Chihuahuan vs Common Ravens: photo comparison

Image
Since we have been discussing how to differentiate Chihuahuan from Common Ravens on Cobirds (colorado birding listserve), I thought this was an opportune time to upload the two pics of Chihuahuan Ravens (below) I took on 12-19-2010 in Texas I hadn't got up here. Both sets of pics show very nicely the long and thick nasal bristles on the stout bill of Chihuahuans (more than 2/3 rd's of the bill) versus the long bill (with minimal nasal bristles) found on Commons. It may be useful to enlarge the pics of the Chihuahuan Ravens by double clicking on each one (won't work with Common Raven pics due to technical issues). SeEtta
