Common name:
red-backed shrike (en); picanço-de-dorso-ruivo (pt); pie-grièche écorcheur (fr); alcaudón dorsirrojo (es); neuntöter (de)

Taxonomy:
Order Passeriformes
Family Laniidae

Range:
This species breeds throughout most of Europe, with the exception of the British isles and Iceland, from the northern Iberian Peninsula to northern Sweden and Finland, and east to Russia, Kazakhstan and north-western Iran. They migrate south to winter in southern Africa, from Kenya and northern Angola down to South Africa.

Size:
These birds are 16-18 cm long and have a wingspan of 26 cm. They weigh 28-33 g.

Habitat:
The red-backed shrike breeds in a wide range of habitats, including dry scrublands, temperate grasslands, temperate and boreal forests, pastures, plantations, arable land, orchards and even within urban areas. They winter in dry savannas.

Diet:
They feed mostly on ground invertebrates and flying insects, but also small birds and mammals, lizards and frogs. Prey items are often impaled on thorns in order to build up a food supply for periods of bad weather.

Breeding:
Red-backed shrikes breed in April-July. They nest in a cup made of plant stems, roots and grass, and lined with moss and hair. The nest is placed in a thorny scrub or small tree, usually 1,5-3,5 m above the ground. There the female lays 3-6 whitish egg with light brown spots, which she incubates alone for 14-15 days. The chicks are fed by the female, while the male collects food for the family, fledging 14-16 days after hatching.

Conservation:
IUCN status - LC (Least Concern)
This species has a very large breeding range and the global population is estimated at 38-156 million individual. The population is estimated to be declining overall following a dramatic decline in the west and north-east of its breeding range from 1970 to 1990 at least. However, in Europe, trends since 1980 show that populations have undergone a moderate increase.

Pink-legged graveteiro

Acrobatornis fonsecai

(Photo from Flickr)

Common name:
pink-legged graveteiro (en); acrobata (pt); anabasitte à pattes roses (fr); graveteiro (es); plantagenschlüpfer (de)

Taxonomy:
Order Passeriformes
Family Furnariidae

Range:
This species in endemic to Brasil, only being found in south-east Bahia and north -east Minas Gerais, mostly between the rivers Jequitinhonha and das Contas.

Size:
These birds are 13-14 cm long and weigh about 14 g.

Habitat:
The pink-legged graveteiro is found in the canopy and sub-canopy of extensive shade cocoa plantations, within moist tropical forests, from sea level up to an altitude of 550 m.

Diet:
They feed on insects and other arthropods, namely beetles, termites, moths, ants, insect larvae, insect eggs and spiders.

Breeding:
Pink-legged graveteiros breed in September-October. They are monogamous and both sexes help build the nest. Both sexes help build the nests, each woven with sticks, consisting of an entrance corridor leading to a single incubation chamber that is heavily lined with leaves and moss. Each pair builds up to 5 nests within a single tree, but only one is active. The others are thought to be dummy nests, used to confuse predators and parasites, but they may also serve as places to store nest construction materials. The female lays 2-3 eggs, which are incubated by both sexes. The chicks are raised by both parents, but the is no information regarding the length of the incubation and fledgling periods.

Conservation:
IUCN status - VU (Vulnerable)
This species has a relatively small breeding range and a global population estimated at 2.500-10.000 individuals. The population is suspected to be declining rapidly due to habitat loss. Virtually all forest below 400 m has been converted to cocoa plantations or completely cleared. The system of shaded cocoa plantations has secured the survival of a continuous canopy cover in places, but there is no forest regeneration owing to weeding of the understorey. During the 1990s, falls in the price of cocoa and the introduction of a fungal disease resulted in a downturn in cocoa production. Landowners have started to sell timber from the shading forests, and to shift production from cocoa to other crop-types or livestock-grazing, increasing the pressure on the pink-legged graveteiro.

Seychelles warbler

Acrocephalus sechellensis

Common name:
Seychelles warbler (en); felosa-das-Seychelles (pt); rousserolle des Seychelles (fr); carricero de Seychelles (es); Seychellen-rohrsänger (de)

Taxonomy:
Order Passeriformes
Family Sylviidae

Range:
This species is endemic to the Seychelles archipelago. At present they are only found in the islands of Cousin, Aride, Cousine and Denis.

Size:
These birds are 14 cm long and weigh 15-17 g.

Habitat:
The Seychelles warbler is found in most tropical scrublands with large Pisonia grandis and Ficus reflexa trees.

Diet:
They feed on a variety of insects, including bugs and their eggs, beetles, bees and ants, but also spiders and, occasionally, small skins and geckos.

Breeding:
The Seychelles warbler is monogamous and mates for life. They have a cooperative breeding system, with helpers, usually the daughters from previous broods, helping defend the territory, build the nest, incubate the eggs and feed the young. They breed in June February. The female lays a single egg, which is incubated for 15 days. The chick fledges 14 days after hatching but may continue to receive food from the parents and helpers for several months.

Conservation:
IUCN status - VU (Vulnerable)
This species was an extremely small breeding range and a global population estimated at 1.700 individuals. The Seychelles warbler was originally found in several islands in the Seychelles, but human disturbance, habitat destruction and predation by introduced predator lead them to disappear in all islands except Cousin. Even in that island, the population reach an all time low of less than 30 individuals in the 1960s, but has since recovered thanks to
favourable management and conservation policies. In Cousin, management included the regeneration of Pisonia woodlands, and cessation of intensive management of coconut Cocos nucifera plantations. The islands of Aride, Denis and Cousine were also the target of habitat management and predator control, and have been populated successfully with birds from Cousin. These conservation efforts and considerable population recovery make the Seychelles warbler a great success case for nature conservation.

They forage on the ground, mainly eating seeds and green plant material. During the breeding season they also eat insects and earthworms.

Breeding:
Thekla larks breed in April-June. The female builds the nest, a small cup made of dry grasses and placed on the ground. There she lays 2-6 light brown eggs with darker blotches, which she incubates alone for 11-17 days. The chicks are fed by both parents and fledge 15-16 days after hatching.

Conservation:
IUCN status - LC (Least Concern)
This species has a very large breeding range and the global population is estimated at 9-25 million individuals. The population is declining in Spain, due to habitat loss and degradation, but is believed to be stable elsewhere.
