Priorities for Future Research

The Purple-throated Mountain-gem has very broad, plastic dietary preferences and acclimatizes rapidly to accommodate changes in their environment (Feinsinger et al. 1988). Indeed, the population density of this species at a given locality experiences only minor declines with mild, patchy habitat fragmentation (Feinsinger et al. 1987). However, little is known about the reproductive and courtship behavior of the Purple-throated Mountain-gem (Snow 1977). Population density within feeding arenas during the non-breeding season tells us very little about the long-term reproductive success of the population. Perhaps courtship, mating and nesting habitat preferences are less malleable than feeding preferences and are less able to cope with the continual deforestation and human-development taking place in Costa Rica and Panama. Therefore, further research of the reproductive behaviors of the Purple-throated Mountain-gem is essential to future conservation efforts.
