Shorebirds

原文摘录   · · · · · · 

• There are two basic points which all birdwatchers should bear in mind when identifying waders. Firstly , there is no substitute for getting to know thoroughly the common species. Usually there are only a dozen or so species in this category in any one locality and, once their behaviour, habits, calls and variations of plumage have been learnt, then it becomes much easier to locate and identify the scarce waders. Secondly, by definition, rare waders are very few in number! The great majority seen will be of the commoner species， so when identifying an odd-looking wader it is prudent to consider seriously an unusual individual of a common species before the possibility of a rare one. Careful unbiased observation is the key to successful identification. (查看原文)
