Message: <blockquote data-quote="r f maginnis" data-source="post: 801598" data-attributes="member: 51934"><p>What is this, please?  I photographed this black-headed blue crow? about noon on 2/2/07 at Topanga (Trippett Ranch) State Park, California near an oak woodland and an open field perched on a fence rail and again foraging by digging in dried mud at the rim of an adjacent  small pond (see the dust on its beak). In Manual of Birds, Sibley paints a Tamulaipas Crow which he describes as all blue and limited in the US to Brownsville (near the mouth of the Rio Grande)  Topanga is in the coastal mountains about 5 miles from the sea and Malibu.  The altitude would be at most 2000 feet.  For comparison, the fence post is 4x4 inches or 5.6 on the diagonal. Note the pale legs and soft feathers on the back.  Topanga is a place where crows and ravens tolerate one another.  This is a digital photo unretouched.  Thanks.</p></blockquote><p></p>
