Tiny Camera Shows Bird’s Amazing Feeding Habits
This is the first time researchers have been able to watch first-hand the amazing feeding techniques of these fascinating birds, which occur off the coast of Argentina.
The footage shows the cormorant briefly on the surface before diving for the bottom. The camera is attached to the bird’s back, so the view is of its head as it pumps its feet to swim deeper. When it finally reaches the ocean floor, it explores a vast area searching for food. It eventually finds an elongated fish, which it brings to the surface to eat.
The footage came from Punta León in Patagonia, Argentina, a coastal protected area supporting more than 3.500 pairs of imperial cormorants. A WCS scientific team, led by Flavio Quintana, has been studying the cormorants’ feeding behavior for the past ten years. The team was joined by Carlos Zavalaga along with Ken Yoda from the Univ. of Nogoya, Japan to fit the camera on the bird.
The WCS team has tracked more than 400 cormorants along the Patagonian Coast of Argentina using cutting edge technological tools such as multi-channel archival tags and high resolution GPS-loggers. This information will help identify priority feeding areas to help design new protected areas and to understand environmental conditions that affect cormorant populations.
WCS, with the support of the Liz Claiborne and Art Ortenberg Foundation, Mitsubishi Corporation Foundation for the Americas and other generous donors, has worked in Patagonia for more than five decades and has helped establish a series of protected areas to safeguard local wildlife, including penguins, albatross and elephant seals.
