Auditory Archive: Yellowhammer dialects across two countries and 100 years
from Fledgling Theories · host Ellie Roark & Willson Gaul
Roughly 100 years ago, some Yellowhammers (Emberiza citrinella) were captured in England and released in New Zealand. They successfully bred there, establishing a new population. Since then, what has happened to the way these birds sing? How has 100 years of separation between the New Zealand and Great Britain populations affected the dialects of Yellowhammers that live in each of these places? And why do bird dialects matter? Jump in to the world of bird song with us as we discuss "Dialects of an invasive songbird are preserved in its invaded but not native source range" (Pipek et al, 2018).
