Required tools to capture emperor penguins.
(A) An adult-chick pair inside the corral. (B) A 3 m long bamboo stick at the top, one of the panel of the corral (a 50 cm ruler is placed just above it to facilitate scaling) in the middle, and the crook at the bottom. The crook is the right extremity of the pole while the left extremity is a hook.

Pictures of the different deployments performed.
(A) Adult emperor penguin equipped with back-taped loggers (a TDR in the middle of the back and a GPS underneath). The green line on the bird’s belly is non-permanent marking. (B) Adult emperor penguin equipped with back-glued loggers (an accelerometer in the middle of the back and ARGOS satellite transmitter underneath) and a leg-banded logger on its right foot. (C) Juvenile emperor penguins both equipped with a back-taped-epoxied logger.
