New England, the northeastern part of the U.S., is a great place to go birdwatching. There are mountains, forests, rivers and lakes, and a long seashore. On Monday I went to see a puffin, sometimes referred to as the penguin of the north. It is a small black and white sea bird like the penguin, but it has a big orange beak like a parrot. Unlike penguins, puffins float on the sea and dive for fish using their wings for propulsion. (by Prof. Douglas Jarrell)

If you go to New York City now, you can go around the city on a bicycle. There is a new program called Citi Bike. You can find bicycle stations in many different places. Use your credit card and buy a membership for a day, a week, or a year. Borrow a bicycle at one station, and then leave it at another station. Bike-sharing started with free bicycles in Amsterdam in the 1960s, but now most cities charge fees. It’s a great way to travel when the weather is good.(by Prof. Douglas Jarrell)
