The Ornithologist has posted his report over at Archinect.com.
What I think is most interesting in the report is the masking or camouflage of military space with artificial ecologies. By producing bird habitat, the military can prolong their presence. However, too successful of a habitat will lead to the birds' over-taking of the base, by activist protest or B.A.S.H.--Bird Aircraft Strike Hazard.
The Swiftlet is interesting because it uses echolocation to navigate in combination with eyesight. Bats also use echolocation but the sonar emitted is typically at frequencies higher than humans can hear.
The bird nests are edible, too. The industry for swiftlet bird nests is already on the rise in Malaysia. There is even a website which allows you to download Swiftlet sound for free. In this way you can "seed" your own swiftlet farm, broadcasting these bird calls to attract the birds to make their nests in your abandoned building (or military base, as it may be).
Swiftlet farming, like the US military, thrives on the production of ghost ecologies.
