Final answer:
The statement that Canada Goose "chinstraps" and Common Loon "necklaces" are examples of background matching is false, as these features serve other purposes such as species identification and sexual selection.
Step-by-step explanation:
Canada Goose "chinstraps" and Common Loon "necklaces" are examples of background matching. The statement is false. Background matching refers to the idea that an animal's coloration matches the environment to camouflage itself from predators or prey. In the case of Canada Goose and Common Loon, the chinstraps and necklaces are not primarily used for background matching, but rather are distinct markings that can help with species or individual identification, and in some cases, sexual selection. Comparing this to the example provided, while both a penguin and a seagull have wings, they use them for different purposes. Similarly, the physical features of the goose and loon serve purposes other than background matching.
