Writing Task - IELTS The chart shows what kinds of birds species can be seen in Woodchuck country, depending on the season (winter or summer). Three of the eight species are observed in both seasons (cardinals, crows and woodpeckers), so they can probably say that they aren't migration birds, because they can feat on winter and summer. Four species listed on the chart (bluebirds, mocking-birds, orioles and vireos) are observed just in the Woodchuck summer. That probably means that are migration birds cause they living in the country during the summer to make their nests and breed while in the winter they fly away to another place where the weather is cold. Finally, just one specie (juncos) is observed only in the winter, and there are many alternatives to describe their behavior, perhaps juncos migrate to another are in the summer and spend their time feeding. After, they return to Woodchuck in the winter, when we can observe them.
