Birds of the National Park Hutovo Blato

B & H Croatian Post Mostar as Post Authorities of Bosnia Herzegovina issued the second series of birds devoted to the National Park Hutovo Blato on November 1, 2009. The issue comprised of 4 postage stamps featuring species of birds like: Black-crowned Night-Heron, Common Quail, Water rail, and  Common Cuckoo .

Hutovo Blato is on the list of BirdLife International's Important Bird Areas. It is the largest reserve of its kind in the region, in terms of both size and diversity. It is home to over 240 types of migratory birds and dozens that make their permanent home in the sub-Mediterranean wetlands surrounding Deransko Lake.
In the migration season, tens of thousands of birds fill the lake and its surroundings. Every winter over 200 species of birds find their shelter inside this untouched nature.
The Black-crowned Night-Heron is the most widespread heron in the world. It is most active at dusk and at night, feeding in the same areas that other heron species frequent during the day.

Their habitat is various wetland habitats, including salt, brackish, and freshwater marshes, swamps, streams, lakes, and agricultural fields. Their diet are aquatic invertebrates, fish, amphibians, lizards, snakes, rodents, eggs, and other foods.The Black-crowned Night-Heron may nest in the same tree with ibises or other herons.
The populations overall is  stable with status  as Least Concern in the IUCN List.  Because of wide distribution and feeding habits, the Black-crowned Night-Heron is an excellent indicator of ecosystem health.

The Common Quail or Coturnix coturnix, is a small bird in the pheasant family Phasianidae and  widespread  in parts of Europe.

The Common Quail is a terrestrial species, feeding on seeds and insects on the ground. It is notoriously difficult to see, keeping hidden in crops, and reluctant to fly, preferring to creep away instead.
The call is uttered mostly in the mornings, evenings and sometimes at night. It is a strongly migratory bird, unlike most game birds.They nest on the ground and are capable of short, rapid bursts of flight.

The Water Rail or Rallus aquaticus is a  skulking  bird of the rail family which breeds in well-vegetated wetlands across Europe, Asia and North Africa.

Northern and eastern populations are migratory, but this species is a permanent resident in the warmer parts of its breeding range.
The Water Rail walks with a high-stepping gait. It swims, when necessary, with the jerky motion typical of rails and it flies short distances low over the reeds with its long legs dangling.  Water Rails are capable of long sustained flights during their nocturnal migrations and are sometimes killed in collisions with lighthouses or wires.
The Water Rail's numbers are declining, but it has a large population of 100,000–1,000,000 adults and a huge breeding range estimated at 15,600,000 km2 ; it is therefore classed as Least Concern on the IUCN Red List.

The Common Cuckoo (formerly European Cuckoo) is a member of the cuckoo order of birds, the Cuculiformes. It is greyish with a slender body and long tail and can be mistaken for a falcon in flight, where the wing-beats are regular
The size of Common Cuckoo is around 30 cm centimeters  long from bill to tail (with a tail of average 14 centimeters  and a average wingspan of 58 centimeters . The legs are short.
