Stay with me, friend!
These birds didn't (don't) have millions of years to figure this out. If they failed on the first try - that's it - they all die! (water below)
Yes?
No?

If anybody wants a slick video presentation detailing Ceeboo's question / argument, you can see it here:

The Siberian species of the Golden Plavor migrates from Alaska to Hawaii each winter.
You imply here that any given group of Plavor
have to reach Hawaii, or they die!
This isn't the case.
Only a few Plavor go to Hawaii on their southward migration.
Most go to South Asia and Australasia:
http://en.wikipedia.org/wiki/Pacific_Golden_PloverThis wader is migratory and winters in south Asia and Australasia. A few winter in California and Hawaii, USA.
Slowly developing longer distance and more efficient migration techniques would have aided their survival over time. But in
no way was the plavor
required to fly from Alaska to Hawaii 'from the start' (whatever that would practically mean) with no other survival options available!
I know that's what the video implies, but - lets face it - creationists say all kinds of kooky stuff ;)
The plavors migration direction is generally 'south'. Most don't go anywhere near Hawaii.
Before their long-distance capacity could reach Hawaii, those that happenned to travel in that direction - yes - of course died!
But those that flew in the 'usual' non-Hawaii direction (i.e. most of them!) would have increased survival advantage using good migration flight techniques regardless. (More ground to cover, less energy used in flight to cover the same distance etc.)
As their long-distance flight capacity generally increased over time on south Asia / Australasia migration routes,
some of them were able to (eventually) make it to Hawaii.
First of all by 'going off course' or otherwise being diverted in that direction... and then solidifying into a new settled, but still rare, migration pattern.
..and, well, that's about it.
There is no problem for evolution here...
If you think there is, then please explain...
