O guarda rios malhado



"Resident, found especially along major rivers but also in other wetland areas around river deltas"

"Courtship involves dancing displays and males offering food to females. Dancing displays are gregarious and done with 3 to 12 males at one time. They noisily call to each other while holding their wings half spread and may also engage in fights by interlocking their beaks or holding their wings. Males attract females by offering food over a period of about three weeks. Pied kingfishers breed cooperatively, with non-mated birds helping raise the offspring of a mated pair. Cooperative breeding begins before eggs hatch, but more males help the breeding pair after hatching"

"Young hatch blind, pink, and helpless. Their eyes open by the ninth day and they begin to grow feathers by the fourth day. They begin diving within 2 weeks of leaving the nest"

"Characterist behaviors include the exhibition of a regular bobbing of the head or tail. They bathe by repeatedly diving into water, fly without undulation, and rarely hunt on land. Noisy chirps are uttered in flight or to mark territory during nesting. Individuals live in pairs or loosely tied families. They do not migrate"

"Vocalizations are varied and important for declaring territory and attracting mates, so C. rudis is often heard before it is seen. They are most noisy when performing courtship dances. During dances they will make a repeated “werk……werkwerkwerk” noise. Other calls include anxiety calls, a low pitch “jerp,” and threat calls, a staccato “chikerkerker...” "

Werk! werkwerkwerkwerk!!!! JERP!!! :-) Sexta é feriado!!! :-)
