As I think about it, it appears that crows have advantages and disadvantages.  The female crows seem to have the most disadvantages because they ususally do not  inherit a territory, only the males do.  The female only gets to inherit a territory if the matriarch of the family dies. Since crows usually take three years to mature before they mate, it would seem that it is more difficult for them to find a mating partner than other birds.  Yet, because crows mate with cousins and/or siblings that would appear to make the mating possibilities easier.  I wonder if those crows that mate with siblings have shorter life spans and/or they more vulnerable to disease?
