9-4-2016 GANDIA, VALENCIA - WESTERN YELLOW WAGTAIL (Motacilla flava)

Outside of the breeding season, Western yellow wagtails are gregarious and often spend time in flocks. They also gather in large numbers on the night roosts and migrate in flocks. Western yellow wagtails are active during the day spending their time in search of food. They forage by walking on the ground picking insects or seeds and can also search for food items walking in shallow water. They may catch insects on the wing or pick them up while flying over vegetation. Western yellow wagtails frequently wag their tail while foraging. The common call of these birds is a high-pitched 'jeet'. When flying they often produce loud 'pseet' or long 'swee-eep'.

Western yellow wagtails are monogamous. They form pairs and prefer to nest separately. They breed from April to August and are territorial during this period with each pair defending its nesting site. The nest is a shallow scrape located on or near the ground; it is made of grass and lined with animal hair. The female lays 4-6 eggs and both parents incubate them for about 11-13 days. The chicks hatch blind and helpless and are fed by both parents. They fledge between 10 and 14 days but usually remain with their parents for several weeks more.
