In addition to the obvious gaps noted in this species account relating to molt, predation, nesting phenology, and demographics, the following research needs are identified in the literature.
- Evaluate reproductive success in terms of habitat variables to better understand population dynamics and the implications for conservation (Latta et al. 2000, 2002).
- Determine the patterns of cone development of Hispaniolan pine (P. occidentalis) and how these patterns affect the population dynamics of Hispaniolan Crossbill (Benkman 1994).
- Determine how soil properties and geophagy function in the ecology of Hispaniolan Crossbill (Latta unpubl. ms.).
- Investigate the relationship between pine cones and insect communities to evaluate insect intake in nestlings (Latta et al. 2002).
- Develop a more accurate measure of the status and distribution of the species and its habitat (BirdLife International 2008).
