Agree with 1-4 but 5 is surely a bulbul, maybe cream vented rather than red eyed as iris does not appear two-toned

Yes, could be - tail looks too long for WCB, and coloration is completely wrong too. I forgot Cream-vented has red eyes on Borneo. Good match here (note the bill shape and colour):

Hi all,
Roberto, #1&2 different Swift's? #1 looks like an esculenta, sea level inhabitant n. Borneo. #2 generally impossible but black-nest feeds over open areas in n. Borneo.

Andy , thanks for the I.D. help , on number 4 i,ve seen the female Brown-throated Sunbird in my guide , but the beak it,s quite different from this one , slight curved and bigger .
Bryon, I've tried blowing up and adjusting the image of the first swiftlet, and I'm not seeing the contrasting pale underparts and more uniform dark head of a typical Glossy Swiftlet. I'd also expect the tail to be shorter and squarer and contrast with the whitish belly. It looks more like one of the three echo-locating swiftlets to me. I don't think there are any other possibilities - Bornean/Cave Swiftlet (linchi), if a full species, only occurs at high elevation and closely resembles Glossy, and it's not Waterfall Swiftlet either.
Re no. 4, I would say beware field guide illustrations! Bill length is variable in sunbirds, and Brown-throated generally has the shortest and straightest. If you blow up your image, you'll see that the bill is actually longer than it appears at first glance (partly broken?) and all-dark. It also shows the short square tail, red eye, broken yellow eye-ring (more of a double crescent and very distinctive), plain yellow underparts and olive-brown upperparts of Brown-throated.

Hi all,
crikey, Andy too deep here for me involving linchi! Would have thought most could see the structural differences between collocalia and aerodramus. Black-nest, @ #2 subjectively is a relatively hefty swift, if this is what it is. If you look at the colonies young esculenta is not glossed deeply either blue or green. It also is not as contrasty as the adults. Using a electronic database to Id. these has evidently not shown their true distribution. Perhaps this was merely a matter of nomenclature? Glad to see Roberto has got some answers, though.
