Pestilence

 is a mission in Red Dead Redemption.

Story
Abigail asks John to stop the crows from eating all the corn from the ranch silo which they have broken into again.

Walkthrough
This mission requires the killing of many crows where the majority sit on the silo. To complete this mission, John Marston must scare the crows before most of the corn is eaten. The most useful weapon to complete this mission is the Evans Repeater holding a rather large bullet capacity of 22 shots. Using Dead eye targeting to shoot them, you must carefully pick the birds sitting on the silo before advancing to the ready flying birds and the lucky few who escaped. It is advised that you bring items that restore your Dead eye as you can easily lose it unless you have the max sharpshooting and hunting skill.

Tips & Tricks

 * This is an easy mission to earn the Sharpshooter Challenges Rank 9 achievement which requires the player to kill six wild animals without reloading their gun. While in Dead Eye Targeting Mode, target at least 6 crows before shooting.
 * Drink Moonshine right before aiming at all the birds, as this will increase the amount of time in which Dead Eye Targeting mode can be used.
 * Watch for the birds trying to fly straight into the silo opening, because this is when the meter will fall the fastest.
 * A trick to completing this mission quickly is to use a Mauser Pistol and hold the trigger to release quick bursts of fire that can eliminate the birds when they gather in a group.
 * A well aimed and cooked dynamite stick will complete the mission quickly, though it is very difficult to pull off.
