Oregon is home to a diverse array of bird species, many of which rely on trees for nesting and breeding. For tree care professionals, understanding how bird nesting impacts pruning, removal, and general tree maintenance is essential to balancing ecological responsibility with property management.
Bird Nesting and Tree Care Regulations
Federal and state laws protect many nesting birds in Oregon. The Migratory Bird Treaty Act (MBTA) prohibits the disturbance of active nests containing eggs or young. In addition, the Oregon Department of Fish and Wildlife (ODFW) enforces guidelines that further protect certain species, particularly raptors like bald eagles, ospreys, and hawks. Tree care companies must be aware of these regulations to avoid legal repercussions and protect wildlife.
Seasonal Considerations for Tree Work
The nesting season for most birds in Oregon runs from March through August, with peak activity occurring in the spring and early summer. Sperry Tree Care works with clients to schedule pruning or removals outside the nesting season when nests would be at risk.
Common Nesting Birds in Oregon’s Trees
Several bird species commonly build nests in Oregon’s urban and forested trees, including:
- American Robin – Found in both urban and rural trees, nesting from April to July.
- Northern Flicker (Woodpecker) – Prefers dead or decaying trees for nesting cavities.
- Western Bluebird – Often nests in hollows or old woodpecker holes.
- Osprey – Builds large stick nests in tall trees, especially near water sources.
- Bald Eagle – Constructs massive nests, sometimes reused for decades. These nests require special protection and buffer zones.
Bird nesting season adds an extra layer of complexity to tree care in Oregon, but with careful planning and adherence to wildlife protection laws, we can ensure the safety of both trees and the birds that depend on them. By respecting seasonal timing, conducting thorough inspections, and following best practices, we can balance tree maintenance with conservation efforts, contributing to Oregon’s rich and diverse ecosystem.
