Loggerhead sea turtle policies of the Barack Obama Administration (2009-2017) gear in the loggerhead conservation area during the presence of El Niño conditions in order to protect the endangered North Pacific Ocean loggerhead DPS. This ruling effective July 23, 2014 was intended to prevent bycatch of loggerhead sea turtles. A team including sea turtle biologists and oceanographers determined the presence of El Niño conditions based on the “El Niño watch” issued by the Climate Prediction Center (CPC), anomalies found in sea surface temperature (SST) charts published by NOAA’s Coast Watch Program, the presence of loggerhead sea turtles in the Pacific loggerhead conservation area, and reports of loggerhead strandings.

Loggerhead shrike be energetically stressed and underweight. Insects are consumed in mid-flight, but vertebrates usually require more handling time and therefore more energy. Due to the shrike's small size in proportion to the size of its prey, it must rely on specialized adaptations to facilitate its hunting. The powerful, hooked beak of the loggerhead shrike allows it to sever the neck of a small vertebrate. Larger prey are subjected to impaling, in which they are pushed down into a sharp projection, such as a thorn or barbed wire. The bird can then tear off flesh by using the projection as an anchor.
