The numbers of Gull-billed Tern have remained over ten birds at the Dhahran Waste Water Lake and Cricket Field over the last month. This species is and extremely rare breeding migrant, common passage migrant and common winter visitor. They occur on passage from February to March and again from August to November where they mainly favour coastal sites, including bays, mudflats and brackish lagoons but also occur at inland sites, such as fish farms, wastewater lagoons and rubbish dumps. The Dhahran Waste Water Lake is a favoured place for them and they can be seen there almost every day. When they have feed enough on the lake they move to the nearby Cricket and football fields to rest.
