Onychoprion<\/em> anaethetus <\/em>|\u00a0Bridled tern\u00a0<\/h2>\n\n\n\n

The Bridled tern is characterised by a long forked\u00a0tail, brownish-grey coloured upper wings (hence\u00a0the name \u201cbrown dorsal\u201d in Portuguese) and a white ventral. On the front of the\u00a0head between the eyes they have a white patch in the form of a triangle. The\u00a0beak and legs are black, making them very easy to distinguish from other tern\u00a0species sighted in the Azores. Males and females are alike (i.e. they are not\u00a0sexually dimorphic). Bridled terns feed on fish which they catch by diving\u00a0down. They form colonies on rocky islands to nest\u00a0 in spring. The female lays only one egg in a\u00a0small depression in the ground. The egg is then \u00a0incubated for about 28 days. Bridled terns are distributed throughout\u00a0tropical and subtropical waters on islands of the Indian, Pacific and Atlantic\u00a0Oceans. In the Azores they are considered a very rare migrant breeding species.<\/p>\n\n\n\n
