Bird watchers find in Madagascar an exceptional quality of observations : although the 284 birds, might seem a small number, one counts 36 endemic kinds, 4 whole endemic families, and taking into account the surface of Madagascar, appearing in fourth position in the world, only 3 species of introduced birds could establish a perennial population.
Some birds in Madagascar are specific in their primitive behavior, others still make their nests on the ground, or even under the ground. The Malagasy species of the largest to the smallest, within each family, filled in the ecological niches held by other species on the other continents.
On the 81 migrating species, 9 of them nest in Madagascar. On the 209 nesting species, 109 are endemic of Madagascar (52%), Only 9 % of the forest species can live in open space. That explains the fragility of birdlife in Madagascar, as it is closely related to the preservation of forests and 97 % these forest species are endemic of Madagascar. As for raptor birds, there are twice more forest species than savanna species.
All of that gives an incomparable importance to bird watching in Madagascar and in the Comoros.
