The present article summarizes a statistical psychiatry of the biodiversity of zooplankton population and their seasonal fluctuation in the Gangasagar pond, Jabalpur. The current analysis reflects the miscellany of zooplankton in correlation with the physico-chemical as well as the biological environment of the fishpond. Species diversity of zooplanktons was calculated as per the formula given by Shannon and Wiener (1949) & Odum (8). Perhaps the most important factor, which leads to aggregation of zooplankton, is the availability of natural food items as trapa harvests which serves as an organic wastes in the Gangasagar pond, Jabalpur.

Birds vary a great deal from one another in most of their life pattern like habitat, food, colorations, beaks, feet, size, plumage pattern, distribution and so on, likewise nests of birds are also having huge variations in their size, shape, structure, construction material used, construction pattern, selection of site for nest, nest architecture etc. Nest building in birds require extreme skills of engineering. In this regard birds have proved themselves expert engineers. Nest construction skills can be considered as a part of parental care or Instincts. Birds provide care to their young ones before birth by constructing nests. Here it should be mentioned that some birds are not building nests and some provide very less parental care to their young. Following could be the needs of nest construction: (1) providing site for egg laying and incubating (2) Shelter for the young and the parents (3) Protection against enemies (4) escape from predators (5) A means of Courtship e.g. the male weaver bird builds nest for getting mate. In this study nests of birds were studied which are found on Christ college campus (CCC), Rajkot. Christ College is situated beside Saurashtra University in the Munjaka village. The area is full of vegetation, and has two streams and a water body. There was a great degree of variation amongst their nests. Many birds had selected leafs and twigs of neem tree (Azadiracta Indica) for making their nest. A variety of materials like Leafs, Grasses, threads, plastic bags, plastic rope, hairs, cloths, twigs, Papers, Spider web, thin branches, feathers, cotton, roots, etc were used for nest creation. The bird and their Site for nests are given bellow:(1) Robin- in holes near Canteen Hill, (2) Red vented bulbul- bushes of Durantia Near biology laboratory, (3) common Myna-window of Biotechnology laboratory, (4) Common Tailorbird-on Tecoma plants and Phalsa (Grewia subinequailis) plant near chemistry laboratory, (5) Indian Silver bill-Top of Zizyphus mauritiana plant, (6) Shikra- on a neem tree (Azadiracta indica) near water body in the botanical garden, (7) Grater coucal- on a Neem tree (Azadiracta indica) and Bamboo (Dendrocalamus strictus) in Botanical garden (8) Plain prinia-In Pendula pendula Near Canteen, (9) Eurasian Golden Oriole and (10) Black Drongo -Near Student parking in Gulmahor (Delonics regia), (11) Pond heron-on tree of Pardesi papal (Ficus benjamina) Opposite to reception, (12) Red-wattled lapwing-Down the hill near sports ground, (13) Rock pigeon- On Lintel near window 3^rd floor, (14) Baya weaver bird-A colony hanging over water on neem tree (Azadiracta indica) behind botanical garden and on Acacia nilotica plant, (15) Black winged kite-Prosopis cineraria (16) Dusky crag martin-On wall near reception Cart (17) Green bee-eater-Holes in hill near canteen, (18) house sparrow-In water outlet pipe.
