scenery as well. The backgrounds of the groups were painted by Bruce 

 Horsfall, Charles J. Hittell, J. Hobart Nichols, Carl Rungius, W. B. Cox 

 and Louis A. Fuertes. The artificial foliage and flowers were made in the 

 Museum laboratories from material collected in the localities represented. 

 Each group is fully described in the label attached to the case. See also 

 Guide Leaflets No. 28, No. 1 and No. 22. Beginning with the case at the 

 right of the entrance and passing on to the right around the hall, we find 

 the groups arranged in the following sequence: 



The distribution of birds, notwithstanding their powers of flight, is 

 limited in great measure by climate. Thus in traveling from Panama 

 north to Greenland there are zones of bird life corresponding 

 to the zones of temperature. This condition is illustrated 

 in the mountain of Orizaba in Mexico, where in traveling

 concerned is an epitome of all the groups in the hall. 



Among our most beautiful and graceful shore birds are the terns and 



gulls, which (because of their plumage) have been so cease-

formerly there were thousands. The group represents a section of an island
