I have gotten birds in my rehab centre in this condition, and they are truly in a life and death situation. They can be helped with careful attention to gradual nutrition in a rehabilitation situation, but as for the ones out at sea, unless they find food soon, they are close to the end of their lives. I have also heard of oiled birds jumping into boats, most think its an attempt to get out of the cold water or to not drown, as oil contamination robs them of both their waterproofing and thermoregulatory abilities. Again, with careful care in a rehab situation, these birds can be brought back to a releaseable state, even the very thin ones. On a precautionary note, if anyone finds an extremely thin/dehydrated bird, its important to NOT feed it until its hydration/fluid loss needs are met. Trying to summon the water from its body necessary to process that item, may be the straw that breaks the camel's back. They need careful rehydration before being offered food of any sort.

I have never read such a thing, and cannot guess why a restful stopover should have hurt that warbler. The long and the short of it Paul is that these birds have probably reached a metabolic point of no return. Once a migrating bird's fat reserve is gone it begins to metabolize muscle protein. If they can't land to replenish their reserves or too much muscle is metabolized they may simply be beyond the point of recovery if they finally do land on dry land. Helene Van Doninck of the Cobequid Wildlife Rehabilitation Centre and the list's 'resident' veterinarian may have more insight on this. I don't think the stopover hurt the bird in your example, rather I think that it had reached the point where the food it managed to catch on the boat was not sufficient to keep it alive. As far as birds falling into the water once they have landed on the boat go, they land on the boat because they have to (running out of energy), they leave because flying away is a response to the danger they detect (people) , and they fall into the water because they no longer have the energy to sustain the flight.
