Which Wryneck species is described as having a diet even more narrowly focused, being almost entirely ants year-round?
Answer
The Red-throated Wryneck (*Jynx ruficollis*)
While both recognized species of the *Jynx* genus share the specialization for ants, differences arise from their residency status and geographic separation. The Red-throated Wryneck is a non-migratory resident across much of sub-Saharan Africa. Due to this stable environment, its diet exhibits less plasticity than its migratory counterpart, being described as even more narrowly focused and consisting almost entirely of ants throughout the entire year. This suggests a very stable and consistent local availability of this primary food resource where it resides, unlike the Eurasian species which must maintain some dietary adaptability to support migration.
