LC
Sombre Tit Poecile lugubris



Justification

Justification of Red List Category
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend is estimated to be stable, the population is therefore not thought to approach the thresholds under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Trend justification
Both increases and decreases in regional populations have been noted in recent years (del Hoyo et al. 2007). The European population trend is currently estimated to be stable (BirdLife International 2015).

Ecology

This species inhabits dry maquis areas of scattered trees and bushes, including olive (Olea) groves, wild plum (Prunus) orchards and other fruit trees and vineyards. It also uses parkland areas of open oak (Quercus) forests including scrub oak, beech (Fagus), willows (Salix) and poplars (Populus) and conifers, particularly spruce (Picea) and cedars (Cedrus), especially in areas of rocky limestone hills. It breeds from March to early August and is monogamous. The nest is a cup of wool, plant material, bark strips, animal hair and feathers, placed in a hole in a tree, often in rotting wood in a fruit tree but also among rocks on banks and will use nestboxes. Normally lays five to seven eggs. The diet is principally insects although it does consume seeds as well.  The species is resident but there is some evidence of altitudinal movements in parts of the range (Gosler and Clement 2007).

Threats

In Armenia, the species is threatened by an increasing number of wild fires and the use of toxic agricultural chemicals (Aghasyan and Kalashyan 2010).

Conservation actions

Conservation Actions Underway
Bern Convention Appendix II. There are currently no known conservation measures for this species in Europe.

Conservation Actions Proposed
Although this species is not currently threatened monitoring should be implemented to detect population changes and research undertaken to inform future conservation measures.
