In Vietnam, and to lesser extent in Laos, deforestation has had, and continues to have, a large impact on the availability of habitat within the black-crowned barwing’s range (5). It is therefore likely that its already restricted population is gradually declining (2). However, with so little known about its general ecology and especially its exact habitat requirements, it is not clear how significant the loss of forest habitat is for this species. It may be that it is relatively tolerant of secondary growth, grassland or scrub habitat, in which the case the scale of the impacts may not be that severe (2) (5). Nonetheless, in the absence of reliable data and in the interest of caution, particularly given its small range, the black-crowned barwing is currently classified as Vulnerable (1) (5).
