Stork in the context of "Heron"

Birds of prey or predatory birds, also known as raptors, are hypercarnivorous bird species that actively hunt and feed on other vertebrates (mainly mammals, reptiles and smaller birds). In addition to speed and strength, these predators have keen eyesight for detecting prey from a distance or during flight, strong feet with sharp talons for grasping or killing prey, and powerful, curved beaks for tearing off flesh. Although predatory birds primarily hunt live prey, many species (such as fish eagles, vultures and condors) also scavenge and eat carrion.

Although the term "bird of prey" could theoretically be taken to include all birds that actively hunt and eat other animals, ornithologists typically use the narrower definition followed in this page, excluding many piscivorous predators such as storks, cranes, herons, gulls, skuas, penguins, and kingfishers, as well as many primarily insectivorous birds such as nightjars, frogmouths, and some passerines (e.g. shrikes); omnivorous passerine birds such as crows and ravens; and opportunistic predators from predominantly frugivorous or herbivorous ratites such as cassowaries and rheas. Some extinct predatory telluravian birds had talons similar to those of modern birds of prey, including mousebird relatives (Sandcoleidae), and Messelasturidae indicating possible common descent. Some Enantiornithes also had such talons, indicating possible convergent evolution, as enanthiornithines are not considered to be true modern birds.

Waders or shorebirds are birds of the order Charadriiformes commonly found wading along shorelines and mudflats in order to forage for food crawling or burrowing in the mud and sand, usually small arthropods such as aquatic insects or crustaceans. The term "wader" is used in Europe, while "shorebird" is used in North America, where "wader" may be used instead to refer to long-legged wading birds such as storks and herons.

There are about 255 species of wader, most of which live in wetland or coastal environments. Many species of Arctic and temperate regions are strongly migratory, but tropical birds are often resident, or move only in response to rainfall patterns. Some of the Arctic species, such as the sanderling and grey plover, are amongst the longest distance migrants, spending the non-breeding season in the Southern Hemisphere; the bar-tailed godwit holds the global record for the longest non-stop flight of any bird, some flying over 13,000 km from Alaska to New Zealand.

Wading birds, also known in North America as waders, are members of several families of long-legged birds found in semi-aquatic ecosystems. Wading birds are not a monophyletic group and different authors classify different families as wading birds. The classification always includes the families Phoenicopteridae (flamingos), Ciconiidae (storks), Threskiornithidae (ibises and spoonbills), Ardeidae (herons, egrets, and bitterns), and the extralimital families Scopidae (hamerkop) and Balaenicipitidae (shoebill) of Africa. These were once classified together in the order Ciconiiformes based on overall similarity in anatomy and ecology, as well as some molecular data. However recent genomic studies have found that this group to be polyphyletic, with flamingos being more closely related to grebes while ibises, herons, the hamerkop and the shoebill are more closely related to pelicans. As a result of these changes flamingos are placed in their own order Phoenicopteriformes and Ciconiiformes are solely restricted to the storks. The rest of the waders have been reclassified into the order Pelecaniformes.

Other families that may be classified as wading birds include Gruidae (cranes) and Aramidae (limpkin). Unlike the previously mentioned families, cranes and the limpkin were never thought to be closely related to the heron-like birds and have always been classified as members of the order Gruiformes. Sunbitterns, the only member of the family Eurypygidae in the order Eurypygiformes, may also be considered to be a wading bird. In addition, the Anhimidae (screamers) of the order Anseriformes may be classified as wading birds. They are commonly found wading in open marshes and weedy lakes.

Lake Ichkeul (Arabic: بحيرة اشكل, romanized: Buḥayra ʾIshkul) is a lake in northern Tunisia, located 20 kilometres (12 miles) to Bizerte, the northernmost city in Africa on the Mediterranean Sea. The lake and wetlands of Ichkeul National Park are an important stopping-over point for hundreds of thousands of migrating birds each year. Among the lake's visitors are ducks, geese, storks, and pink flamingoes. Dam construction on the lake's feeder rivers has produced major changes to the ecological balance of the lake and wetlands.

A Martenitsa (Bulgarian: мартеница, pronounced [ˈmartɛnit͡sa]; Macedonian: мартинка, romanized: martinka; Greek: μάρτης, romanized: mártis [ˈmaɾ.tis]; Romanian: mărțișor [mər.t͡siˈʃor] ; Albanian: verore; Turkish: marteniçka [marteˈnit͡ʃka]) is a small piece of adornment, made of white and red yarn and usually in the form of two dolls, a white male and a red female. Martenitsi are worn from Baba Marta Day (March 1) until the wearer first sees a stork, swallow, or blossoming tree (or until the end of March (April 1)). The name of the holiday means "Grandma March" in Bulgarian and Macedonian, the holiday and the wearing of Martenitsi are a Bulgarian and Macedonian tradition related to welcoming the spring, which according to Bulgarian and Macedonian folklore begins in March.

In Albania, it is worn on the March 14 (the old first day of March in the Julian calendar) to celebrate the Summer Fest (Dita e Verës). In Albania, the Summer Fest is dedicated to the ancient Goddess Diana.

The marabou stork (Leptoptilos crumenifer) is a large wading bird in the stork family Ciconiidae native to sub-Saharan Africa. It breeds in both wet and arid habitats, often near human habitation, especially landfill sites. It is sometimes called the "undertaker bird" due to its shape from behind: cloak-like wings and back, skinny white legs, and sometimes a large white mass of "hair". It has often been credited with the largest wingspan of any land bird, with an average of 2.6 metres (8.5 ft) and some recorded examples of up to 3.2 metres (10 ft).
