{"title":"Snake predators of bird eggs: a review and bibliography","authors":"J. Barends, B. Maritz","doi":"10.5751/jfo-00088-930201","DOIUrl":"https://doi.org/10.5751/jfo-00088-930201","url":null,"abstract":". Snakes are frequent predators of bird nests and therefore potentially have an important impact on bird population dynamics. However, while many species are known to consume nestlings and chicks, few species have been recorded consuming bird eggs. To effectively quantify the effects of bird egg predation by snakes on bird demographics, a key first step is to identify which snake species consume bird eggs. Unfortunately, detailed information on the dietary habits of most snakes is scarce and feeding records are poorly cataloged, making it difficult to ascertain which species do and do not eat bird eggs. We reviewed the literature and online community science reports to compile a global list of confirmed snake predators of bird eggs. In total, we gathered 471 feeding records of 123 snake taxa consuming the eggs of at least 210 bird species from 238 individual data sources. Geographical locations of records disproportionately represented well-sampled regions, and we infer that many snake species not included on our list also consume bird eggs. However, we found that oophagous snakes tend to be long (mean maximum length = 2057 mm) and mostly eat eggs that are small in diameter (mean egg diameter = 24 mm), suggesting that relative prey bulk is an important constraint of these interactions. Therefore, we expect that other snakes that eat birds are likely to mostly include congeneric and ecologically similar species to those reflected in our review. By knowing which snakes consume bird eggs, future research can consider species- and site-specific hypotheses when investigating the ecological effects of bird egg predation by snakes. Those results can also inform conservation practitioners on the causes and consequences of variation in nest success that may aid in decision-making when designing conservation management plans. de la presa es una restricción importante de estas interacciones. Por lo tanto, esperamos que otras especies que comen aves, muy probablemente incluyen especies congenéres o ecológicamente similares a las incluidas en nuestra revisión. Conociendo cuales especies consumen huevos de aves, las estudios futuros pueden considerar hipótesis especificas al sitio y a la especie al investigar los efectos ecológicos de la depredación de huevos de aves por serpientes. Esos resultados pueden también informar a conservacionistas sobre las causas y consecuencias de la variación en el éxito de los nidos, lo cual puede ayudar en la toma de decisiones durante el diseño de planes de manejo para conservación.","PeriodicalId":15785,"journal":{"name":"Journal of Field Ornithology","volume":"157 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71041601","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":"Parental care in a sexually monomorphic Picid, the Red-headed Woodpecker","authors":"L. Walter, C. Viverette, L. Bulluck","doi":"10.5751/jfo-00089-930203","DOIUrl":"https://doi.org/10.5751/jfo-00089-930203","url":null,"abstract":". Parental care is energetically costly and is thus shared by parents in many bird species. Little is known about how parental care is shared in pairs of sexually monomorphic species. Red-headed Woodpeckers ( Melanerpes erythrocephalus ) are a sexually monomorphic and socially monogamous species in an almost exclusively dimorphic family (> 99% of species; Picidae). We assessed duration of diurnal incubation and brooding and frequency of nestling provisioning and nest cleaning for individually marked breeding Red-headed Woodpeckers at Fort A.P. Hill, Virginia, USA. Individuals were genetically sexed using DNA from feather samples. In addition to parent sex, we evaluated the influence of nestling characteristics (brood size and nestling age) and exogenous factors (habitat type, date, and maximum daily temperature) on parental care behaviors. We recorded and analyzed video at nests during the incubation and nestling stages. We found that females diurnally incubate more than males and males almost exclusively remove fecal sacs from nests. Using generalized linear mixed models, we found females brood young nestlings more than males, but males are the only parent to enter the cavity when chicks are > 10 days old. We found provisioning peaked during the middle of the nestling period, and provisioning frequency was higher in early summer (before 7 July) compared to late summer. The seasonal reduction in provisioning could be related to resource availability but warrants further study. This division of reproductive roles is common in dimorphic","PeriodicalId":15785,"journal":{"name":"Journal of Field Ornithology","volume":"1 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71041649","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":"Regional song dialects of the Ruby-crowned Kinglet","authors":"E. Pandolfino, L. Douglas","doi":"10.5751/jfo-00120-930206","DOIUrl":"https://doi.org/10.5751/jfo-00120-930206","url":null,"abstract":". We used archived recordings of Ruby-crowned Kinglet ( Corthylio calendula ) songs to examine characteristics of the song, repertoire size, and regional dialects across the species’ breeding range and to assess possible cultural evolution in dialects. Using recordings of 313 individuals, we confirmed that individuals have a single song type and that there are distinct regional song dialects. Our examination of phrases that form the last of this species’ 3-part song revealed 43 different phrase types. We defined seven regions based on geographic features, ecoregions, and obvious clustering of particular phrase types. An eighth region corresponded to the published range of the subspecies C. c. grinnellii , coastal southern Alaska and the British Columbia coast. In each of those regions, two to three phrase types dominated and were found exclusively or primarily within a single region. Our finding of regional dialects confirms that the song of the Ruby-crowned Kinglet is, at least with respect to this phrase, learned rather than innate. In species, such as this kinglet that sing during migration or in their non-breeding range, mapped dialects can help reveal migration strategy and migratory connectivity. Monitoring changes in dialects over time can confirm cultural evolution and shed light on both the timing and location of song learning.
