Measures of Breeding Activity

Out of 18 nests studied, two clutches were predated by squirrels. In a third, one adult was killed by a Shikra (Accipiter badius), and the mate then abandoned the nest. Three eggs from different clutches failed to hatch and were discarded. Of the remaining 37 eggs that hatched, 28 fledged (>50% breeding success). The others died in the first 3 days of the nesting period (14).

Life Span and Survivorship


Disease and Body Parasites

Body Parasites

All 25 birds examined in a study were found to possess haematozoan blood parasites (18).

Causes of Mortality


Predation by Shikra (Accipiter badius) and attempted predation by Brown Boobook (Ninox scutulata) are the primary recorded sources of actual or potential mortality (14).

Direct Human Impacts

Also known to lose nests to woodcutters on account of its habit of nesting relatively low (14, 2). Birds also suffer from window collisions in urban areas (AK), and this is a likely source of mortality.

Population Spatial Metrics

Unknown other than measures of nest separation (see Breeding).

Population Status

No published information.

Population Regulation
