 One side of a road contained 2.4 acres of limestone bluff forest and the
 other side, 4.8 acres of a scrubby woodland (not a logwood forest, how-
 ever), including some house sites (Table 11). The limestone forest
 contained seven bird species, virtually the same species composition as
 observed in censuses of limestone forests at inland sites (Table 8) on this
 island. Furthermore, with the exception of Columba leucocephala, there
 is good agreement between the density figures in Table 11 and the
 relative abundance scores in Table 8. Both methods revealed high popu-
 lations of Elaenia martinica, Coereba flaveola, and Dendroica vitellina,
 with lower values for Zenaida asiatica and the two vireos. The "scrub
 woodland" census showed high numbers of Coereba flaveola, Dendroica
 vitellina, Elaenia martinica, and Tiaris olivacea. The presence of Tiaris,
 Mimus polyglottos, Columbina passerina, and Ardeola ibis indicates a
 disturbed community from which the native trees and shrubs have been
partially cleared, resulting in grassy or bare areas utilized by and essential
