They don't lose their leaves because of the humidity in the forest.
The answer is "The population of the burrowing owl may increase in its new surroundings".
The offspring had a smaller range of beak depthsfrom smallest to largestthan their parents (black bars).The overall beak depths of the 1978 offspring population are larger the original 1976 population.In 1978, the offspring population is larger than the initial 1976 population before the drought.<span>The finches that survived the drought (black bars) had offspring with much larger beaks.
</span>n both droughts, smallbeaked medium ground finches had the highest survival rates.In both droughts, largebeaked medium ground finches had the highest survival rates.Both droughts events provided strong natural selection on medium ground finch populations.Both droughts resulted in changes to food sources that favored the survival of some medium ground finches over<span>others.</span>
