Comparison of diving behavior and foraging habitat use between chinstrap and gentoo penguins breeding in the South Shetland Islands, Antarctica (2010, background): “The diving bottom duration is highly correlated with the number of feeding events in penguins ( Simeone and Wilson 2003; Takahashi et al. 2004; Bost et al. 2007).”
Seabird foraging behaviour indicates prey type (2008, methodology): “Other researchers have used other classifications of dive shape, including left or right-skewed dives, or the number of wiggles or steps per dive (Schreer et al. 2001, Simeone & Wilson 2003).”
HOW DO MAGELLANIC PENGUINS COPE WITH VARIABILITY IN THEIR ACCESS TO PREY (2005, background): “…times goes a long way to solving this problem, first because most prey ingested by Magellanic Penguins are taken during extended bottom phases (see Simeone and Wilson 2003) and second because, even in the absence of prey ingestion, these bottom phases are extended by bird choice rather than being…”
Identification of imperial cormorant Phalacrocorax atriceps behaviour using accelerometers (2009, background): “…Ryan et al. 2004, Weimerskirch et al. 2005) and some aspects of activity can be determined by using specific transducers (e.g. time depth recorders; Tremblay et al. 2003), tri-axial accelerometers permit an accurate quantification of any movement (even that which does not result in translocation)…”
Identifying foraging events in deep diving southern elephant seals, Mirounga leonina, using acceleration data loggers (2013, background): “This is because acceleration of the head during a prey encounter event is likely to be far greater in amplitude and much shorter in duration than acceleration signals produced during continuous swimming (Skinner et al., 2009).”
A comparison of indirect measures of feeding behaviour based on ARGOS tracking data (2007, methodology): “Specifically, there is a strong line of evidence to suggest dives with an active bottom phase flanked by a rapid ascent and descent are associated with feeding (Hindell et al., 1991; Simeone and Wilson, 2003; Kuhn, 2006).”
Central-Place Foraging in an Arctic Seabird Provides Evidence for Storer-Ashmole's Halo (2009, background): “Because most seabirds make relatively long foraging trips and return with many prey items, it is difficult to link specific dive bouts with particular prey (Simeone and Wilson 2003, Tremblay et al. 2005, Wilson et al. 2005).”
