| Roughly
one of every eight (13%) of all bird species is threatened with extinction mostly by habitat loss
(H), degradation, and fragmentation. After habitat loss, the intentional or accidental
introduction of nonnative species (I) such as bird–eating rats is the second greatest
danger, affecting about 28% of the world’s threatened birds.Population growth (P), also
threatens some bird species, as more people spread out over the landscape each year, increasing their
use of timber, food, and other resources, which results in destruction or disturbance of bird
habitats. Pollution (P), is another major threat to birds.A study done for the WWF found that
the effects of climate change (C), such as heat waves and flooding, are causing declines of
some bird populations in every part of the globe. Overexploitation (O) is also a major threat
to bird populations. Fifty–two of the world’s 388 parrot species are threatened, partly
because so many par– rots are captured (often illegally) for sale as pets. | |
