I occasionally see the common raven
flying over my yard. In Southern California the ravens are hill birds,
they like to soar on the up drafts. When flying from one hilly area to
another, ravens alternate flapping and gliding. Crows
seldom soar and
glide only when landing.
When vocalizing, the feathers on the
throat of the raven fluff out more than on a crow. Notice that the
raven is all black, every part, just like the crow.
Since this raven was nice enough to
perch on a street light for his picture, I have included a picture of a
crow on a similar perch. They are sized
to the same scale for
easy comparison. Notice the beak of the raven is proportionately larger
than the crow's. The raven's tail is more rounded, though this raven
has molted some of its tail feathers.
