Bird Nest Surveys & Field Assessments in Ontario

When a bird nest survey is needed

Bird nest surveys are commonly requested for projects involving:

• Tree removal, pruning, or vegetation clearing
• Residential, commercial, or industrial construction
• Demolition or site redevelopment
• Land grading and excavation work
• Infrastructure and utility projects (roads, hydro, fiber, pipelines)
• Municipal maintenance or right-of-way clearing
• Any work scheduled during spring or summer breeding seasons

Many bird species in Ontario are active nesters during these periods, and disturbance to active nests can significantly impact project timelines.

What we do on site

Our biologists conduct field-based bird nest surveys and habitat observations prior to construction or vegetation disturbance.

We assess:

• Presence of bird activity and potential nesting behaviour
• Active nests when visible or detectable
• Bird species identification where possible
• Habitat conditions and suitability for nesting
• Areas of elevated ecological sensitivity

Surveys are conducted using visual and auditory field methods combined with professional ecological judgment.

Why bird nest surveys matter in Ontario

Bird nesting activity is highly seasonal, and many species are protected while actively nesting. Disturbance during this period can lead to:

• Unplanned construction delays
• Work stoppages during sensitive periods
• Regulatory or permitting complications
• Increased project risk during peak breeding season

A pre-construction field survey helps identify potential issues early so you can plan site activity more effectively.

Who we work with in Ontario

We regularly support field assessments for:

• Construction contractors and builders
• Real estate developers and landowners
• Municipal and infrastructure projects in Ottawa and Eastern Ontario
• Utility and corridor maintenance teams
• Forestry and land management operations

Seasonal timing in Ontario

Bird nesting activity in Ontario typically peaks in spring and early summer, making this the highest-risk period for construction delays due to wildlife protection rules.

If your project involves vegetation clearing or demolition during this period, a pre-construction survey is strongly recommended before work begins.

Bird nest surveys in Ottawa and across Ontario

We provide bird nest surveys and biologist reports throughout:

• Ottawa
• Eastern Ontario
• Greater Toronto Area (GTA)
• Surrounding rural and development regions
