It”s not the stork pdf

Mycteria leucocephala – Pak Thale. It’s not the stork pdf previously included a number of other families, such as herons and ibises, but those families have been moved to other orders.

Storks are large to very large waterbirds. Their shape is superficially similar to the herons, with long legs and necks, but they are heavier-set. The shape of the bills is linked to the diet of the different species. These have evolved to hunt for fish in shallow water.

These bills have evolved to help openbills feed on their only prey item, aquatic snails. North America and large parts of Australia, The centres of stork diversity are in tropical Asia and sub-Saharan Africa, with eight and six breeding species respectively. They are fairly diverse in their habitat requirements. Species like the marabou and Abdim’s stork will frequently be found foraging in open grasslands of savannah. Preferred habitats include flooded grasslands, light woodland, marshes and paddyfields, wet meadows, river backwaters and ponds. Many species will select shallow pools, particularly when lakes or rivers are drying out, as they concentrate prey and make it harder for prey to escape. Less typical habitats include the dense temperate forests used by European black storks, or the rainforest habitat sought by Storm’s stork in South East Asia.

They generally avoid marine habitats, with the exception of the lesser adjutant, milky stork and wood stork, all of which forage in mangroves, lagoons and estuarine mudflats. A number of species have adapted to highly-modified human habitats, either for foraging or breeding. In the absence of persecution several species breed close to people, and species such as the marabou and white stork will feed at landfill sites. The storks vary in their tendency towards migration.

Temperate species like the white stork, black stork and Oriental stork undertake long annual migrations in the winter. The routes taken by these species have developed to avoid long distance travel across water, and from Europe this usually means flying across the Straits of Gibraltar or east across the Bosphorus and through Israel and the Sinai. Migrating black storks are split between those that make stopovers on the migration between Europe and their wintering grounds in Africa, and those that don’t. The Abdim’s stork is another migrant, albeit one that migrates within the tropics. It breeds in northern Africa, from Senegal to the Red Sea, during the wet season, and then migrates to Southern Africa.
