Nesting is a common phenomenon related to the birds’ reproductive behavior. Nests play a pivotal role in various growth stages of birds, including breeding, defense, environmental factors, shelter, and conservation. The relation between a bird and plant species is considered to be the central aspect of wildlife and biodiversity , which makes the nesting behavior a vital factor when investigating the life of birds. This study was conducted to know the trees used for nesting by avifauna species of Sheikh Badin National Park. The current study was conducted at Sheikh Badin National Park from October 2018 to September 2019 . Most birds’ breeding was observed from May to August. The dominant tree and shrub species include Ziziphus jujuba, Ziziphus mauritiana, Acacia Nilotica, Cortaderia selloana, and Sheesham Olea oleaster. Thirty-nine (39) nests of 3 selected bird species, Red-vented bulbul (Pycnonotus cafer), Baya weaver (Ploceus philippinus), and Grey bush chat (Saxicola ferreus) were found in which 18 active nests were examined during the study period at different sampling sites. All the three birds’ nest were observed on Acacia Nilotica. The average highest nests height of 5.06 ± 0.43 m were observed for Red-vented bulbul. Maximum Nest n=8 of baya weaver bird observed. Grey Bush Chat successfully hatched 100%. The average incubation days for Red-vented Bulbul l12.83 ± 1.16, Baya weaver 12.71 ± 0.75, and Grey bush chat 13.25 ± 1.5 were recorded.
