Abstract

Breeding success and juvenile survival in a reintroduced captive-bred population of Asian houbara bustards in the United Arab Emirates

Highlights

  • Reintroduction is an important conservation tool to restore populations of endangered species (Seddon et al 2012, IUCN 2013)

  • Between 2008 and 2015, a total of 84 nests from captive-bred released females were found in the western reserves of Abu Dhabi

  • Nest initiation date was positively influenced by progress of the breeding season, time (RVI = 1, β = 0.001, 95% CI = 0.0007− 0.0014) and negatively with temperature2 (RVI = 1, β = − 0.04, 95% CI = −0.05 to −0.02; Table 2)

Summary

INTRODUCTION

Reintroduction is an important conservation tool to restore populations of endangered species (Seddon et al 2012, IUCN 2013). The Asian houbara Chlamydotis macqueenii (hereafter ‘houbara’) is a medium-sized bustard species adapted to arid and semi-arid ecosystems (Hoyo et al 1996, Van Heezik & Seddon 1999, Riou & Combreau 2014). It is resident in the southern extent of its range (from the Arabian Peninsula to southern Central Asia), but migratory in most of Central Asia and parts. We provide detailed information about breeding success in a reintroduced captive-bred population of resident houbara in western Abu Dhabi reserves. Habitats in all 4 reserves are similar, each comprised of undulating sand dunes and gravel plains intermixed with flat salty areas (sabkhas) and sparse
