Spearow
The Tiny Bird Pokémon
Type: Normal/Flying
Official Registration #: 21
Entry: Much like many other bird pokémon, spearow travel in large flocks which hunt and defend sizable amounts of territory in unison. Also like other birds, it is known for its ability to fly at high speeds, which allows it and the rest of its flock to descend on its prey in seconds. However, unlike many other birds, spearow possess small wings that it must flap at high speeds in order to stay airborne, a fact which renders it inept at flying at high altitudes or over long distances. Thus, spearow is a creature that finds itself inadequate at the one thing most other creatures like itself excel at to the point of making that thing be a major component of their existence … which is why this writer and his unfortunate lack of battling aptitude in a world that relies on battling feels a sense of empathy for the spearow.

Fearow
The Beak Pokémon
Type: Normal/Flying
Official Registration #: 22
Entry: The evolved form of spearow, by battle experience. Unlike their pre-evolved forms, fearow possess broad wings and an incredible amount of stamina, which enable them to fly for long distances without needing a break. They are also adept at hunting, including swooping onto prey and ascending back to an appropriate altitude for flight in a matter of seconds. All of these skills are fantastic for the fearow and considerably more inconvenient for prey, such as you, if you happen to be trapped in the form of a rattata. …You know. Just as an off-hand example.
