“…Owners of performing monkeys usually capture monkeys from the forests and urban monkey habitats and train them for performance, and monkey trading is common among the monkey performers’ community [Akhtar, 2014; Feeroz et al, 2013]. Release of untrainable monkeys to the nearest monkey population by this community is also common [Akhtar, 2014]. That Sundarbans (Karamjal) is the major source of the performing monkeys [Engel et al, 2013; Feeroz et al, 2013] is consistent with our findings.…”

While studies of rhesus macaques (Macaca mulatta) in the eastern (e.g., China) and western (e.g., India) parts of their geographic range have revealed major genetic differences that warrant the recognition of two different subspecies, little is known about genetic characteristics of rhesus macaques in the transitional zone extending from eastern India and Bangladesh through the northern part of Indo-China, the probable original homeland of the species. We analyzed genetic variation of 762 base pairs of mitochondrial DNA from 86 fecal swab samples and 19 blood samples from 25 local populations of rhesus macaque in Bangladesh collected from January 2010 to August 2012. These sequences were compared with those of rhesus macaques from India, China, and Myanmar. Forty-six haplotypes defined by 200 (26%) polymorphic nucleotide sites were detected. Estimates of gene diversity, expected heterozygosity, and nucleotide diversity for the total population were 0.9599 ± 0.0097, 0.0193 ± 0.0582, and 0.0196 ± 0.0098, respectively. A mismatch distribution of paired nucleotide differences yielded a statistically significantly negative value of Tajima's D, reflecting a population that rapidly expanded after the terminal Pleistocene. Most haplotypes throughout regions of Bangladesh, including an isolated region in the southwestern area (Sundarbans), clustered with haplotypes assigned to the minor haplogroup Ind-2 from India reflecting an east to west dispersal of rhesus macaques to India. Haplotypes from the southeast region of Bangladesh formed a cluster with those from Myanmar, and represent the oldest rhesus macaque haplotypes of Bangladesh. These results are consistent with the hypothesis that rhesus macaques first entered Bangladesh from the southeast, probably from Indo-China, then dispersed westward throughout eastern and central India.

“…Most of the respondents suggested that singing in francolins is higher during morning and late in the afternoon which is similar to the work of [1]. Similar to [34] majority of respondents suggested that the breeding season of Harwood's Francolin is from August to December.…”

This study was conducted at Abohoye Dengera natural forest to investigate the status of Harwood's Francolin (Pternistis harwoodi) and threats affecting its population. Data were collected using line transect method and questionnaire survey. The main objective of the study was to investigating the status of Pternistis harwoodi and anthropogenic effects at Abohoye Dengera natural forest. A stratified random sampling method was used to assess the Pternistis harwoodi across the four dominant habitat types found in the study area: forest, woodland, scrubland, and farmland. Surveys were conducted during January 2018 and August 2018 which includes both the dry and wet seasons. Data collection was carried out during 6:00 to 10:00 AM, and 4:00 to 6:00 PM, when the activity of birds was more prominent. Line-transect methods were used to collect data on Pternistis harwoodi. The Harwood's Francolin species was estimated using direct (Line transect) and indirect ("calls" of the Harwood's Francolin n) methods. Field data were collected from a total of 8 line transects ranging from 0.5-1 km, each 150-300 m far apart. During the study period a total of 83 Pternistis harwoodi were observed. A total of 60 households are living in the surrounding area. Out of these 30(50%) of them were interviewed. Major threats reported in the study area included: wildfire, agriculture, hunting, free grazing, predation, and firewood/timber collection. Among all these threats, deforestation was found to be the major threat in the study area, followed by wildfire, free grazing, agriculture, hunting, firewood/timber collection, and predation. Pternistis harwoodi preferred forest habitat followed by farmland, scrubland and wood land. To overcome the above challenges, proper conservation measures have to be taken to solve the problems and prevent the bird from its vulnerable situation.

The study proposes to discuss about the seasonal water bird diversity, habitat preference, assemblages of water bird species and their conservation problems in different agroecosystems. Field visits was done once in a week during Jan. 2021-Jan. 2023. Freshwater and saline agroecosystems are the study areas used for the water bird survey. The water bird study was conducted by direct observation method, point count method and line transect method. Observations were made using binoculars (10 × 50 Nikon) and video camera (Nikon Coolpix p1000). Based on the pilot study in 2020, we decided to concentrate on 16 species of waterbirds coming in the 3 different orders i.e., Order Pelecaniformes, Ciconiiformes and Suliformes. Compared to the different study areas, a greater abundance of water birds was recorded in winter season, while a lesser abundance was observed in the monsoon season. The species richness was highest in saline agroecosystem and water bird congregation was more in freshwater agroecosystem. Saline agroecosystem was the most preferred habitat used for water bird species. Agroecosystems support the globally threatened water bird species such as spot billed pelican, darter, black headed ibis and painted stork. Many factors that are listed below threatens the agroecosystems and it causes the decreasing assemblages of water bird species. They are high water intake due to heavy rain, electric lines, high growth of water hyacinth, fishing nets, solid wastes and garbage deposited from toddy shops, pesticides used in fresh water rice farming, tourism, crackers, high level of fishing activities, habitat destruction, communication towers, predators and white flags were introduced by farmers.
