It is a difficult thing to distinguish and requires long periods of observation.
Male and female crows look very much alike, although differ slightly in their behaviour. Males will get rowdyer in spring, during breeding season, and will often show off to the females by puffing up their feathers. They also fight other males and chase off rivals from their territory.
If the sex must be determined in a solitary crow which cannot be compared in behaviour to others of its kind, then a DNA test is the most effective (though rather expensive) way.
Also some females will lay eggs, even if not fertilised.

∙ 12y agoIf you are talking about American Robins, there is not much difference.. the male usually has a brighter reddish orange chest than the female. Individuals can vary in coloration so it may sometimes be hard to tell if you have a particularly bright female and dull male.
