Guyana is definitely one of the best - and one of the few - sites to see this spectacular and outlandish bird. Guianan Cock-of-the-Rocks are Guianan Shield endemics, found nowhere else in the world besides the Guianan Shield which includes Guyana, Surname and Venezuela. The bright orange male has an extraordinary half-moon crest, which is used is competitive displays in lek gatherings to attract a female. 

 

The smaller of the two cocks-of-the-rock, the male takes the lesser part in breeding, is polygamous, and has nothing to do with nesting once mating is done. The male's energy instead is devoted to very elaborate display rituals that show off its magnificent plumage. These displays take place in communal leks, where 40 or more males may gather to challenge rivals and beckon the females.

The displaying male shows its crest and plumage so much that the bill and tail become obscured, almost making it difficult to recognize as a bird. Within the lek, each bird has its own perch on a low branch, with a "court" on the ground below that is cleared of dead leaves by the draughts of each male taking off and landing. They also have a variety of calls and movements, showing off the crest and elongated filaments on the rump and secondaries, and snapping their bills. Males display on branches about 2.5 m (10 ft) from the ground until a female approaches, when the males display and call from individual plots on the ground. The female chooses a male by landing on the ground behind a male and pecking him on the rump, the male turns round, and mating takes place almost immediately.
