Among the Lessons of Rachel Carson's 'Silent Spring'
Like many others, we maintain a bird feeder
in our yard, keeping it stocked during the cold-weather months as well as in
the summer. The feeder draws a diverse clientele—a couple of cardinals, an
occasional blue jay, mourning doves, and black birds. But, by far the largest
group to show up is the house sparrows.
These birds, despite being small, are known
for their aggressive and, at times, ruthless behavior. These traits have aided
them in staking out territory. Further enhancing their cause is an ability to
utilize human dwellings and outbuildings for nesting purposes. They’re also
known to confiscate the bird houses people have put up, even killing the young
of other species that have already taken residence in those houses.
