Christy Yuncker Photo Journal
Welcome to the Christy Yuncker Photo Journal.
This webpage and photo galleries developed from fascination with Sandhill Crane behavior. Since 1999, we have documented the behaviors of the same crane pair, from morning to sunset, through their Alaska nesting season.

Crane stature and voices are arresting; their dancing is flashy and elegant. Cranes have long been venerated in many ancient cultures.
Cranes are long-lived and learn from experience. With each passing year, they progressively improve their survival skills. Only after Alaska cranes migrate north and south several times do they select their mates.
The bonded pair can reproduce for 15 years or more. They return in April to an ice-covered pond for a month of nesting and then three months of teaching young colts to forage, to dance, and to fly in time to escape the return of winter. We are particularly intrigued by nurturing, by social interactions, and by crane mental capacities.
Crane-watching helps us replace 21st century hubris with awe for the subtlety of evolutionary outcomes. It provides insights into our shared biological origins and increased respect for fragile global ecosystems.
Two blogs complement this site:
- Alaska Sandhill Crane Blog reviews crane biology,
and - How birds think reviews diverse scientific literature and offers perspectives on the avian brain, its capacity, and behaviors it controls.

Why this website?
After we moved from Vermont to 40 acres of taiga in Interior Alaska, we found that a pair of Sandhill Cranes had prior claim to our sphagnum/sedge/cranberry bog. Google satellite views of the habitat are shown on this website.
We have been privileged to watch these Goldstream Valley cranes for over a decade. This photojournal and the Alaska Sandhill Crane Blog grew from our acquaintance with the crane pair whom we know as Millie and Roy.
Cranes are statuesque, sometimes boisterous, and often secretive - iconic inhabitants of grasslands and marshlands in Eurasia, Africa, Australia, and North America. Year upon year, Alaska Sandhill Cranes fly thousands of miles, evading powerlines and shotguns and surmounting natural barriers, to reach their nest sites. In contrast to some non-migratory crane populations that become habituated to humans, most Alaska cranes are wild and wary.
Once at their summer destinations, Alaska cranes explore the surroundings, defend their territories, make nests and raise young, broadcast their presence over miles by resonant bugling, and interact at closer distances by soft purring and acrobatic dancing. With observations, photographs, and an evolutionary neuroscience pespective, we focus on:
- the education of crane colts in the wild,
- information content of the signals that bind cranes to one another,
- social structure within breeding neighborhoods and flocks, and
- how they make decisions.
This website and its companion Blog are intended to be an information resource and, we hope, a catalyst for discussions of crane biology, bird behavior, and animal cognitive capacities. Please email us with your own observations and ideas so that we respond and share your insights on the web.
Thank you for making Nature an immediate part of your personal world view.
