Grey-cowled wood rail

The grey-cowled wood rail (Aramides cajaneus) is a species of bird in the family Rallidae, the rails. It lives primarily in the forests, mangroves, and swamps of Central and South America, usually from sea level up to 2,000 metres (6,600 ft). In some places, it is occasionally hunted and kept for food. Large for a wood rail, the bird has a grey head and neck, with olive-green to dark brown upperparts. The chest and flanks are a rufous colour, with the belly, rump, and tail being black. The legs are coral red, the bill is a bright greenish-yellow, and the eyes are red. The subspecies avicenniae can be differentiated by its smaller size and the lack of a brown patch on the back of the head. From March to August, nests can be found on flat branches and in thickets with three to seven eggs that are incubated by the monogamous pair. The chicks can move soon after hatching. This rail feeds on a wide range of foods, from molluscs to seeds. The species is not threatened. (Full article...)

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.

As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
