The Pantanal 30 starts today: an image a day for 30 days of the stunning wildlife of the Pantanal - Brazil's huge wetland. Today is the Toco Toucan (Ramphastos toco), which is the bird with the largest bill in the world relative to its body size (30 to 50% of its body surface area). Deforestation in Brazil has actually helped this species, which prefers open habitats. Follow the series on Twitter (@_MartinGrace) or Facebook (@MartinGracePhotography).
