In birds, a little work has been done, earlier on the impact of such aberrations on breeding success. Further genetic analysis is suggested for “DNA barcoding method” which can detect such genetic changes in Black-headed Ibis.

Biodiversity is divided into three levels-genetic, species, and community or ecosystem. It is highest in the tropical region (0°-20° Latitude) of the earth. Habitat destruction, habitat fragmentation, habitat degradation, invasion of exotic/alien species, pollination, overexploitation of natural resources, co-extinction, infectious disease, hunting & pouching, domestication, jhum cultivation, and many natural disasters are responsible for biodiversity loss. Biodiversity is conserved by In-situ/on-site (hot spots, wildlife sanctuaries, national parks, biosphere reserves, tiger reserves, eco-tourism sites, biodiversity heritage sites, Ramsar sites, and leopard reserves) and Ex-situ/off-site (zoo, botanical garden, cryo-preservation, gene bank, seed bank, semen bank, biological park, and deer/bird/peacock/cow/fish parks) conservational methods. Along with this, several projects like-Project Tiger, Gir-Lion Project and Crocodile Breeding Project etc. have also been run by the government to conserve the particular species. Living organisms are listed in different conservation categories (Not Evaluated, Data Deficient, Least Concern, Near Threatened, Vulnerable, Endangered, Critically Endangered, Extinct in the wild, and Extinct) that are made by IUCN. To prevent biodiversity loss, we all need to make efforts to conserve it.

Polygyny is defined as several females mating with several males. Lek-based mating is a form of polygyny where the male has no attachment to the females with mates, and similarly mating females lack attachment too.

We documented our observations using a Nikon P500 camera between 20 June 2023 and 27 July 2023. The nest was built on a pile of pebbles that the adults had accumulated.

The 102 species of birds from 39 families were identified. Most of the families were represented by less than 10 species except family Anatidae. These include 69 residential and 33 winter visitors species. The 42 species of water dependent birds was observed. Among these bird species, 35 were omnivorous, 34 carnivorous, 25 insectivorous, 05 granivorous, 02 frugivorous and 01 nectivorous respectively. For the conservation of avifauna, creation of buffer zone and strict implementation of regulation is needed.

During continuous study from four different seasons (2019-2022) at this site, we observed many individuals with red patches on their neck. The red-colored patterns are due to the deposition of pigment in skin of the neck. At present there is strong evidence as to its significance. We saw the significance of red neck patterns on pairing as well as breeding of BHI.

It is a large, white-water bird with a prominent bare black head and neck, and a long, down-curved black bill. The body of this species is elongated but robust. The tail of the black-headed ibis bears grey ornamental feathers. Both the male and female black-headed ibis are similar in size and appearance. We observed many leucistic Black-headed Ibis during breeding season. Almost partially leucistic individuals (15) were solitary and perched on nesting trees but few birds (only one) form pairs with normal individuals of Black-headed Ibis at the end of breeding season. The comparison of various behaviors like nest building, courtship and mating, incubation, hatching and feeding of such abnormal and normal mophs, were studied June 2019 to October 2020, factors affecting the breeding success of the species were also analyzed. The abnormal morphology failed to form a pair like normal morphs during breeding cycle.

This wetland is situated in a highly populated part of Bhilwara city. At 0800 hon 17 June 2020, AKS saw a Glossy Ibis Plegadis falcinellus onan Acacia nilotica tree; it was incubating an egg, and adding some material to its nest. He saw another nest of the Glossy Ibis on another Acacia, just 3 m away. Both nests were c.5 m above the ground. Other nesting birds of this heronry were the Black-headed Ibis, the Asian Openbill Anastomus oscitans, andthe Black-crowned Night Herons Nycticorax nycticorax. They had constructed 105, 46, and 87 nests respectively. Glossy Ibis nests were placed c.10 m away from the nests of other birds in the heronry. The diameter at the outer rim of the Glossy ibis’s nest was 28 cm, that of its cup was 08 cm, and its depth was 04 cm.
