Heliodoxa leadbeateri

NOTES

To elaborate our model we removed uncertain localities such as those localities with no coordinates and all records with coordinates laying down in sites with estimated elevations below 422 m and above 2,700 m.

The habitat suitability model generated in Maxent showed some areas suitable in climatic terms for this species in serrania del Baudo, serrania de San Lucas, Sierra Nevada de Santa Marta and the northern two thirds of the Western Andes. Those areas are not known to be occupied by this species and were deleted from our final potential distribution map.

Distribution of specimens according to BioMap suggest a zone of intergradation (1,474 km2) between subspecies parvula and sagitta in southern Huila.

Most of the distribution in the Central Andes (north from Huila) needs further collections to clarify better if subspecies parvula is the one present in that area.

Assuming that the distribution of the species may have filled the complete climatic model generated, its distribution today in remnants of forest is about 54,559 km2, which corresponds to a loss of 59 % of its potential original distribution due to deforestation.
