Central Texas · Edwards Plateau · federally permitted

USFWS-permitted for the bird that only nests in Texas

The golden-cheeked warbler nests here and nowhere else on earth. Habitat assessments and nesting bird support are available year-round; federally permitted protocol surveys run March 15 through June 1 and should be scheduled well in advance.

How to hire me

Two ways to bring me onto a Texas project

Hire Travel Twist Biologist directly for site-specific work, or add me to an established consulting or engineering team as an insured biological subcontractor.

01 — Consulting and engineering firms

Bring in experienced biological capacity

Bring me in for seasonal, overflow or specialist assignments. I can lead or join field efforts, work within your safety, data and QA/QC systems, and carry work through final reporting.

02 — Landowners and developers

Start with the biological question

If a project may affect warbler habitat or nesting birds, I can review the site, document field conditions, explain the practical next step and coordinate with your project team.

Travel Twist Biologist provides biological consulting and recommendations—not legal advice, permits, regulatory clearance or agency decisions.

Big enough for both

Texas has room to build—and room for wildlife. Consulting with a qualified biologist helps teams solve problems and keep good projects moving forward.

When to call

Plan around the field season

01 — Year-round

Screen the site and define the scope

Desktop review, golden-cheeked warbler habitat assessments, project planning and nesting bird support can begin before construction or survey season.

02 — Before spring

Reserve warbler survey capacity

If a golden-cheeked warbler presence/absence survey may be warranted, early planning protects the limited spring field window.

03 — Active projects

Add field or reporting support

Construction monitoring, reconnaissance, GPS data collection and technical documentation are available by project scope.

How I work

Founder-led. Built to scale by project.

I'm Elizabeth Hingle: seven seasons on the golden-cheeked warbler, fifteen-plus years of avian work, and field experience across fifteen states. I remain the client and technical lead while qualified field or GIS support can be coordinated when a project needs a larger team.

You get direct senior-level communication, field leadership, QA/QC and final reporting, with the team matched to the scope.

Banding and nest work pictured was conducted under the monitoring program's permit. My own federal recovery permit authorizes golden-cheeked warbler presence/absence surveys and habitat assessments.
