Cover: Northern gannet (Morus bassanus) from Rouzic Island, France. During a trip at sea, northern gannets alternate between periods of foraging with active food searching and periods of travelling. Amélineau and colleagues (pp. 876−885) validated a long-lasting optimal foraging theory, predicting that a tortuous trajectory is more costly than a linear one due to additional mechanical costs. Northern gannets had higher energy expenditure per minute during tortuous foraging flight than during more linear travelling flight. Wind speed and direction also influenced energy expenditure, yet birds did not take full advantage of wind conditions during foraging trips, due to prey distribution and wind predictability.

The conference will incorporate the JEB Symposium Sensory Perception in a Changing World and the SEB satellite meeting. Find out more and register to join us in March 2025 in Liverpool, UK. Submit your abstract by 17 January 2025. Early-bird registration ends on 17 January 2025.
Extraordinary creatures: mantis shrimp
In our new Conversation series focusing on extraordinary creatures, Tom Cronin and Sheila Patek tell us about the incredible biology of mantis shrimp, from their complex vision to their powerful striking abilities.
Behaviour as a physiological process
In this Commentary, Shamil Debaere & colleagues argue the case for integration of behaviour into animal physiology, and advocate for behaviour to be considered as a physiological process.
Tiny ring-necked snakes keep warm heads despite their size
Some ectotherms are able to raise the temperature of certain body parts above the temperature of other regions & now Christian Fox and Albert Chung, with undergraduates from the University of Virginia, reveal that the heads of tiny ring-necked snakes can be 2.1C warmer than their tails, even though they are only 20cm long.
