Birds sentence examples The small birds were singing softly. Notice has next to be taken of a Memoir on the Employment of Sternal Characters in establishing Natural Families among Birds, which was read by De Blainville before the Academy of Sciences of Paris in 1815, 5 but not published in full for more than five years later (Journal de physique. They fly hither and thither in my thought like blind birds beating the air with ineffectual wings. Some types of cuckoos take only 10 days. In birds, this stalk consists entirely of blood-vessels, which in the adult enclose no terminal vesicle, and fuse with the membranous linings of the skull. The treatise of Kessler on the osteology of birds' feet, published in the Bulletin of the Moscow Society of Naturalists for 1841, next. The baby bird grows inside the egg, and after a few weeks hatches (breaks out of the egg). Members of the kingfisher family are expert at this type of flying. Those where the song is partly inherited, but the bird tunes it in by copying others. They assist in the extremely rapid and vigorous ventilation of the lungs, the latter being capable of but very limited expansion and contraction in birds. The most important result is the proof that, until the end of the Cretaceous epoch, most, if not all, birds were still possessed of teeth. The sound came again, the cry of someone who was hurt. A bird Many small birds take 2–4 weeks to hatch eggs.
Not indeed altogether so homogeneous as the Nearctic area, it presents, however, even at its extreme points, no very striking difference between the bulk of its birds. Fledgling may also have different calls from adults. Birds live all over the world. The ruffed grouse (or "partridge") is the most common of game birds, but woodcock, ducks and geese are quite common. All birds have, like most reptiles, a well-developed third lid or "nictitating membrane," which moves from the inner canthus obliquely upwards and backwards over the cornea. This leads us to think that feathers evolved first as heat insulation and only later for flight. Unlike mammals, birds only have one opening as the exit hole for body fluids, and for reproduction. Of the birds of bright plumage the humming-bird and the cardinal-the scarlet, the yellow and the white-are the most attractive. E Here, as over so large a portion of the Australian region, we find birds constituting the supreme class - the scarcity of mammals being accounted for in some measure as a normal effect of insularity. Camouflage colours help to hide the bird, and bright colours identify the bird to others of the same species. Fossil Birds Much had naturally been expected from the study of fossil birds, but, so far as the making of classifications is concerned, they have proved rather a source of perplexities. The Triballi are described as a wild and warlike people (Isocrates, Panathenaicus, 227), and in Aristophanes (Birds, 1565-1693) a Triballian is introduced as a specimen of an uncivilized barbarian. Between 1831 and 1834 the same author brought out, in continuation of his Centurie, his Illustrations de zoologie with sixty plates, twenty of which represent birds. Mercerat, who proposed for them the name of Stereornithes, a new order of birds, mostly gigantic in size, and said to combine the characters of Anseres, Herodiones and Accipitres. 4. Some birds do not fly. Birds (Aves) are a group of vertebrates which evolved from dinosaurs. Small towns, children playing, birds singing. A wandering albatross can sleep while flying. [2] More recent estimates, using a new way of calibrating molecular clocks, showed that modern birds originated early in the Upper Cretaceous. Some birds, like those of the bird of paradise in Papua New Guinea have such beautiful feathers that they have been hunted for them. The class Aves is now defined as all the descendants of the most recent common ancestor of modern birds and Archaeopteryx lithographica.[13].
The seventy plates (forty-six of which represent birds) composing, with some explanatory letterpress, the volume, are by C. Cousens and H. Though a comparatively small number of species of birds are figured in this magnificent work (seventeen only in the first series, and twenty-two in the second), it must be mentioned here, for their likenesses are so admirably executed as to place it in regard to ornithological portraiture at the head of all others. Partridges, woodcock, snipe, &c., are among the game-birds; but all kinds of small birds are also shot for food, and their number is thus kept down, while many members of the migratory species are caught by traps in the foothills on the south side of the Alps, especially near the Lake of Como, on their passage. Haswell, " Notes on the Anatomy of Birds," Proc. Katie wiped her eyes. It's the early bird that catches the worm. For birds that eat grain and fruit, the parents eat and partly digest the food for the babies. A good example of this is the currawong. Although birds are warm-blooded creatures like mammals, they do not give birth to live young. The most extraordinary feature is unquestionably the former existence of the gigantic Dinornithes or moas and, another family of Ratitae, the weird-looking kiwis or Apteryges, which are totally unlike any other existing birds. The term " lumbar " vertebrae is inapplicable to birds. The large broad wings of a vulture allow it to soar without flapping. The avifauna of this region is very rich; it includes all the forest and garden birds known in W. Europe, as well as a very great variety of aquatic birds. That Garrod has so very much advanced the classification of birds is ultimately due to his comprehensive anatomical knowledge and general insight. Currawongs from some areas sing much more complex songs than others. In this work birds generally were grouped in two great divisions - " land-fowl " and "water-fowl" - the former being subdivided into those which have a crooked beak and talons, and those which have a straighter bill and claws, while the latter was separated into those which frequent waters and watery places, and those that swim in the water - each subdivision being further broken up into many :sections, to the whole of which a key was given. Nowadays people sometimes race them for sport. Of the metatarsals the fifth occurs as an embryonic vestige near the joint; the first is reduced to its distal portion, and is, with the hallux, shoved on to the inner and posterior side of the foot, at least in the majority of birds. During all this time little had been done in studying the internal structure of birds; 3 but the foundations of the science of embryology had been laid by the investigations into the development of the chick by the great Harvey. 8vo, 1838-1843), forming part of his Naturalist's Library; and Gould's Birds of Great Britain has been already mentioned.
Penguin's flippers are good for swimming. Most birds have an extended period of parental care after hatching. Birds which are originally immigrants from North America: Podicipedidae, with the flightless Centropelma on Lake Titicaca;. Robins will make a beautiful little round nest of woven grass and carefully line it with feathers, bits of fluff and other soft things.
Guillemots lay their eggs on rock shelves with no nest at all. 6. Time is a bird for ever on the wing. At the same time, their direct competitors, the pterosaurs, dwindled in numbers and variety, and became extinct at the end of the Mesozoic. Nevertheless he makes some attempt at a systematic arrangement of birds, which, according to his lights, is far from despicable. Brehm has published a list of Spanish birds (Allgem. Baptornis, another of Marsh's genera, seems to be allied to Enaliornis, Palaeotringa and Talmatornis, were by him referred to Limicoline and Passerine birds. People can catch some bird diseases, for example: psittacosis, salmonellosis, campylobacteriosis, Newcastle's disease, mycobacteriosis, influenza, giardiasis and cryptosporiadiosis. Later many groups evolved with reduced wings, such as ratites, penguins and many island species of birds. of birds, and he seems to have been the first to institute a direct comparison of their skeleton with that of man; but in this respect he only anticipated by a few years the more precise researches of Volcher Coiter, a Frisian, who in 1573 and 1575 published at Nuremberg two treatises, in one of which the internal structure of birds in general is very creditably described, while in the other the osteology and myology of certain forms is given in considerable detail, and illustrated by carefully drawn figures. On reviewing the progress of ornithology since the end of the 18th century, the first thing that will strike us is the fact that general works, though still undertaken, have become proportionally fewer, while special works, whether relating to the ornithic portion of the fauna of any particular country, or limited to certain groups of birds - works to which the name of " Monograph " has become wholly restricted - have become far more numerous. A bird built a nest in the flower box and it has little baby birds! Both these works (now rare) are manifestly framed on the Linnaean method, so far as it had then reached; but in their arrangement of the various forms of birds they differed greatly from that which they designed to supplant, and they deservedly obtained little success. Thus it has come to pass that the muscles of the hind limbs are, like their framework, more easily compared with those of reptiles and mammals than are the wings, whilst within the class of birds they show an enormous amount of variation in direct correlation with their manifold requirements. Bird like chickens that feed mainly on the ground and only use their wings to fly to safety have small wings. New Zealand has also yielded many flightless birds, notably the numerous species and genera of Dinornithidae, some of which survived into the 19th century; Pseudapteryx allied to the Kiwi; Cnemiornis, a big, flightless goose; Aptornis and Notornis, flightless rails; and Harpagornis, a truly gigantic bird of prey with tremendous wings and talons. One of the most peculiar of these is the genus Phasianus, of which splendid birds all the species are restricted in their wild state to northern Asia. [15], From Simple English Wikipedia, the free encyclopedia. Migrating water birds usually form family groups of 12-30 birds. The only known groups without wings are the extinct moa and elephant birds. At the very beginning of the year 1832 Cuvier laid before the Academy of Sciences of Paris a memoir on the progress of ossifi cation in the sternum of birds, of which memoir an cuvier abstract will be found in the Annales des sciences and naturelles (xxv. Highly specialized air-sacs are characteristic of all birds. This cannot apparently be done for insects or foi birds; Newton accordingly unites the two into the Holarctic region. The idea of what is a suitable place differs between species, but most build bird nests. The opening is called the cloaca. This method is used by birds of prey such as falcons that are looking for something to eat. He obtains a magic glass cage, yoked with eight griffins, flies through the clouds, and, thanks to enchanters who know the language of birds, gets information as to their manners and customs, and ultimately receives their submission. The same year which saw the promulgation of the crude scheme just described, as well as the publication of the final researches of Muller, witnessed also another attempt at the classification of birds, much more limited indeed in scope, but, so far as it went, regarded by most ornithologists of the time as almost final in its operation. Earliest in date as it is greatest in bulk stands Audubon's Birds of America in four volumes, containing four hundred and thirty-five plates, of which the first part appeared in London in 1827 and the last in 1838. to Audubon's great work in two volumes, on the same scale - The New and Hitherto unfigured Species of the Birds of North America, containing life-size figures of all those which had been added to its fauna since the completion of the former. The fossil record shows that birds evolved from feathered theropod dinosaurs.
