This sounds like the bowerbirds of Australia and New Guinea. The males of these species construct elaborate structures out of sticks and graas and then decorate them with objects found in the forest. Different species will tend to collect objects of the same color and shininess. For instance, the male stain bowerbird, who is a deep blue during the brreding season, will collect mostly blue objects to decorate his bower. The bowers themselves appear to act as the centerpeices of the males breeding territory. Most of the calling and other displays that are used to attract females take place around the bower. A search on the web found the following website with more information on bowerbirds: http://www.pbs.org/wnet/nature/bowerbird/ From here there are a number of links to other sites with even more information about and pictures of bowerbirds. Interestingly, the other birds you mention in your question are probably the birds of paradise, which are found mostly in New Guinea. The bowerbirds and birds of paradise are considered to be fairly closely related, being grouped in the same family (Paradisaeidae). You should be able to find information about the birds of paradise from some of the same sources of information about bowerbirds.
