Waders belonging to order Charadriiformes are commonly found along shorelines and mudats that wade in order to forage for food (such as insects or crustaceans) in the mud or sand. Bogs, marshes, mudats, shorelines, ponds, and ooded areas are all popular habitats for wading birds. The waders include storks, spoonbills, cranes, herons, egrets and ibises. They have certain physical and behavioural adaptations for living on or near water. Wading birds depend on water as a source of food, shelter, and nesting sites. Wading birds wade into shallow water to obtain food, instead of swimming and diving in water in search of feed that is not found on land. If we study the morphology of wading birds, they have lots of characteristics and adaptations that are useful in a watery habitat. Long legs of the wading birds help them to keep their feathers high and dry when wading into water in search of food. A long neck and a long bill are adaptations that make it possible to strike at prey while walking around on long legs. The benets of wading bird′s long, thin, spread-out toes are three-fold: toes help them to keep their balance and also help them to walk in mud without sinking. While walking in water and mushy mud, thin toes are easier to lift and set down. Spread-out toes also prevent them from sinking into soft mud in the water and at the water's edge, and above all those toes also disperse the weight of these big, tall birds, helping them keep their balance over their long legs. Waders are ecologically dependent on wetlands, as they provide good habitat to them for feeding, roosting, breeding, nesting, pre-migratory requirements, migration and protection from predators. So, wet lands plays an important part in the life cycle of wading birds. Wetlands have got highest capacity and are often extremely rich in bird and animal life. The present study aims at the assessment of diversity and residential status of wading birds in Yamuna basin near Hodal in Palwal District. It is located at 27°53′39″N and 77°22′09″E having an average elevation of 190 meters. Many ornithologists pay lots of their attention on eld study of birds during the eighteenth, nineteenth and twentieth century and till today many more are involved in the study of avian diversity near rivers. Avian fauna of Kalesar forests in immediate vicinity of River Yamuna in Yamuna-nagar District has been analysed by Kalsi (1998). Kulkarni et al.(2011) reported 151 species of birds from river Godavari; Balapureet al. (2012) reported 63 avian species from river Narmada. Other workers like Bahuguna(2008), Taketal.(2010), Gupta & Kaushik (2011), Gupta et.al(2012), Anupma et al (2014), Ankita et al (2019) have studied wetlands birds in various regions along the banks of rivers.

The Pichavaram Mangrove Forest (PMF) is one of the important wetlands in southern India. The PMF is harboring numerous species of shorebirds seasonally. The current study assessed the population characteristics of small wading birds by using direct count method from 2015 to 2016. In total, 27 species of small wading birds were recorded, in which the Little stint showed highest density 177.24±20.515 (No./ha.) and the Bar-tailed godwit showed lowest density 0.13±0.099 (No./ha.). Indeed the Little stint was only species turned highest density across the three different seasons studied. However, the bar-tailed godwit not recorded during the pre-monsoon and post-monsoon seasons, the Dunlin, Grey plover and Great sand plover not sighted during the post-monsoon season. The density, diversity and species richness of small wading birds showed significant differences among the seasons (P<0.001). The study inferred that the population characteristics of small wading birds are declining when compared to the previous studies. However exhaustive studies are essential to explore the quality of the PMF which is need of the hour since it is supporting various species of shorebirds seasonally.

AbstractPositive ecological relationships, such as facilitation, are an important force in community organization. The effects of facilitative relationships can be strong enough to cause changes in the distributions of species and in many cases have evolved as a response to predation pressure, however, very little is known about this potential trend in vertebrate facilitative relationships. Predation is an important selective pressure that may strongly influence breeding site selection by nesting birds. The American Alligator (Alligator mississippiensis) facilitates a safer nesting location for wading birds (Ciconiiformes and Pelecaniformes) by deterring mammalian nest predators from breeding sites. However, alligators do not occur throughout the breeding range of most wading birds, and it is unclear whether alligator presence affects colony site selection. We predicted that nesting wading birds change colony site preferences when alligators are not present to serve as nest protectors. Within the northern fringe of alligator distribution we compared colony characteristics in locations where alligator presence was either likely or unlikely while controlling for availability of habitat. Wading birds preferred islands that were farther from the mainland and farther from landmasses > 5 ha when alligator presence was unlikely compared to when alligators were likely. These findings indicate that wading birds are seeking nesting locations that are less accessible to mammalian predators when alligators are not present, and that this requirement is relaxed when alligators are present. This study illustrates how a landscape-scale difference between realized and fundamental niche can result from a facilitative relationship in vertebrates.

Belize is home to over 605 bird species, many of them wading birds popular with bird watchers who enjoy their bright colors and charismatic behavior. Bird-watching is a major contributor to successful wildlife conservation and is important as native habitat loses ground to development. This 4-page fact sheet written by Venetia S. Briggs-Gonzalez, Jorge E. Ruano, Justin R. Dalaba and Frank J. Mazzotti and published by the UF/IFAS Department of Wildlife Ecology and Conservation presents photos and descriptions that will help identify some common and some rare wading birds.https://edis.ifas.ufl.edu/uw469 Trifold brochure: WEC425/UW470, 4/2020 https://edis.ifas.ufl.edu/uw470

Many long-legged wading birds such as little blue herons (Egretta caerulea), great blue herons (Ardea herodius), and great egrets (Ardea albus) nest together in large aggregations called breeding colonies. Although different species vary in their habitat preferences, wading birds have several common requirements for nesting. Colony sites must provide protection from predators, nesting materials, and nearby foraging areas (Hafner 2000). In the past, wading birds nested in natural wetland habitats that are becoming increasingly scarce as wetland habitats are continually altered or degraded to accommodate human needs. The future success of wading bird populations may be determined by how well they cope with manipulated foraging and nesting habitats. In this document, we make recommendations on the creation of nesting islands for long-legged wading birds.  This document is CIR1473, one of a series of the Wildlife Ecology and Conservation Department, UF/IFAS Extension.
