For what it is worth, Philippines also has many (16) species of swifts and
swiftlets (including 2 treeswifts) and at least some of the species are
common and easy to watch, not unusually in mixed flocks but often far from
easy to identify.

Kirri, Your bird is the White-rumped Swiftlet, Closely related to the
Australian Swiftlet.
Bill your two birds are the Glossy and Uniform Swiftlets as you surmised.
Vanuatu has all three species, but if you want more, go to New Guinea .
That island has 9 species of swifts and swiftlets.
Shirl & I have just gotten back from working on the Australian Swiftlets at
Chillagoe for 5 weeks, and can report that although 4 colonies went extinct,
most have recovered from the caves filling with water a few years back. The
worst declines appeared where cat predation coincided with the damage done
by the flooding.
Happy birding
Mike
