ٻگهه (Heron) ڊگهين پيرن وارا، ڊگهين ڳچي وارا، تازي پاڻيءَ جا ۽ ساحلي پکي آهن جيڪي آرڊيڊي خاندان ۾ آهن، جن ۾ 75 تسليم ٿيل جنسون آهن، جن مان ڪجهه کي هيرون جي بدران ايگريٽ يا بٽرن سڏيو ويندو آهي. بوٽورس جينس جي ميمبرن کي بيٽرن سڏيو ويندو آهي، ۽، مونوٽائپڪ جينس زيبرلس ۾ زگ زيگ هيرون، يا زگ زيگ بٽرن سان گڏ، آرڊيڊي اندر هڪ مونوفيليٽڪ گروپ ٺاهيندا آهن. ايگريٽ هيرون کان حياتياتي طور تي الڳ گروپ نه ٺاهيندا آهن، ۽ انهن کي مختلف طور تي نالو ڏنو ويندو آهي ڇاڪاڻ ته اهي بنيادي طور تي اڇا هوندا آهن يا نسل جي پلميج ۾ آرائشي پلم هوندا آهن. ارتقائي موافقت جي ڪري، هيرون جون چونچون ڊگهيون هونديون آهن.

Herons are long-legged, long-necked, freshwater and coastal birds in the family Ardeidae, with 75 recognised species, some of which are referred to as egrets or bitterns rather than herons. Members of the genus Botaurus are referred to as bitterns, and, together with the zigzag heron, or zigzag bittern, in the monotypic genus Zebrilus, form a monophyletic group within the Ardeidae. Egrets do not form a biologically distinct group from herons, and tend to be named differently because they are mainly white or have decorative plumes in breeding plumage. Herons, by evolutionary adaptation, have long beaks.

The classification of the individual heron/egret species is fraught with difficulty, and no clear consensus exists about the correct placement of many species into either of the two major genera, Ardea and Egretta. Similarly, the relationships of the genera in the family are not completely resolved. However, one species formerly considered to constitute a separate monotypic family, the Cochlearidae or the boat-billed heron, is now regarded as a member of the Ardeidae.

Although herons resemble birds in some other families, such as the storks, ibises, spoonbills, and cranes, they differ from these in flying with their necks retracted, not outstretched. They are also one of the bird groups that have powder down. Some members of this group nest colonially in trees, while others, notably the bitterns, use reed beds.
