The common house sparrow, Passer domesticus is a small bird belonging to the family Passeridae. Here, we provide high-quality whole genome sequence data along with assembly for the house sparrow. The final genome assembly was made using Shovill/SPAdes/MASURCA/BUSCO which consisted of contigs spanning 268193 bases coalescing 922 MB. We employed rigo...

Dutta (2009) described a new subspecies roonwali of Sri Lanka Frogmouth Batrachostomus moniliger from Karnataka based on specimens in the collections of the Zoological Survey of India (ZSI). As this description has not found wide concurrence, we evaluated the specimens against the media available online as 800+ photographs as well as specimens in m...

Large carnivores play a crucial role in trophic cascades, affecting the population dynamics of both co-predators and prey within an ecosystem. Understanding the significance of these carnivores in trophic interactions is essential for developing effective conservation and management strategies. We examined the effects of occupancy dynamics and patt...

The red-breasted merganser Mergus serrator has a widespread global distribution with a stable population and is considered a winter vagrant in South Asia. Since 2016, this species has been recorded six times from many states in India, prompting us to analyse the specimens of the species deposited in the Zoological Survey of India's National Zoologi...

We examine the type localities of four taxa described in Blyth (1847, 1849 and 1852) that were originally reported as the ‘range beyond Simla, near the snow line’ or just ‘north-west Himalaya’ and suggest a restriction to ‘Tyne Range, interpreted as a range in Uttarkashi district, Uttarakhand, near Mussoorie’ based on an analysis of the data on lab...

Historically, White’s Thrush Zoothera aurea has been considered conspecific with the smaller Scaly Thrush Z. dauma (Ali & Ripley 1987), but it started getting recognised as an independent species from the 1990s, based mainly upon its vocal distinctiveness (Martens & Eck 1995; Rasmussen & Anderton 2012; Dickinson & Christidis 2014; del Hoyo et al. 2...

Globally,forest fire has been recognized as a major driver of forest degradation. Forest fires are considered to be a potential hazard with physical, biological, ecological and environmental consequences. In India, forest fires are the most significant, and a steadily increasing threat to ecosystem. Furthermore, fires are responsible for the loss o...

The Oriental Cuckoo Cuculus optatus has, till recently, often been considered conspecific with the smaller Himalayan Cuckoo C. saturatus, until Dickison & Remsen (2013), following Payne (2005), recognised it as a full species. This has now been followed by the IOC (Gill et al. 2022), and eBird/Clements (Clements et al. 2022); but not by HBW & BirdL...

While cataloguing the specimens held in the collection of the Zoological Survey of India (hereinafter, ZSI), Kolkata, we came across a few interesting specimens that we document here. Some of these were known to earlier workers, but remained untraceable, while others were known, but, as we found, had been misidentified. They include Black-browed Re...

The critically endangered White-bellied Heron (Ardea insignis) is a piscivorous visual forager that prefers to forage in fast-flowing freshwater rivers. This study highlights White-bellied Heron foraging behavior in the fast-flowing rivers of Namdapha Tiger Reserve during 2013–2017. The herons spent significantly more time and also made more foragi...

Two most recently described macaque species; the White Cheeked Macaque (Macaca leucogenys) and Arunachal Macaque (Macaca munzala) were discovered from a single biodiversity hotspot, the Eastern Himalaya. We conducted surveys in the West Siang, Arunachal Pradesh, India and collected five faeces and two skin samples of macaques that on DNA analysis i...

Of the 271 species of birds recorded previously from the East Kolkata Wetlands (EKW), only 162 species have been sighted continually during the last decade and 109 species become locally extinct, majority of which are water birds. Surveys were conducted in and around EKW to assess the impact of developmental activities on the avian diversity, espec...

The complete mitogenome sequence of the Great Frigatebird, Fregata minor was sequenced for the first time in this study. The mitogenome (16,899 bp) comprises of 13 protein-coding genes (PCGs), two ribosomal RNA (rRNA) genes, and 22 transfer RNA (tRNA) genes, and a control region (CR). The mitogenome was AT-rich (55.60%) with 11 overlapping and 18 i...

Habitat degradation and loss have affected many species across all major groups in India and elsewhere. However, the water birds are among the most impacted in terms of habitat loss and drastic decline in populations. The White-bellied heron (A. insignis) (WBH), a Critically Endangered and top conservation priority species, has lost much of its hab...
