- Given the lack of information on the influence of tide on estuarine birds, this study analyzed the variation of abundance, diversity and richness, in response to the tidal cycle in an estuarine lagoon in the northern part of Ilha Comprida, south coast of São Paulo State. The method used for numerical scores was the fixed point. Correlation coefficients were determined between the number of individuals, richness diversity and shifting of the tide. There was a strong negative correlation between the number of species present (r = -0.71) and the total number of individuals (r = -0.80), when correlated vs. tidal range. As for diversity, there was a very weak negative correlation with tidal amplitude (r = -0.43). Some species depend more tham others to tide movement in the lagoon of Ilha Comprida, and are mainly conditioned with the type of food, size of the bird, beak size and legs.
