Tolima Blossomcrown Anthocephala berlepschi



Taxonomy

Taxonomic note
Blossomcrown Anthocephala floriceps has been split into Santa Marta Blossomcrown and Tolima Blossomcrown A. berlepschi following the finding of reciprocal monophyly between the two (Loranzo-Jaramillo et al. 2014), supported by subsequent assessment of morphological differences in museum specimens, albeit with a sample size of only three for A. (f.) floriceps.

Population justification: Tolima Blossomcrown is described as rare (Renjifo et al. 2016, Züchner et al. 2019). It is tentatively estimated to have a population size between 1,000 and 4,500 mature individuals, based on the population estimate of Blossomcrown before the taxonomic split into Santa Marta Blossomcrown and Tolima Blossomcrown.

Trend justification: While the threats this species faces may be causing population declines, there is no clear evidence of the rate of decline.
