Population distribution and habitat analysis of Rufous treepie (Dendrocitta vagabunda) in Abbottabad, Pakistan

The Rufous treepie (Dendrocitta vagabunda) belongs to family corvidae, order Passeriformes which includes about 100 species. The current study was conducted to gather information about the Population distribution and habitat analysis of D. vagabunda at District Abbottabad, Pakistan. The data were collected on monthly basis both morning and evening times (2018-2019). “The ‘’Point count Method” was used for population estimation and ‘’Quadrates Method” for habitat analysis of study area. The result shows an average month-wise population density of D. vagabunda was maximum at Jhangra 0.14±0.039/ha, whereas minimum at Havelian 0.11±0.022/ha. There was no significant difference (p>0.05) among monthly population densities of D. vagabunda, however, a significant difference (p<0.05) was found between morning and evening times population of the specie. The present study revealed that importance value index (IVI) of plants species at Sherwan, Bakot, Havelian, Langra and Jhangra were 59.6±12.6, 50.1±6.9, 53.4±6.3, 66.8±10 and 60.1±7.7. Likewise, the frequency of shrubs at Sherwan, Bakot, Havelian, Langra and Jhangra were 33.3±4.2, 45±9.4, 46.7±8.2, 55.6±22.2 and 37.5±8.5. Similarly, the frequency of herbs at Sherwan, Bakot, Havelian, Langra and Jhangra were 40.4±6.0, 37.5±5.6, 53.3±7.4, 48.5±5.2 and 46.9±7.4 respectively. Our results show the study area as suitable habitat for D. vagabunda.

A baseline study on diversity of birds in Sani Bheri River Valley, Nepal

Rivers and lakes are important habitats for both resident and migratory wetland-dependent birds. This paper presents the study of birds’ seasonal diversity in Sani Bheri River Valley, outside the protected areas of Nepal. The study was carried out from 8-17 March 2019 (Spring) and 12-21 October (Autumn) 2019 covering a 52 km river stretch from Naighat (upstream area where Pelma River and Uttarganga River mix and flow as Sani Bheri river) to Remnaghat (downstream towards the confluence with Thuli Bheri) using the Mackinnon Listing method. The present study recorded 851 occurrences belonging to 11 Orders, 33 Families, and 71 bird species. Order Passeriformes (52 species) and family Muscicapidae (13 species) were dominant. Plumbeous Water-redstart (Phoenicurus fuliginosus) had the highest relative abundance (7.64%). Shannon-Weiner diversity index (H’= 3.61) and Evenness index (e= 0.85) indicate the diverse assemblage of avian fauna in the study area. This study showed that Sani Bheri River Valley provides the habitat for one globally threatened, four nationally threatened, and eight species listed in Appendix-II of CITES. The results provide the baseline information on avian species, which can provide a good database and can be incorporated in conservation implications.

Birds in Wetland Ecosystems of Ayodhya District, Uttar Pradesh

This study was carried out in the wetlands across Ayodhya District, Uttar Pradesh using fixed radius point counts, to understand the diversity and distribution of birds in these ecosystems. A total of 102 bird species belonging to 35 families and 12 orders were recorded from the study area. Amongst the order, Passeriformes (24 and 12) had the maximum number of species and families. The highest number of species recorded were Carnivores (44 species, 43%). A total of 61 bird species (60%) were resident, 41 bird species (40%) were winter visitors and ten species were in the threatened category of IUCN Red List (2021) which highlights the conservation value of wetland ecosystems in Ayodhya District, Uttar Pradesh.

Egg spottiness reflects female condition, physiological stress, and ornament expression in a common rallid species

Lay Summary • There is equivocal support for direct associations between maternal quality and deposition of protoporphyrin pigmentation (dark spots and blotches) in avian eggshells. • Research on protoporphyrin eggshell pigmentation has primarily focused on a single avian order (Passeriformes). • We examined associations of protoporphyrin-based eggshell pigmentation with female phenotypic and genetic traits in a non-passerine species, the Eurasian Coot. • Deposition of protoporphyrin in eggshells (total number per area of egg spots) positively correlated with female condition and expression of a putative bare-part ornament (frontal shield), while it was negatively associated with the level of physiological stress. • Protoporphyrin-based eggshell pigmentation acts as a reliable signal of female phenotypic (but not genetic) traits in the Eurasian Coot. • Signaling properties of protoporphyrin-based egg coloration are likely to largely differ between different evolutionary lineages of birds.

Diversitatea vegetala si animala a ecosistemului urban Orhei

Lately, the problem of biodiversity conservation is becoming more and more acute due to increase of anthropogenic impact. With the evolution of anthropogenic ecosystems, it also increases the vulnerability of species and biodiversity in general, as a result affecting ecological balance and environmental quality. The purpose of the researches was to evaluate the flora and fauna diversity in the Orhei urban ecosystem. The study was conducted during 2017 in 10 urban stations. Floral researches enumerate the presence of 146 species of magnoliophyte plants, grouped in 127 genera from 45 families. The most numerous were the species of the families: Asteraceae, Fabaceae, Rosaceae and Poaceae. The most frequents species are the eurybionte with wide ecological amplitude, some of which are included in the invasive species category. Vertebrates researches have revealed the fact, that the mammal fauna includes 29 species with a higher effective in the green areas of the urban ecosystem. The birds population of the ecosystem enumerate 58 species, prevail those from order Passeriformes.

Birds of Rawanwadi Region Bhandara, Central India

The region of Rawanwadi reservoir is a good habitat for insects, fishes, reptiles as well as birds. Its geographical location is 21.043197 N, 79.729924 E. Observations were done by two visits on every month from May 2015 to April 2016 in the morning and evening hours. Bird observation and recording were done with the help of binocular and digital cameras. Total 143 species of birds were recorded belonging to 15 orders and 41 families. Out of total 143 species 07 are migrant, 95 are Resident and 41 are Resident migrant. Seasonal variation is well marked in birds due to availability of food and nesting and suitable environmental conditions. Largest number (60) of bird species is recorded from order Passeriformes which belonging to 17 families.
