What is significantly missing from the Continental Drift Hypothesis verses the Theory of Plate Tectonics? 

The population size of many species including wood ducks, Canada geese, sandhill cranes, and several egret and heron species was dangerously low at the beginning of the 1900s.  What conservation intervention resulted in a population rebound for these species, so that now, all have healthy populations that are in no danger of extinction?

a) How is the brain of birds different from the brain of mammals  in terms of how it looks, superficially?    b) Researchers have examined the density of neurons in the brains of some birds in relation to the birds’  activities at different times within the annual cycle.  Describe what has been found about how  neuron density within the brain changes at different times of the year, and provide an example of how this change contributes to the studied species’ fitness (i.e. contributes to  its survival or reproductive success)
