N2 - The Tejo estuary is a key site for wintering and migratory waterbirds both at the national and international levels. Here we report the main findings of an ongoing monitoring programme of waterbirds in the main high tide roosts of the estuary. A decade of monthly counts (between 2007 and 2016) revealed peaks in waterbird abundance occurring between August and February, with monthly averages of over 28000 birds. Overall, our data highlight the importance of this wetland during winter and autumn migration, with lower but also relevant numbers during spring migration.
