Santa Marta Blossomcrown Anthocephala floriceps



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: Santa Marta Blossomcrown is described as common to uncommon (Renjifo et al. 2016, Züchner et al. 2019). It is tentatively estimated to have a population size between 500 and 2,500 mature individuals, based on the population estimate of the Blossomcrown before the taxonomic split into Santa Marta Blossomcrown and Tolima Blossomcrown.

Trend justification: The species is thought to be declining slowly due to the degradation, fragmentation and loss of its forested habitat. The rate of decline has not been quantified.
