Figure 3: Seed dispersal process.

Red-spectacled amazons (Amazona pretrei) pick up seeds from Parana pines (a) and often disperse the seeds carrying them in the bill (b) to distant perches to be handled and consumed (c). In c, one amazon perched on a distant Eucaliptus tree and dropped the partially-eaten seed. Photographs taken by N.P. Prestes (A), J. Martinez (B), and J.L.Tella (C).
