Collared crows, spotted doves, black-collared starlings, Eurasian tree sparrows hang out near Lake Ad Excellentiam . You can also find black kites or even crested serpent eagles looking skyward.’ And of course, the University Library is home to Hong Kong’s largest house swift colony. In the morning, it’s not difficult to spot the birds feeding their young. Autumn to Spring Best for Bird-watching Autumn is here and so are migratory birds. Professor Lam said the best season for bird-watching has just begun. And apparently, the idiom ‘The early bird catches the worm’ is true. ‘Birds look for food after sunrise. So, you can see more birds from 7 a.m. to 8 a.m. than at any other time in the day. Evening is also suitable for bird-watching as some birds hunt again to avoid going hungry during the long night,’ he said, ‘After hunting, they stay in woods to rest. Only humans are stupid enough to work when they are full.’ Mentality Over Perception Professor Lam remarked that bird-watching isn’t only about the eyes; we have to adjust our mentality in order to be able to spot birds. ‘We have to treat birds as our friends and equals, and thank them for allowing us to watch them. ‘We should relax while being alert, use our hearts rather than eyes, listen for bird song and bird call, and try to detect tiny movements of living organisms around us. Then we should trace our observations to the birds, and finally, pick up our binoculars. It’s wrong to use binoculars from the start because they limit our vision.’ He added that bird-watching can be done with the naked eye. In general, a pair of 10x magnification twin- tube binoculars would suffice for observing the form and behaviour of birds on campus. Connection Between Birds and Humans Is it true that bird-watchers should avoid colourful clothes as bright colours scare the birds away? Professor Lam said, ‘Not exactly. That said, birds are very sensitive to movement and flee quickly. If you wear brightly coloured clothes, they may avoid you.’ He stressed that the most important code of bird-watching is to respect the birds. Never disturb their activities and living environment. Don’t attempt to clear the barriers protecting the nests to take a better look. ‘We should stay quiet and leave after watching for a while. Don’t make any noise even if you don’t see birds.’ The veteran bird-watcher said that his favourite activity is also extremely rewarding. ‘Walking among greenery is a pleasant experience that cures one of “nature-deficit disorders”. Beginners are not able to identify the different species. They have to record the form and characteristics in order to look them up in books, before going back to watch again. Repeats in observation and research is a process of learning that’ll lead to new discoveries. Furthermore, one has to observe very carefully in order to identify bird species and their characteristics. This improves one’s observation skills, and is especially beneficial for children.’ Professor Lam’s face lights up when he’s talking about bird- watching. It just goes to show how enjoyable the activity can be for some. He said that bird-watching in its most sublime form is when you and the bird stare into each other’s eyes in mutual observation and appreciation, and when you take yourself for a bird for a brief moment.’ Obviously not easy, but never mind. Let’s just start by admiring the beauty of the birds on our campus. 普通翠鳥 Common Kingfisher 小白鷺 Little Egret 白頸鴉 Collared Crow 黑領椋鳥 Black-collared Starling 喜鵲 Common Magpie 麻雀 Eurasian Tree Sparrow 珠頸斑鳩 Spotted Dove 白鶺鴒 White Wagtail Photos by Samson So 認識更多中大校園雀鳥及其特徵和行為，請參閱《中大樹木計劃》網頁 To know more birds on campus, please go to CU Tree Project www2.cuhk.edu.hk/GreenEducation/tabid/90/Default.aspx
