Ludwig, J. P. 1964 and more melodious with tail cocked very high. Here I believe it to be a soliciting posture for the bird being "proposed" to often shows great interest (3 occasions). Once I watched a bird proposing to another - the second bird moved next to the proposing bird; then a third bird landed on the roost driving both birds away. Nest Building: Birds were seen to gather twigs and dried weed stems from other trees, other nests, and once from the ground. One bird was seen to bring a stick across the channel from Moku Manu to the Mokapu Point. Birds actively rob untended or deserted nests of materials and often individuals move from club roost to club roost robbing several different nests. When pairs of birds have eggs, a gathering bird brings a twig to the sitting bird who takes it with much vocalizing of the same reedy voice as in the other displays. A bird coming to the nest with a twig often announces his arrival 50-100' before arriving (3-5 seconds before alighting) with a continuous call. The arrival continues to call even after the twig is given to the sitter. In 49 minutes I watched a bird bring 4 sticks to the sitter - 3 were immediately put into the nest by the sitter, one was dropped, lodging some 18" below the nest. The arriving bird immediately retrieved it and presented it again to the sitter who then incorporated the twig successfully into the nest. In pairs with eggs the bringing of sticks to the completed nest may function to keep the pair bond strong and to insure the pre- sence of a high incubation drive in both birds. Several single birds were seen to carry the same stick to and from a nest sight a number of times. One bird flew about with the same stick 11 times in 46
