Introduction

September  is usually very hot and punctuated at interval by typhoons bringing stormy  weather and heavy rain. By the end of the month it is noticeably cooler,  especially in the early morning and evenings. In addition the humidity starts  to come down.
    
 
    Birds
        By  September second broods are usually fledged already. Migrants are passing  through Hong Kong throughout the month but  Wonderland Villas seems to see little of this though there are occasional Dollarbirds and Amur Paradise Flycatchers. Hair-crested Drongos remain very  prominent in the gully area. A large group seen one year on 27 September were  being periodically ambushed by a pair of Besras - without success. Migrating  warblers also find the Acacias in the area attractive, especially early in the  morning. Large Silver-eared Mesia flocks follow the sun off the northern slopes of the hill in the early morning.
    
 
    Other Animals
        
September  is traditionally a good month for snakes - for example the diurnal Red-necked Keelback which is often seen in this month. In 2013 a Plumbeous Water Snake was seen on 26th in the gully stream.
    
 
    Plants
        Turn-in-the-wind  is still flowering in September. In the rough area beyond the bridge at the  Wellcome end of the gully Bur Bush 
Triumfetta bartramia is also  flowering at its best. Up in the hills this month's flowering plants include  Buttercup Orchid 
Spathoglottis pubsecens and the over-sized flowers of  the Adenosma 
Adenosma glutinosum. Another plant that is very visible in  September is the Lily Tuff 
Liriope spicata. 
     
    Butterflies and Moths
    The second wave of moths begins in September after the lull months of July-August.
