Humblot's heron, also known as the Madagascar heron, is a species of heron. It is commonly found on the north and west coasts of Madagascar but it is also present in the Comoro Islands and Mayotte. Humblot's heron is considered an endangered species due to its declining population. The major threats the heron faces are poaching, habitat destruction, and the invasion of alien species such as the water hyacinth.
Region
Western Indian Ocean (Madagascar, Comoros, Mayotte)
Typical Environment
Primarily occupies coastal and lowland wetlands along Madagascar’s west and north coasts, with outlying occurrences on the Comoro Islands and Mayotte. It frequents mangroves, estuaries, tidal flats, coastal lagoons, and mouths of rivers. Inland, it uses lakes, slow rivers, and flooded rice fields when undisturbed. Roosting and nesting often occur in mangrove trees or tall waterside vegetation close to feeding areas.

Humblot's heron, also called the Madagascar heron, is a large, dark heron mostly confined to Madagascar with small populations on the Comoros and Mayotte. It is often mistaken for the Grey Heron, but is notably darker with a blackish crown and heavy, dark bill. Major threats include wetland drainage, mangrove loss, disturbance, poaching, and invasive plants like water hyacinth that choke feeding sites. Conservation efforts focus on protecting coastal wetlands and managing invasive species.
