Trivia

 * Initially, the Alolan Vulpix task was "Hatch 7 Eggs". A bug disabled shiny Alolan Vulpix to be encountered in Research task. Niantic later removed this Research.
 * After the bug was fixed, the task was changed to hatch 5 eggs only and released again. It was changed to hatch 4 eggs only 2 days later.
 * Due to coronavirus outbreak, select Field Research tasks that could be difficult to finish from home are removed since March . A list can be found here.
 * The task "Win 1 Great League Trainer Battles against another Trainer" in April is written wrong, the correct requirement should be "Win in the GO Battle League". This was later fixed.
