This is the Rufescent Tiger Heron, one of the residents of Kabalebo.
The Rufescent Tiger Heron (Tigrisoma lineatum) is often seen close to the river, looking for insects, frogs, fish or small reptiles to devour. Quite often it is spotted alone during the day. Whenever it feels that it is spotted or noticed by onlookers, it will 'freeze' on the spot. He will take advantage of his patron that is used as the perfect camouflage.
Here are some pictures of the Rufescent Tiger Heron as an immature. This one was spotted near the lodge while it was looking for some lizards and frogs on the ground. As seen in the pictures, it noticed my presence and froze on the spot. If the 'freezing' method fails, the young Heron will fly into the closest tree of the dense vegetation.
Here are some pictures of an adult Rufescent Tiger Heron. This one was spotted in the Sandcreek, a while ago. As you can see, it can stretch its neck very far too.
