Abstract: Knowledge of food resource of the houbara which an
endangered species would be a important step toward the
preservation of this bird. Adequate study has not been done in this
field and therefore the food sources of the houbara during the
brooding season was studied in the central steppe of Iran. In order to
determine the density of insect in plant communities the pitfall trap
was used , positioned in five linear transects divided between plant
communities and in two repetitions. The results showed that the
among communities there was a significant difference in term of the
number beetles and ants ( p= 0.01, F2, 29= 4.66) collectively. Also
bush steppe habitat had a higher arthropoda density in comparison
with the shrub steppe habitat. Considering that most houbara nests
were found in the bush steppe habitat .It seems this habitat provides
the most available food supply for the houbara chicks.
Abstract: Asiatic Houbara ( Chlamydotis macqueenii ) is a
flagship and vulnerable species. In-situ conservation of this
threatened species demands for knowledge of its habitat selection.
The aim of this study was to determine habitat variables influencing
birds wintering and breeding selection in semi- arid central Iran.
Habitat features of the detected nest and pellet sites were compared
with paired and random plots by quantifying a number of habitat
variables. In wintering habitat use at micro scale houbara selected
sites where vegetation cover was significantly lower compard to
control sites( p< 0.001). Areas with low number of larger plant
species (p=0.03) that were not too close to a vegetation
patch(p
