@LeMandaiEnthusiast‧
Thanks, actually I didn't notice this species during the visit too.
I recently noticed when looking back at the photos.
The cassowary is quite difficult to see in Melaka due to its enclosure design, with the large size and the only shelters are are the far end of the place.
@Toki I'm not sure which one this is and it's a shame that the photo didn't capture a frontal view of the wattle so that we could tell whether it was single or double. It looks strange for a Southern (Double-wattled) Cassowary; however, it also isn't a great match for the photos that I've seen for Northern Cassowary. The Northern Cassowary usually has a lot of yellow or red bare skin on the neck below the blue throat, so your photo matches Northern Cassowary in that respect. But the casque on the head looks more like a Southern to me because it tends to protrude straight up, while the casque of a Northern Cassowary tends to protrude forward with a flattened back surface. It's a strange looking individual either way - neck like a Northern Cassowary and casque like a Southern. If you can get a photo of the wattle, we might be able to settle the identification.
@Toki I have no idea if the two species can hybridize or not. They belong to the same genus, so they may be closely enough related to hybridize. I noticed after I made my post that LeMandiEnthusiast said that it looked like a Red-necked Northern Cassowary and he certainly has more experience with this group of birds than I have. I'm inclined to go with his identification until someone can provide evidence to the contrary. I've never seen a Northern Cassowary in-person and it seems like Malaysia would be one of the most likely countries to have this species in a zoo.
