. 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.
． 蛇是鸟类巢穴的常见捕食者，因此可能对鸟类种群动态产生重要影响。然而，虽然已知许多物种会吃雏鸟和雏鸟，但很少有物种会吃鸟蛋。为了有效地量化蛇捕食鸟蛋对鸟类种群的影响，关键的第一步是确定哪种蛇会吃掉鸟蛋。不幸的是，关于大多数蛇的饮食习惯的详细信息很少，而且喂养记录的编目也很差，这使得很难确定哪些物种吃鸟蛋，哪些不吃鸟蛋。我们回顾了文献和在线社区科学报告，编制了一份全球确认的以鸟蛋为食的蛇捕食者名单。我们从238个独立的数据来源中收集了123个蛇类群的471条摄食记录，这些记录消耗了至少210种鸟类的卵。记录的地理位置不成比例地代表了采样良好的地区，我们推断许多未包括在我们名单上的蛇也吃鸟蛋。然而，我们发现食卵蛇往往很长(平均最大长度= 2057 mm)，并且主要吃直径较小的卵(平均卵直径= 24 mm)，这表明相对猎物体积是这些相互作用的重要约束。因此，我们预计其他以鸟类为食的蛇可能主要包括与我们的综述中反映的同类和生态相似的物种。通过了解哪些蛇吃鸟蛋，未来的研究可以在研究蛇捕食鸟蛋的生态影响时考虑物种和地点特定的假设。这些结果也可以告诉保护从业者鸟巢成功变化的原因和后果，这可能有助于在设计保护管理计划时做出决策。De la presa es una restricción importante De estas interacciones。穷，穷，穷，穷，穷，穷，穷，穷，穷，穷，穷，穷，穷，穷，穷，穷，穷，穷，穷，穷，穷，穷，穷，穷，穷，穷，穷，穷，穷，穷，穷。conciendo cuales特别消费的huevos de aves，工作室的未来应该考虑hipótesis的特殊情况，特别调查的损失效应ecológicos de la depredación de huevos de aves穷人的serpientes。Esos的结果是，在过去的几个月里，在过去的几个月里，在过去的几个月里，在过去的几个月里，在过去的几个月里，在过去的几个月里，在过去的几个月里，在过去的几个月里，在过去的几个月里，在过去的几个月里，在过去的几个月里，在过去的几个月里，在过去的几个月里，在过去的几个月里，在过去的几个月里，在过去的几个月里，在过去的几个月里，在过去的几个月里，人们一直在做决定。

. 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

. 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. RESUMEN
． 我们使用了红宝石冠小雀(Corthylio calendula)歌曲的存档录音来研究该物种繁殖范围内的歌曲特征、曲目大小和区域方言，并评估方言可能的文化进化。通过对313个个体的录音，我们证实了个体具有单一的歌曲类型，并且存在明显的区域歌曲方言。我们研究了这一物种的三部分歌曲的最后一部分，发现了43种不同的短语类型。我们根据地理特征、生态区域和特定短语类型的明显聚类划分了7个区域。第八个区域对应于已公布的亚种C. C. grinnellii的分布范围，阿拉斯加南部沿海和不列颠哥伦比亚海岸。在每个区域中，两到三种短语类型占主导地位，并且完全或主要在一个区域内发现。我们对地方方言的发现证实，至少就这个短语而言，红宝石冠小王的歌声是习得的，而不是天生的。在迁徙过程中或在非繁殖地鸣叫的物种中，比如这只小kinglet，绘制出的方言地图可以帮助揭示迁徙策略和迁徙连通性。监测方言随时间的变化可以确认文化演变，并阐明歌曲学习的时间和地点。RESUMEN
