Última Filling the groove: energy flow to seabirds in the Beagle Channel, Tierra del Fuego, Argentina Ecología austral Raya Rey,Andrea; Schiavinin,Adrián. We assessed the energy requirements and the food consumption of the seabird community of the Beagle Channel in summer. We evaluated differences in energy flow among a priori established zones in the study area and among species. We converted data on densities of seabirds in the channel (February and March 1997) into energy demands. Energy flow to seabirds in shallow waters was twice that of in deep waters. Average energy flow in the whole study area was 9.46×10(4) kJ.km-2.day-1. Energy intake rates ranged 4-13×10(4) kJ.km-2.day-1, being higher in zones that include breeding sites or close to them. Imperial Cormorant was the major contributor to energy flow in all the zones followed by the Black-browed Albatross. Kelp Gull was the major contributor in areas...
