Where field guide
meets fieldwork.

Henry has spent the better part of a decade in the field — leading public excursions for the Yolo Bird Alliance, documenting species along the Pacific Flyway, and chasing rarities across six continents.

Based in California, his work moves between two registers: the patient, methodical observation of a working ornithologist, and the eye of a photographer trained to find the singular moment in a thousand. Recent assignments have taken him from the wetlands of West Sacramento to the cloud forests of the Andes — anywhere a bird is worth waiting for.

He works with private landowners, nature preserves, vineyards, lodges, and family estates to survey local avifauna, advise on habitat improvement, and produce documentation worth keeping — field guides, portfolios, and placards rendered with the same care as the photographs themselves. He also takes a small number of private touring clients each season, both at home and abroad.

Field notes,
kept carefully.

A small selection from the working archive. The full catalog spans wetland, alpine, pelagic, and tropical environments.

The fastest way to know a place is to ask its birds — they have lived there far longer than we have.
