Until the discovery of nesting in 2008, this species had only been considered as wintering in Tunisia. The Tunisian breeding population resides in the Lebna Dam in the north east of the country where it forms a mixed nesting colony with other species of the family Ardeidae （（Bubulcus ibis （Bi）： 388 pairs, Ardeola ralloides （Ar）： 17 pairs, Egretta garzetta （Eg）： 27 pairs）, （Bi： 300 pairs, At： 25 pairs, Eg： 40 pairs） and （Bi： 400 pairs, Ar： 30 pairs, Eg： 10 pairs） recorded in 2008, 2009 and 2010 respectively）. All nests were constructed on Acacia horrida. Laying began in early May. The average clutch size over the three years of the study was 3.44 ± 0.73 eggs （N = 29 nests）. Hatching success was 83 % （2.86 ± 1.18 eggs hatched/nest） and 2.65 ± 1.17 hatchlings/nest survived until the age of 10 to 12 days. Egg mortality was 17% during the incubation phase and chick mortality was 7.2%. No interannual variation was detected in these parameters.展开更多
This paper provides the information on nesting biology of 20 bird species in alpine shrub (4000-4700 m a.s.l.) or alpine meadow-wasteland habitats (4300-4700 m a.s.l.) in Lhasa region,Tibet.Of these species,three are ...This paper provides the information on nesting biology of 20 bird species in alpine shrub (4000-4700 m a.s.l.) or alpine meadow-wasteland habitats (4300-4700 m a.s.l.) in Lhasa region,Tibet.Of these species,three are endemic to the Tibetan plateau and 17 widespread in altitudes.The data on these taxa are all new to the high-altitude environments,especially the upper limit of their breeding distribution.A few species are firstly reported with respect to nesting information in the world.The study will contribute our knowledge for natural history of birds occurring in the harsh,extreme habitats.展开更多
