Since 1957, Lord was involved in swiflet research. Till todate, more of his works has not been shared. This is the opportunity for those interested to share his works...

21. troglodytes esculenta Plain tailed linchi Glossy swiftlets Two species in Malaysia White spots on tail feathers
22. Speciation among Glossy swiftlets, Collocalia C. esculenta L. 1758 C. linchi H & M 1834 C. troglodytes Gray 1845 All build self-supporting cup-like nests of strands of plant material, fixed with a basal band of edible nest ‘cement’
23. Collocalia : glossy swiftlets 1. White-bellied swiftlets C. esculenta
42. White nests ( ‘vestitus’) Salai cave, Baram, Sarawak Photo Lim Chan Koon
43. White nests are highest value These nests are composed almost entirely of edible nest-cement, with no more than a few feathers adhering to or incorporated, Raw nests may be worth RM 7000 per kg of ~100 nests
44.
45. There are also two species of “white-nest” swiftlets This is the typical dark-rumped form Aerodramus f. fuciphagus of Java
47. AMNH 634703 f Coll. H.C. Robinson, Koh Pennan (Phangan Is) 13 June 1913. L Wing 112 No moult. Grey rumped, or Germain’s swiftlet Aerodramus germani Coasts and islands from Hainan (China) & Vietnam, Thailand, Malaysia, to Andaman Is Grey rump, with dark shaft streaks

58. Karst limestone of interior Borneo Surprisingly, no records of Aerodramus swiftlets in any cave in Msia Semenanjung Caves in limestone and other rocks are the natural nesting sites of swiftlets.
59. White cliffs Dizzy heights Twisty tunnels The work of nest collectors is very hazardous
60. A. (f.) vestitus Salai cave, Baram, Sarawak Rarely can nests be gathered by hand Lim Chan Koon
61. Walkways in cave interiors are made of natural materials Panguma cave, Niah, Sarawak Black-nest colony
62. Nuar at Panguma Fixed climbing aids also use available natural materials
72. House in transition C. linchi > A. fuciphagus Glossy swiftlet nests White nests
73. New nest house at Bayang Kara, Kaltim. Original wooden house with C. esculenta nests enclosed in concrete shell; eggs imported from W. Java Ventilation holes Cladding, for coolness Javanese technology exported
74. Spontaneous occupation of buildings by edible/white-nest swiftlets Penang & Butterworth Kuala Terengganu Bintulu Melaka Singapore Java (multiple instances) Banjermasin Since 1890
75. Spontaneous colonisations of buildings in Pen. Malaysia Penang (1947) K. Terengganu (1974) Kuala Lumpur (1948) Known start dates Melaka (1953) Singapore (1935)
76.
77. Since 1990s swiftlet-farming has relied on the direct attraction of free-flying birds into specially constructed houses
82. House-farmed white-nest swiftlets of Sarawak do not resemble either of the wild species Aerodramus germani on islands Aerodramus (f.) vestitus of inland caves
105. The Malaysian government has recognised that the husbandry of swiftlets in houses falls into the remit of the Veterinary Department, including issues such as animal welfare and cruelty

107. Breeding cycle & salivary gland activity Females Males Gonads active Salivary glands inactive Gonads inactive Salivary glands active
108. White-nest : coordinated breeding Lim Chan Koon
120. Corner nests are 3 rd -grade in the market, which prefers 180º nests
121. Studies of behaviour at the cave mouth shows that swiftlets feed only during daylight hours, and that weather (especially rain) is an important determinant of the birds’ activity. It is likely that prolonged rainy weather is detrimental to their ability to feed
123. Analysis of food balls fed to nestlings, compared with passive samples of aerial insects, shows that swiftlets are selective feeders, taking a very wide variety of arthropod prey
124.
125. Could managed, selective breeding of house-farmed birds improve the stock, e.g., female fecundity, nest weight or quality, disease resistance ?
126.
127. In the scenario of this newest domestication, with the backing of sound husbandry and good science , rational planning can ensure the perpetuation and sustainable management of this important biological resource.
