A variety of different foods offered in multiple feeders will attract a high number of birds of many species. This is because different birds favor different foods, and multiple feeders allow more birds to feed at the same time. However, if too many feeders are placed in one area, the number of species attracted will decrease.
Which of the following best helps to explain the result of placing too many bird feeders in one area?
A)Predators, such as cats, tend to wait near bird feeders in order to ambush the birds that come to feed.
B)Some birds prefer to feed on different foods at different times of the year, so feeders should be adjusted seasonally.
C)Regardless of the number of feeders in an area, squirrels are likely to be attracted to the food offered.
D)If only one type of seed is to be offered, black-oil sunflower seed is the most popular type of bird feed available.
E)The more feeders in an area, the more likely they are to be dominated by a flock of a single type of large bird.
