Its habitats are principally Wetlands, River and Riverside
It lives in all types of wetlands with salty or fresh water in winter. In the breeding season it needs wetlands with nearby tree vegetation. Also in Reservoirs, lagoons, ditches and irrigation ponds, stream banks, coast line.
This pecies is present in the province all year round, both as a wintering one and in the breeding period. There are also specimens in migratory passage. Gregarious during the reproductive season and lonelier during the rest of the year. Nest in trees or groves of riparian vegetation. One laying of 2 to 5 eggs. The Grey Heron feeds on fish, micromammals, small reptiles, including snakes, amphibians and insects. It shows a very calm behaviour when foraging. This bird explores the water while being very still, waiting for a prey to appear. Once sighted, it shoots the bill as if it were a harpoon.
Grey Herons gather to nest in treetop sites called heronries, some of which have been occupied for many decades. These have been monitored in the UK since 1928 through the Heronries Census. Overall the UK's breeding population has increased, with numbers peaking in the early 2000, but with some more recent declines.
