Nesting behavior of painted-storks in Lucknow district of Uttar Pradesh, India
The Painted stork is a large wading bird in the family Ciconiidae and is listed as Near Threatened. A study was carried out in Lucknow District, Uttar Pradesh, India from July 2013-March 2014. Painted storks show only seasonal short distance movements in search of food and breeding grounds. They are the local migratory bird. Selection of the nest site is often considered as an important factor of reproductive success in many bird species. The aims of the study was to understand the factors affecting selection of nesting habitat and nest tree as well as time management during nest building so as to recommend management of the species for conservation. The role of nest site selection and nest building behavior has been poorly explored in this species. Painted stork prepares their nest in trees or areas that are near the water body. The nest trees selected were on Ashoka (Saraca longifolia). The main factor affecting the nest site selection was food availability. Both male and female participated in nest sanitation. The nest building materials consisted of fragments of old branches of trees, some soft green leaves (twigs of Eucalyptus) and grasses (Sacharum and Jussiaea). These branches helped in strengthening. The leaves and grasses helped in softening of the nest. The leaves of Eucalyptus have insect repellent properties.

A field study of the nest-building behaviour in the breeding season of the Asian Open-Billed Stork, Anastomus oscitans, was conducted in the Kulik Bird Sanctuary, Raiganj, Uttar Dinajpur, West Bengal, India. Observations were made throughout one complete breeding season (2007-2008) in the sanctuary. The open-billed stork comes in the last week of June at the Kulik bird sanctuary, stays there for 5 to 6 months and leaves the place in the month of December of every year. From the present observations it was noticed that about 58920 storks came to Kulik during 2008. Various types of behaviour were observed during this particular period. Coming to the Kulik, pairing of the individual storks start and mating display was observed within a day or two. Birds of a pair supplied the nest building materials to form the nest. To give a definite shape to the nest it took about 12-15 days before egg laying. The nesting territory consisted of a semicircle, some times circular and approximately wi...

Nesting Ecology of the Greater Adjutant Stork in Assam, India
Waterbirds, 2002
The nesting ecology of the Greater Adjutant Stork (Leptoptilos dubius), the rarest stork in the world, was studied in the Brahmaputra Valley, Assam, India during 1994-97. We made a study of nine colonies in the valley during the 1994-95 nesting season, followed by a more intensive study in two subsequent nesting seasons (1995-96 and 1996-97) of two colonies at Nagaon, in central Assam. We measured the dimensions of both nest and non-nest trees, nearest distance between nest trees, and nearest house, nearest forest, nearest road, nearest water source and nearest foraging ground from each colony. All of the colonies were near human settlements. The structure of nest trees differed significantly from non-nest trees in both the overall and the intensive studies. Number of nests was highly correlated with tree height, diameter at breast height (DBH) and canopy area. About 90% of nests were built on the top of the canopy. Storks preferred to nest in compact colonies on large, widely branched trees with thin foliage cover and nearby food sources.
Asian open bill stork is a colonial wetland local migratory bird having I.U.C.N Status of Least Concern belonging to family Ciconiidae. The name of this predominantly grayish white with glossy black wings and tail bird is derived from the distinctive gap formed between the lower and upper mandible of the beak in adult birds, which is used as nut cracker as an adaptation to handle hard and slippery shell of Pila (Apple Snail) which is its main food. The study was carried out in Nawabganj Bird Sanctuary, Unnao District, Uttar Pradesh, India from June 2013-December 2015. They show only seasonal short distance movements in search of food and breeding grounds. The purpose of the study was to understand the factors affecting habitat and nest tree as well as breeding behaviour so as to recommend management of the species for conservation. Open bills prepare their nest in trees or areas that are mainly inundated with water. The nest trees selected were on Jungle jalebi (Pithecellobium dulce), Babul (Acacia nilotica) and Arjuna (Terminalia arjuna). The main factor affecting the nest site selection was food availability. Both male and female participated in nesting, incubation and other parental duties. It has a long breeding season right from July to September. About 276 nests in 2013, 456 nests in 2014 and 102 nests in 2015 were recorded. In 2015 due to drought the open bill were not construct their nests in good number.
STUDY OF NESTING BEHAVIOUR OF PAINTED STORK

The village Rajpura (27⁰7'0"N 76⁰1'49"E) is located near Kota district, Rajasthan. It is about 26km. away from Kota. The study was carried out from July 2018 to December 2018. Painted storks were sighted first time in Rajpura pond doing nesting. During the study period 200 nests were observed in the pond trees. All the nests were built on Babul trees (Acacia nilotica) within the pond. The nest construction and egg laying was observed in the months of July 2018 and August 2018. Both males and females carried over incubation and other parental care. The main factor affecting nesting site selection were food and habitat availability. The nest built material consisted of old branches of trees and some soft green leaves. The observation suggested that Rajpura was one of the best nesting, feeding and breeding site for the Painted storks. So it is need to take immediate steps towards the conservation of such diversified pond.

At the Raiganj Wildlife Sanctuary the openbill stork Anastomus oscitans breeds together with five other Ciconiiformes forming one of the world's largest concentrations of this group in spite of increasing human interference. Human activity varied in different areas of the sanctuary due to different levels of protection. The openbill stork showed considerable tolerance towards man but direct human interference severely hampered its nesting success, particularly the fledgling rate. To avoid the danger of human interference the birds nested in large numbers in the undisturbed zone and also higher in the disturbed zone. The pressure of human interference thus forced the storks to change from their preferred nesting tree species and nesting height.

Daily survival rate of Painted Stork (Mycteria leucocephala) nests from four different nesting colonies in northern India (Delhi Zoo, Keoladeo National Park, Chhata and Khanpur) were modeled as a function of multiple covariates. These included nest and colony specific parameters, year, daily maximum and minimum temperatures and sizes of foraging wetlands in the vicinity. A total of 1,095 Painted Stork nests (606 from 2013-2014 and 489 nests from 2014-2015) were monitored at an interval of 4-7 days during a study spanning two breeding seasons. Considerable variations were observed in annual nest survival due to the amount of rainfall and hence availability of suitable wetlands for foraging in the vicinity of the colony. Nest survival was strongly dependent upon nest age in that nests built early in the season had a higher survival probability (β Nest age = 1.13, SE = 0.16). Daily survival rate was higher for nests located in high nest density colonies (β Nest density = 0.64, SE = 0.04). The additive effect of daily minimum temperature on the nest survival rate was positive (β Temp. min = 1.21, SE = 0.26) indicating that lower temperatures in winter negatively influenced daily survival rate. Nest survival in Painted Stork is significantly affected by environmental factors like rainfall and daily minimum temperature, besides colony specific parameters such as nest density.

The paper is an attempt to identify the causes and pattern of temporal variation of Asian Open Bill Stork (A. oscitans). To understand the status of environmental health of a habitat, the trend of arrival, food and habitat of bird population play innovative role and proper analysis of that has indicated that flood in the river Kulik very adjacent to Kulik Wildlife sanctuary is the foremost cause of temporal variation in the arrival of Asian Open Bill bird population. Apart from the flood, the changing climate, deforestation and anthropogenic factors are also responsible for decline in their arrival. Therefore, such analysis or approach of study does not only reveal the temporal qualitative change experienced by that habitat but also signify the impact of that on influx of bird population along with other species.

Storks are huge wading birds found throughout the Indian subcontinent. They are members of the order Ciconiiformes and have lengthy bills, necks, and legs. The Ciconiidae family is intimately related to wetlands, marshes, and swamps. The study was carried out for four years (January 2020 to December 2023) to determine the occurrence and distribution of stork species in India's drought-prone Kota region. The line transect and point count methods were used for road surveys and field visits. Despite its harsh climate, the Kota region is fortunate to host six species of storks (three resident and three winter migratory). The six species were sighted alone, in flocks, and in mixed flocks. They were seen foraging and resting in reservoirs, rivers, seasonal ponds, and agricultural fields with water. Seasonally, the type of bird flocks was changed. Sand mining in rivers, the disappearance of seasonal ponds, and severe changes in agricultural practices pose a serious threat to storks and other wetland birds. It is critical to include local communities in the conservation of the stork species.
