A heronry, sometimes called a heron rookery, is a breeding ground for herons.
Although throughout their breeding territories often on more protected small islands in lakes or retention ponds, herons breed in heronies (or also called rookeries, especially since other birds join them like spoonbills, storks, and cormorants), some of the notable heronries are:
Kaggaladu Heronry is in Karnataka state of India. This heronry, in the Tumkur district of Karnataka, was first made known to the outside world in 1999 by members of the Tumkur-based NGO Wildlife Aware Nature Club.
Cleeve Heronry (grid reference ST463662), in a woodland near the village of Cleeve in North Somerset, UK.
Hilgay Heronry (grid reference TL635992) is in Norfolk. It is situated in a small copse on the edge of The Fens in the UK. An average of c. 40 pairs of grey heron nests each year at this site, in ash (Fraxinus excelsior) and European larch (Larix decidua) trees.
The Florida Everglades in south Florida, of the United States. Thousands of birds, including herons, egrets, spoonbills, and storks, nest in mangroves (genus Rhizophora).
