total of 44 observation journeys were carried out with a minimum duration of 1 hour and a maximal of 4 hours and 20 minutes (mean

hemisphere. Among the observed migrant species four belonged to the Charadriidae family: Charadrius semipalmatus, Charadrius
wilsonia, Pluvialis squatarola, Pluvialis dominica; eleven to Scolopacidae: Calidris alba, Calidris pusilla, Calidris fuscicollis, Calidris
canutus, Arenaria interpres Numenius phaeopus, Tringa flavipes, Tringa melanoleuca, Actitis macularia, Catoptrophorus semipalmatus,
Limnodromus griseus. Ardeidaes observed in mangroves can be considered residents, in spite of the variations presented by some species
such as Egretta thula, Florida caerulea, Casmerodius albus, Butorides striatus, Nyctanassa violaceus and Bubucus ibis.
