Which of the following characteristics would most likely enhance a tree's attractiveness to birds?

• A. Colorful bark
• B. Dense foliage
• C. Flowers
• D. Wide canopy

Answer: (C)

Flowers serve as a significant attractant for birds primarily because they provide a source of nectar, which is a food resource that many bird species, particularly hummingbirds, seek out. Additionally, flowers can lead to the development of fruits or seeds after pollination, further enriching the tree’s appeal to birds looking for food. In the context of tree attractiveness to birds, colorful bark, dense foliage, and a wide canopy may contribute to a tree's overall ecosystem value or shelter but do not directly provide the enticing food options that flowers do. Colorful bark may catch the eye of a human observer but does not serve a practical purpose for birds. Dense foliage may provide nesting sites or cover but does not directly enhance the food supply for birds. A wide canopy can create habitat space but, again, does not offer the immediate food sources that flowering trees do. Therefore, flowers are the most effective characteristic for enhancing a tree's attractiveness to birds.
