Let me talk about Bahama Pintail or what you called White cheeked pintail . As what I can see when I check out the photos of this animals, I can say that it's a pretty bird that has an ability to swim in the water. Pintails are endemic to the Neotropical realm. They are widely distributed and locally common in the Caribbean and mainly coastal regions of South America to southern Chile and central Argentina. This kind of bird occurs on waters with a degree of salinity, such as estuaries, brackish lakes and mangrove swamps. They feed on aquatic plants and small creatures obtained by dabbling. They lay eggs on the ground under vegetation and near water. The scientific name of this species is Ana bahamernisis. To identify the male and female pintails is, the females slightly duller feather color and having a lighter colored bill. The males has a brighter colored feathers and bill. Both have white throats and white cheecks and the rest of the body is light brown feet and legs are gray.
Talking about reproduction, the male can breed all year around. The female and male both go through vent sexing. The breeding season begin from February to June but varies depending upon rainfall and availability of invertebrates. The baby duckling are ready to fly in about 6 weeks after being born. The nest of this species are made of a scrape on dry land concealed under a clump of vegetation and sometimes a great distance from water. The average length of this pintail is 38 to 48cm and the average weight is 524g/F503g.
