What specific habitat is the Kirtland’s Warbler (Setophaga kirtlandii) critically dependent upon?
Answer
Young jack pine forests
The Kirtland’s Warbler, scientifically named *Setophaga kirtlandii*, serves as a prime example of the specialized niche adaptations found within the Parulidae family. Its survival is intrinsically linked to a very specific type of environment: young jack pine forests. This dependency highlights how detailed specialization can occur even within a highly successful and diverse lineage like the New World warblers. The structure and composition of these young pine stands are essential for its breeding success, contrasting sharply with the more general foraging habits seen in many other warbler species.
