Welcome to the next installment of Meet CES, where we get to meet the people behind the Center for Ecosystem Sentinels. Next up is Dr. Katie Holt, who just earned her PhD at the University of Washington! Katie’s been with the Boersma Lab since October 2015, when she was hired to replace Caroline Cappello as Lab Coordinator. She started graduate […]
Written by Katie Holt I kicked off the year by heading the joint meeting of the Pacific Seabird Group and the Waterbird Society in San José, Costa Rica! At the conference, I presented my research on how commercial fishing reduces the rate at which adult seabirds acquire food while foraging. As the only member of the Boersma Lab in attendance,
Thanks to the generous support of Zoo Augsburg in Germany, Dr. Eric Wagner and Katie Holt were able to return to Punta Tombo for a couple of weeks in April. There, they put twenty satellite tags on penguins—ten females and ten males—that were about to start their post-breeding migration. As of today 18 satellite tags are still transmitting to our
Since 2015, we have deployed automatic weighbridges to track the foraging success of Magellanic penguins at one of their largest breeding colonies – Punta Tombo, Argentina. These weighbridges weigh penguins noninvasively as they leave the nesting area to forage and when they return to feed their chicks. This helps us track whether these penguins are finding enough food for themselves

In January and February of 2023 Dr. Dee Boersma, along with PhD students Katie Holt (Boersma Lab) and Erik Johansson (Abrahms Lab), spent six weeks in Punta Tombo to set up the remote scales that weigh penguins on their way in and out of the breeding area, and followed 19 penguins using GPS tags. The three of them were also able
Authors: Katie Holt and Dee BoersmaJournal: Ornithological ApplicationsDOI: https://doi.org/10.1093/ornithapp/duab052 Abstract excerpt: Extreme weather events are becoming more frequent and severe, leading to an increase in direct, adverse thermoregulatory impacts on wildlife. Here, we document an unprecedented, single-day, heat-related mortality event of Magellanic Penguins (Spheniscus magellanicus) at Punta Tombo, Chubut Province, Argentina, one of the largest breeding colonies for this species.
