Research done by scientists at the University of Hawaiʻi\, National Parks Service\, and United States Geological Survey in Hawaiʻi Volcanoes National Park over the course of three years elucidated some of these effects. Results from this study suggest that Hawaiʻi ʻamakihi surviving the acute stage of infection may not suffer negative long-term impacts to their fitness. \nMore about the Student Research Grant Seminar Series URL:https://americanornithology.org/calendar/assessing-the-long-term-impacts-of-chronic-infection-with-avian-malaria-in-hawaii-amakihi/ CATEGORIES:Events LOCATION:https://americanornithology-org.zoom.us/webinar/register/WN_DtD_ou1xQRusmHMAFeuVVg END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/New_York:20260427T120000 DTEND;TZID=America/New_York:20260427T130000 DTSTAMP:20260918T105800 CREATED:20260324T174349Z LAST-MODIFIED:20260324T174733Z UID:10000030-1777291200-1777294800@americanornithology.org SUMMARY:Impact of gut microbiome modulation on nesting house sparrow physiology DESCRIPTION:AOS Student Research Grant Seminar\nPresenter: Kristen Rosamond\, Ph.D. candidate\, University of Missouri-St. Louis; AOS 2023 Josselyn Van Tyne Memorial Research Grant winner \n  \n \nThe gut microbiome undergoes succession in early life and plays a key role in shaping host immunity\, and perturbations during this time period can have lasting consequences for physiological function. Here\, I aimed to experimentally disrupt the gut microbiome of wild house sparrow nestlings using probiotics or antibiotics\, followed by an immune challenge to explore whether such manipulations impact host physiology. I will present preliminary results placing these dynamics in an ecological context\, where the effects of such perturbations in wild animals remain poorly understood. \nMore about the Student Research Grant Seminar Series URL:https://americanornithology.org/calendar/impact-of-gut-microbiome-modulation-on-nesting-house-sparrow-physiology/ CATEGORIES:Events LOCATION: END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/New_York:20260504T120000 DTEND;TZID=America/New_York:20260504T130000 DTSTAMP:20260918T105800 CREATED:20260212T192803Z LAST-MODIFIED:20260324T175216Z UID:10000025-1777896000-1777899600@americanornithology.org SUMMARY:Geometric morphometrics of the avian skull related to the presence of the postorbital ligament DESCRIPTION:AOS Student Research Grant Seminar\nPresenter: Samantha Gartner\, Assistant Professor\, East Stroudsburg University; AOS 2024 Postdoctoral Research Grant winner\n \n \nPrevious work on cranial ligaments in birds has found the postorbital ligament to affect the cranial kinesis of the bird skull. This talk attempts to integrate skeletal shape with the presence or absence of the postorbital ligament. We find no large scale patterns across the bird phylogeny and instead find smaller scale patterns between sister groups\, indicating the potential plasticity of the evolution of cranial ligaments. \nMore about the Student Research Grant Seminar Series URL:https://americanornithology.org/calendar/geometric-morphometrics-of-the-avian-skull-related-to-the-presence-of-the-postorbital-ligament/ CATEGORIES:Events LOCATION:https://americanornithology-org.zoom.us/webinar/register/WN_XGkChYSCSBaOsaRR6C0mLg END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/New_York:20260511T120000 DTEND;TZID=America/New_York:20260511T130000 DTSTAMP:20260918T105800 CREATED:20260212T201023Z LAST-MODIFIED:20260324T175302Z UID:10000029-1778500800-1778504400@americanornithology.org 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 URL:https://americanornithology.org/calendar/how-do-chickadees-communicate-about-the-presence-and-absence-of-food/ CATEGORIES:Events LOCATION:https://americanornithology-org.zoom.us/webinar/register/WN_lj8tc5kORQyCygvvEo5iPg END:VEVENT BEGIN:VEVENT DTSTART;VALUE=DATE:20260803 DTEND;VALUE=DATE:20260808 DTSTAMP:20260918T105800 CREATED:20260127T144250Z LAST-MODIFIED:20260218T195135Z UID:10000001-1785715200-1786147199@americanornithology.org SUMMARY:AOS 2026 Annual Meeting: Hope Is the Thing with Feathers DESCRIPTION:Join us at the 144th annual meeting of the American Ornithological Society (AOS). \nFollowing our long legacy of vibrant annual meetings\, the 2026 meeting will once again offer a great opportunity for sharing and discussing scientific research in all areas involving birds. \nWe envision a broad discussion of research that spans the breadth of modern ornithology through plenaries\, symposia\, workshops\, roundtable discussions\, contributed papers\, and posters.

AOS 2026 attendees are invited to attend this event. \nIn the face of challenges and uncertainties around funding\, employment\, academic freedoms\, civil liberties\, social values\, conservation efforts\, and more\, building community is more important than ever. Given the success of a similar community-building event last year\, we invite you all to gather once more for a community discussion and support session. \nAOS representatives will share Society responses to U.S. federal policy changes so far. In small groups\, participants will share strategies that have helped them navigate these times as well as brainstorm and provide feedback for how the AOS and other institutions can better support the community. \nEVENT INFORMATION URL:https://americanornithology.org/calendar/aos-2026-community-forum/ LOCATION:University of Massachusetts Amherst\, 1 University Dr\, Amherst\, Massachusetts\, 01003 CATEGORIES:Events END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/New_York:20260914T120000 DTEND;TZID=America/New_York:20260914T130000 DTSTAMP:20260918T105800 CREATED:20260831T162215Z LAST-MODIFIED:20260903T185808Z UID:10000033-1789387200-1789390800@americanornithology.org 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 URL:https://americanornithology.org/calendar/drivers-of-rapid-phenotypic-and-species-diversification-seminar/ CATEGORIES:Events LOCATION:https://americanornithology-org.zoom.us/webinar/register/WN_--2SDBm6QnuW5_m6zFRIow END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/New_York:20260917T150000 DTEND;TZID=America/New_York:20260917T160000 DTSTAMP:20260918T105800 CREATED:20260902T150055Z LAST-MODIFIED:20260902T150507Z UID:10000035-1789657200-1789660800@americanornithology.org SUMMARY:Faculty Careers in Ornithology at Primarily Undergraduate Institutions DESCRIPTION:AOS Professional Development Webinar\n \nPanelists: \nDr. Mike Butler\, Professor and Department Head of Biology\, Lafayette College\nDr. Jenny Uehling\, Assistant Professor of Biology\, West Chester University\nDr. Kristen Covino\, Associate Professor of Biology\, Loyola Marymount University\nDr. Anna Forsman\, Assistant Professor of Biology\, Colby College\nDr. Dan Baldassarre\, Associate Professor\, Provost Teaching Fellow\, and Director of Rice Creek Bird Observatory; SUNY Oswego \nModerator: \nDr. Jenn Houtz\, Assistant Professor of Biology\, Allegheny College \nWhat is it really like to be an ornithologist at a Primarily Undergraduate Institution (PUI)?

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 URL:https://americanornithology.org/calendar/bird-necessities-tropical-savannah-seminar/ CATEGORIES:Events LOCATION:https://americanornithology-org.zoom.us/webinar/register/WN_3CVon3-lSKGiWp48M_J8qA END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/New_York:20260923T150000 DTEND;TZID=America/New_York:20260923T160000 DTSTAMP:20260918T105800 CREATED:20260903T212012Z LAST-MODIFIED:20260903T212045Z UID:10000036-1790175600-1790179200@americanornithology.org SUMMARY:Accessibility in science communication: Reducing barriers to effective knowledge sharing DESCRIPTION:AOS Professional Development Webinar\n  \n \nPresenter: \nMartha Barta\, AOS Elective Student Councilor; Ph.D. Student\, Tulane University \nModerator: \nSara Padula \nCommunicating your research to a broad audience is a critical part of today’s scientific process\, and prioritizing accessibility in science communication helps ensure that your ideas and findings are disseminated widely and openly.

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 URL:https://americanornithology.org/calendar/genome-wide-dna-methylation-varies-due-to-cold-temperature-acclimation-and-between-tissue-types-in-house-sparrows/ CATEGORIES:Events LOCATION:https://americanornithology-org.zoom.us/webinar/register/WN_yppyGmm7SyqSpaHqjMaB1A END:VEVENT END:VCALENDAR
