After finding/introducing the above park guardians, you can get an English code. After collecting the English code, try to guess the secret puzzle on the homepage. ***The answer is at the end of this page***
1. Alexandrine Parrot (P) 
Features : About 42 cm long, with red collar, red shoulders and yellow eyes. Vegetarians: It feeds on fruits, seeds and nectar.Influenced by the cage-keeping trend, parrots in Hong Kong are either released birds or escaped cage birds. Parrots in Hong Kong are territorial. There are white sulphur-crested cockatoos in the Central District of Hong Kong Island, and Alexandrine parrots and red-collared green parrots in Kowloon Park. When flying, it looks like a cross. It is an introduced species from other places and is a wild resident bird.
Alexandrine Parakeets and Red-collared Green Parrots love to stand on the structures by the pool, see if you can spot them!
2. Tree Sparrow (L) 
Omnivorous bird; insects are active frequently in spring and summer, and plants rarely bear fruits, so insects are the main food. In autumn, various plant crops bear fruit, and the main food is plant seeds and fruits. In recent years, sparrows living in cities have already fully adapted to urban life and learned to find food discarded by humans.3. Red-eared Bulbul(A)
Red-eared Bulbul, commonly known as "High-crowned Bulbul", is a common bird in Hong Kong. It also has red spots on both sides of its ears and obvious red spots on its buttocks. It likes to move among the woods and feed on fruits and insects.4. Night Heron (Y)
Although its name contains the word "night" in it, it is often very active during the day. It is a medium-sized egret with yellow feet. The adult bird has a dark green head and back, and grayish-white wings and abdomen, which are in sharp contrast. During breeding, there are two to three long, white ornamental feathers on the back of the head. When hunting, it will retract its neck and stand by the water waiting for an opportunity to find food.5.Stonewall Tree(E)
The stonewall tree species has a twining growth habit and can grow and take root on the vertical surface of stone walls. It adapts to this harsh environment and grows into large trees, beautifying the landscape. The main tree species include fine-leaved fig, pen-shaped fig, opposite-leaved fig and large-leaved fig.This type of stone wall is a traditional Chinese masonry method used to build a variety of retaining stone walls to provide platforms and consolidate disturbed hillsides. Since there are many joints between the stones of the stone wall, and there is soil and groundwater seeping behind the wall, which can provide space for plants to grow, stone wall trees can take root and grow on the vertical surface of the retaining stone wall. Unfortunately, as the traditional stone wall construction techniques have been lost, no new stone walls are being built using traditional techniques. Stonewall trees have thus become a unique cultural heritage that deserves and requires our proper management.
Tree roots growing on the surface of a stone wall will also expand their growth range, extending the roots responsible for absorbing nutrients to the soil at the base or top of the stone wall to absorb more water and nutrients needed for growth. The roots on the surface of the stone wall will also merge into one where they overlap, forming a unique root network that grips the surface of the stone wall. Some tree species develop lignified aerial roots that, when in contact with the soil, become bracing roots, providing additional support and making the stonewall tree more stable.
6. Bauhinia (V)
Bauhinia bracteata was first discovered on Hong Kong Island and was chosen as the regional emblem because of its beautiful flowers. Research indicates that Bauhinia bracteatum may be a hybrid of Bauhinia rubra and Bauhinia rubra, so its seeds cannot develop normally, so it is also called a sterile tree. Since it cannot reproduce naturally, it is necessary to artificially graft the branches of Bauhinia onto the trunks of other Bauhinia plants for reproduction. If you observe carefully, you will find that the trunks of Bauhinia bauhinia often have traces of joints, and sometimes a Bauhinia bauhinia tree will also grow other Bauhinia flowers at a lower level.
7. Camphor tree (O)
Camphor is an excellent insect repellent substance in camphor trees.Insect anthelmintic: The leaves and trunks of camphor trees are rich in camphor oil. Many insects hate the smell, so it can prevent insects from eating them. In the past, people would use this property of camphor wood to make wooden boxes and wardrobes (camphor bars), or make mothballs and place them in wardrobes to repel insects. With the development of technology, the stink balls used to repel insects have now been artificially synthesized.
Animal granary: Many insects are afraid of the smell of camphor trees, but a few Lepidoptera insects such as the camphor moth and the blue swallowtail butterfly are not afraid of the smell of camphor oil. Their larvae feed on camphor leaves. If you pay close attention, you may find camphor moth pupae and blue swallowtail butterfly larvae on the camphor trees.
8. Banyan tree on Park Lane Avenue (L)
A century ago, it was a rural area with dense shade trees. At that time, Governor Nathan knew that Kowloon would develop, so he imitated European city design when building the road. Trees were to be planted on both sides of the main road. From Tsim Sha Tsui to Yau Ma Tei, it is estimated that nearly 200 banyan trees were planted. Kowloon developed rapidly in the 1950s, and the two rows of trees on the roadside gradually gave way to shops. But the worst mistake happened in 1975, when Queen Elizabeth II visited Hong Kong, some councillors said that the exposed tree roots on Nathan Road were ugly, so they built a one-meter-high stone curb and piled mud on the tree stumps.Ficus microcarpa is one of the most common native trees in Hong Kong. It provides shade and wind protection, and also provides a valuable habitat for birds. Its fruits are also food for many wild animals, such as small birds such as white-crowned bulbuls and acacias, as well as fruit bats. Growing in the air, aerial roots can absorb moisture from the air and also have the function of breathing. If aerial roots extend into the soil and play a supporting role, they become prop roots.
The "fruit" of the fig tree is also called "hidden fruit", which means the fruit hides the flower. The trunk or branches of the banyan tree are often covered with small round "fruits". These hidden fruits are the receptacles of the banyan tree, and the flowers are hidden inside the "fruit". Because the flowers of the banyan tree are hidden inside the receptacle and isolated from the outside world, ordinary butterflies, bees or birds cannot spread pollen for it, and the task of reproduction can only rely on the tiny fig wasps.
Fig wasps Fig wasps belong to the order Hymenoptera, and their entire lives are inseparable from the fig fruit. The bees stay in the fig fruit from hatching, growth, pupation, emergence to reproduction. The male bees will only live in the fig fruit throughout their lives, while the female bees will leave the fig fruit where they were born and fly to other fig fruits to lay eggs. Since the drone will never leave the fig until it dies, it does not need to fly at all and its wings have degenerated.
