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...

The other day, while exploring one of the remaining patches of wetlands around my county, I came across a furry little critter that was a complete surprise for me: an American Mink!  Contentedly going about his (or her) business at the edge of the wetland, staying under the dense cover of an old clump of willows, the mink slipped out of sight before I was able to get a photograph.  But this mink sighting got me thinking about other mammals I've encountered here in California's Central Valley, and as it turns out... there have been quite a few!   California Ground Squirrel: A common sight in the Valley, and an important part of the ecosystem! Though the Central Valley is no longer the land of wild abundance it once was (at least not in terms of wildlife), more species of mammals than one might imagine still manage to make their living on the fringes of urban and agricultural land up and down the valley.  National Wildlife Refuges provide much-needed havens for a ...

During the first week of April, Eric and I spent six amazing days birding in South Texas, starting in the McAllen area and ending on South Padre Island.  Follow along with our journey here: Part I: Lower Rio Grande Valley Thornscrub and Woodland Part II:  Coastal Prairie and Thornscrub Part III:  Gulf Coast Wading Birds Part IV:  South Padre Island Neotropical Migrants One of the most famed birding destinations in North America, the Lower Rio Grande Valley of South Texas enjoys a warm subtropical climate where plant communities found nowhere else in the U.S. thrive.  Here, elements from the Chihuahuan Desert to the west and the coastal prairies to the east blend, meeting along the Rio Grande River where Tamaulipan thornscrub and subtropical woodlands once flourished.  Due to this unique climate and combination of habitat types, an impressive list of bird species native to Mexico and farther south extend their range north across the border into the southern...
