In the mid-1990s I wrote a column about the Pacific golden plover, Oahu’s favorite shorebird, known here as kolea. Soon after, I received in the mail several journal articles about these birds from ornithologist Oscar Wally Johnson of Montana State University. Someone had mailed Wally a copy of the column, and though we had not met, he sent me his publications.

“Nice piece on the kolea,” he wrote. “I think you’ll find these interesting.”

And so began a 20-year (and counting) friendship among Wally, me, the kolea and their many admirers.

As his research revealed more and more of this bird’s astonishing capabilities (flying, for instance, 3,000 miles nonstop in three days while occasionally reaching 100 mph in favorable wind), Wally began giving annual talks on Oahu.

Readers of this column increasingly emailed me questions about the kolea they saw in their yards, parks, golf courses and streets. I would email Wally the questions, he would email back the answers and I would write another kolea column.

Finally, last year, when Wally’s Oahu lectures were drawing standing-room-only crowds, and my kolea email became so abundant it got its own folder, we decided it was time to write a book.

The University of Hawai‘i Press agreed. Wally and I worked together to put his scientific articles into everyday terms and illustrate them with his photos and maps. As a result, he and I recently became the proud co-authors of “Hawaii’s Kolea: The Amazing Transpacific Life of the Pacific Golden-Plover.”

Wally, an affiliate research scientist at Montana State, became fascinated with kolea in 1979 while working in the Marshall Islands, and has been studying them since. His research continues to take him from his home in Bozeman to Hawaii, Alaska and throughout the Pacific.

Wally is the undisputed world expert on Pacific golden plovers.

The book contains pretty much everything everyone knows about kolea, and as you would expect, Wally’s photos during his 38-year pursuit of kolea facts are out of this world.

Before his death in 2006, Bob Krauss of The Honolulu Advertiser chronicled the comings and goings of Oahu’s kolea. I never met Bob, but I read his columns and am happy to accept the title that many readers have bestowed upon me: the new Bob Krauss. My kolea email is now more numerous than all my other column subjects combined.

The Hawaii Audubon Society is a longtime supporter of Wally’s kolea research. You can help Hawaii’s plovers and other native birds by buying the book from that nonprofit organization. Go to hawaii audubon.org/store.

Have a kolea Christmas.
