New HampshireAudubon Seacoast Chapter Wednesday April14, 2021 7:30 pm Eastern Time (US and Canada) Zoom Program: Ravens, Wolves andPeople Common ravens are known to scavenge fromwolves and people, but the degree to which they exploit these and other sources of food has not beenstudied in detail. In 2019, Matthias Loretto and presenter John Marzluff begantagging ravens in Yellowstone National Park with long-lasting GSM transmitters.After tagging >60 ravens and relating their movements to those of people andwolves, they are gaining an appreciation of the raven's reliance on bothproviders. John will describe the movements of territorial and non-breedingravens and relate these to wolf- and human-provisioned foods. He will focus onthe exploits of individual birds to emphasize variability. They observed ravensusing wolf kills, but the ravens' discovery appears more incidental than aresult of following or purposeful search. As they begin to quantify therelationship between wolves and ravens, they may learn more about raven andwolf synchrony, but at present, it appears to be weak, with discovery of killsoccurring during the day rather than after communal roosting. Ravens madeextensive use of anthropogenic resources, including direct handouts, wastewatertreatment ponds, dumps, agriculture, roadkills, and hunter offal. Territorialravens have extensive knowledge of the Greater Yellowstone Ecosystem andexploit areas in excess of 6500 square miles to obtain their yearly needs. Bio: John Marzluff is James W. RidgewayProfessor of Wildlife Science at the University of Washington. His graduate(Northern Arizona University) and initial post-doctoral (University of Vermont)research focused on the social behavior and ecology of jays and ravens. Hecontinues this theme investigating the intriguing behavior of crows, ravens, andjays. His current research focuses on the interactions of ravens and wolves inYellowstone. He teaches Ornithology, Governance and Conservation of RareSpecies, Field Research in Yellowstone, and Natural and Cultural History ofCosta Rica.Professor Marzluffhas written five books and edited several others. His Welcome to Subirdia (2014Yale) discovers that moderately settled lands host a splendid array ofbiological diversity and suggests ways in which people can steward these richesto benefit birds and themselves. His most recent book, In Search of Meadowlarks(2020 Yale) connects our agriculture and diets to the conservation of birds andother wildlife. Dr. Marzluff has mentored over 40 graduatestudents and authored over 140 scientific papers on various aspects of birdbehavior and wildlife management. He is a member of the US Fish and WildlifeService's Recovery Team for the critically endangered Mariana Crow, a formermember of the Washington Biodiversity Council, a Fellow of the American Ornithologist'sUnion, and a National Geographic Explorer.
