Researchers from the British Trust for Ornithology (BTO) have used data gathered by volunteers to uncover how the decline in one Red-listed species is linked to climate-induced changes in its breeding behaviour. The open-access findings of their study have now been published in the journal Biology Letters. Willow Warblers are small, tuneful birds that breed across Europe...
New research from BTO implicates rising temperatures in the steep decline of the Willow Warbler, one of the UK’s most tuneful harbingers of spring. The study, published in the journal IBIS, shows that Willow Warblers are doing better in Scotland, where temperatures are cooler. Evidence is building to suggest the population in southern Britain is a casualty of recent anthropogenic climate change.
