It weaves its way through the reeds, soars through the branches of the Willows, grazes the surface of the water, settles on a perch from which its powerful song gushes. La Bouscarle de Cetti slips into the vegetation of ponds and the edges of rivers.
Alongside chickadees and ducks
Water in the garden brings life, brings many species of birds. Depending on the size of the body of water, we will see the aquatic birds of the basin, duck, sarcelles, fuligules, harles, wild or farmed species, swimming, resting on the banks, digging in the mud for food. Passerines regulars in the garden, tits, robin, sparrows, blackbirds, will come to quench their thirst and bathe on the shallow banks. By their side, discreet in the dense vegetation, Cetti’s Bouscarle will settle between land and water.
White eyebrow and erect tail
Red-brown feather ball, with pale chest and cheeks, the Bouscarle de Cetti (Cettia cetti) would look like a warbler by its silhouette, at a troglodyte by its behavior. The same way of sneaking through the low vegetation, of snooping, nervous and fast, with an erect tail, perpendicular to the body. It is distinguished by its long rounded tail, and his white eyebrow clearly marking his forehead. And his discretion …
Bushes, Phragmites and Reeds
La Bouscarle de Cetti look for flowing waters, ponds, ponds, bordered by abundant vegetation, diversified, where aquatic perennials, willows, viburnums, dogwoods … If it can camouflage itself in its habitat, it does not hesitate to get closer to human dwellings, parks, water gardens, canals. A stream, a river, nearby, will promote its presence, common in France throughout the year.
A powerful song
La Bouscarle de Cetti gets along more than she sees herself. If she stays difficult to observe, reddish-brown, always weaving through the dense vegetation, it is noticed by its surprisingly powerful song. Installed on a perch, she launches an explosive, rapid sentence. Then move, and start again from another perch. This song cannot be confused with any other, and will also be heard at night, shorter. In the event of an alert or concern, La Bouscarle will issue a short, high-pitched “pitt”.
A diverse menu
Insectivore, with its small thin and dark beak, the Bouscarle feeds on invertebrates, aquatic larvae, drowned insects floating on the surface of the water. However, she does not disdain a few small spiders, worms and mollusks. Even supplementing, occasionally, its menu of a few seeds, the diversification of its diet allowing it to adapt to variations in its habitat. And to carry out 2 broods per year.
Brick red eggs
In spring, males and females meet, ephemeral couples, renewed at each love parade. The nest is installed in low vegetation, built of dry herbs, leaves, garnished with feathers, silky seeds of mallets. 3 to 4 brick-red eggs are laid there, incubated for a fortnight. The little ones will take their first flight after 2 weeks, closely watched by the parents.
Mare, basin, pond, streams, favor the presence of many birds. Among which the Bouscarle de Cetti will gladly invite itself, especially if a diversified and abundant vegetation is offered to it. This species sedentary, occasional migrant from cold regions, seems not to be impacted by climate change and remains common in many regions of France.
