- In Vietnam, Eurasian wrynecks are commonly seen in the northern and southern regions during the winter months.
Role in the Ecosystem:
- Eurasian wrynecks play a crucial role in controlling ant and termite populations in nature.
- They also contribute to the overall biodiversity of the ecosystem.
Conservation Status:
- Eurasian wrynecks are classified as Least Concern by the IUCN Red List.
- However, their numbers are showing signs of decline due to habitat loss and pesticide use.
