|Riverside Tyrant (Knipolegus orenocensis)
|Marchantaria Island, Manaus, Brazil
The Riverside Tyrant, as its name suggests, is found along the Orinoco and Amazon rivers and particularly in early-succession growth (such as these Cecropia trees) on river islands (such as Marchantaria)
|The male is a dull black all over with a steely blue bill. The female is a dull olive-grey.
It is very like the Amazonian Black-tyrant (Knipolegus poecilocercus) which is found in the same geographical areas but is smaller and is usually found low down in shady, damp woodland.
We heard the "mechanical snap" sound mentioned in the literature. It was quite noticeable and presumably much more so than the "soft snapping sound" reported for the Amazonian Black-tyrant.
