Abstract The Punjab urial (Ovis vignei punjabiensis) is a globally threatened wild sheep species. In Pakistan the species is legally protected and bred in captivity to release into natural habitats to reinforce wild populations. Vigilance and feeding are critical to survival, though the degree to which captive-bred animals exhibit these behaviours post-release has rarely been investigated. We monitored the daily behaviours of five adult urial after release and classifying behaviours from 0600 hrs to 1800 hrs, replicating each one-hour period twice and recording four observations of each animal per hour. At the herd level, vigilance and feeding behaviours were exhibited equally. Males and females invested equal time in feeding, males were more vigilant (p = 0.001) and more aggressive (p = 0.010), and females were more restful (p = 0.019) or engaged in grooming (p = 0.044) or locomotion (p = 0.002). Females spent more time feeding than being vigilant (p = 0.002). Males maintained high levels of vigilance throughout the day. Patterns of resting 1300 hrs to 1500 hrs and feeding in early morning and late afternoon were common for both sexes. Behaviours classified as ‘other’ were exhibited equally between sexes. Our results reveal positive indications of captive-bred urial balancing threat detection and energy acquisition post-release and exhibiting natural behaviours and activity patterns. We encourage assessment of survivorship to evaluate long-term effectiveness of captive breeding and release as a candidate restoration programme. Resumo O Punjab urial (Ovis vignei punjabiensis) é uma espécie de ovelha selvagem ameaçada globalmente. No Paquistão, a espécie é legalmente protegida e criada em cativeiro para ser liberada em habitats para reforçar as populações selvagens. Vigilância e alimentação são essenciais para a sobrevivência, embora o grau de comportamento que os animais criados em cativeiro apresenta raramente tenha sido estudado. Cinco uriais adultos foram monitorados diariamente, após a liberação os comportamentos foram classificados das 6 h às 18 h, replicando cada período de uma hora por duas vezes e registrando quatro observações de cada animal por hora. Em nível do rebanho, os comportamentos de vigilância e alimentação foram exibidos igualmente. Machos e fêmeas investiam tempo igual na alimentação, enquanto os machos eram mais vigilantes (p = 0,001) e mais agressivos (p = 0,010), as fêmeas eram mais repousantes (p = 0,019) ou mais engajadas no assei
