Foraging Responses of Black-Legged Kittiwakes to Prolonged Food-Shortages around Colonies on the Bering Sea Shelf

Creator:

Paredes, Rosana, Orben, Rachael A., Suryan, Robert M., Irons, David B., Roby, Daniel D., Harding, Ann M. A., Young, Rebecca C., Benoit-Bird, Kelly J., Ladd, Carol, Renner, Heather, Heppell, Scott, Phillips, Richard A., and Kitaysky, Alexander

Abstract:

We hypothesized that changes in southeastern Bering Sea foraging conditions for black-legged kittiwakes (Rissa tridactyla) have caused shifts in habitat use with direct implications for population trends. To test this, we compared at-sea distribution, breeding performance, and nutritional stress of kittiwakes in three years (2008–2010) at two sites in the...

Prey Patch Patterns Predict Habitat Use by Top Marine Predators with Diverse Foraging Strategies

Benoit-Bird, Kelly J., Battaile, Brian C., Heppell, Scott A., Hoover, Brian, Irons, David, Jones, Nathan, Kuletz, Kathy J., Nordstrom, Chad A., Paredes, Rosana, Suryan, Robert M., Waluk, Chad M., and Trites, Andrew W.

Abstract:

Spatial coherence between predators and prey has rarely been observed in pelagic marine ecosystems. We used measures of the environment, prey abundance, prey quality, and prey distribution to explain the observed distributions of three co-occurring predator species breeding on islands in the southeastern Bering Sea: black-legged kittiwakes (Rissa tridactyla), thick-billed...
