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. RESUMEN (Spanish) El microclima de los nidos puede ser influenciado por diferencias sutiles en la localización del nido como la topografía y el aspecto y puede diferir entre nidos localizados relativamente cerca uno del otro. Microclimas más favorables pueden influir en la selección de sitio de los nidos que hacen las aves y en su desenlace reproductivo. Sin embargo, muchos estudios de microclima de nido han considerado especies que anidan en cavidades y pocos han investigado especies paserinas de anidación de copa abierta. Comparamos microclimas de 87 nidos de la reinita Setophaga citrina contruidos en posiciones topográficas ligeramente distintas (cresta, ladera y valle) en Tar Hollow State Forest, al sudeste de Ohio. Examinamos luego la relación de la posición topográfica del nido con la edad parental y 3 medidas del resultado reproductivo. Nuestra predicción fue que las aves más viejas anidarían en sitios más

ABSTRACT The diet of the Red-shouldered Hawk (Buteo lineatus) has been described in at least 12 states. 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. Cada pareja tuvo éxito en emancipar a los polluelos que fueron grabados, aunque les dieron presas que variaron ampliamente en tipo y cantidad.

红肩鹰(Buteo lineatus)的饮食至少在12个州被描述过。该物种的饮食尚未在佛罗里达州被描述，尽管该州包含一种地方性亚种(B. l. extimus)在100多年前首次被描述。本研究在2018年春季的2个巢穴和2019年春季的4个巢穴中使用巢穴摄像机，描述了红肩鹰在佛罗里达州南部为其巢穴提供的猎物。在1,024次记录的猎物交付中，72%是可识别的。正如预期的那样，爬行动物和两栖动物是最常被捕食的猎物，因为之前发现红肩鹰在其北部活动范围内捕食更多的哺乳动物，在其南部活动范围内捕食更多的两栖动物和爬行动物。在本研究中，大多数城市巢的饮食宽度最低。当摄像机被安装时，每一对都成功地孵出了所有的雏鸟，尽管它们提供了各种各样的猎物数量和类型。resume(西班牙语)La dieta del gavilán Buteo lineatus ha sido desita en al menos 12 estados。在佛罗里达州，有一个特别登记的地方，特别登记的地方，特别登记的地方，特别登记的地方，特别登记的地方，特别登记的地方，特别登记的地方，特别登记的地方，特别登记的地方，特别登记的地方，特别登记的地方，特别登记的地方，特别登记的地方，有más de 100 años。Este estustudio设计了一幢位于佛罗里达州的建筑，由Buteo lineatus usaban paralimentar和suspolluelos组成，由usando cámaras设计，2018年和2019年分别为2幢和4幢。在一个类中，将所有的注册表和标识符作为一个类，然后将所有的注册表和标识符作为一个类。爬行动物通过抗菌动物和爬虫类通过抗菌动物más freuentemente consumidas, como era esperado, ya que los gavilanes Buteo lineatus consumen más mamíferos en la partite norteña de su distribución y más抗菌动物en la partite sureña。La振幅de dieta era menmenet en La mayoría de nidos urbanos en este studio。加拿大的自由和自由是一种自由，一种自由，一种自由，一种自由，一种自由，一种自由，一种自由，一种自由，一种自由。Palabras clave:植物的振幅análisis de hábitat cámaras和植物的梯度，没有原生植物
