Curious how birds find their way? 🧭🐦
Analyze decades of ringing data to study abnormal migratory routes and uncover what these deviations can reveal about the mechanisms guiding birds on their journeys. Drop me an email for details! #ornithology

Bogong moths use a stellar compass for long-distance navigation at night - Nature Every spring, Bogong moths use the starry night sky as a compass to navigate up to 1,000 km towards their alpine migratory goal.

The Australian bogong moth uses the Milky Way as compass during annual 100-mile journey to cool caves. This is shown by a groundbreaking study also revealing that the Earth's magnetic field plays an important role in the navigation of this mysterious moth. www.nature.com/articles/s41...

Two hybrid Coenonympha species inherited most of their genome from one parent species but prefer mating with the other! By analyzing chemical profiles, we show that non-random trait sorting likely drives reproductive isolation, fueling hybrid speciation

A breeding ruff male (Calidris pugnax) in alert posture scans the breeding area for mating opportunities at Liminka Bay, Finland. Ruff males deploy one of three mating tactics that differ in aggressive and courtship behaviors. Differences in aggression between tactics are tied to concentrations of circulating androgens, which are modulated by the actions of a single gene.

A breeding ruff male (Calidris pugnax) in alert posture scans the breeding area for mating opportunities at Liminka Bay, Finland. Ruff males deploy one of three mating tactics that differ in aggressive and courtship behaviors. Differences in aggression between tactics are tied to concentrations of circulating androgens, which are modulated by the actions of a single gene.

A single gene underlies male mating morphs in ruff sandpipers, a new Science study finds. The results show how evolutionary changes in a single gene's structure, sequence, and regulation can drive significant diversity within a single species.
