If you’re on the trail, on the street, or having a fun day exploring in the outdoors you will likely encounter crows and ravens.
Crows and ravens are thought of as the same kind of bird, but these are actually two different species. There are many ways to identify the two, but here are some basic features I look for:
(The above photo is of a raven. This beautiful bird soared overhead, low enough for a great photo while on a day hike in northern California.)
If you see a monster-sized crow it is most likely a raven. Ravens can be up to 24+ inches in length, while crows are smaller at 18 inches.
Ravens are shy and often solitary while spending a lot of time on the ground. Crows tend to be noisy, bold and sometimes congregate in large numbers.
Ravens soar more than crows; conversely, crows tend to flap their wings more.
Ravens give a very low “croonk” sound, but can give a variety of calls; crows give a loud “caw.”
Ravens have black and very heavy/thick-looking beaks that can be 3 1/4 inches or more in length. The beak of a crow is less thick and shorter at about 2 2/3 inches.
The tails of ravens in flight are wedge-shaped (think diamond shaped). The tails of crows are more fanned (the shape of a hand fan).
