Abstract
ABSTRACT Blue Jays (Cyanocitta cristata) are known to have large vocal repertoires, although no peer-reviewed study had thoroughly overviewed what vocalizations comprise such repertoires. Using 7,153 vocalizations, most of them recorded in central Kentucky, I document 36 Blue Jay vocalization types, provide spectrographs of 31 of them, and present their relative frequency of use. I suggest a hierarchical nomenclature that can be used to classify Blue Jay vocalizations and that can also be used to classify the vocalizations of other corvids. My depiction of the vocalizations of Blue Jays, and suggestion for a generalizable approach to nomenclature establishment, could help advance our knowledge of the functions of Blue Jay vocalizations and of the evolutionary history of them, especially in relation to the New World jay group. RESUMEN (Spanish) la chara Cyanocitta cristata son conocidas por tener amplios repertorios vocales, si bien no hay un estudio arbitrado que haga una reseña exhaustiva de qué vocalizaciones componen dichos repertorios. Usando 7,153 vocalizaciones, la mayoría grabadas en Kentucky central, documento 36 tipos de vocalizaciones de esta chara, presento espectrogramas de 31 de éstas y presento su frecuencia relativa de uso.

Aims & Scope
For more than a century, the Wilson Ornithological Society has published a scholarly journal with form and content readily accessible to both professional and amateur ornithologists. The Wilson Journal of Ornithology is a quarterly publication consisting of major articles based on original studies of birds and short communications that describe observations of particular interest. Each issue also includes reviews of new books on birds and related subjects, as well as ornithological news. Through an endowment from the late George Miksch Sutton, each issue of the Journal includes a full color frontispiece. Each current volume consists of approximately 500 pages. The principal focus of the Journal is the study of living birds, their behavior, ecology, adaptive physiology and conservation.
Although most articles originate from work conducted in the western hemisphere (a large portion of the research on Neotropical birds is published here), the geographic coverage of the journal is global. The Journal is internationally recognized as an important, major journal of ornithology. The Edwards Prize is given annually for the best major article published during the previous year.
The Wilson Journal of Ornithology was formerly named the Wilson Bulletin.
