While it's always fun to come across any indication of a beaver's presence in the landscape , without a doubt seeing one of these amazing creatures in the wild is much more exciting!  Here in California's Central Valley, I've found those sightings to be rather rare - and therefore all the more special when they do occur.  While I regularly come across signs of beaver activity , such as felled trees, gnawed branches, dams, lodges and tracks, it's less frequent that I get to spend time watching these critters go about their daily business.  So, when I came across this beaver on a small reservoir in the foothills, I savored the experience.  Any moment with a beaver is an excellent opportunity to sit quietly beside the pond, watch and learn! American Beaver in a small reservoir in the foothills of the Sierra Beavers are best known for their sturdy dams, which they construct of logs, sticks and mud.  These dams are placed across streams and other areas of flowing wa...

Worldwide, wetlands are among the most species-rich habitats on our planet, home to a wealth of birds and other wildlife.  Open water of varying depths, with emergent vegetation alongside mudflats bordered by diverse plant communities, including forest edge and grassland, typically make wetlands and adjacent habitat absolutely ideal homes for a high concentration of wildlife in a relatively small space.  It's no coincidence that around the world, many of the nature reserves and preserves that have been set aside as protected habitat for wildlife are wetlands . Singing Reed Bunting at Rainham Marshes In the UK, this protected habitat is often administered by the Royal Society for the Protection of Birds, or the Wildlife Trusts.  (If you are in the UK, I highly recommend checking out the map tool on their respective websites to find  an RSPB reserve  or a Wildlife Trust nature reserve to visit near you!  There are so many to choose from!) As we planned our t...

Summer is upon us, and with any luck, that means vacation.  For those of us who love nature and the great outdoors, that usually means traveling to visit North America's beautiful National and State Parks.  And for the binocular-toting crowd in particular, an experience in the outdoors is not complete without a few memorable encounters with the wonderful wild animals that call these places home.  Visit any National Park in North America and a traffic jam is sure to mean one thing: Wildlife.  (Or, possibly, lack of parking spots.  But hopefully it's wildlife.)  A critter pauses along the roadside anywhere from Acadia to Joshua Tree, and all the break lights flash on. We can't help ourselves.  Wildlife enthralls us. I roll my eyes at tourists who stop their cars in Yosemite Valley to gawk at Mule Deer, a common, ho-hum species here in the West.  Yet when we visited Great Smoky Mountains National Park last year, I did the exact same thing when I sp...

Tucked away in the southeastern corner of California is an ecosystem like no other: the vast Mojave Desert. While it may not look like much to passing motorists, the arid Mojave Desert is brimming with wildlife.  Birds, mammals, reptiles, insects: It's all here, thriving against the odds in an undeniably harsh environment.  Cold winters bring snow flurries to high elevations as temperatures drop well below freezing, and summer highs can soar to more than 120 degrees Fahrenheit, baking the desert pavement.  The wind is fierce and rainfall is minimal all year, a scant three to nine inches annually.   Clearly, living conditions are tough. Yet despite the odds, here in these wide open spaces lives a very special suite of characters, all perfectly designed to make the most of life in this inhospitable place.   This is the wildlife of the Mojave Desert. Last week, we spent a couple of days exploring Mojave National Preserve, enjoying lovely desert scenery an...
