Map: Eurasian reed warbler breeding range (green) in Europe and variation in the geomagnetic signature (total magnetic intensity, magnetic inclination and magnetic declination). The natural ...

Eurasian reed warblers (Acrocephalus scirpaceus) appear to calculate their geographical position by drawing data from different distances and angles between magnetic fields and the Earth’s shape.

Research by Bangor University found that these birds, in this case, Eurasian reed warblers (Acrocephalus scirpaceus) use only the Earth's magnetic inclination and declination to determine their ...

A loud burst of song from a Blackcap deep in the undergrowth is a sign that Spring has finally arrived. The songs are so similar that the two species respond to the other, with the Blackcaps ...
