The Blossomcrown is distributed in two disjunct areas of Colombia: the Sierra Nevada de Santa Marta and in central Colombia on the eastern slopes of the central Andes. See the distribution map at Natureserve.

It is classified as Vulnerable by Birdlife International given its small range and the threats to its habitat within that range. It is found in humid forest at between 600 and 1,700 metres in Santa Marta and at higher elevations in central Colombia.

These photos are of a male bird which has a buffy-white forecrown. The female has a brown forecrown. Note also the white spot behind the eye, the pale buff tips to the tail and the relatively short and straight bill.

It seemed to be quite a shy bird and was easily chased from the flowers on which it was feeding by more aggressive hummingbirds such as Green Violetear Colibri thalassinus.
