Extended Data Fig. 9: The parapatric distributions and contact zones of the fulvettas.
From: Hybridization mitigates climate change risk in mountainous birds
The ranges of fratercula, davidi, and hueti are delineated by black outlines. Putative contact zones, inferred from genetic admixture analyses, are highlighted in blue shade, with a putative hybrid zone marked in red outline. It is important to note that these inferred zones are dependent on the current sampling design and may represent underestimations of the true areas of sympatry. Species distribution ranges produced by BirdLife International and Handbook of the Birds of the World from the IUCN Red List of Threatened Species (https://www.iucnredlist.org/species/22716644/94504173).
