow shows the approach of a new day. Robins do most of their feeding on the ground. There you will see them making a short run, then stop, look and listen. They seem to be able to hear their prey, for you will notice them digging worms and insects from depths which would make them impossible to see. These birds sometimes add small snakes, minnows or frogs to their diet of worms, insects and fruit. Hackberries, persimmons and red cedar seeds help carry them thru the winter. Robins often winter rather far north and are one of the first migrants to make an appearance in spring. - Ringed Plover, and young ones
When young birds live in the open, as on shingly beaches, then their down is mottled. How perfectly this harmonises with the surrounding stones only those who have tried to find young terns, or young ringed plover, for example, can tell. - Ring-billed Gull
Larus delawarensis Audubon, in 1840, referred to this species as the common American gull, but due to the change in habitat and increase in population, these birds have departed from many of their former nesting areas. However, next to the larger Herring Gull, it still is one of the most widely distributed. These birds form breeding colonies on islands in Northern United States and Southern Canada, often sharing these sites with the Cormorant and the Common Tern. Like other gulls, they are not to be trusted around unprotected nests of other species, for eggs are considered quite a delicacy in a gull’s diet. The black ring near the end of this bird’s bill is not a good field mark unless you are near or use powerful glasses to check the specimen. It looks much like a Herring Gull, except for the smaller size (18-20 inches), as compared with the 23-26 inches of the Herring Gull. The Ring-billed shows greenish-yellow legs, whereas the Herring has flesh-colored ones. Both birds show
