    Abstract: Rates of karyotypic change in birds are used to estimate that, over the longterm history of a wide assortment of genera, avian effective population sizes have averaged on the order of 100. This result is consistent with the results of electrophoretic studies of geographic variation of allelic frequencies within species but is somewhat less consistent with the results obtained from demographic modeling. Three methodologically independent analyses have now corroborated the hypothesis that avian effective population sizes are typically of the order of 102 or larger.

    Abstract: ABSTRACT ∙ The higher‐level phylogenetic relationships of the nightjars and nighthawks (Caprimulgidae) have been challenging for traditional systematics due to their cryptic plumage and conservative morphology. We explored these relationships by combining two previously published molecular datasets with new data to generate a complete matrix (7,104 bp) of evolutionarily disparate sequence elements from four genes for 36 taxa. We analyzed each of the genes separately for base composition heterogeneity and heterozygosity. We analyzed the concatenated matrix in a likelihood framework using seven different partitioning schemes. As the number of subsets in a given partitioning scheme increased, tree length and likelihood score also increased; however, the branching topology was little affected by increasingly complex partitioning schemes. Our best maximum likelihood tree has increased bootstrap support at 13 of 30 ingroup nodes compared with previous analyses, a result likely due to doubling the length of the sequence data. Coalescent‐based species tree inference produced a tree congruent with all strongly supported nodes in the maximum likelihood tree. This topology agrees with previous molecular studies in identifying three small, early branching Old World genera (Eurostopodus, Lyncornis, and Gactornis) and four more speciose terminal clades, representing the New World nighthawks (genus Chordeiles) and three nightjar radiations centered in South America, Central America and the Old World, respectively. Increased node support across the tree reinforces a historical scenario with origins in the region surrounding the Indian Ocean, followed by diversification in the New World and subsequent recolonization and radiation in the Old World. Future work on this group should incorporate additional members of the genera Lyncornis and Eurostopodus, to determine which is the basal lineage of Caprimulgidae.RESUMEN ∙ Relaciones filogenéticas de más alto nivel de los atajacaminos (Aves: Caprimulgidae) en base a un análisis multigénico Las relaciones filogenéticas de más alto nivel de los atajacaminos y añaperos (Caprimulgidae) son un reto para la sistemática tradicional, debido a que el grupo posee morfología poco variable y plumajes crípticos. Exploramos relaciones filogenéticas en el grupo combinando dos conjuntos de datos moleculares ya publicados con nuevos datos. La matriz completa (7,104 bp) se generó con cuatro genes y 36 taxones, incluyendo marcadores con distintos modelos de evolución. Se examinó cada uno de los genes por separado para determinar heterocigosidad y heterogeneidad de la composición de bases. Se analizó la matriz concatenada en un marco de máxima verosimilitud utilizando siete particiones diferentes. La longitud de los árboles filogenéticos y su verosimilitud aumentaron a la par del número de subconjuntos en una partición particular; sin embargo, la topología del árbol varió poco entre particiones. En comparación con topologías publicadas, nuestro árbol de máxima verosimilitud tuvo mejor soporte para 13 de los 30 nodos internos, resultado que podría deberse al uso del doble de los datos de secuencias. El método de árboles de especies basado en coalescencia produjo una topología congruente con la obtenida por máxima verosimilitud. Esta topología concuerda con previos estudios moleculares, identificando tres pequeños géneros del Viejo Mundo como basales en la filogenia (Eurostopodus, Lyncornis y Gactornis), y cuatro clados terminales con más especies. Estos clados terminales representan los atajacaminos del Nuevo Mundo del género Chordeiles, y otras tres radiaciones de América del Sur, Central y del Viejo Mundo. Nuestros resultados sugieren un escenario histórico con orígenes del grupo en la región circundante al Océano Indico, seguido por la diversificación en las Américas y la posterior recolonización y radiación en el Viejo Mundo. Futuros estudios en este grupo deben incorporar miembros adicionales de los géneros Lyncornis y Eurostopodus, lo que permitirá estudiar cuál es el linaje basal de Caprimulgidae.

    Abstract: We propose a new classification of the grouse that brings their taxonomy into agreement with our molecular phylogenetic studies. Our analyses provide, for the first time, a robust estimate of the evolutionary history of these birds. These analyses are based on aligned sequences of 3,809 basepairs of five complete mitochondrial genes. Our classification does not require novel genera and generally results in the maintenance of accepted generic names. Only two mono‐ typic genera are required. We recognize the grouse as a subfamily, Tetraoninae, within the family Phasianidae. We recognize three tribes; these include a tribe (Bonasini, a new taxon) for the ruffed grouse Bonasa umbellus, a tribe (Tetrastini, a new rank) for hazel hens in the genus Tetrastes, and a tribe (Tetraonini, a new rank) for all the remaining species. We divide this last, derived tribe into five subtribes that correspond to 1) Falcipennina (a new taxon) for the sharp‐winged grouse Falcipennis falcipennis, 2) Canachitina (a new taxon) for the New World spruce grouse in the genus Canachites, 3) Tetraonina (a new rank) for the capercaillies and black grouse in the genera Tetrao and Lyrurus, respectively, 4) Centrocercina (a new taxon) for the New World prairie and forest grouse in the genera Tympanuchus, Centrocercus and Dendragapus, and 5) Lagopodina (a new taxon) for the ptarmigans in the genus Lagopus. All the taxa in our classification, at all ranks, are monophyletic with bootstrap support of 95% or more.

    Abstract: The Northern Spotted Owl (Strix occidentalis caurina) is listed as a threatened species. However, the range description given at the time of listing is inconsistent with the range delineation given by the American Ornithologists' Union checklist of North American birds. Despite the quandary that this inconsistency represents regarding the area of protection afforded the Northern Spotted Owl, the range used in listing is consistent with the actual range suggested by mtDNA haplotypes diagnostic for the subspecies. The range description used in the listing decision of the Northern Spotted Owl and in many conservation plans have been repeated through time without a formal revision or basis for support. Based on current knowledge of Spotted Owl locations we revise the range limits for both Northern and California (S. o. occidentalis) Spotted Owls. Redefinición de los Límites de las Distribuciones de Strix occidentalis caurina y S. o. occidentalis: Implicaciones para Conservación Resumen. La lechuza Strix occidentalis caurina se considera amenazada. Sin embargo, la descripción de su rango de distribución hecha al momento en que fue incluida en la lista de especies amenazadas es inconsistente con la delimitación de su rango hecha por la lista de chequeo de aves de Norte América de la American Ornithologists' Union. A pesar de la incertidumbre que esta inconsistencia representa con respecto al área de protección con que cuenta S. o. caurina, el rango empleado al incluirla en la lista es consistente con el rango real sugerido por haplotipos de ADN mitocondrial diagnósticos para esta subespecie. La descripción del rango de distribución empleada para tomar la decisión de incluir a S. o. caurina en la lista de aves amenazadas y para muchos planes de conservación ha sido repetida a través del tiempo sin una revisión formal fundamentada. Con base en el conocimiento actual, en este estudio revisamos los límites de los rangos de S. o. caurina y de la subespecie de California, S. o. occidentalis.
