Is Pantanal yacare caiman mega-congregation happening right now?

As of today, in season, building toward peak (~July 20). Earth Exhibit tracks the live conditions and flags it the moment it is on.

As the Pantanal dries each year, water recedes into a shrinking network of rivers and ponds and yacare caimans (Caiman yacare) concentrate by the thousands on remaining pools and riverbanks.

These late-dry-season congregations are highly predictable in location and timing and draw large numbers of birds, capybaras, jaguars, and other predators to the same hotspots.
