Atlas of nesting birds in Bulgaria

Common Cuckoo

(Cuculus canorus)

Category of conservation concern (IUCN, 2020) – Least Concern

Population size: 20 000-50 000 calling males

 

Distribution pattern

Widespread throughout the country, including in the highest parts of the mountains. Avoids places with extensive and dense coniferous forests, especially at higher altitudes. High density of suitable hosts and a sufficient number of trees and shrubs at least 3 m high are of key importance for breeding in a given place, from which the females see the nests of the hosts.

Breeding distribution 2013 – 2020 – The distribution and the estimation of the population size of the species for the period 2013 – 2020 is presented –

Comparative distribution of the species compared to the first breeding birds atlas (Iankov, 2007): Breeding locality until 2007 | Breeding locality until 2007, confirmed after 2015 – | New breeding locality after 2015. – The breeding localities after 2015 are identified on a base of raw data from smartbirds.org.

Habitats

Breeds in various habitats, combining mosaics of trees and bushes, forest areas with meadows, clearings, roads, and other open spaces, especially at the peripheries of wetlands with reed beds and trees. Documented in broad-leaved deciduous forests, alluvial and riverine forests and brush, in bogs and marshes and other water bodies with water fringe vegetation, in all types of scrubs and grasslands, and in most of types of agricultural land and artificial landscapes (especially in strips of trees, shrubs and patches of them; orchards; tree and shrub plantations). Rarely, in mixed forests, coniferous forests, public parks and large gardens, and other places similar to their natural habitats in thinly populated villages, hamlets, urban suburbs, etc.
