Tur THICKET ASSOCIATIONS. 
No real mesofytic or xerofytic thickets are present in this 
region. A few birds which are elsewhere typical of such 
thickets hav adapted themselves to the more or less similar 
conditions which do exist in this vicinity, that is to say, to 
the hedges and the small orchards in the vicinity of houses. 
With the exception of three or four of locust (Robina 
pseudo-acacia) hedges are of osage-orange (Maclura pomu- 
fera), which not only fulfills the ordinary purpose of a hedge 
but also seryes as a wind break, preventing excessiv wind 
action on the mobil sand. To accomplish the latter purpose 
the osage orange must be allowed to develop to good size, 
which incidentally furnishes ample protection to many birds.
