BIOLOGY LIBRARY G FLAMMAM. PRINTED BY TAYLOR AND FRANCIS, RED LION COUBT 3 FLEET STKEET. . PJIEFACE. THIS volume is the third of the series belonging to the ' Fauna of British India ' that has been published in the course of the present year. Of the two preceding volumes, containing the ' Fishes/ the first appeared in July and the second in September. Birds, which form the subject of the present volume, and which it is proposed to complete in two more, are not only the most familiar and, in many respects, the most interesting class of the Vertebrata, but they are in India represented by the largest number of known species. The hope expressed, in the Introduction to the ' Mammalia ' of the present series, that Mr. Gates would undertake the ' Birds/ has been fulfilled, and I think that Indian orni- thologists are to be congratulated on the fact. Had not Mr. Gates come from India and devoted his furlough to the task, much delay would have been caused and the work, in all likelihood, much less completely executed,, as I should a2 5b2 IV PREFACE. probably have been compelled to write the greater part, if not the whole, myself. The number of species of birds to be described in the three volumes, of which this is the first, exceeds those enumerated in Jerdon's ' Birds of India ' by more than one-half, chiefly because Jerdon omitted the species inhabiting Ceylon, Sind west of the Indus, the Western Punj ab, Hazara, the Upper Indus valley north and north-west of Kashmir, Assam, Burma and the intermediate countries (such as the Garo, Khasi, and Naga hills, Chittagong, Sylhet, Cachar, and Manipur), together with the Andaman and Nicobar Islands, all of which are comprised within the limits of British India as accepted in the present publication. A large number of additional species have also been recorded, since Jerdon' s work was published, from Sind, the Punjab, the North-western Pro- vinces, Rajputana, and the Western Himalayas, the fauna of all of which has become better known within the last 25 years. The additional species from the Peninsula are far less numerous. No branch of Zoology has, in India, attracted so much attention or enlisted the services of so many observers as Ornithology ; and there is probably no division of Indian biological science, not even Botany, on which so much has been written and of which our present knowledge is so far advanced. Far more is known about the nomenclature, distribution, and habits of birds than about those of mammals, reptiles, or fishes. Within the last ten years some good local faunas have been written, foremost amongst these being Legge's ' Birds of Ceylon ' and Oates's ' Birds of Burmah.' A periodical work with the somewhat eccentric title of ' Stray Feathers/ devoted entirely to Ornithology, flourished for several years under the energetic guidance of Mr. Allan Hume, and within the last 18 months a valuable addition has PREFACE. V been made to the volumes already published. But, above all, Mr. Hume brought together, chiefly in about ten years (from 1872 to 1882), a collection of Indian birds from all parts of the country far superior to any ever before accumulated ; indeed it is doubtful whether an equally complete collection has ever before been made, from a similar area, in any branch of Zoology or Botany. The whole of this collection, amounting to 60,000 skins, besides a very large number of nests and eggs, has now been presented by Mr. Hume to the British Museum ; and as the same building contains the collections of Colonel Sykes, the Marquis of Tweeddale (Viscount Walden), Mr. Gould, and, above all, of Mr. Hodgson, the opportunities now offered for the study of Indian birds in London are far superior to those that have ever been presented to students in India. Every facility has been afforded to Mr. Gates by the officers of the British Museum for studying the superb series of Indian birds now in the National Collection. It must be left to naturalists in India to judge how far Mr. Gates has succeeded in accomplishing the task that he has undertaken. This task, though greatly facilitated by the collected specimens and information, is still far from easy ; for, in works like the present, it is not sufficient to have access to the necessary data, the facts known require to be so arranged as to be easily understood and available for ready reference. If the present work complies with these conditions, it is to be hoped that the study of Ornithology not only in India, but throughout the Oriental Regiou, may benefit as much as it unquestionably did by the appearance of Jerdon's ( Birds of India/ In one respect the volume now published falls short of the work just named. The limits assigned to the number and size of the volumes in the ' Fauna of British India/ limits yi PEEFACE. in the necessity for which, much as I regret their existence, I am obliged to concur have precluded the addition of any save the very briefest notes on habits, migration, folk-lore, and other interesting points, the inclusion of which in Jerdon's work added so greatly to its attraction. On the other hand, the classification adopted by Jerdon was obsolete even when he wrote, and was in many respects inferior to that employed by Blyth, thirteen years previously, in his ' Catalogue of the Birds in the Museum of the Asiatic Society ' (Calcutta) . Unfortunately this faulty classification of Jerdon's has become so closely associated with the Indian Ornithology of the last quarter of a century, partly from the general use of Jerdon's work as a text-book, partly from the employment of his serial numbers, with interpolated additions, in all Mr. Hume's writings, that many Indian ornithologists are probably unacquainted with the important additions to our knowledge of bird-classification made by Huxley, Garrod, Forbes, and other writers, and, it may be feared, will not welcome the changes that have become necessary. It may be hoped that the facilities for the determination of specimens afforded in the present work by the generic and specific keys and by the woodcuts will serve to mitigate the regrets of those who are attached to the old system of classification. The arrangement of the families of Acromyodian Passeres proposed in this volume is new, and partly based on a charac- ter of unquestionable value as evidence of relationship the plumage of the young birds. The subdivision of the Passeres has long been one of the great difficulties of ornithologists, and one who had devoted much time and thought to the subject, the late W. A. Forbes, was accustomed to say that the whole order consisted of a single family. In all proba- bility the difficulty of subdividing the order will never be completely solved, the fact being that the Passeres are a PREFACE. yii group of animals of comparatively recent geological origin, still in course of development, and that in the Passerine series no breaks have yet been established by the dying out of intermediate forms, as has taken place in orders that have survived greater geological changes. In one respect a difference may perhaps be traced between the classification employed in this volume for birds and that applied in the e Fauna of British India ' to other classes of Vertebrata. The number of genera accepted or proposed by Mr. Gates is larger in proportion than that adopted in the Mammals, Reptiles, and Fishes. Personally I should have preferred a reduction in the generic divisions of birds; but, at the same time, I regard the question as one of con- venience, there being, so far as I can see, no essential distinction between generic and specific characters. Many of the so-called " structural distinctions " in birds, such as the arrangement of the feathers at the base of the bill and the development of a crest, are probably purely ornamental, and, like the colours of the plumage, connected with sexual selection ; and I cannot see why the differences mentioned are of higher importance than colour. It is, however, only fair to say that many of the best ornithologists hold the same views as Mr. Gates. It is also only just to add that I believe this is the only detail of classification in which I see any reason for differing with him. An account of the chief writers on Indian birds up to 1862 was given by Dr. Jerdon in the Introduction to the first volume of the s Birds of India ' the principal authors enume- rated, besides Jerdon himself, were Franklin, Tickell, Sykes, McClelland, Burgess, Adams, Tytler, Kelaart, Layard, Hut- ton, Theobald, and, above all, Hodgson and Blyth, to whom, with Jerdon, may fairly be attributed the foundation of Indian ornithology. A general notice of those who had Vlll PKEFACE. principally been engaged in working out the birds of the Asiatic continent and islands was included by Mr. R. B. Sharpe in his Introduction to Gould's ' Birds of Asia/ This " Introduction " was reprinted in < The Ibis ' for 1884, p. 49. Amongst the contributions to the ornithology of India since the appearance of Jerdon's ' Birds of India ' some of the principal are: (1) Blyth's commentary on Jerdon in 'The Ibis' for 1866 and 1867, his ornithology of Ceylon (Ibis, 1867), and his posthumous list of the Birds of Burma, published, with additions by Viscount Walden, as an extra number to the Journal of the Asiatic Society of Bengal for 1875 ; (2) Jerdon's supplementary notes (Ibis, 1871 and 1872); (3) papers by the Marquis of Tweeddale (Viscount Walden), Major Wardlaw Bamsay, Colonel J. Biddulph, and Messrs. A. Anderson, H. J. Elwes, R. C. Beavan, J. Scully, and R. B. Sharpe in < The Ibis ' and the 'Proceedings' of the Zoological Society; (4) contributions by F. Stoliczka, H. H. Godwin- Austen, W. E. Brooks, V. Ball, G. King, 'A. C. McMaster, and the present writer to the Journal and Proceedings of the Asiatic Society of Bengal ; (5) Hume's ' Scrap Book,' ' Nests and Eggs,' ' Lahore to Yarkand ' (in part by Dr. Henderson), and 'Game Birds' (written in conjunction with Colonels C. H. T. and G. F. L. Marshall); (6) Legge's 'Birds of Ceylon,' Oates's ' Birds of Burmah/ J. Anderson's ' Zoological Results of the Yunnan Expeditions/ Barnes's ' Birds of Bom- bay/ Murray's ' Vertebrate Zoology of Sind ' and ' Avifauna of British India ;' and above all (7) the eleven volumes of < Stray Feathers.' Of all the pages in the latter the larger number are by Mr. Hume himself, the other more important Indian contributors being Messrs. R. M. Adam, J. Aitkeii, A. Anderson, J. Armstrong, V. Ball, H. E. Barnes, C. T. Bingham, W. E. Brooks, E. A. Butler, Cock, J. R. Cripps, J. Davidson and Wenden, W. Davison, S. B. Doig, S. B. Fairbank, J. A. Gammie, J. Inglis, W. V. Legge, C. H. T. PREFACE. IX and G. F. L. Marshall, E. W. Gates, G. Reid, J. Scully, and G. W. Vidal ; there are also some papers from European ornithologists, especially Messrs. R. B. Sharpe and J. H. Gurney. An important aid to ornithology in general has been furnished by the British Museum Catalogue of Birds, written by Messrs. R. B. Sharpe, by whom the greater part has been contributed, H. Seebohm, H. Gadow, and P. L. Sclater. Some valuable contributions to the ornithology of Burma, founded on the collections made by Mr. Fea, have lately been published by Count T. Salvadori in the ' Annali del Museo Civico, Genoa/ Hitherto the progress of Indian ornithology may be divided into two periods ; the first of which, ending with the publi- cation of Jerdon's work, was especially signalized by the labours of Hodgson, Jerdon, and Blyth, whilst in the more recent period the dominant figure has been Mr. Hume. The addition to the present work of any anatomical details beyond those that are essential for classification would involve too great a demand upon the limited space available. An excellent sketch by Prof. W. K. Parker will be found in the last (ninth) edition of the ' Encyclopaedia Britannica/ under the article " Birds" (vol. iii, p. 699). A general account of the osteology by Mr. R. Lydekker was published at the beginning of the eighth volume of ' Stray Feathers/ For more complete descriptions the student may turn to Bronn's 1 Klassen und Ordnungen des Thier-reichs ; Aves/ by Selenka and Gadow. Numerous details will also be found in papers by Garrod and Forbes in the ' Proceedings ' of the Zoological Society ; and a work in two large quarto volumes, by M. Fiirbringer, has recently been published in Amsterdam. A diagram showing the terms applied to parts of the plumage will be found on page xi. The division of the class Aves into orders will be discussed X PREFACE. by Mr. Gates in the third volume,, and a list of the works referred to in the synonymy will be added at the same time. The author will defer to the same opportunity any general remarks which he may find necessary. With the present volume half o the proposed work on the Vertebrate Fauna of British India is completed, three and a half volumes having now appeared out of seven. Of the remaining volumes, one on Reptilia and Batrachia, by Mr. G. A. Boulenger, is ready for the press, and will be the next for publication, and it is hoped that a second volume of Birds and perhaps the remaining half-volume of Mammals will also be published in the course of 1890.

Axillaries are the lengthened feathers springing from the axilla or region beneath the base of the wing. Supplementary bristles or hairs are those springing from the side of the forehead in front of the rictal bristles. Naral bristles or hairs are those springing from the front of the forehead and covering the nostrils. The measurements in this work are invariably in English inches and decimals, and are taken thus : Length. The distance from the tip of the bill to the tip of the longest tail-feather, unless otherwise stated. Tail. The distance from the root of the tail, generally indicated both in the fresh and dried state by the presence of a piece of flesh on the underside, to the tip of the longest feather. Wing. The greatest distance from the bend of the wing to the tip of the longest primary, measured straight. When the wing is curved, it is flattened out for the purpose of measurement. Tarsus. The distance from the centre of articulation of the tarsus with the tibia to the base of the middle toe. Bill. The distance from the angle of the gape to the tip, measured straight. SYSTEMATIC INDEX.

The anterior limbs are modified into wings. The skull articulates with the vertebral column by a single occipital condyle, and the jaw is connected with the skull by the interven- tion of a quadrate bone. The heart consists of four chambers, two auricles and two ventricles, and the right and left sides are completely separated from one another. There is only one aortic arch, the right. It is usual to divide all living birds into two great subclasses, which are diagnosed from each other by the shape of the sternum. In one subclass, the Carinatce, the sternum is typically provided with a keel ; in the other, the Ratitce, the keel of the sternum is absent. Although this primary division of birds is convenient in many ways, yet there are exceptions to its application which render a classification based on the shape of the sternum of doubtful utility. Some birds which from other points of view are undoubtedly Carinatce have the keel of the sternum little, if at all, developed. I prefer therefore to divide birds at once into groups which I shall term Orders, and in doing so I shall avail myself of the recent studies of Mr. Seebohm. This gentleman, partly by independent osteological investigations of his own, and partly by utilizing the discoveries of other workers in the same or similar fields, has, with- out disturbing the usually accepted classification of birds to any great degree, arrived at an arrangement which possesses the merit of being precise and clear, so far as the materials at his disposal have enabled him to be so. He has, moreover, diagnosed the different Orders by characters which the least skilful can easily investigate and discover for themselves. Mr. Seebohm divides birds into several large groups which he terms Orders, and these again into suborders which are equal to the groups which I, in accordance with the usual practice, prefer to call Orders. I do not propose to treat of the distinctions between the different Orders here, but to deal with them at the end of this work, as I gather from Mr. Seebohm that he contemplates a revi- sion of them. The period of two years which, moreover, must elapse before the present work is completed cannot fail to be pro- ductive of much additional information and improvement with respect to the classification of birds. YOL. I. B Order I. PASSERES. The deep plantar tendons passerine ; palate a?githognathous. The above two characters in combination suffice to separate a passerine bird from all others. The deep plantar tendons are the muscles which run down the leg of a bird and move the toes. There are several types or forms of these muscles. The late Professor G-arrod thus writes about them : " In birds generally, whatever the number of their toes, there are two muscles whose fleshy bellies are situated in the leg proper (that is, between the knee and the ankle), deep, and just behind the tibia. These muscles arise, one from almost the whole of the posterior surface of the tibia and from the fibula, in a bipenniform manner, and the other from the inferior surface of the horizontal femur just behind the outer genual articular condyle. The former is termed the flexor perforans digitorum pedis, because its terminal tendons perforate those of the more superficial flexors on their way to the ungual phalanges of their respective toes ; and the latter is termed the flexor longus hallucis, because there is generally a shorter muscle to the same digit. " These two muscles descend to the ankle (the joint between the tibio-tarsus and the tarso-metatarsus) side by side ; they run behind it, in the fibro-cartilagmous or osseous mass which, in birds, is always found at the posterior part of the upper end of the tarso-metatarse, in two canals, deeper than any of the other flexor tendons ; and in these canals there is always a definite relation between them. Sometimes the tendons are side by side ; and then it is always that of the flexor longus hallucis which is the external of the two, the osseous vertical ridge, which is nearly always seen in the dry bone, separating them. Sometimes, how- ever, one is superficial or, in other words, posterior to the other. When this is the case, it is always the flexor perforans digitorum which is the deeper. In the Swifts, for instance, ihe, flexor longus hallucis quite covers the flexor perforans digitorum ; but in most Parrots, as may be seen by the disposition of the osseous canals in the dry tarso-metatarse, that for the former muscle is external as well as superficial, only partially covering it. " These relations are constant, and must be always borne in mind in all attempts to identify the muscles. From these it can PASSERES. 3 be inferred, as is verified by dissection, that the tendon of the flexor longns liallucis crosses its companion superficially on its way from the ankle to its insertion in the hallux. " Just before, or just at the commencement of, the sole of the bird's foot (near the joint between the metatarsus and the phalanges) these two tendons generally split up to supply the toes." The manner in which these tendons serve the toes and their relation to each other, when combined with other characters, are of the greatest service in diagnosing the various orders of birds. The deep plantar tendons are said to be passerine when the flexor perforans digitorum serves the three front toes and the flexor longus liallucis serves the hind toe, both tendons being perfectly disconnected in such a manner that the hind toe is separately movable from the front toes. This formation is shown in the accompanying sketch : hallux ankle. . ... tarso-metatarsus. digits... Sketch showing the arrangement of the deep plantar tendons in a passerine bird. (From P. Z. S. 1875, p. 347.) The determination of the character of the deep plantar tendons in a freshly-killed bird is very easy. In a dried state the tarsus and toes must be macerated in water until soft, when the tendons can be dissected without difficulty. B2 4 PASSEBES. The palate of a bird is termed segithognathous when the vomer is broad and blunt and disconnected from, the maxillo-palatines, which are separated from each other by a considerable interval. The principal bones in the palate of a bird are shown in the accompanying sketch of the skull of a Raven, which has the palate segithognathous. may. Under view of the skull of a Raven, vo, vouier; r/ixp, roaxillo-palatine process ; pa, palatine ; ptff, pterygoid ; q, quadrate ; b.sph, basi-sphenoid ; sph.r, sphenoidal rostrum. The determination of a passerine bird, as before stated, rests on the association together of the above two characters. PASSE-RES. 5 The order Passeres contains about half the total number of living birds, or somewhat more than 6000 species. Of these nearly 1000, or one sixth of the number, are found within the limits of the Indian Empire, either as residents or as seasonal visitors. The primary division of the Passeres into two large groups is based -on the mode of attachment of the muscles of the syrinx, and may be thus expressed : Birds in which the intrinsic muscles of the syrinx are fixed to the ends of the bronchial semi- rings Acromyodi. Birds in which the intrinsic muscles of the syrinx are fixed to the middle of the bronchial semi- rings Mesomyodi. The Acromyodi have the muscles of the syrinx complex and consisting of numerous pairs. The Mesomyodi have the muscles simple, consisting in many cases of only one pair. T.i, Syrinx of a Magpie*, showing the Acroinyodian attachment of the intrinsic muscles at the ends of the bronchial semi-rings. The left-hand figure is a side view and the right-hand figure a dorsal view of the syrinx. The membranous parts between the bronchial semi-rings and the internal tympaniform mem- brane are dotted ; n, in are the second and third bronchial semi-rings ; T.i, the internal tympaniform membrane; st, the muscle from the side of the trachea to the upper end of the clavicle ; 1, 2, 3, 4, 5, 6 the syringeal muscles; there is a 7th. which is hidden by the fith ; the 4th is hidden below and between the 1st, 2nd, and 3rd. * 1 am indebted to my friend Dr. Hans Gadow for this original drawing of the syrinx of a Magpie. Syrinx of Pitta angolensis (after (lavrod, P. Z. S. 1876, pi. liii), showing the Mesomyodiau o,ttaclunent of the intrinsic muscles at the middle of tbe bron- chial semi-rings. There is only a single pair of bronchial muscles, continued down from the sides of the windpipe, insignificant in size, quite lateral, and terminating by being inserted into the middle of the outer surface of the second bronchial semi-ring. All the Passeres of the Old World belong to the Acromyodian group with the exception of three small families, viz. the Phile- pittidcK from Madagascar, the Xenicidce from New Zealand, and the Pittidoi from India, the Oriental, ./Ethiopian, and Australian regions. The Eurylcemidce, frequently associated with these Meso- myodian Passeres, I propose to elevate to the. rank of an Order. It follows from the above that all the Indian Passeres, with the exception of the Pittidce, belong to the Acromyodian group. The Mesomyodi may therefore be dismissed from further con- sideration with the remark that they are divided info I wo Croups: the Oliyomyodce, with the lower eud of the trachea unmodified ; and the Tracheophonce, with the lower end of the trachea modified to form an organ of voice. The Pittidce fall into the first group, as do also the Philepittidce and Xenicidce. The remainder of the OligomyodcB and the whole of the Tracheophonce occur only in the New World. No success has attended the efforts of anatomists to subdivide the Acromyodi into two or more groups by internal characters, and no two naturalists agree in the arrangement and extent of the families of this difficult group. In drawing up ihe annexed scheme of the families that occur in India I have endeavoured to avail myself of those characters which appear to be constant and easy of examination. A very useful character to be employed in determining the position of a bird is the number of primaries in the wing; but before this can be used with absolute precision, it is necessary to eliminate by other characters those families some of the members of which possess nine primaries and others ten. Such families are the Dicasidw and Alaudidas. PASSERES. 7 .The l)'n
