Priorities for Future Research

Many aspects of the biology of the Puerto Rican Bullfinch are unknown, particularly during the breeding season. We know little about nesting behavior, the possible effect of brood parasitism on Puerto Rican Bullfinches in regions where brood parasites are more common, or possible causes of declining capture rates in southwest Puerto Rico. Although it is difficult to envision the extinction of such a widespread and seemingly abundant bird on Puerto Rico, the decline of captures at Guánica to less than one-third of those in the early 1990s is cause for alarm.
