SUMMARY:How do chickadees communicate about the presence and absence of food?
DESCRIPTION:AOS Student Research Grant Seminar\nPresenter: Clay Jones\, Ph.D. student\, University of California Davis; AOS 2023 Josselyn Van Tyne Memorial Research Grant winner \n  \n \nForaging as part of a group can afford social animals benefits such as increased protection from predators and opportunities for social learning\, but not much is known about how animals communicate about variation in food availability or maintain group cohesion while foraging. Carolina Chickadees (Poecile carolinensis) form winter foraging flocks and produce complex\, compositional calls at food sources\, potentially to recruit group members and strengthen social bonds. In a field experiment\, I analyzed differences in Carolina Chickadee vocalizations produced when food was available versus when food access was unexpectedly blocked. This research lends insight into how animals communicate at food sources and share information about changing food conditions\, which could aid their survival in unpredictable environments. \nMore about the Student Research Grant Seminar Series

SUMMARY:Drivers of Rapid Phenotypic and Species Diversification
DESCRIPTION:AOS Research Grant Seminar\nPresenter: Jenna McCullough\, NSF Postdoctoral Fellow\, Natural History Museum of Los Angles County and University of California\, Los Angeles; AOS 2025 Kessel Fellowship winner  \n  \nJenna McCullough\n  \nAs an evolutionary biologist and ornithologist\, I study the tempo and mode of avian evolution—why some bird lineages diversify rapidly while others do not. Natural history museums provide a powerful foundation for addressing these questions by preserving the phenotypic\, genomic\, and ecological record of life through time\, allowing us to connect microevolutionary processes with macroevolutionary patterns. My work spans broad phylogenetic\, geographic\, and phenotypic scales\, linking mechanisms underlying trait evolution—such as color production—to their diversification across species and clades. In this talk\, I will discuss how I use geographic radiations across the Indo-Pacific to revisit historical theories of island evolution and speciation through the lens of modern genomic and phenotypic technologies. \nMore about the Research Grant Seminar Series

SUMMARY:Bird necessities: the importance of small forest islands for behavior in a tropical savanna
DESCRIPTION:AOS Research Grant Seminar\nPresenter: Valentina Gómez-Bahamón\, Assistant Professor\, Virginia Tech; 2023 AOS Latin American and Caribbean Conservation Research Grant \n  \nValentina Gómez-Bahamón\nSavanna birds in the tropics depend on small forest islands for nesting\, roosting\, foraging\, displaying\, escaping predators\, and other essential daily activities. Unfortunately\, these islands are rapidly disappearing as savannas are converted into extensive monocultures of exotic timber species and crops. To understand how birds use these habitats and which ecological characteristics are most important\, we studied bird behavior and habitat attributes across forest islands in the Colombian Orinoquía. I will present the main findings of this research\, highlighting how forest island heterogeneity supports bird communities and the behaviors they depend on. I will also discuss how this work has expanded research for conservation at the Tomogrande Biological Field Station\, contributed to mentoring local early-career researchers\, and fostered outreach activities with local communities to promote the conservation of tropical savanna ecosystems. \nMore about the Research Grant Seminar Series

SUMMARY:Genome-wide DNA methylation varies due to cold temperature acclimation and between tissue types in house sparrows
DESCRIPTION:AOS Research Grant Seminar\nPresenter: Chelsi Marolf\, Visiting Assistant Professor\, Nebraska Wesleyan University; 2025 Werner and Hildegard Hesse Research Grant winner \n  \nChelsi Marolf\nAnimals in temperate regions are facing changing environmental conditions\, including more frequent extreme weather events. Small temperate birds are highly flexible\, increasing their metabolic rates during prolonged exposure to cold winter temperatures. However\, the mechanisms underlying this flexibility remain incompletely understood. In this study\, I assessed whole-genome DNA methylation in house sparrows exposed to warm\, cold\, and fluctuating cold acclimation treatments. Because DNA methylation is an epigenetic marker that can influence gene expression\, I expected methylation patterns to differ between cold-exposed and warm-exposed birds. \nMore about the Research Grant Seminar Series

SUMMARY:Are seabirds at ease? Assessing threats to seabirds in Islote Lobos National Park\, Argentina\, using Magellanic Penguins as sentinel species
DESCRIPTION:AOS Research Grant Seminar\nPresenter: Natalia Rosciano\, Assistant Researcher\, CONICET; 2025 Latin American and Caribbean Conservation Research Grant winner \n  \n \nThe San Matías Gulf\, a biodiversity hotspot in northern Patagonia\, faces growing pressure from hydrocarbon industrial developments. Using Magellanic Penguins as sentinel species\, we combined GPS tracking during the breeding season with particle scattering simulations to assess how oil spills could overlap with critical foraging areas. Penguins foraged mainly northwest of Islote Lobos National Park\, with core areas overlapping up to 76% with simulated spill zones under certain wind conditions. These results provide a baseline for understanding how industrial expansion may threaten penguin foraging grounds and inform conservation planning in one of Argentina’s most productive marine ecosystems.

SUMMARY:Population dynamics\, morphological change and conservation of an endemic island bird in the 21st century
DESCRIPTION:AOS Research Grant Seminar\nPresenter: James Mouton\, Assistant Professor\, The Ohio State University; 2021 AOS Postdoctoral Research Grant winner \n  \n \nThe Island Scrub-Jay (Aphelocoma insularis) is restricted to a single island\, making understanding its response to environmental change particularly important for its long-term conservation. I will explore how morphology and population dynamics have changed in recent years\, including evidence for selection during hotter years and population stability through severe drought\, and discuss what these patterns mean for conservation in the 21st century.

SUMMARY:Lewis's Woodpecker habitat use\, reproduction\, and migratory behavior in post-fire landscapes
DESCRIPTION:AOS Research Grant Seminar\nPresenter: Frank Fogarty\, Associate Professor\, Cal Poly Humboldt; 2023 Kessel Fellowship winner  \n  \n \nLewis’s Woodpecker (Melanerpes lewis) is a declining species of western North America whose unusual behaviors and reliance on recently burned landscapes make it both a conservation priority and a challenging species to study. Dr. Fogarty’s lab has used a range of methods to investigate its habitat use\, home-range size\, nest-site selection\, migratory behavior\, and shifting use of burned and logged forests.  A Kessel Fellowship helped support a master’s project and two undergraduate honors theses to better our understanding recent losses from the species’ breeding range as well as apparent changes in its migratory strategies. Dr. Fogarty will present key findings from this work\, including the first empirical estimates of home-range size and the first confirmed evidence of partial migration in the species. \n  \n

SUMMARY:How are the AOS and the AOS community thinking about AI?
DESCRIPTION:AOS Member Forum\n  \n \n  \nLeaders:  \nMorgan Tingley\, AOS President\nJudith Scarl\, AOS CEO/Executive Director\nAOS Professional Ethics Committee \n  \nDiscussion of recently adopted AI Policy that guides AOS staff\, operations and committees and opportunities for community feedback. At the 2026 AOS annual meeting in Amherst\, Massachusetts\, the AOS Council adopted a policy regarding AI use by staff and committees to guide operations and activities. The objectives of this virtual forum are two-fold: 1) Inform AOS members about the recently adopted policy\, and 2) Listen to the AOS community regarding your ideas on AI. We want to hear from you on what AOS should be thinking about when considering the ethical and appropriate use of AI both in how the society operates and how AOS members use AI in their ornithological work. Are there issues that AOS should be researching? Are there AI-related topics we should be doing outreach on? We want to hear from you! We anticipate this forum will provide key insights to development of a community-wide survey in the next months and at subsequent forums. \n  \nThis forum is free and available to all current AOS members as a membership benefit.  \nThe registration link will send you to the AOS member portal to access the Zoom link to register. Please login to the AOS member portal with your AOS member login credentials. If you are not a current AOS member\, you will be prompted to renew your membership to access this opportunity. \n  \n  \n  \n

SUMMARY:Daily temperature impacts thermogenic flexibility in a high elevation migrant regardless of breeding status
DESCRIPTION:AOS Research Grant Seminar\nPresenter: Jessica Karr\, Postdoctoral Researcher\, University of Massachusetts Amherst; 2024 Josselyn Van Tyne Memorial Research Grant winner \n  \n \nLow temperature and variable precipitation can negatively impact the survival or reproductive success of animals if they generate energetic tradeoffs. However\, despite extensive research\, very few studies have compared thermogenic tradeoffs in the context of variable weather and breeding status – especially in areas where challenging conditions can occur during the early breeding season. Using a migrant songbird that breeds in the eastern Sierra Mountains\, the mountain white-crowned sparrow (Zonotrichia leucophrys oriantha)\, I tested two hypotheses to determine how thermogenic capacity responded to changes in ambient temperature (Low Temperature Hypothesis) and whether thermogenic capacity influenced the onset of reproduction (Reproductive Tradeoff Hypothesis). \n  \n  \n  \n

SUMMARY:Does ecological specificity predict patterns of genetic diversity\, differentiation\, and divergence in a Central American assemblage?
DESCRIPTION:AOS Research Grant Seminar\nPresenter: Jack Hruska\, Postdoctoral Research Associate\, University of Nebraska-Lincoln; 2020 AOS Alexander Wetmore Memorial Research Grant winner \n  \n \nEcological interactions have been shown to be predictive of genetic diversity and divergence. Until recently\, these traits were largely ignored by the field of comparative phylogeography\, which seeks to explain the biotic and abiotic factors that determine population persistence across landscapes. Employing a comparative phylogeographic approach\, we test the predictions of the specialist-generalist variation hypothesis (SGVH) and ask if habitat specificity is predictive of genetic diversity\, differentiation\, and divergence\, in an assemblage of co-distributed birds of northern Central America. While we do not find strong support for the predictions of the SGVH\, we find diversity and differentiation patterns to suggest that ecological specificity is somewhat predictive of genetic outcomes across this assemblage. \n  \n  \n  \n  \n  \n

SUMMARY:Testing abiotic and biotic drivers of fitness and range limits along an elevational gradient in a Himalayan bird
DESCRIPTION:AOS Research Grant Seminar\nPresenter: Pranav Gokhale\, Ph.D. student\, Georgia Institute of Technology; 2025 AOS Alexander Wetmore Memorial Research Grant winner \n  \n \nIn this talk\, I will examine how abiotic and biotic factors shape reproductive success and elevational range limits in Hume’s Warbler across a steep elevational gradient in the western Himalaya. Through intensive nest monitoring\, camera traps\, insect sampling\, and measurements of temperature and precipitation\, I ask how different mechanisms constrain reproduction at the lower and upper limits of the species’ range. I will also show how selection varies among years but can stabilize over longer timescales\, providing insight into how different ecological pressures at opposite range limits may contribute to the evolution of species’ distributions. \n  \n  \n  \n  \n  \n  \n  \n

SUMMARY:Beyond Presence-Absence: Using passive acoustic surveys to estimate the abundance of Arctic-breeding birds
DESCRIPTION:AOS Research Grant Seminar\nPresenter: Morgan Ziegenhorn\, Senior Data Scientist and Acoustic Ecologist | Manomet Conservation Sciences\, Manomet Conservation Sciences; 2025 Kessel Fellowship winner \n  \nEstimating density\, rather than presence-absence\, remains a major challenge for passive acoustic monitoring. However\, density estimates are required to produce population size estimates\, which are a prerequisite for effective management of avian species. In this seminar\, Dr. Ziegenhorn will present and discuss the challenges\, setbacks\, and\, ultimately\, results of a novel method for density estimation that uses a modified version of traditional distance sampling to generate robust density estimates of Arctic-breeding birds from acoustic surveys and deep learning outputs. Ultimately\, the development of efficient\, automated abundance estimation methods such as this is critical for diversifying the monitoring approaches available for fast-declining bird populations. \n  \n  \n  \n  \n  \n  \n  \n  \n  \n

SUMMARY:Urban traffic noise disrupts auditory discrimination performance in Zebra Finches
DESCRIPTION:AOS Research Grant Seminar\nPresenter: Nicole St. Jacques\, Ph.D. candidate\, City University of New York; AOS 2025 Student Research Grant winner \n  \nAnthropogenic urban and traffic noise has been shown to disrupt vocal learning and impact associated neural substrates in juvenile songbirds. However\, less is known about how traffic noise influences auditory song perception and physiological processes in adults. In this talk\, I will share current results from an ongoing operant discrimination task using adult male and female Zebra Finches\, suggesting that New York City traffic noise disrupts song discrimination abilities. Results from a fecal corticosterone analysis revealed that traffic-exposed birds did not have more corticosterone than controls\, suggesting traffic noise may not increase stress\, but disrupt sensory processing\, attention\, and motivation. \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n

SUMMARY:Investigating the role of vocal performance in territorial defense in Bachman's Sparrows (Peucaea aestivalis)
DESCRIPTION:AOS Research Grant Seminar\nPresenter: Lauren Dawson-Scully\, Ph.D. student\, Florida Atlantic University; 2025 AOS Margaret Morse Nice Research Grant winner \n  \nVocal performance functions as a meaningful index signal in many songbird species\, but its role in territorial interactions remains unclear in Bachman’s Sparrows. This study uses a field playback experiment to test how Bachman’s Sparrow males respond\, both behaviorally and vocally\, to rivals varying in vocal performance. Since Bachman’s sparrows have a very large and complex song repertoire\, these results offer valuable insight for how vocal performance operates during competitive interactions in more elaborate vocal systems. \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n

SUMMARY:You are what you eat: diet quality\, display behavior\, and mating success in Greater Sage-Grouse
DESCRIPTION:AOS Research Grant Seminar\nPresenter: Eric Tymstra; Ph.D. candidate in the Graduate Group in Ecology at the University of California\, Davis; 2020 Werner and Hildegard Hesse Research Grant winner \n  \nGreater Sage-Grouse males gather on leks each spring to perform energetically costly courtship displays\, and only a few of them get most of the matings. But what determines which males succeed? In this talk\, I bring together three parts of my dissertation. First\, using more than a decade of data from leks in Wyoming and California\, I show how lek size changes the path to mating success: showing up matters everywhere\, but on larger leks a male’s position relative to copulation hotspots matters more. Second\, using GPS-tagged males\, I ask how foraging choices and sagebrush chemistry relate to display performance\, and find that where a male forages matters more than which plants he browses once he’s there. Third\, I evaluate a fecal biomarker of detoxification as a window into the physiological cost of eating toxic sagebrush\, and what it can and can’t yet tell us about male performance. Together\, these results show how social context\, space\, and diet interact to shape mating success\, with implications for managing sagebrush habitat for sage-grouse conservation. \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n
