GO is definitely going to make Fletchling happen during March Community Day.
The Tiny Robin Pokémon will be out in droves on Saturday, March 6, 2021, from
11:00 a.m. to 5:00 p.m. local time. Look out for Fletchling
appearing more frequently in the wild—you might even encounter a Shiny one, if
you’re lucky! Plus, if you evolve a Fletchinder (the Evolution of Fletchling)
into Talonflame during the event—or up to two hours afterward—that Talonflame
will know Incinerate, an attack it can’t normally learn.
March Community Day will also feature additional bonuses.
Incense activated during the event will last for three hours, and you’ll earn
three times as much XP for catching Pokémon. Make sure to take a few snapshots
during your Community Day adventures, too—you just might discover a surprise.
A Fletchling Community Day-exclusive Special Research story,
The Bravest Bird, will be available through the in-game shop for US$1 (or the
equivalent pricing tier in your local currency). There will also be a
one-time-purchase Community Day Box available for 1,280 PokéCoins that contains
50 Ultra Balls, five Lucky Eggs, a Poffin, and an Elite Fast TM.
Have fun with Fletchling on Community Day, Trainers!
