Chestnut Bunting vs Tristram's Bunting

In short

Chestnut Bunting and Tristram's Bunting can be tricky to distinguish, especially in non-breeding plumage. The most reliable field mark is the chestnut coloration in Chestnut Bunting males, which is absent in Tristram's Bunting. Both species have similar structure, but their habitat preferences and subtle plumage differences can aid identification.

Identification tips

• Look for chestnut coloration in males for Chestnut Bunting.
• Check for a darker facial pattern and distinct supercilium in Tristram's Bunting.
