Additional details on Breeding :
Cambodia: Breeding began at Prek Toal began in September when seasons flood waters began to sise and ended in March when the flood waters had receded (Tingay 2006). These authors conducted a survey of this species at the northern end of Prek Toal Core Area of the Tonle Sap Lake and found 28 active nests from 6-13 December 2005. Observed breeding stages included nest-building, incubation, and nestlings, ranging in age from approximately 2 days old to almost fully-feathered chicks 6-7 weeks of age. No fledglings were observed. Most nests contained nestlings or eggs near hatching in October-November when flood waters weere at their peak.
Malay Peninsula: Eggs have been recorded in Kedah and Singapore on 8 and 12 January, and nestlings in Narathiwat on 15 March (Gibson-Hill 1950, Wells 1999).
Cambodia: Nests were more likely to be found in relatively tall trees with an open crown structure (Tingay et al. 2010). Among a sample of 34 nests found in 2006, 28 nests (82%) were in Prol trees (Diospyros cambodiana), and three (9%) each were in Chrakeng (Mallotus anisopodus) or Taor (Terminalia cambodiana) trees (Tingay et al. op cit.). Nests were also relatively close to permanent water and negatively associated with the location of human villages.
Malay Peninsula: 2 eggs (Wells 1999).
Malay Peninsula: Rough-textured and plain glossless white (Wells 1999).
Malay Peninsula: 64.9 x 50.8 and 63.9 x 50.5 mm (n = 2) (Wells 1999).
