(b) The report said, "A worker at the swiftlet farm carefully scrapes a small white bird's nest off a rafter."

(The most heavily harvested nests are from the Edible-nest Swiftlet or White-nest Swiftlet (Aerodramus fuciphagus) and the Black-nest Swiftlet (Aerodramus maximus); Most nests are built during the breeding season by the male swiftlet over a period of 35 days)
Quote: "Hong Kong and the United States are the largest importers of these nests. * * * The nests were formerly harvested from caves, principally the enormous limestone caves at Gomantong and Niah in Borneo. With the escalation in demand these sources have been supplanted since the late 1990s by purpose-built nesting houses, usually reinforced concrete structures [a photo]* * * These nesting houses are normally found in urban areas near the sea, since the birds have a propensity to flock in such places. This has become an extraordinary industry, mainly based on a series of towns in the Indonesian Province of North Sumatra, which have been completely transformed by the activity. From there the nests are mostly exported to the markets in Hong Kong, which has become the centre of the world trade, though most of the final consumers are from mainland China. It has been estimated that the products now account for 0.5% of the Indonesian GDP, equivalent to about a quarter of the country's fishing industry.
* The "swiftlet" is translated as 金丝燕 in the BBC Chinese report.
(c) The erport then said, "Safety concerns last July effectively halted all exports of bird's nests to China from Malaysia, the world's second biggest supplier of the delicacy."
I can not find authorative statistics. In the web there are two competing country rankings by production values: either
(i) Indonesia (80%), Thailand (10%), Malaysia (7%), or
(ii) Indonesia (80%), Malaysia (15%).
