Population | Female-only care (%) | Male-only care (%) | Biparental desertion (%) | Reference |
---|
Sweden (N = 140 nests) | 48 | 18 | 34 | [29] |
Germany (N = 89 nests) | 65 | 7 | 28 | [60] |
Austria (N = 107 nests) | 54 | 14 | 32 | [60] |
Hungary (N = 291 nests) | 49 | 11 | 40 | [61] |
- In all populations a single penduline tit (either the male or the female) cares for the eggs and chicks. Biparental care is extremely rare [59], and it was not found in any of these studies. Note the high frequency of biparental desertion in all populations.
