Mary’s ResearchGate Profile and ORCID

Mary’s research interests lie at the intersection of animal behavior and ecology, especially where human-induced changes to the environment have altered how organisms interact with their habitat and each other. Her dissertation research addresses how birds and bats around high-elevation lakes in the Sierra Nevada mountains use insects as a food resource during the summer breeding season, and how the introduction of non-native trout to those lakes may have altered the dynamics of that food resource. To do so, she is using both long-term audio recordings and traditional observations to address differences in bird and bat activity at lakes with and without trout. A large part of her work is investigating the utility of acoustic recordings in ecological research and management. Mary’s research was funded in part by an NSF Graduate Research Fellowship.  Prior to joining the Graduate Group in Ecology at UC Davis, Mary received her Bachelor’s degree in Biology and English at St. Mary’s College of Maryland in 2009. She has worked as a seasonal field biologist on a variety of wildlife management and monitoring projects in Yosemite, Sequoia, and Kings Canyon National Parks, and for Point Blue Conservation Science, and continues to work in collaboration with the National Park Service. Mary is also interested in the power of natural history, science writing, and outreach to connect the wider community to science. She is a co-founder and curriculum writer for the UC-Davis chapter of GOALS (Girls’ Outdoor Adventure in Leadership and Science).

Sarah’s website:

Sarah is a PhD Candidate in the Graduate Group in Ecology. Her research interests encompass animal communication, ornithology, breeding biology, and sensory ecology. Sarah is passionate about understanding how organisms use their sensory systems to obtain and transfer information, especially in the context of mate choice and individual recognition. She is particularly interested in the more cryptic and often overlooked chemical senses in birds. Sarah’s dissertation is focused on a small, long-lived, monogamous seabird species called the Leach’s storm-petrel (Oceanodroma leucorhoa). Her research explores how this highly olfactory and very stinky bird uses its incredible sense of smell to obtain information at the breeding colony. She uses a combination of behavioral, analytical, and molecular techniques to discern what kinds of information are advertised in the body odor of this species and how individuals use this information for important reproductive behaviors, such as recognizing both their mate and their underground nest. Prior to coming to UC Davis, Sarah graduated with a Bachelor’s degree in Biology and Environmental Studies from Whitman College in Walla Walla, WA. She spent several years studying seabird bycatch in global fisheries at the University of Washington. She has also worked for USFWS surveying seabirds in the Bering Sea, as a technician in a limnology lab, and as an environmental educator.

Carly E. Hawkins (email)

Carly is broadly interested in the effects of anthropogenic noise disturbance on avian social behavior and sexual selection. For her dissertation research, she is investigating whether noise pollution affects extra-pair mating and sperm competition in white-crowned sparrows.  Before joining the Animal Behavior Graduate Group at UC Davis, Carly recently completed her Master’s degree in Biology at The College of William & Mary, where she investigated social responses to traffic noise in free-living red-backed fairywrens (Malurus melanocephalus) and in captive zebra finches (Taeniopygia guttata). Prior to her graduate work, she graduated from Penn State University with a B.S. in Biology (concentration in Ecology) and a minor in Wildlife & Fisheries Science.

Maria C. Ospina (email)

Maria’s previous research experience at the University of Florida, where she graduated with honors in Biology, has ranged from investigating ant-plant mutualisms, coral reefs, to birds. After graduation in 2015, she spent two years living abroad in Asia, Argentina, and Australia, while expanding her skill set in avian field techniques. Drawing from her experience in avian behavior, communication, and conservation, Maria joined the Graduate Group in Ecology seeking to understand how survival mechanisms (e.g. foraging, anti-predator behavior, interspecific, and intraspecific communication) in birds are impacted by anthropogenic disturbance. In other words, how do avian communities mitigate the effects of disturbance caused by human activities to survive? Maria’s dissertation research addresses how wildfire impacts foraging behavior, courtship and reproductive success in a species of conservation concern, the greater sage-grouse. Maria’s interest in community ecology has connections to her experience as an immigrant from Colombia: community support here in the United States helped ease her integration process. Having also worked as a community organizer and digital influencer for the immigrant community in Florida, one of Maria’s central goals is to be a catalyst for marginalized people to learn about the scientific process and potentially pursue a career in STEM.

Eric joined the Patricelli Lab in Fall, 2016. He is a PhD student in the Graduate Group in Ecology. His research interests include behavior, conservation, and sensory ecology. For his dissertation research, Eric is working with the Greater sage-grouse (Centrocercus urophasianus) in Wyoming and Bishop, California in order to answer questions about how individuals forage off-leks and how this may affect lek social structure. He is also interested in social structure of leks and how the social landscape is affected by personalities of individuals and physical structures. Eric is also working on a project with turkey vultures (Cathartes aura) and researching how multimodal behaviors may allow for greater plasticity in the face of human induced rapid environmental change. Unsurprisingly, Eric is motivated by finding ways to inform conservation efforts with behavioral research. Before coming to UC Davis, Eric worked as a seasonal technician and research assistant in various bird-related labs at UC Berkeley and UC Santa Cruz. He also worked as an education program manager for wildlife related nonprofits. Before that, Eric graduated from UC Berkeley with a BS in Molecular Environmental Biology: Animal Health and Behavior. Aside from research, Eric is passionate about natural history, bird-watching, fly-fishing, fitness, and engaging people in science and conservation. In particular, Eric strives to allow underrepresented groups find paths in and to science. As such, Eric is the co-chair of the Education and Outreach committee for the UC Davis chapter of the Society for Conservation Biology. On weekends it is not uncommon to find Eric chest-high in Putah creek chasing down trout and listening to birds. Or watching Netflix. Really a 50/50 there.

Anna completed her PhD in 2017 in the Patricelli Lab through the Animal Behavior Graduate Group. Anna’s dissertation research examined social influences on male breeding displays in greater sage-grouse, thus the degree to which males adjust their strutting behavior in response to market forces—including the number and quality of competing males, the number and quality of females, and the time in the breeding season. To do so, Anna designed a series of field experiments to measure male response to manipulation of the male social stimulus with playback of recorded male strut vocalizations and to manipulation of the female social stimulus with robotic females. To analyze the data from these experiments, Anna and collaborators developed a novel application of a powerful statistical technique to examine male display behaviors using a hidden Markov models (HMM). Anna’s research was funded in part by an NSF Graduate Research Fellowship. In 2016, Anna was awarded the UC Davis College of Biological Sciences Dean’s Mentorship Award for Undergraduate Research for her excellent mentorship of 42(!) undergraduates during her time in the Patricelli Lab.  Anna also received a Professors for the Future (PFTF) fellowship.

Jennifer completed her PhD in the Patricelli Lab in 2015 through the Animal Behavior Graduate Group. Jennifer is interested in the role of biological and climatic variation in shaping plumage coloration in birds. Specifically she studies Gloger’s Rule—the pattern of organisms being darker in areas of higher humidity—a widely followed but poorly understood pattern. Jennifer’s dissertation addressed why this rule exists by examining patterns of geographic variation at multiple levels from the individual to multi-family phylogenies. She examined these questions using specimens from museums across the country. Jennifer’s previous research has addressed diverse topics on captive and wild populations of animals, including the impacts of human disturbance on bluebirds, fluctuating asymmetry in salamanders, plumage variation in terns, and behavioral endocrinology of dark-eyed juncos.  Jennifer’s research was funded in part by a fellowship from the ARCS Foundation (2013-2014).  After graduation from UC Davis, Jennifer for the Environmental Protection Agency. In 2019, she began a position as Director of the Western Great Lakes Bird and Bat Observatory.
