No species in this group has been recorded from North America north of Mexico. Since these New World families were monographed by the late eminent ornithologist Dr. C. E. Hellmayr less than 30 years ago, a comparison of the two works is pertinent. Important changes include the elimination of subfamilies, a decrease in the number of species (527 vs. 540), and a great increase in the number of recognized forms (1581 vs. 1163). Several genera have been removed from the Formicariidae, Melanopareia being placed in the Rhinocryptidae, while Psilorhampkz~s, in addition to Ranzphocaenus anti Microbates, are referred to the Sylviidae. Of the genera we note that “Dendroplex ” is merged with Xiphorhynchus, “Dendrophylax” with Leptasthenura, “Drioctistes” with Phacellodomus, “Microxenops” with Xenops, “Apocryplornis” with Grallaricula. Six genera (Oclzetorl~ynclzus, Spartonoica, Hellmayrea, Gyalophylas, Roraimia, and Simoxenojx) are added to the Furnariidae, two (Xenovnis and iMyrmop/cyZax) to the Formicariidae. This reviewer is impressed not only with the standard of accuracy and attention to details characteristic of Peters’ work, but also with his conservative taxonomic treatment in contrast with the works of certain other authors.-James Bond.","PeriodicalId":54404,"journal":{"name":"Wilson Journal Of Ornithology","volume":"135 1","pages":"101 - 102"},"PeriodicalIF":0.3,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48312438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Spectra of feather samples are impacted by the substrate color against which they are measured","authors":"Joanna K. Hubbard, Zachary W. D. Williard","doi":"10.1676/22-00056","DOIUrl":"https://doi.org/10.1676/22-00056","url":null,"abstract":"ABSTRACT Many studies of animal and plumage coloration use spectrometry to obtain objective measurements of colorful traits. Objective measurements of plumage color are particularly important as the avian visual system is distinct from our own and subjective color assessment by researchers can miss important color variation or signals. As spectrometry has become one of the preferred methods of color measurement, appropriate methodologies and reporting standards have refined and improved the technique as well as increased our ability to make comparisons across studies. Here, we investigate another important methodological decision by examining how the background color against which feather samples are measured impacts the reflectance spectra and color descriptors commonly extracted from those spectra. We used feather samples collected from Eastern Bluebirds (Sialia sialis) and Barn Swallows (Hirundo rustica erythrogaster) to determine how black and white backgrounds influence color measurements. We measured the same feather sample in the same arrangement against a white index card and a piece of black cardstock and found that measurements taken against a white background tended to yield higher reflectance curves, which also resulted in significant differences in some color descriptors. Lightly colored, wispy, and small feathers seem to be particularly susceptible to background color effects. Thus, researchers using spectrometry to measure colorful traits should carefully consider the background against which they are taking measurements as white backgrounds tend to increase reflectance and certain feather colors or morphology (light and wispy) may be particularly susceptible to spectral contamination. RESUMEN (Spanish) Muchos estudios sobre coloración animal y del plumaje utilizan la espectrometría para obtener medidas objetivas de rasgos de color. Las medidas objetivas del color del plumaje son particularmente importantes debido a que el sistema visual de las aves es distinto del nuestro y la evaluación subjetiva del color por parte de los investigadores puede omitir algunas variaciones importantes del color o en señales de color. A medida que la espectrometría se ha convertido en uno de los métodos preferidos para medir el color, las metodologías apropiadas y los estándares para reportarlo se han ido refinando y mejorando su técnica, además de incrementar nuestra capacidad para realizar comparaciones entre estudios.

{"title":"Consequences of topography on nest microclimate and reproductive success in an open-cup nesting passerine","authors":"K. Williams, Laura R. Dykstra, Jacob P. Sieg, C. Dykstra","doi":"10.1676/22-00061","DOIUrl":"https://doi.org/10.1676/22-00061","url":null,"abstract":"ABSTRACT Nest microclimate can be influenced by subtle differences in nest location such as topography and aspect, and can differ among nests located relatively close to each other. More favorable microclimates at nests may influence birds' nest-site selection and reproductive outcome. Yet most studies of nest microclimate have considered cavity-nesting species, and few have investigated a passerine open-cup nester. We compared the nest microclimates of 87 Hooded Warbler (Setophaga citrina) nests built in subtly different topographical positions (ridge, slope, and valley) at Tar Hollow State Forest in southern Ohio. We then examined the relationships of nest topographical position and aspect to parental age and to 3 measures of reproductive outcome. We predicted that older, more experienced birds would nest in more favorable (warmer) sites and would have greater reproductive success at these sites. We found significant differences in nest microclimate among nest sites that differed subtly in topography and aspect. As expected, nest sites in valleys had significantly lower ambient temperatures (mean, minimum, and maximum daily temperatures) than those higher up on the ridges. However, nest aspect had few effects on ambient temperature at nest sites. When considering the nest sites used by females of different ages, we found some evidence that older (after second year) females had warmer nest sites than younger (second-year) females, supporting our prediction. However, there was no evidence that older females or warmer nests were associated with greater reproductive success, contrary to our expectations. Our findings suggested that although topography significantly influences nest microclimate, factors other than temperature differences are more important determinants of reproductive success, and that other considerations influence the older birds' selection of warmer nest sites on ridges. The relationships among nest microclimate, nest site selection, and reproductive success are complex and require additional study for open-cup nesters.

Microclimas más favorables pueden influir en la selección de sitio de los nidos que hacen las aves y en su desenlace reproductivo.

The diet of this species has not yet been described in Florida, although this state contains an endemic subspecies (B. l. extimus) first described more than 100 years ago. This study characterizes the prey items Red-shouldered Hawks provided to their nestlings in southern Florida using nest cameras at 2 nests in spring 2018 and 4 nests in spring 2019. Seventy-two percent of 1,024 recorded prey deliveries were identifiable to class. Reptiles and amphibians were the most frequently consumed prey classes, as expected, given that Red-shouldered Hawks were previously found to consume more mammals in their northern range and more amphibians and reptiles in their southern range. The diet breadth was lowest at the most urban nest in this study. Each pair successfully fledged all nestlings present when the cameras were installed, although they provided a wide variety of prey amounts and types. RESUMEN (Spanish) La dieta del gavilán Buteo lineatus ha sido descrita en al menos 12 estados. La dieta de esta especie no ha sido aún descrita en Florida, aunque en el estado se ha registrado una subespecie endémica (Buteo lineatus extimus) descrita por primera vez hace más de 100 años. Este estudio caracteriza las presas que los gavilanes Buteo lineatus usaban para alimentar a sus polluelos en el sudeste de Florida usando cámaras en 2 nidos en la primavera del 2018 y en 4 nidos en la primavera del 2019. Setenta y dos por ciento de las 1024 presas llevadas registradas fueron identificadas a clase. Reptiles y anfibios eran las clases de presas más frecuentemente consumidas, como era esperado, ya que los gavilanes Buteo lineatus consumen más mamíferos en la parte norteña de su distribución y más anfibios y reptiles en la parte sureña. La amplitud de dieta era menor en la mayoría de nidos urbanos en este estudio.
