Abstract: Ibisbill is a resident breeder in the Himalayas and winters in the lower Terai of Nepal. It has been nationally assessed as Endangered due to disturbance, hunting, habitat loss and climate change. We did a field survey in the East Rapti River from Late November 2022 to Mid-March 2023 to assess the population status, behaviour and threats in the Ibisbill wintering ground. Observations on the behaviour were made at three selected sites, each of 1.5 km transects. Household survey was conducted with 50 respondents using structured and semi-structured questionnaires to assess the prominent threats along with direct observations. A total of six Ibisbills were recorded during the study period in the wintering ground. Ibisbills fed on both terrestrial and aquatic invertebrates including stonefly, mayfly and caddisfly larvae. Feeding and Foraging accounted for 55% of the total activity time in winter followed by Resting (22%). During the survey, the bird was quite inactive and solitary as well as found to be good swimmers, preferring to cross rivers by swimming rather than flying. People in the vicinity of the East Rapti River reported that extraction of stones and boulders, pollution and disturbances by human activities were major threats to Ibisbill. We recommend further monitoring of the species and protection of the wintering grounds from excessive anthropogenic activities.

Abstract: The aim of the current survey was to detect the major causes of reproductive disorders in crossbred dairy cattle farms in Nyala City –South Darfur state. A structured questionnaire based on the survey objectives was used and SPSS software was utilized for the statistical analysis. The results of pertinent to the respondents indicated that the majority (69%) of herders ranging between age category (26 – 45) years, then those above sixty represented (15.4 %). Also, the results indicated that (73.1%) of respondents were married and the remaining (29.9%) were single. the major fertility defects identified in the study area were caused by environmental factors (53.8%), Both environmental and genetic factors (42.4%) and Physiological disorders represent (3.8%). In addition, absence of records (42.3%), failure of detecting heat sings (23.1%), absence of artificial insemination (AI) services (11.5%) and breeding bull (23.3%) all were also recorded as causes of infertility in crossbreed dairy cattle farms in the area of the study. The study confirmed that nutrition is the major recurrent cause of cattle reproductive disorders in this area, therefore, special attention should be directed through preparation of balanced rations for all nutrients, as well, other infertility causes should be seriously considered.
