Cities often offer wildlife a perk or two

According to the New York Times, birds in North America are in decline. Numbers are down by almost 30% since 1970. This is not something one would think based on the number and variety of birds sighted in London, Ontario.

And North American is not alone. In Europe, as well, common bird species are in decline. And what is driving this decline? Habitat destruction takes a big toll. Pesticides and chemicals in general are big culprits. And, of course, there is urban sprawl. Dr. Young, of the University of California, says humans are overusing the world. 

And yet humans do offer wildlife, such as birds, some appreciated perks. Bird feeders, bird houses and bird baths are all very popular with the feathered wildlife found in cities.
