Mammals including Jaguar at Pantanal
The best time to observe wildlife is from July to October (dry season). The lack of rain diminishes the lagoons, revealing the flat grounds and aiding transportation by land. The fields begin to dry, providing vast grazing areas where mammals search for food and water in the remaining water puddles. This is the breeding season for birds – Among the common mammals we can find the Capybaras, Crab-eating Foxes, and the Grey-brocket, Pampas deer and Giant Anteaters, Crab-eating Racoons and South-American Coatis

Birds at Pantanal
February to June and September to November
Birdwatching in the Pantanal is good all year round. The majority of the birds are residents, and they move within the Pantanal according to the water level. The best periods though are from February to June, when the water is receding and there is a higher concentration of birds on the water holes, and September to November, the breeding season - their plumage is at their best condition and their calls can be heard throughout the Pantanal.

July to October : This is the best time to observe Humpback whales at National Marine Park of Abrolhos and Praia do Forte in the state of Bahia.
