Taxonomy:
Order Passeriformes
Family Troglodytidae

Range:
This species is mostly found in western North America, breeding locally from southern British Columbia, Nebraska, southern Ontario, and southwestern Pennsylvania south to Mexico, Arkansas and the northern Gulf States.

Size:
The Bewick's wren in 12-14 cm long and has a wingspan of 16-17 cm. They weigh 8-12 g.

Habitat:
This species is mostly found in thickets, underbrush, gardens, but also in many brushy or wooded habitats at lower elevations, including undergrowth in woods of oak and pine, streamside groves, chaparral, desert washes and suburban areas.

Diet:
Bewick's wrens mostly forage in the trees, but also on the ground, taking a wide variety of insects, including beetles, ants, wasps, hemipterans, caterpillars, grasshoppers, and many others. They also eat many spiders, and occasionally some berries and seeds.

Breeding:
These birds breed in April-July. They nest in a cup made of sticks, leaves, moss, spider egg cases, feathers, and hair, often lined with snake skin. The nest cup is usually placed in a cavity or on a shelf, although they can also use nest boxes. There the female lays 3-8 white eggs with brown and grey blotches, which she incubates alone for 14 days. Both parents feed the chicks which fledge 14 days after hatching. Each pair produces 2 broods per season.

Marsh wren

Cistothorus palustris

Photo by Christopher Dodds (Nature Photography Blog)

Common name:
marsh wren (en); carriça-dos-paúis (pt); troglodyte des marais (fr); ratona de los estuarios (es); sumpfzaunkönig (de)

Taxonomy:
Order Passeriformes
Family Troglodytidae

Range:
This North American species is found breeding west from the Atlantic coast to Nebraska and north from southern Illinois to southern Canada. In the western United States this species is a year round resident and there are also breeding and resident populations along the coasts of the southern Atlantic and Gulf states. The wintering range extends south from the southwestern states of New Mexico, Arizona and Texas and into Mexico. Florida is also a wintering ground for the marsh wren.

Size:
The marsh wren is 10-14 cm long and weighs 9-14 g.

Habitat:
Marsh wrens use a variety of wetland habitats, showing some preference for cattail and bulbrush dominated vegetation. They occurs in salt and brackish marshes in addition to freshwater sites. The winter habitat is similar to that of the breeding range.

Diet:
These birds eat various invertebrates, especially insects like bees, ants, wasps, beetles, and moths, as well as spiders and aquatic invertebrates in freshwater marshes.

Breeding:
Marsh wrens are polygynous, with males mating with several females. The male builds several domed nests using grasses and sedges, before the females arrive in his territory. Each female uses one nest, laying 3-10 brown eggs with dark spots, which she incubates alone for 12-14 days. The chicks are brooded by the female alone, but males will sometimes feed older young. The young fledge 13-15 days after hatching.

Conservation:
IUCN status - LC (Least Concern)
This species has a very large breeding range and a global population of 8 million individuals. Degradation and destruction of marshes and other wetland habitats is the main threat affecting this species, both during the breeding season and in winter. This population is slowly declining in the eastern portion of their range, but increasing in the western parts due an increase in the extent of favourable habitat.

Size:
The riverside wren in 13-14 cm long and a wingspan of 26-30 cm. They weigh 18-22 g.

Habitat:
They are found in tropical and sub-tropical moist lowland forests, particularly along rivers and creeks. They are also found in densely forested gorges and along the edges of swamp forests. this species occurs from sea level up to an altitude of 1.200 m.

Diet:
The riverside wren feeds on a variety o invertebrates, including spiders, ear-worms, beetles and roaches. They often follow army ants in order to steal their prey.

Breeding:
