Humblot's heron (Ardea humbloti), 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.
Humblot's heron is part of the subfamily Ardeinae, which are known as "typical herons". It has been suggested that Humblot's heron may be a darker morph of the grey heron due to their many similar physical characteristics, but this claim has been successfully refuted. Humblot's heron was formally described by Henri Milne-Edwards and Alfred Grandidier in 1885.
Local Malagasy names for Humblot's heron include "Kisirano", "Langaro" and "Langaroko", however these names are also associated with different species of herons, such as the grey heron. The scientific name commemorates the French naturalist Leon Humblot.

Rare
Under 5% of wildlife watchers report a Humblot's Heron sighting in Antananarivo on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 67th most-seen of the 69 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Humblot's Heron in Antananarivo on a given day, so our monthly data shows no clear season.
Only Antananarivo, in our data
Antananarivo is the only city on Wallace's Line with enough records to rate Humblot's Heron sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Humblot's Heron is recorded against all the birds logged in Antananarivo (6 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
