Bensouilah, T., Brahmia, H., Zeraoula, A., Bouslama, Z., & Houhamdi, M. (2014). Breeding biology of the European Greenfinch Chloris chloris in the loquat orchards of Algeria (North Africa). Zoology and Ecology 24(3): 199–207. doi:10.1080/21658005.2014.934514

Abstract:

Few data are available on passerines’ breeding in farmlands in Algeria. The breeding biology of the Greenfinch was studied in the loquat orchards to describe the timing of breeding, clutch size, number of nestlings hatched and fledged, assess nesting success and the main causes of nesting attempt failure, and investigate nest placement in the loquat trees. Nests were monitored intensively to quantify the number of nesting attempts and territory densities. The breeding season extended from mid-March to late May. Mean clutch size was 4.37 ± 0.04, number of hatchlings was 2.62 ± 0.15, and number of fledglings per successful nest was 3.44 ± 0.16. Clutch size differed significantly across the breeding season. The density of breeding pairs was 12.83 ± 0.83 p/ha, and breeding success was lower than that reported in other studies of finches and passerine birds. Predation was the cause of most nest failures. Loquat orchards seem to be the main suitable breeding habitat for the Greenfinch, and differences in some breeding biology characteristics between Algeria and European countries may be explained by climate and latitude.
