Birds of the karst
Limestone creates relief, drainage, and refuges: karst is a habitat network.
Reviewed:Geology organizes communities.
Mogotes, sinkholes, valleys, caves, and cliffs create variable moisture and structure. Río Abajo represents humid karst; the southwest links limestone and dry forest.
Vegetation, rain, continuity, and disturbance change the list. Use habitat to form expectations and confirm with voice, shape, and behavior.

01
Humid northern karst
Río Abajo offers canopy, cavities, and corridors for parrots and forest birds such as Woodpecker, Tody, Vireo, and Bullfinch.
Public roads show only part of the mosaic. Do not enter caves, aviaries, or closed land or follow flocks into management areas.
02
Dry karst and night
Puerto Rican Nightjar depends on dry and limestone forest and is detected by voice. Hearing it does not justify approaching or repeated playback.
Listen from permitted routes with discreet walking light. Preserve darkness and avoid altering feeding, courtship, or nesting.
