Field updates: Argentina, September 2023

Boersma Lab, Updates from the Field /

Written by Dr. Dee Boersma The ongoing pinniped (seals and walruses) die-off on Peninsula Valdés is catastrophic. Our contacts in Argentina–two local veterinarians (Marci Uhart and Ralph Vanstreels), and Claudia Campagna of WCS–tell us that hundreds and potentially thousands of sea lions and elephant seals have died. Avian flu (more widely known as bird flu) has devastated seabird populations throughout

Authors: Eric L. Wagner, Esteban Frere, P. Dee BoersmaJournal: Marine Pollution BulletinDOI: 10.1016/j.marpolbul.2023.11 Photo credit: National Ocean Service Image Gallery Summary Summary written by Sofia Denkovski Argentinian oil and effects on seabirds Surveys from 1982-1990 suggested more than 40,000 penguins died per year in Chubut and Santa Cruz from chronic oiling. This was hypothesized to be due to the colonies’

Should I stay or should I go: factors influencing mate retention and divorce in a colonial seabird

Authors: Eric L. Wagner, Caroline D. Cappello, P. Dee BoersmaJournal: Animal BehaviourDOI: 10.1016/j.anbehav.2022.08.002 Divorce among serially monogamous birds can lead to increased reproductive success if an individual obtains a higher-quality mate or nest site, or it can lead to lower reproductive success due to lack of pair experience or reduced breeding opportunities…

Site fidelity increases reproductive success by increasing foraging efficiency in a marine predator

Publications /

Authors: Ginger A Rebstock, Briana Abrams, P. Dee BoersmaJournal: Behavioral EcologyDOI: 10.1093/beheco/arac052 Seabirds must find food efficiently in the dynamic ocean environment to succeed at raising chicks. In theory, site familiarity, gained by prior experience in a place, should increase foraging efficiency when prey is predictable, and translate into increased reproductive success, though this is difficult to test empirically…

Unprecedented heat mortality of Magellanic Penguins

Publications /

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.
