Bird Navigation
Bird navigation is a fascinating and intricate process that involves a variety of sensory and cognitive abilities. Discover the science behind how birds find their way during long-distance migrations, including the role of visual, magnetic, olfactory, and celestial cues. Learn about the amazing adaptations that birds have developed to navigate different environments and conditions, from Arctic tundra to tropical rainforests. Explore the practical applications of bird navigation research, including conservation, aviation, and robotics. Discover our resources and expert insights on bird navigation and expand your understanding of one of the most extraordinary abilities in the animal kingdom.

Magnetoreception and the ruling hypothesis
This paper is fascinating. This site has always been sceptical about Magnetoreception – the magnetic navigation story for the same reasons that are discussed here. No-one has found the magnetic receptors. the cryptochrome story requires conditions in the eye that are not conducive to quantum effects and knowing where North is does not help without…

A conceptual framework on the role of magnetic cues in songbird migration ecology
This paper is difficult to understand but it summarises the work on animal navigation to date. The key is that all the research which is confident that animals navigate using magnetic cues are not necessarily the whole story and that all navigators use all the clues they can get to help them. Recently there was…

Light pollution is important
Atchoi, E., Mitkus, M., Vitta, P., Machado, B., Rocha, M., Juliano, M., Bried, J. & Rodríguez, A. 2023 Ontogenetic exposure to light influences seabird vulnerability to light pollution. Journal of Experimental Biology 226. doi: 10.1242/jeb.245126. Atchoi 2023 (no pdf) Light pollution critically affects the fledglings of burrow-nesting seabirds, leading to massive mortality events. The successful management of this pollutant depends…

How young animals learn to migrate
While advances in biologging have revealed many spectacular animal migrations, it remains poorly understood how young animals learn to migrate. Even in social species, it is unclear how migratory skills are transmitted from one generation to another and what implications this may have. Here we show that in Caspian terns Hydroprogne caspia family groups, genetic and foster…

Olfactory landmarks and path integration converge to form a cognitive spatial map
This paper on olfactory landmarks is interesting as it covers the idea that the distinctive smell of a place can help navigation by creating a new landmark for helping an animal navigate. The recognition of a spatial landmark by its sensory features poses a problem for neural circuits. Fischler-Ruiz, et al. show how this problem…
