If you're planning on buying a small pet for your kids or family or are looking for a pet that is cute, friendly and fun, then you should consider a sugar glider (蜜袋鼯). It lives in Australia, Indonesia, New Guinea and Tasmania.

Sugar gliders are known by this name because they are fond of sweet food. Sugar gliders are also known as “pocket pets” because they're small in size and they like being carried in pockets. That is why many sugar glider owners keep these animals in their pockets to carry them wherever they go.

Sugar gliders are covered with the patagium (翼膜)，which looks like a parachute (降落伞) when they spread out their hands and feet, making them move in the air. Another attractive feature of sugar gliders is that they have big toes (脚趾) on their back which help make them stay on the tree.

It's known that sugar gliders are extremely lovable and social. This is why these pets get along well with their owners and their families. If you don't spend much time at home, the best idea is to keep another sugar glider pet. Sugar gliders aren't like other pets that can get used to anywhere in the house. They need a special and large area to live. So, you should get a comfortable and big space for your special pet.

The average lifespan（寿命）of sugar gliders is around 12 to 15 years. They' reactive pets that love to jump and glide. But the owner has to give enough care and love to them in order to keep them healthy. Sugar gliders are wonderful pets to keep. They're fun to watch and play with.

The ocean waters rise and fall along the coast. This movement is called the tide (潮汐). When the tide comes in, the ocean rises. The rocks along the coast are covered in water. When the tide goes out, some of the salt water stays behind in large holes in the rocks. This causes tide pools. The animals that live in tide pools, such as crabs, sea stars, and mussels (淡菜), have to get used to changes in the water. They must face large waves, the hot sun, and hungry meat-eating animals.

When the tide is high, animals in tide pools are covered with water. This protects them from the strong sun. ________ And the tide can also wash the meat-eating animals away.

When the tide is low, the animals in tide pools have to move to another world. Many of them are no longer covered by water. They are not safe because of the sun’s heat or hungry animals. There is less food for animals such as mussels in the tide pools. Mussels are protected by hard shells (壳). When food passes by, a mussel opens its shell to eat. It closes its shell when danger comes around the corner. Hungry sea stars will hit a mussel, hoping to find a way into its shell. Crabs search for dead plants and animals while keeping away from sea gulls.

In fact, life in a tide pool is also an adventure like humans.

Birding, which actually started in the 19^th century, is the practice of carefully watching and studying the appearance and behaviour of wild birds. It is a hobby for many and a sport for a few that gained a lot of popularity in the 20^th century.

Learning to correctly identify birds is one of the hardest things when it comes to bird-watching. However, there are several methods and technologies that can be used to help you.

When it comes to birding, the first thing to learn is to reduce the range of the bird toa group by judging the shape of is body and head.if you can reduce the range of a bird down to at least its grouping, then you're already half way there. Next, pay attention to the shape of its mouth and tail. Almost no two species have the same shape, so this can really help you.

Keeping in mind that the habitat you're in will also help you out a lot.For instance, you might see a Red-eyed Vireo in a treetop but chances are that if you see one on the ground then it might just be a Horned Lark. These are just a few ways of identifying a bird.

If you are still having problems or want to take the easy way out, then this is where birding technology comes in. There is a very popular app called Merlin Bird ID. It will come up with a list of possible matches after you answer a few simple questions about the bird. You can also take a picture of the bird with the app and it will offer you some matches, including its appearance, colour, habit and habitat. It's been proved to be very easy to pick up with a list of possible matches most of the time.

While bird-watching is fun, it can be challenging, but if you remain focused on what you are doing, nothing can stop you from enjoying the experience to the fullest.
