Collared forest-falcon (Micrastur semitorquatus) preying on a squirrel in a fragment of atlantic forest with a revision of the predation events for the species
We recorded predation on the squirrel Guerlinguetus ingrami by a Collared Forest-Falcon (Micrastur semitorquatus) through camera trapping in a forest fragment of Atlantic Forest in the interior of São Paulo state, Brazil. The squirrel was captured while it moved across the forest floor. A compilatio...
