It is planned in future Audubon Bulletins to supply this information on 
other families of local land birds, but the data below concerns only the Wood- 
peckers of the area. The table below lists the species of bird involved, the 
perching sites most commonly used (those sites seen to be used 4 or more 
times), and the percentages of total observations in which a given perching 
site was observed.

From the above, a number of interesting observations can be drawn. The 
first is perhaps the relative abundance of our Woodpeckers, based not on 
individual birds, but upon individual observations (the difference between 
individual birds and individual observations is explained earlier in this 
article). This ratio shows in the following table:
