1. The Protector

    This is a short documentary film that I made for my final year of University. It deals with the issues that some farmers face in the east of France regarding lynx predation on their livestock. The film centers around the work that a handful of people do with guard dogs and how they aid farmers by supplying them with the means to protect their flock.

    • Cattle Increase Predation of Birds at Malheur National Wildlife Refuge

      Steve Herman earned his PhD in zoology from the University of California at Davis and joined the faculty of The Evergreen State College in 1971 where he taught courses in ecology, natural history, and animal behavior. Over the years, he has closely followed the management of livestock grazing at Malheur National Wildlife Refuge, Hart Mountain National Antelope Refuge (both in Oregon), and Sheldon National Wildlife Refuge in Nevada. In this 2004 interview, Herman explains how cattle grazing at Oregon's Malheur National Wildlife Refuge increases the vulnerability of nesting birds to predation, and he comments on one approach of refuge managers to address this problem. This video is an excerpt from a much longer interview with Herman, the full transcript of which appears in the book WESTERN TURF WARS: THE POLITICS OF PUBLIC LANDS RANCHING.

      • White sharks scavenging on whales

        This video is a visual abstract for the scientific publication: Fallows C, Gallagher AJ, Hammerschlag N. (2013). White sharks (Carcharodon carcharias) scavenging on whales and its potential role in further shaping the ecology of an apex predator. PLOS ONE. The full article can be seen here: http://dx.plos.org/10.1371/journal.pone.0060797 ------------------------- Edited by: Christine Shepard - http://christineshepard.com/ Contributing Cinematographer: Matthew Hawksworth, 504 Producers Contributing Photographer: Chris Fallows - http://www.apexpredators.com/ Contributing Cinematographer and Photographer: Neil Hammerschlag - http://www.rsmas.miami.edu/people/faculty-index/?p=neil-hammerschlag Contributing Photographer: Austin Gallagher - http://austingallagher.com/ Music by: Jonsi, "We Bought a Zoo" - http://jonsi.com/ ------------------------- ABSTRACT: Scavenging, a result of a temporary pulse of resources, occurs in virtually all ecosystems containing carnivores, and is an important energy transfer pathway that can impact ecosystem structure and function, and this ecological significance has largely been considered from a terrestrial standpoint; however, little is known about the role of scavenging in shaping the behavioral ecology of marine species, specifically apex predators. Here we present findings from multiple opportunistic observations of white sharks scavenging on whale carcasses in False Bay, South Africa. Observations of white sharks scavenging over successive days provided evidence of strategic and selective scavenging by this species. Moreover, extended daily observations permitted recordings of unique social, aggregative, and feeding behaviors. We further compare these data against observations of natural predation by sharks on seals in the study area. We discuss these data in relation to environmental conditions, shark social interactions, migration patterns, whale biology, and behaviorally-mediated trophic cascades. While the appearance of a whale carcass is largely a stochastic event, we propose that white shark scavenging on whales may represent an underestimated, yet significant component to the overall foraging ecology of this species, especially as individuals attain sexually maturity. ------------------------- The RJ Dunlap Marine Conservation Program (RJD) is a joint initiative of the University of Miami’s Rosenstiel School of Marine & Atmospheric Science and Abess Center for Ecosystem Science and Policy.

        • Coopers Hawk Northern Flicker

          00:39

          from Sitka Groove Added

          Came across this scene on a side street in Cadboro Bay Victoria BC. The hawk (banded as you can see) was fairly oblivious to me shooting from the window of my vehicle. It took off fairly effortlessly with meal in tow when the homeowner came out to see what the heck I was doing with a camera pointed towards his home. The homeowner as it turns out regularly sees Cooper's hawks in this area. PS - What ever you do, do not look at the Flickers blinking eyes... It was hard to watch but certainly would not want to watch a hawks eyes as it starves to death either...

          • White tailed deer (Odocoileus virginianus) predating Critically Endangered New Zealand dotterel eggs (Charadrius o. obscurus)

            00:20

            from James Reardon Added 979 12 4

            This is a piece of cameratrap footage collected on Table Hill in the south of Rakiura/Stewart Island of the introduced white tailed deer (Odocoileus virginianus) predating a southern NZ dotterel nest (Charadrius o. obscurus). The southern sub-species of the NZ dotterel is critically endangered with extinction, numbering less than 300 birds. An extensive cat and rat control programme exists to protect their nesting grounds and the population recovered well from ~60 birds in the early 90s to over 260 by the mid-2000s. However the population appears to have plateaued. Could invasive species such as the white tailed deer be playing a role in this? Hopefully our research will reveal the facts.

                This was the first time we had ever seen shrimp with such a large piece of unconsumed starfish and it was fascinating to watch them working together to move the much larger animal that was capable of moving (granted, slowly) on its own.
