I had to wait 14 years to finally see one in the wild...
It was on my very first trip to the Hawaiian Islands that I started paying attention to birds, in large part because of the presence of a Hawaiian Hawk, or 'Io, at the Hilo Zoo. It immediately raised questions, mainly, how in...

When the Polynesians first arrived in the Hawaiian Islands, it might not have been a natural paradise. Some of them lived directly in the path of all-to-common lava flows (and still do today). We explore the Pu'u Loa petroglyphs on Chain of Craters Road in Hawai'i Volcanoes National Park.
The southeast coast of the Big Island of Hawai'i is a barren blasted land. One can blame it on the lack of rain, but though it is arid, rainfall is plentiful enough to support forests nearby. One only needs to look up the Hol...

Impressed with fire walkers? We walked across a lake of fire, at a place called Little Source of Great Spewing in Hawai'i.
Kilauea Iki eruption in 1959. The prevailing winds caused debris to pile up behind the fountain, forming the Pu'u Pau'i cinder cone. Source: US Geological Survey Kilauea is one of the five major shield volcanoes making up the...

"What ... is that?"

"The State of Hawaii."

"Not good. That is not good."

I've seen Kilauea a number of times, but nothing prepared me for what we would see in the darkness.
The ongoing eruptive activity at the summit caldera of Kilauea on the Big Island of Hawai'i. You aren’t hearing this from me (well, okay, you are), but sometimes teaching is just a little bit like carnival barking. You have t...

Tonight was a unique astronomical event, a Strawberry Moon on a summer solstice, the first since I was a child back in 1967. There's nothing significant in this other than human number-keeping, but it seemed as good an excuse...

There's only one kind of rock in the Hawaiian Islands (not counting coral), but it comes in many guises. We continue our journey through the Hawai'i That Was.
There are lots of places that are associated with a particular kind of rock. There's the granite of the Sierra Nevada, or the sandstone of Zion National Park. Geologists think Franciscan graywacke sandstone when someone menti...

Better get the sheriff out there and tow that abandoned pahoehoe away.

Mauna Loa from the Mauna Kea Road near the Onizuka Center The answer is easy: clouds. This whole post is a temper tantrum, a tantrum that resulted from the fact that we were on the Big Island of Hawai'i, the site of the bigge...

Hawaii's most active cone is more or less invisible from anywhere on the ground. Here it is from the air (2009). If you are headed to the islands soon, there is a new lava flow three miles long this month.
The Pu'u O'o cone from above Hilo Disclaimer: This is NOT happening right now! These pictures are from 2009. Pu'u O'o is the invisible volcano on the Big Island. It's been the center of eruptive activity for much of the last ...

There is a cooing sound that starts the day in the lowland towns of the Hawaiian Islands. It doesn't take long to identify the singer: it's the Zebra Dove (Geopelia striata). Even if one misses their morning song, they'll ma...

It is quite literally the first bird you will see as you emerge from the airplane when you land anywhere in the Hawaiian Islands. They certainly look tropical and exotic at first, but as you go along in your travels, you will...

Meet what is probably the most numerous land bird in Hawai'i, for better or worse. The problem of invasive species on the islands.
Bird-watching in Hawai'i can be frustrating. There are a great many colorful and easily seen birds, and there is the quandary of knowing that most all of them are introduced and invasive species. The native birds are rarely s...

Why should we care when there are luaus, shopping and surfing to do?
Lapakahi State Park on the Big Island is the remains of an ancient fishing village that was occupied for hundreds of years. Not a single plant in the picture is native to Hawai'i. In a lot of ways, a post like this is how one...
