Behaviour
Victoria and Ricardo witnessed this display between two tiger-herons. They say both tiger-herons kept at several meters distance. Only on makes the whole display while the other (in the last photo) looks impassibly.

Rufescent Tiger-Heron - Yellow-billed Teal
Tigrisoma lineatum - Anas flavirostris

We normally watch the tiger-heron catch a fish or an eel, here the prey is yellow-billed teal duckling. The duckling belonged to a family in Canal Viamonte and this tiger-heron may be the one nesting a bit further on a tipu tree. The Saturday before the ducklings had been attacked by a Harris's Hawk and saved their skin. Their parents protected them but this Saturday this duckling was not that lucky. The video does not show the tragic end.
