When generalizing about all of the members of a species, you can use the definite article (the). As in:
“There are several ways to protect the peregrine falcon.”
And:
“The blue whale is the largest mammal in the world.”
Don’t use this article when talking about only some of the species. Instead, use the plural form:
“It is imperative that we protect peregrine falcons in the United States.”
And:
“Peregrine falcons that live in cities are experiencing habitat destruction.”
And:
“I saw plenty of blue whales from the deck of the boat”
