Common name:
hawfinch (en); bico-grossudo (pt); gros-bec casse-noyaux (fr); picogordo común (es); kernbeißer (de)

Taxonomy:
Order Passeriformes
Family Fringillidae

Range:
This species is found throughout most of Europe, from the Iberian Peninsula north to Britain and southern Scandinavia and east into Turkey and Russia, along the Caucasus and southern Russia into northern Kazakhstan, northern Mongolia and north-eastern China. There are also population in Iran, between Uzbekistan and western China, and in northern Africa from Morocco to Tunisia. The populations in Europe are mostly resident, but the most Asian population migrate to winter around the Mediterranean, and in south-eastern China, Korea and Japan.

Size:
These birds are 16,5-18 cm long and have a wingspan of 29-33 cm. They weigh 48-62 g.

Habitat:
The hawfinch is mostly found in temperate forests, mainly oak and other deciduous trees but also mixed and coniferous forests. They also use rural gardens as well as urban parks and gardens.

Diet:
They feed mainly on seeds, being able to crack open seeds and large as cherry pits and almonds with their strong beak. They also take buds, shoots of various tree and scrubs. During the breeding season also caterpillars.

Breeding:
Hawfinches breed in March-July. They can either nest in individual pairs or often in small colonies. Each nest is a bulky structure made of dry twigs, with an inner cup made of roots grasses, twigs, dry moss, and lichens. It is usually placed in a large tree. The female lays 4-6 whitish eggs with dark brown blotches, which she incubates alone for 11-14 days while the male brings her food. The chicks fledge 10-14 days after hatching. Each pair usually raises a single clutch per year, but in very favourable years they may raise a second clutch.

Conservation:
IUCN status - LC (Least Concern)
This species has an extremely large breeding range and a global population estimated at 14,7-50,4 million individuals. The population is suspected to be stable in the absence of evidence for any declines or substantial threats and data for part of Europe show a stable trend over the last 3 decades.

Common name:
sacred kingfisher (en); guarda-rios-sagrado (pt); martin-chasseur sacré (fr); alción sagrado (es); götzenliest (de)

Taxonomy:
Order Coraciiformes
Family Alcedinidae

Range:
This species breeds throughout most of mainland Australia, as well as in New Zealand and in western Melanesia as fas east as Fiji. The populations in southern Australia migrate north to winter in Papua-New Guinea and throughout Indonesia.

Size:
These birds are19-23 cm long and weigh 30-60 g.

Habitat:
The sacred kingfisher is mosty found in tropical forests, such as in Eucalyptus woodlands and rainforests, but also in other types of open forest, Acacia scrublands, Melaleuca swamps, grasslands with scattered trees, mangroves, coastal lakes and lagoons, both sandy and rocky coastlines, rural gardens, arable land, plantations and urban parks.

Diet:
They hunt by pouncing on their prey from a perch, taking a wide range of prey including
a wide range of insects and other invertebrates, such as spiders, centipedes, worms and crustaceans, but also small vertebrates including fishes, tadpoles and frogs, lizards, snakes, birds and mice.


Breeding:
Sacred kingfishers are monogamous and pair bonds possibly last several years. They breed in September-March and nest in a tree hollow or in a tunnel excavated by both sexes in a bank, cliff or even a termite mound. the female lays 3-7 eggs which are incubated by both parents for 16-21 days. The chicks are fed by both parents and fledge 24-29 days after hatching, but continue to receive food from the parents for another 7-10 days. Each pair usually raises 2 broods per season, but they may not breed during drought years.

Conservation:
IUCN status - LC (Least Concern)
This species has a very large breeding range and although there are no reliable population estimated the population is suspected to be increasing owing to opening up of forest areas and road building which has provided an increase in suitable nesting sites.

Seychelles magpie-robin

Copsychus sechellarum

Photo by Philip Perry (Internet Bird Collection)

Common name:
Seychelles magpie-robin (en); pisco-das-Seychelles (pt); shama de Seychelles (fr); shama de Seychelles (es); Seychellendajal (de)

Taxonomy:
Order Passeriformes
Family Muscicapidae

Range:
This species is endemic to the Seychelles archipelago and was originally present in at least 8 islands, but by the 1960s it became restricted to the island of Frégate. Since then the species has been reintroduced to the islands of Aride, Cousin, Cousine and Denis.

Size:
These birds are 18-25 cm long and weigh 60-80 g.

Habitat:
The Seychelles magpie-robin was originally found in mature coastal rainforest but today uses mature woodlands on central plateaus, plantations and vegetable gardens. They prefer areas with a tall, closed canopy with sparse understorey and ground vegetation but abundant leaf litter.

Diet:
They forage on the ground, among the forest leaf litter, mainly taking soil invertebrates, particularly cockroaches but also other insects, worms, centipedes and millipedes. They also take fruits, fish dropped by tree-nesting terns, skinks and geckos, eggs and human food scraps.

Breeding:
These birds can breed all year round, especially in periods with higher rainfall. The female builds the nest alone, consisting of a simple cup made of dry grasses and coconut fibres, placed in the crown of a coconut tree or on a hole in a large tree. The female lays a single eggs which she incubates alone for 17-22 days while the male guards the nest from predators. The chick is fed by both parents and fledges 18-20 days after hatching, becoming fully independent about 11 weeks later. They reach sexual maturity at 1 years of age and each pair raises a single chick per year.

Conservation:
IUCN status - EN (Endangered)
This species has an extremely small breeding range and the global population is estimated at just 120 individuals. By 1965 only 12-15 Seychelles magpie-robins survived on the island of Frégate having declined mainly due to predation by introduced cats and, to a lesser extent, predation by introduced rats and habitat destruction. Cats were eradicated from Frégate in the 1980s and since the 1990s individuals have been translocated to several predator-free islands, leading to a small recovery in numbers. Further threats include changes in agricultural practices and introduction of exotic plants, as well as future sea level rise.
