Influence of Prosopis juliflora on Breeding Success of Black- headed Ibis Threskiornis melanocephalus

The Black-headed Ibis (Threskiornis melanocephalus, Latham, 1790) is a large, white-water bird. Nehru Talai of Bhilwara district (Rajasthan, India) is an island-like structure with some exotic Prosopis juliflora (Vilayati babul) and native Vachellia nilotica (Babul), Ziziphus mauritiana, and Salvedora percica vegetations of which stands on the central island and provides an excellent nesting site of Black-headed Ibis. Bird census technique like the focal method was used to monitor Black-headed Ibis. Various nest parameters were examined from June 2023 to November 2023 at Nehru Talai. Prosopis juliflora is one of the top hundred recognized invasive species worldwide. The percentage of dropped eggs and nestlings per nest was higher in Prosopis juliflora than in Vachellia nilotica due to the branching angle of Prosopis juliflora being higher than Vachellia nilotica. In this article, we observed the impact of Prosopis juliflora on the breeding success of Black-headed Ibis and to conserve the near threatened Black-headed Ibis, the regular removal of Prosopis juliflora from the breeding sites.
