Abstract:

Rallids are good biological models to monitor anthropogenic changes to wetlands. The distribution of the Rallidae was mapped up during a survey of all major wetlands across Algeria and nest site selection, phenology, and breeding parameters of the Purple Swamp-Hen Porphyrio porphyrio were monitored at two distinct sites under contrasting conditions. Data were collected at Boussedra, an unprotected freshwater marsh during the years 2005 and 2008, and at Lake Tonga, a protected freshwater marsh during 2009. The onset of egg-laying was found to occur earlier (mid-February) than was recorded previously (end-March). There was much variation in the egg laying patterns and in the clutch sizes which dropped significantly from 5.8 ± 0.9 (Boussedra 2009) to 3.4 ± 0.9 (Boussedra 2008) and 3.9 ± 1.0 (Tonga 2009). This study, the first investigation of the ecology and conservation of the Purple Swamp-Hen in North Africa, suggests a decline in breeding success associated with steady habitat loss and ineffective enforcement of legislation.

Abstract:

The Purple Swamphen Porphyrio porphyrio is a common rail that previously was little investigated in North Africa. From 2011 to 2013, its breeding ecology was studied at two natural wetlands in north-east Algeria, namely Garaet Hadj Tahar and Garaet Messaoussa. Numbers of Purple Swamphens at both localities peaked in late April and early May. Egg-laying started in early March, whereas hatching started in late March. Peak egg-laying took place in late March and early April, and peak hatching from mid-April to early May. There were significant differences in the size and weight of eggs between years and localities. The mean clutch size was 2.75 ± 0.70 eggs and it was not significantly different between localities and years. Mean hatching success was 51% and it was positively correlated to nest depth only at Garaet Hadj Tahar. Most nests were built in dense tufts of Typha angustifolia and Phragmites australis. The main nesting materials were Phragmites australis and Scirpus maritimus.
