Identification tips

1. Throat pouch color: Look for the male's throat pouch—Wreathed Hornbill has a black wreathed pattern, while Plain-pouched Hornbill is plain yellow. 2. Casque shape: Wreathed Hornbill has a more pronounced wreathed pattern on the casque. 3. Habitat overlap: Be aware of overlapping ranges in Southeast Asian forests. 4. Female identification: Females are more challenging to differentiate; rely on accompanying males for identification.

Both species are large hornbills with similar body sizes, making size an unreliable distinguishing feature.

Plumage

Male Wreathed Hornbills have a yellow throat pouch with a distinct black wreathed pattern on the casque, while male Plain-pouched Hornbills have a plain yellow throat pouch and a less pronounced casque. Female plumage is similar between the two species, with both having a darker head and neck.
