Chapter 11: Sustaining Biodiversity
3. This article deals with a regional issue.
4. In Donana National Park in Spain, a bird species called black kites have been using bits of plastic bags to build their nests.They use the plastic bags almost as a warning sign to others, they are meant to show off their nests. Nests that used the plastic bags had fewer intruders than those without plastic bags. Researchers conducted an experiment to see how the birds would react with a choice of white, green, or transparent shopping bags. The results showed that out of the 33 pairs that picked up some of the bags, 29 of them chose only white shopping bags. The birds preferred something that was white and visible.
5. I think it is good that the birds are adapting to their environment, but I think it is unfortunate that they have to use our pollution and garbage. I think some people will use this as an excuse for littering. People will think that they are helping the birds by polluting. This just shows that birds have adapted to the littering and finding a way to use the garbage to their advantage.
6. overawed- to restrain or subdue by inspiring awe; intimidate.
I have seen plastic in nests like the osprey. I find it disturbing, but if they birds, but maybe the birds don't. Nice selection of articles and well presented.
