(10 points) Benefits: reduce the cost of existence: more favorable food, shelter, nesting sites, environmental conditions. Costs: flight is energetically expensive, no/little opportunity to feed, physiological demanding (normal weight, gain fat, burn it fast, repeat 2x / year), cross hostile environments (oceans, deserts), many unknowns (predators, food sources, roost sites), unpredictable weather.
