Hi,
I am visiting Singapore for the last two weeks in April. Have all the migrants left by this time? Two other queries - where is a good location for Asian Palm Swift.
I have been to Singapore a few times - what is the best way to distinguish House Swift and Swiftlets if seen from below - i.e. white rump on House Swift not visible - should the white throat still be noticeable, is the difference in tail obvious or is there any other birding techniques.
Thanks,
AJ
