The baya weaver bird is one of the common weaver birds which occur across the Indian subcontinent. The nest of the weaver bird is distinctive for the delicate craftsmanship of constructing complex pendent nests. This paper describes a morphometric study of nest of bayaweaver birds hanging on natural and man-made habitats of shivamogga district. A total of 30 nests (20 complete and 10 incomplete) were collected for morphometric measurements. Ten parameters namely total length, Total width, Stalk length, Nest length, Entrance tube length, Stalk width, Entrance tube width, Egg chamber circumference, Entrance tube circumference, Threshold taken and weight were measured of both complete and incomplete nest. One-way analysis of variance (ANOVA) inferred that Total width (0.0026), Stalk length (0.0185) and Egg chamber circumference (0.00082) significantly in the complete and incomplete nests. But in the parameters like weight, total length, nest length, entrance tube length, stalk width, entrance tube width, entrance tube circumference, threshold is insignificantly in the complete and incomplete nests.
