Meet Sorrel: The Hen Harrier Defying Extinction

Sorrel, a hen harrier tagged a decade ago in southern Scotland, stands out as an exceptional bird due to her prolonged survival and continued tracking. While most of her peers succumb to death, are killed, or disappear, Sorrel has not only survived but also traveled extensively and fledged more than a dozen chicks.

Her ongoing presence provides vital data for understanding and protecting hen harriers, a species listed as red-threatened due to low population numbers and historical persecution. Hamish Smith, a BTO ringer, notes that every surviving breeding female is significant in a species facing severe conservation pressures. Sorrel's story underscores the value of dedicated conservation efforts and collaboration among various stakeholders.

Since 2016, Sorrel's movements have spanned diverse landscapes including uplands, moorlands, coastal areas, and islands, even crossing the Irish Sea. Her migratory patterns reveal essential information about habitat use and seasonal movements, which would otherwise remain unknown without satellite monitoring. This long-term data is crucial for addressing ongoing challenges such as habitat pressures, nest failure, food scarcity, severe weather, and illegal persecution.

Sorrel's extensive travels have also fostered connections among conservationists, raptor workers, volunteers, land managers, and local communities across Britain and Ireland. This collaborative approach enhances the understanding of hen harrier behavior and vulnerability, ultimately contributing to better protection strategies for this iconic bird of prey and potentially improving survival rates for other birds.
