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 … Continue reading

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 … Continue reading

Modelling collective navigation via non-local communication

A recent paper called “Modelling collective navigation via non-local communication”has been published by S. T. Johnston(1) and K. J. Painter(2). They tell us that a group of individuals produce better navigational results thanindividuals which is why flocks of birds are … Continue reading

New Study Fuels Debate About Source of Birds’ Magnetic Sense

This link gives you a very good overview of the latest arguments about whether Cryptochromes,  which are sensitive to magnetic fields and exist in the eyes of birds, help with their navigation.  All the great and good involved in this … Continue reading

Cuckoo Migration, a theory 2021

In January 2021 I had the opportunity to have another test of my theory that migratory animals (fledgling cuckoos) use an innate sense of direction to find their way to their destination. I did a zoom presentation to some of … Continue reading

Magnetoreception – the ability to sense the Earth’s magnetic field

David Keays is one of the mega stars of animal navigation research and has spent a life time trying to work out how magnetism might work. Here is a summary of his latest work: Magnetoreception is the ability to sense … Continue reading
