Distinctive characters

The male in a suit has a dark brown back, the upper part of the wings with an extended white bar, the head, the chest and the hips reddish brown. The beak is blackish with black apex and lyrid of the blue celestial eye. The white undertail is usually very evident in both flying and posed subjects. The females are very similar to the adult males in dress with the color difference of the head, chest and hips (which also have a hint of broader darker stripes) which are brown (without reddish shades) and lyrid is dark. The males in eclipse dress resemble the females but retain a blue celestial lyrid. Juveniles are almost indistinguishable from females. (source: www.ornitologiaveneziana.eu)

Biology

It is a gregarious species throughout the year. It frequents shallow waters rich in emerged marsh vegetation. Due to these habits of being often hidden among the vegetation, it is not always easy to identify it. Easier to see it and recognize it when it is flying. It feeds on looking for food underwater and performs the fly after a short run-up on the water.
