| | AN EXPERIMENTAL STUDY OF THE MECHANISMS OF NEST BUILDING IN A WEAVERBIRD (Site not responding. Last check: 2007-11-06) |
 | | There are five stages to the building of the outer shell of the nest by the male (Figures 6 and 7): (1) initial attachment, (2) roof and egg or brood chamber, (3) antechamber, (4) entrance, and (5) entrance tube. |
 | | The male invariably builds the egg or brood chamber out in front of himself from the ring, while he leans over backward to build the antechamber and entrance on the opposite side of the ring, all the while keeping his feet on the threshold of the nest (Figure 6). |
 | | Thus, if the egg chamber is removed from a fresh nest, the bird does not ignore the defect, as if he had exhausted all of his building potential for that particular stage, nor does he continue merely building at the entrance side. |
