text: Since the introduction of European colonization, the population of crows is stable in North America.
text: In the western Palearctic, populations are generally stable or increasing, but there have been local declines, especially on farmland, which may be due to agricultural policies that encouraged farmers to remove hedgerows (which provide nesting places), and to drain damp grassland and increase the use of pesticides, both of which could have reduced the availability of invertebrate food.
