In a "vanishing lake (or creek)" scenario, I would expect the properties of the 
substrate to be critical once water levels are so low that an animal exploiting 
drought-constrained fish would necessarily contact them - e.g., in the SE US a 
very yielding but almost completely non-adhesive sediment is common beneath 
ponds in forested areas - it is inconvenient to me when more than meter deep, 
but I cannot see that a vertebrate could be trapped, even a small one with 
splayed feathers. Perhaps the feathers and wings might even be helpful. 

OTOH, certain clays mixed with water might turn feathers into heavy clumps of 
mud,  and reduce mobility / cause exhaustion, especially in a small 
sight-hunting animal more accustomed to gliding or flying from tree to tree.
