It is a long hanging bag. The access is on top. It is made of vegetal fibers. The female alone builds the nest though the male is very near in vigilant attitude. It takes the female two weeks to finishe the nest.

They repeat the nesting site when it is successful. Too many years in a row a pair nested behind the Viamonte Cabin. Another recurrent site is at the antenna. In 2010 three nests very near one another. The left top arrow shows the nest under construction at the moment. Teh other two nests are inactive.

EThis nest was spotted very near the Cabin at Canal Viamonte. It hung over the canal from the tree branch of the embankment. The construction begins in October and when it was nearly ready a storm or wind broke the branch and fell (in one photo the nest and branch which held it). The female began a new nest which was ready by the first days of November 2008. En 2009 the used the same nesting site.
