First nests of Madagascar pond-heron for 2019

In October 2019, GEPOMAY carried out their second ULM flight in the 2019-2020 season with the aim of identifying heronries and characterizing their movements. A second flight which made it possible to rule on an early reproduction of the Madagascar pond heron by observing several nesting pairs.

A first flight in August

For the 2019-2020 season, a first ULM flight was conducted on August 8 and confirmed the establishment of heronry at three breeding sites among the five known. At first sight, only western cattle egrets were installed.

This second flight confirms the beginning of the breeding season of the species in Mayotte. The species does appear to have started breeding in the mangroves of Chiconi-Mangajou and Ironi Bé but for the moment no individuals have been observed in the mangroves of Dzoumogné, Ambato and Malamani while the species nested there last year. Several causes are suspected on the absence of the species on these sites including the disturbance such as noises. The total population may also be concentrated only at two sites this year. A later installation on these sites during the season is not excluded either.

The actions of GEPOMAY
In order to know more, GEPOMAY will carry out regular monitoring of the heronries by drone and ULM, will carry out counting of the populations present in Chiconi and Ironi Bé to see the evolution of the breeding population and will contact the structures which are monitoring the others Islands of the Indian Ocean: Asity Madagascar, Mohéli on the assumption that some individuals of the species have left Mayotte to go nesting there.
