Many of the current studies teach us that these two tasks (face alignment and face detection) can be achieved by the deep learning approach. In this research paper, we study and implement a cascaded neural network framework using deep learning to develop the basic correlation among them so that their performance can be enhanced. Our framework particularly uses a streamed or cascaded structure that includes three storage of designing deep convolutional network with great attention and predicts face and landmarks in a nonsmooth to smooth manner. Including under the learning process we suggested a new online hard sample mining strategy without manual sample selection. These methods achieved more accuracy as compared to leading techniques available on making a lot of effort on Face Detection Dataset and Benchmark and WIDER, FACE Benchma...

The study revealed the presence of 260 avians, both resident and migratory categories. Ten threatened category species were found, Critically Endangered two species, Vulnerable two species, and Near Threatened six Species,, including Malabar Pied Hornbill reported recently after 1991. One species was found extending its distribution range. The avian species encountered were categorized by feeding habits, the number of birds were found highest as Omnivorous and most petite as Nectarivores. In Indravati Tiger Reserve, this study revealed the presence of 165 additional species, which were not mentioned previously. Interestingly, species such as Pink-headed Duck and Lesser Florican have past records but have not been recorded in recent years. Finding a juvenile of Black Baza suggests its ...

The Little Spiderhunter Arachnothera longirostra (Latham, 1790) is a nectarivore bird species found in the Western Ghats (Ali & Ripley 1989), Lamasinghi in Vishakhapatnam District of the Eastern Ghats (Raju & Selvin 1971; Ripley et al. 1986), parts of Odisha (Majumdar 1979), eastern Himalayan foothills, and hills of northeastern India (Grimmett et al. 2014).

The study was carried out from 2017 to 2019 and 32 plant species were identified, along with animal matter from collected scats samples (n = 163). The identified food samples were placed into six categories: (i) vegetation (leaves of trees, shrubs, herbs and bamboo), (ii) hard mast (tree fruits and seeds), (iii) berries and soft mast (shrub fruits and seeds), (iv) agriculture and horticulture crops, (v) animal matter (insects & livestock), and (vi) unidentified items (roots, barks, twigs, etc.). The food preference of U. thibetanus comprises berries and succulent vegetation during the pre-monsoon and monsoon seasons, whereas hard mast was mostly preferred in the post-monsoon and winter seasons. The present study showed that the diet of U. thibetanus depends on the availability and propensities of food items...

This study was conducted during Jan to March 2014; totally 09 selected wetlands were surveyed in Kawardha, Kabirdham District of Chhattisgarh. Species diversity and dominance of birds were calculated. Totally 64 birds belonging to 36 families were recorded, out of these 64 species 35 water birds and 29 terrestrial bird species. Maximum diversity of birds was recorded in Sutiyapath dam. Bird abundance and vegetation cover were recorded. The highest numbers of birds were recorded in Chhirbandha lake (21) followed by Sutiyapath dam (19), Sarodha dam (15) and Lalpur Nursery (13). Three near threatened species, namely Threatened Egyptian vulture, Indian Black Ibis and Oriental White Ibis were recorded. In most of the wetlands Ipomea carnea (15.28 %) was the dominant species. This pond has abundant maximum occasionally birds and maximum number of birds. Sutiyapath dam ha...

They are vital habitats for resident as well as migratory birds for foraging, roosting and breeding activities. Kopra wetland is an important and suitable bird habitat for both resident and migratory birds in Chhattisgarh. This wetland fulfills the need of water for the surrounding agricultural land and it also acts as a site for food as well as a roosting ground to many resident and migratory bird species. Every year a huge number of birds including Waterfowl, waders and Terrestrial Birds migrate to this wetland between the months of October to March. A study was carried out to estimate the avifaunal diversity during three consecutive winter seasons from 2016 to 2018 and estimated 133 avifauna species belonging to 18 orders and 47 families. Out of 133 avifauna 80 resident and 53 migratory species were recorded, including four Near Threatened species which are Painted Stork (Mycteria leucocephala), Black-headed Ibis (Threskiornis melanocephalus), Eurasian Curlew (Numenius arquata), Blacktailed Godwit (Limosa limosa) and one Vulnerable (VU) Woolly-necked Stork (Ciconia episcopus) and one Endangered (EN) Egyptian Vulture (Neophron percnopterus).
