Grey Herons are solitary birds outside of the breeding season. However, they often gather in large numbers at feeding sites and during migration. They are skilled hunters, patiently waiting for prey to come within striking distance or stalking it through shallow water. Their long necks allow them to reach into deep water or snatch prey from the ground with surprising speed.

During the breeding season, Grey Herons become more territorial and vocal. They perform elaborate courtship displays, including bowing, strutting, and bill-clapping. Both parents share the responsibility of nest building, incubation, and feeding the chicks.

Grey Herons are generally silent outside of the breeding season. However, during the breeding season, they produce a variety of vocalizations, including loud croaks, harsh screeches, and guttural rasps. These sounds are used to communicate with mates, defend territories, and warn off intruders.

• Global Status: Listed as Least Concern by the IUCN.
• Threats:
  • Habitat loss due to urbanization and agriculture.
  • Pollution of water bodies.
• Conservation Efforts:
  • Wetland restoration projects.
  • Protection of breeding sites.
