 BIRDS OF LOGWOOD-THATCH PALM-RED BIRCH FORESTS.-As plant
species diversity increases from a logwood forest to this formation, so do
the breeding and wintering bird populations (Table 7). Probably the
Haematoxylon-Thrinax-Bursera formation contains a greater food diver-
sity and more strata and feeding niches to support the avifaunal complex.
This formation contains, among other forms, two breeding species of
doves, two woodpeckers, three flycatchers, two vireos, and two warblers.
Partitioning of food resources by these pairs will be discussed in a later
section. Again, a significant invasion by wintering warblers is character-
istic of this formation.
 BIRDS OF LIMESTONE FORESTs.-As a whole, the limestone forests of
the Cayman Islands support a relatively great variety of breeding birds
(Table 8). For all three islands, 17 bird species breed in this formation;
