Bell's Sparrows

Earlier in April, during our visit to Carrizo Plain, I was interested in more than just the beautiful wildflowers; I had my eye on a few bird species as well.  In addition to more flashy Horned Larks and Lark Sparrows, little Bell's Sparrows (Artemisiospiza belli) also caught my attention (and offered some good photo opportunities!)


Prior to 2013, the Bell's Sparrow and similar Sagebrush Sparrow (Artemisiospiza nevadensis) were considered a single species, the Sage Sparrow.  The two species are best distinguished by their range. Sage Sparrows have a larger range, which covers much of intermountain west; they can be found year round in the sagebrush lands of the Great Basin.  The range of the Bell's Sparrow overlaps with that of the Sagebrush Sparrow in eastern California, especially during the winter, and the two species can be very difficult to tell apart.  During the breeding season, Bell's Sparrows can safely be identified on their breeding grounds in coastal California and Mojave Desert.


Like many other sparrows, Bell's Sparrows can be quite inconspicuous as they spend much of their time foraging on the ground beneath shrubs for insects and seeds.  But during the breeding season, especially in the morning, males have a habit of perching on top of shrubs in the open to sing.  The male Bell's Sparrow's song was what initially attracted my attention to these lovey little birds.


Bell's Sparrows prefer shrubby habitat, such as sagebrush scrub and coastal chaparral.  Saltbushes (Atriplex sp.) and sagebrushes (Artemisia sp.) are two types of plants these birds are commonly associated with across their range.  In the Mojave, they also make use of abundant creosote bush scrub.

Birds of the Desert: Residents & Spring Migrants

Nearly everyone knows the desert as a barren, desolate land of extremes: high heat, low precipitation; little available food and water; prickly, spiny, unfriendly plants growing in a sea of rocks and sand as far as the eye can see.  But for those who stop and look closer, the desert reveals itself as the beautiful, incredible, mesmerizing place it truly is, teeming with unexpected life. Juvenile male Costa's Hummingbird visiting chuparosa blooms next to our campsite in Anza-Borrego Desert State Park. I particularly love the desert in the spring, when the annual wildflowers, cacti, flowering trees and shrubs are all in bloom.  (I've experienced the desert in the searing 120 degree heat of summer, and the rainy, even snowy cold of winter... and spring wins every time!)  Eric and I just returned from a week in the Colorado desert, exploring the imperiled, accidental Salton Sea (more on that coming soon), the vital wetlands of the Sonny Bono Salton Sea National Wildlife Refu

A Shorebird Primer: Godwits, Curlews, Willets and Whimbrels

Image
For those of us living in the Great Central Valley, autumn is the time to head to the coast.  Of course, there is no bad time to visit California's magnificent coastline.  But as the heat and haze of summer drag on in the Valley, the sea becomes increasingly tantalizing: September and the onset of autumn bring sunny weather and an abundance of migratory seabirds and shorebirds to our coast. A new birder visiting California's Central Coast will undoubtedly be met with a splendid array of very confusing birds.  Among these are small shorebirds like  "peeps" (sandpipers), Sanderlings and various  plovers .  But the larger birds can be just as confusing, until you learn a few distinguishing features.  Four large shorebirds that are commonly seen (and commonly confused) along California's Central Coast are Godwits, Curlews, Willets and Whimbrels.

Birding in Adverse Weather Conditions: Wind and Rain

Image
Though I often extol the virtues and merits of winter in the Central Valley , especially when it comes to birding, the whole truth is that we experience "bad" weather also, just like anywhere else.  But even when the winter weather rolls in, the birds are still out there!  And sometimes, despite our best planning efforts, a birding day happens to coincide with crummy weather.   In that case, what's a birder to do?  Usually, we go birding anyway!   Birders far more intrepid than I regularly brave the ice and snow of northern winters to see their favorite birds, so perhaps you should look to them for real tips on winter birding!  For those of us in the valleys of California, the worst weather we see - wind and rain - is really comparatively mild.  Birding on an extremely windy day! I don't know of anyone who actually likes birding in the rain.  But I would argue that birding in the wind is just as aggravating as trying to bird in the rain!   Wind can be utterly infuri

Joshua Tree Woodlands: A Tale of Sloths, Moths and the Trees that Need Them

Image
In 1844, early California explorer John C. Fremont gave a somewhat scathing review of Joshua trees when he wrote, "...their stiff and ungraceful form makes them to the traveler the most repulsive tree in the vegetable kingdom."  Rather unkind, don't you think?  But when Joshua trees were formally described by scientist William Trelease in the 1890's, he noted that Joshua Trees are "the most attractive of all the Yuccas."  I am inclined to agree with this sentiment, and must disagree most heartily with Lieutenant Fremont! I, for one, adore Joshua Trees, with their whimsical shapes and great ecological significance!  If you struggle with plant identification, the iconic Joshua tree, hallmark of the Mojave Desert, is a good place to start.  With densely spiked tufts protruding from the ends of gangly arms stretched towards the heavens, this looks like a plant straight from a Dr. Seuss book.  Native people called these trees “humwichawa,” and used thei

Winter Gulls: The Great I.D. Challenge

Image
Gulls are a fun challenge for birders, from beginners to experts.  A few things make gulls an interesting study: they are large and conspicuous in their open habitats, so they are easy to see, easy to put a scope on, and easy to watch and study for long periods of time.  Furthermore, gulls are almost always identifiable as gulls; none of this confusing warbler/vireo/kinglet nonsense! And yet, gulls are almost impossibly difficult!  (Though perhaps not nearly as difficult as Empidonax flycatchers!) An intimidating scene to many a birder: a mixed flock of gulls.  I see five different species of gull here. Oh, and one American Coot in the background. One of the reasons they are so complicated is most gull species take two or three years to achieve adult plumage, and go through multiple molts in a year.  So, you may be looking at three or four gulls together that look like four completely different species, when they are actually just different ages (individuals in their first, s

Exploring New Places: South Carolina's Salt Marshes and Tidal Creeks

Image
Throughout South Carolina's Low Country, winding tendrils of water wend their way through a sea of grass, rising and falling with each new tide.  Low-lying intertidal areas immediately inland from the coast, salt marshes and tidal creeks form the interface between upland forests and urban areas, and brackish estuaries where freshwater and saltwater mix.   Tidal creeks are, to a first-time visitor to the South Carolina coast like myself, absolutely beautiful, mysterious, enthralling places where silvery ribbons of water meander seemingly aimlessly through a vivid green matrix.  They give the impression that there is water everywhere , a foreign concept to someone from arid, drought-stricken Mediterranean California.  And that was my first impression of South Carolina: there was water everywhere I looked!  Water in the ocean, lakes, rivers, creeks and wetlands, water covering the ground, falling from the sky, in the air itself!   Is there any land at all in this veritable wa
