PREFACE.


Circumstances have retarded the completion of the present volume, chief among which were interruption by field work (including a second visit to Costa Rica), occasional periods of illness, and the specially difficult character of some of the included groups; furthermore, one large family (the Woodpeckers, Picidæ) was worked up and even set in type, but was finally omitted because its inclusion would increase the bulk of the volume far beyond a convenient size. It will, therefore, be included in Part VI.

The Families included in this and preceding volumes are as follows:

Part I, issued October 24, 1901, included the Family Fringillidæ (Finches) alone.

Part II, issued October 16, 1902, included the Families Tanagridæ (Tanagers), Icteridæ (Troupials), Coerebidæ (Honey Creepers), and Mniotiltidæ (Wood Warblers).

Part III, published December 31, 1904, included the Motacillidæ (Wagtails and Pipits), Hirundinidæ (Swallows), Ampelidæ (Wax-wings), Ptilogonatidæ (Silky Flycatchers), Dulidæ (Palm Chats), Vireonidæ (Vireos), Laniidæ (Shrikes), Corvidæ (Crows and Jays), Paridæ (Titmice), Sittidæ (Nuthatches), Certhiidæ (Creepers), Troglodytidæ (Wrens), Cinclidæ (Dippers), Chamæidæ (Wren-Tits), and Sylviidæ (Warblers).

Part IV, issued July 1, 1907, contained the remaining groups of Oscines, namely, the Families Turdidæ (Thrushes), Zeledoniidæ (Wren-Thrushes), Mimidæ (Mockingbirds), Sturnidæ (Starlings), Ploceidæ (Weaver Birds), and Alaudidæ (Larks), together with the Haploophonæ or Oligomyodian Mesomyodi, comprising the Families Oxyruncidæ (Sharp-bills), Tyrannidæ (Tyrant Flycatchers), Pipridæ (Manakins), and Cotingidæ (Chatterers).

The present volume contains the Tracheophone Mesomyodi, represented by the Families Pteroptochidæ (Tapaculos), Formicariidæ (Antbirds), Furnariidæ (Ovenbirds), and Dendrocolaptidæ (Wood-hewers), together with the Macrochires, containing the Families Trochilidæ (Humming Birds) and Micropodidæ (Swifts), and the Heterodactylæ, represented only by the Family Trogonidæ (Trogons).

The number of species and subspecies described in the five volumes is 2,038, with 351 additional extralimital forms characterized in the "keys." About 1,150 to 1,200 forms remain to be treated in subsequent parts of the work.

Acknowledgments for the loan of specimens for use in the preparation of the present volume are due to the same individuals and public institutions as have already been named in previous volumes; also to Mr. C. H. Lankester, of Cachí, Costa Rica, who kindly placed the Tracheophones of his fine collection of Costa Rican birds at the author's service.

To Señor Don José C. Zeledón, of San José, Costa Rica, the author is specially indebted for most generous help, at considerable expense to himself, in making a very fine collection of the birds of that country, which proved of incalculable value in the preparation of this work.

Dr. C. W. Richmond, Assistant Curator, and Mr. J. H. Riley, Aid, of the Division of Birds, U. S. National Museum, have rendered invaluable assistance; Dr. Richmond through his special knowledge of ornithological bibliography and his extremely useful and very complete card catalogue of generic and specific names, made at "first hand," or directly from the publication in which each name was first published, as well as by carefully scanning the proof sheets with particular reference to correctness of citations in the synonymy; Mr. Riley, by copying references from various publications, but especially through having performed the tedious task of measuring several thousands of specimens.[1]

There has been some criticism of the present work on the ground that certain books, local lists, and other publications have not been cited in the synonymies. The omission of these is very much regretted by the author, who in explanation, if not justification, would state that it has been quite impossible for him to cover the whole field; that the literature of ornithology is so vast, and increasing so rapidly, that to bring the bibliography and synonymy of all the species up to date and keep it so would require all the time that any one individual could possibly give to it; and that since much the greater part of this labor (which has justly been termed "the drudgery of ornithology") has been done by the author himself, very largely in his own time (which means during hours which should have been given to rest or recreation), he hopes that critics may be lenient as to this shortcoming of the work.

A matter which has called forth wholly unexpected criticism is the necessarily irregular manner in which brief descriptions of nests and eggs are interspersed through the pages of this work. That the purpose of these "vague and scattered descriptions" might be misunderstood by anyone was a possibility which did not occur to the author; on the contrary, their intent seemed so self-evident that explanation was not thought of. Since, however, one writer does not "see how they can be of much use to the student of oölogy," and inquires why, "if considered of value — were they not given uniformly throughout the work," it may be stated here that these brief descriptions are given only (or at least mainly) in cases where some particular style of nest or coloration of eggs is characteristic of a group (family or genus), as a sort of accessory or supplemental group character,[2] and that the numerous instances of their omission result either from the absence of anything specially characteristic or distinctive or else (as is often the case among the tropical forms) from lack of information on the subject. Placing the accent marks to names of localities in Mexico and other parts of Spanish America may possibly be criticized on the ground of inexpediency or that of irregularity in following the rules governing such cases; but the author has been led to do so by the apparent natural tendency of English-speaking people to sadly mispronounce such names, even when spelled precisely the same in Spanish and English; for example: Bogotá (Bo-go-tah′), Davíd (Dah-veed′), Ecuadór (Ek-wah-dōr′), Salvadór (Sal-vah-dōr′), Generál (Hen-er- ahl′), and Trinidád (Tre-ne-dad′), which in English (at least com- monly) are pronounced Bo-gó-tah, Da′-vid, Ek′-wa-dor, Sal′-va-dor, Gén-er-al and Trín-i-dad, respectively. There are, of course, definite rules of accentuation in the Spanish language, but these are unknown to most Americans and other English-speaking people, and therefore the accent is frequently given where the rules do not require it. In a majority of cases, where the accent mark does not appear the accent is normal, that is, the emphasis falls on the penultimate syllable.[3] Other cases where the accent is omitted are those words in which the Spanish accent agrees with the prevalent English one; as Nicaragua, Venzeuela, Yucatan, etc. In one case (that of Santa F6) general usage is followed, although the accent mark is, of course, wholly superfluous in a word of only one syllable.
