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.
