Abstract We examined Red-tailed Hawk (Buteo jamaicensis) nestling diets in Reno and Sparks, NV, USA during the 2015 2016 breeding seasons. Field researchers nest cameras recorded 1348 prey items spanning 28 species at 88 nests. Prey consisted of 86% mammalia, 10% aves 4% reptilia. Differential selection occurred among population individual nests relative to an expected diet. Diet breadth differed between increased with urban density. Avian consumption mammalian reptilian impervious areas. When were plotted on a continuous density spectrum, suburban areas decreased toward core was inversely correlated avian prey. Mammalian end April mid-May before increasing through remainder season (mid-June). peaked May season, varied little. The geographic patterns consumed our study reflect those cities elsewhere. As area changes, we predict that densest populations Hawks will continue reside where diversity abundance are highest. This one first studies record diet revealed how used food resources.

Global climate change has increased average environmental temperatures world-wide, simultaneously intensifying temperature variability and extremes. Growing numbers of studies have documented phenological, behavioural morphological responses to in wild populations. As systemic signals, hormones can contribute orchestrating many these phenotypic changes. Yet little is known about whether mechanisms like hormonal flexibility (reversible changes hormone concentrations) facilitate or limit the ability individuals, populations species cope with a changing climate. In this perspective, we discuss different by which flexibility, primarily glucocorticoids, could promote versus hinder evolutionary adaptation regimes. We focus on because it key gradient influenced change, easy quantify, its links are well established. argue that reaction norm connect individual population-level species-wide patterns will be critical for making progress field. also develop case study urban heat islands, where several questions regarding addressed. Understanding allow animals when conditions become more challenging help predicting vulnerable ongoing change.

Global contamination of environments with lead (Pb) poses threats to many ecosystems and populations. While exposure Pb is toxic at high concentrations, recent literature has shown that lower concentrations can also cause sublethal, deleterious effects. However, there remains relatively little causal investigation how environmental affects ecologically important behaviors. Behaviors often represent first-line responses an organism its internal physiological, molecular, genetic a changing environment. Hence, better understanding behaviors are influenced by pollutants such as generates crucial information on species coping the effects pollution more broadly. To understand sublethal behavior, we chronically exposed adult wild-caught, captive house sparrows (Passer domesticus) Pb-exposed drinking water quantified suite behavioral outcomes: takeoff flight performance, activity in novel environment, in-hand struggling breathing rate while being handled experimenter. Compared controls (un-exposed water), environmentally relevant exhibited decreases performance reduced movements environment following 9-10 weeks exposure. We interpret this results be consistent influencing fundamental neuro-muscular abilities, making it difficult for birds mount faster activities. It likely suppression would increase predation risk similar wild; hence, conclude observed could influence fitness outcomes individuals populations altering ecological interactions within naturalistic settings.

Urbanization represents a dramatic and relatively rapid change in the environment that has profound impacts on wild animals. Shifts behavior endocrine mechanisms of stress response could allow animals to successfully survive reproduce urban habitats. Numerous studies have examined behavioral physiological responses territory-holding male songbirds urbanization. However, breeding females likely experience anthropogenic noise, light at night, human disturbance more frequently, their coping these disturbances are limited during incubation. Moreover, face higher energetic demands (allostatic load). Understanding how some species cope with novel habitats requires studying individuals facing greatest challenges, such as females. Therefore, we compared glucocorticoid recovery from between rural female song sparrows (Melospiza melodia) If facultative adjustments birds habitats, predicted would return parental care behaviors after standardized stressor soon or sooner than females, lower stressor. We captured end incubation period measured (corticosterone) levels baseline 30 min restraint. Concurrently, installed radio frequency identification (RFID) systems nest capture time behaviors. found incubating had significantly corticosterone when controlling for sampling timepoint (baseline restraint-induced) rural. Nest times did not differ across latency was correlated levels. Our findings consistent prior work our study sites; males provide restraint-induced The absence relationship glucocorticoids makes it unlikely hormones directly regulate care, but reflect resistance, which been hypothesized permit breed challenging conditions
