As those of us in the northern hemisphere enter into the season marked by the longest nights and shortest days of the year, I can't help but reflect on the pervasiveness of light in our lives, despite the seasonal rhythms of darkness in the natural world.   In spite of these short winter days, or perhaps because of the long hours of darkness, Christmas is the best season in which to celebrate light.  For, it is at Christmas that we celebrate that: The people walking in darkness have seen a great light; on those living in a land of deep darkness a light has dawned.  Isaiah 9:2 Ironically, it is during the depths of the northern winter that nature treats us to some of its most conspicuous and glorious displays of light.   In the winter, we enjoy late morning sunrises and early evening sunsets.  Though our nights are long and cold, in clear weather they are filled with the brilliance of starshine and moonlight.  For those in the far north, this is t...

Can anyone really argue that there is a more iconic bird of Christmas in North America than the strikingly scarlet Northern Cardinal?  With brilliant crimson plumage that both matches red holly berries and contrasts beautifully with evergreen foliage and white snow, the cardinal seems to embody everything in the natural world that is beautiful in wintertime - and by extension, Christmastime.  (Check out this article for more reasons why the Northern Cardinal is the ideal emblem of Christmas.)  But, there may be more than one iconic winter bird out there that deserves to grace wintery Christmas cards and the December page of the calendar.   Join me in a little festive bird-related fun as I muse over a few additional species that I wouldn't mind seeing crafted into Christmas tree ornaments, shaped into sugar cookies, and emblazoned on Christmas sweaters! A somewhat wintery Northern Cardinal... in Texas.  Hands down, the most iconic bird of Christmas in North...

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 Situated along the western edge of the Gulf of Mexico, 113-mile-long Padre Island holds the distinction of being the world's longest barrier island.  South Padre Island, as the southern portion of the barrier island is known, is a renowned beach vacation destination, spring break hot spot, and (most importantly) the location of extraordinarily good birding, particularly during spring migration.   From late March through mid-May, birds migrating north from their wintering grounds in Central and South America to their breeding habitat in North America follow invisible yet ancient mig...

On the western slopes of the Sierra Nevada, the forests around 4,000 feet in elevation are excellent places to enjoy a wide variety of birds and other wildlife.  The mid-montane coniferous forests of this "lower conifer zone," as it is known, occur at elevations just above the oak woodlands and chaparral of the foothills, and just below the upper conifer zone.  Here, at this meeting place of plant communities, pockets of black oak and bigleaf maple mixed in among stands of ponderosa pines and other conifers add to the abundant species diversity.  Cooler, north-facing slopes hold stands of white fir, while live oak thrives in warmer, drier microclimates on south-facing slopes.  Sugar pine are common at this elevation as well, along with incense cedar and Douglas fir.   And, most importantly for birders, this zone of abundance offers an enticing mix of bird species from both lower and higher elevations.
