I took a rather indirect route from Tucson to northern Nevada to help my dad celebrate his birthday this summer, starting in New Mexico, staying a couple of nights in northern Arizona, then southern Utah and finally central Nevada (see Mountain Melody) before driving the final stretch. My route home was almost as indirect (see […]

I discovered another of Nevada’s hidden gems recently. In early July, I traveled from southern Arizona to northern Nevada, dodging wildfires and thunderstorms, and ended up in a lovely little canyon in the Toquima Range. Not far from the geographical center of Nevada, Pine Creek Campground is a gateway to the 11,000 foot crest of
I just finished reading Gordon Hempton and John Grossman’s book, One Square Inch of Silence, about Hemptons’ attempt to preserve the quiet of the Hoh rainforest in Olympic National Park, Washington. Hempton is an Emmy-winning nature recordist (yes, it’s possible!) who has traveled the world seeking not only natural sounds, but quiet landscapes. Three trips

In my many years of wandering around the mountains, I’ve come across a few canyons where the echoes sound distinctly like human voices, in conversation, somewhere else in the canyon. No one is there, it’s just the reflections of the gurgles of the creek, usually. I’ve run into this sensation along Eagle Creek in Wyoming,
Around the world, during the warmer months, the beginning of the day is heralded by bird melodies. But in addition to being wonderful alarm clocks, the dawn chorus reflects how birds have adapted their singing to both ambient conditions and interspecific competition. Most bird song is for territory defense and attracting mates (female birds often

It seems as if every mountain range in the southwest has had a huge wildfire in the last decade or so. Millions of acres burned, forests charred, ecosystems altered. If the drought continues, it may be millennia before some of the dryer, south-facing slopes see a forest again. The Horseshoe 2 fire burned in the

A recent article in BBC News Magazine highlights some fascinating research being conducted on how tuned in we are to bird song. People find birdsong relaxing and reassuring because over thousands of years they have learnt when the birds sing they are safe, it’s when birds stop singing that people need to worry. Birdsong is

It whispers, gurgles, laughs and chortles, this sliver of a creek flowing north from Mexico toward the Gila River. On this lovely day in April, the San Pedro River still flows through the sandy banks, but within a month or so it will begin to dry up, except for isolated pools and stretches near the

Four species of doves nest in my neighborhood – Mourning, White-winged, Inca, and Eurasian Collared doves. The most common nests are those of Mourning Doves. Last spring, a pair decided to build their flimsy stick nest on top of the porch light right outside my front door. They’ve tried this in years past, but usually

Spring has finally arrived in the mountains of southern Arizona. Little flowers are starting to appear, and birds are starting to sing. Last week I took one of my favorite hikes in the Huachuca (wa-choo-ka) Mountains, up to Blacktail Pond. It’s a steep hike up a very rocky road, but the views of the surrounding

Much of sound editing and analysis, particularly for animal sounds, is done using spectrograms. Spectrograms are graphs that show the frequency (or pitch) on the y-axis and time on the x-axis. The loudness of the sound is indicated by the intensity of the color. They read somewhat like a musical score, except that time is

It’s a cute little bird – the Phainopepla. A member of the tropical Silky Flycatcher family, males are a shiny black and females a charcoal grey. Both have red eyes and a feathery crest. They are quite noticeable in the desert, as males like to perch at the very top of mesquite trees (like the
