When people visit Switzerland for the first time，they look with great interest，not only at the mountains but also at a type of clock—a Cuckoo-clock，on sale there．Cuckoo-clocks are very popular with tourists looking for a souvenir．A Cuckoo-clock has a small painted cuckoo that comes out near the top of the clock every half an hour and says，“Cuckoo”．Every hour it comes out and says “Cuckoo” the right number of times．It does not get a sore throat at midnight or mid-day! Children find these clocks wonderful．Adults gradually get annoyed because the cuckoo never misses an hour or a half hour，and this makes a short sleep in an armchair rather difficult．

In Europe，the cuckoo's call is a welcome sign that summer is on the way．This is the time when the mother cuckoo flies round，looking for a nest（巢）to lay one of her eggs．She chooses a nest belonging to another bird which already has eggs．When the nest is left unnoticed for a minute or two，the cuckoo rushes down，lays an egg and hurries off．In this way，she may lay her eggs in as many as four different nests．not one of which has been built by herself．

When a cuckoo egg hatches（孵化），the baby bird is bigger and stronger than the other nestlings．Step by step，it pushes other baby birds and any unhatched eggs out of the nest．In this way，it receives all the food from its foster-parents（养父母）and has a better chance of surviving．

　　INTRODUCTION

　　The Kiwi lives only in New Zealand. It looks a bit like a long-beaked chicken, but it has no tail and it cannot fly.

　　Its tiny wings are completely hidden among the hair-like feathers. Kiwis are shy birds that live mainly in fern-filled forests. They sleep in burrows by day and come out to feed at night. They eat worms and insects that live in the soil or among dead leaves. They also enjoy fallen fruit.

　　Survival Watch

　　Kiwis are becoming rare, largely because so many have been killed by the cats, dogs and other animals that people have taken to New Zealand.

　　Kiwi Facts

　　The kiwi is up to 45 cm long, including its beak. It gets its name from its call of ki-wee.

　　The female weighs only 4 kg, but she can lay two eggs weighing about 500 grams each.

　　That's nearly ten times as heavy as a chicken's egg.

　　The kiwi is a very strange-looking bird. Its dark coat looks more like shaggy hair than feathers.

　　The nostrils at the tip of the beak can smell worms and other food several centimetres below the ground.
