Is Amazon River Dolphin Breeding Congregation happening right now?

As of today, peak season now, through ~June 30. Earth Exhibit tracks the live conditions and flags it the moment it is on.

As the Amazon's annual flood recedes into the dry, low-water season (roughly June to October), botos (Inia geoffrensis) become concentrated in shrinking river channels, lakes, and lagoons.

This is when the pink dolphins gather in their densest groups and are easiest to find, because falling water leaves them less room to disperse into the flooded forest.
