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 
Orizaba 
to the zones of temperature. This condition is illustrated

in the mountain of Orizaba in Mexico, where in traveling 
from the tropical jungle at its base to its snow clad peak the naturalist finds 

White pelican from Klamath Lake Group, Oregon. One young bird is illustrating 
its amusing method of procuring food from its parent’s throat

continent. Thus the Orizaba group so far as the distribution of life is 
concerned is an epitome of all the groups in the hall. 
Among our most beautiful and graceful shore birds are the terns and 
Cobb’s Isl gulls, which (because of their plumage) have been so cease-
