These birds are found in mountainous areas, from the Iberian Peninsula and northwest Africa, through France and italy and Slovenia ans into the Balkans, Bulgaria and Greece. They are also found in northern and eastern Turkey, through the Caucasus and Iran and east to Turkmenistan, China, Korea and Japan. They are also found in Taiwan.

Size:
They are 15-17 cm long and have a wingspan of 30-33 cm. They 25-35 g.

Habitat:
They breed in high alpine country, usually at 1.800-3.000 m. They are mostly found in barren areas with boulders and low-growing plants. During the winter they go down to lower altitudes.

Diet:
Alpine accentors forage on the ground for insects, spiders, and other invertebrates. During the winter they mostly eat seeds and fruits.

Breeding:
They have a polygynandrous breeding systems with several males and females having overlapping home ranges. Males will mate with several females and females mate with several males. Within each nest there are chicks from different fathers and the males will provide food to chicks at several nests within the group, depending on whether they have mated with the female of that nest or not. They breed in May-July. The nest is a cup-shaped nest of moss, grass stalks, and fine roots in holes and rocky clefts on the ground. The female lays 4-5 pale blue eggs which are incubated by both sexes for 13-15 days. The young fledge 16 days after hatching.

Conservation:
IUCN status - LC (Least Concern)
The alpine accentor has a very large breeding range and a population estimated at 500.000-2.000.000 individuals. The population is believed to be stable, as there are no evidence for any declines or substantial threats.

Common name:

Taxonomy:
Order Passeriformes
Family Pycnonotidae

Range:
These birds are found throughout Africa, with the exception of the Sahara desert, and into the Middle East, through India and all te way to southern China and south-east Asia. They are also found in the south-east corner of Australia.

Size:
Common bulbuls are 18-19 cm long and have a wingspan of 26-30 cm. They weigh up to 50 g.

Habitat:
It is found in woodland, coastal bush, forest edges, riverine bush, montane scrub and in mixed farming habitats. It is also found in exotic thickets, gardens and parks.

Diet:
They mainly eat fruits and berries, and some shoots and buds. Sometimes also nectar, insects and spiders.

Breeding:
The common bulbul breeding season varies along their range, but mostly in May-December. The nest is a fairly rigid, thick walled cup, usually situated inside the leafy foliage of a small tree or shrub. the female lays 2-3 eggs which are incubated for 12-14 days. The chicks fledge 12-14 days after hatching. Each pair may procude 2 or more broods per year.

Conservation:
IUCN status - LC (Least Concern)
The global population size has not been quantified, but the species is described as common to abundant over its extremely large breeding range. The population in Liberia is estimated at 3 million individuals and in southern Mozambique, the population is estimated at 5-10 million individuals. However, these countries cover only a small percentage of the species's total range so the global population is likely much higher. The population is suspected to be increasing owing to ongoing habitat modification and degradation, which favours the species.

Common name:

Taxonomy:
Order Apodiformes
Family Apodidae

Range:
They breed in Asia, from central and south-eastern Siberia and Mongolia, east to coastal Russia, northern Japan and sorth-eastern China. A separate population breeds in south-western China and the Himalayas in northern India and Pakistan. The wintering areas mostly lay in eastern Australia, with some birds also staying in New Zealand, Papua New-Guinea and south-east Asia.

Size:
The white-throated needletail is 20-22 cm long and has a wingspan of 43-48 cm. They weigh 100-140 g.

Habitat:
This species breeds in wooded lowlands and sparsely vegetated hills, as well as mountains covered with coniferous forests. They forage aerially, at heights up to cloud level, above a wide variety of habitats ranging from heavily treed forests to open habitats, such as farmland, heathland or mudflats, though they sometimes forage much closer to the ground in open habitats. They sometimes forage over recently disturbed areas, such as forest that has been recently cleared or burnt, or above paddocks as they are being ploughed or slashed. They often forage in areas of updraughts, such as ridges, cliffs or sand-dunes or in the smoke of bush fires, or in whirlwinds.

Diet:
They mostly take insects and spiders in flight. Among their insect prey are beetles, cicadas, wasps, flies, moths, locusts, ants and termites.

Breeding:
White-throated needletails breed in May-June. Both parents take equal part in the breeding process. The nest is placed in a vertical hollow in a tall coniferous tree or on a vertical rock-face, either comprising a small bracket or half-cup of thin twigs and straw cemented together by the bird's saliva and glued to the side of the hollow or rock, or a shallow scrape among debris accumulated at the bottom of a tree hollow. The female lays 2-7 eggs, which are incubated by both sexes for 21 days. The chicks fledge after 40–42 days.

Conservation:
IUCN status - LC (Least Concern)
This species has an extremely large breeding range. The population is suspected to be stable in the absence of evidence for any declines or substantial threats.

This South American species in only found in Chile and Argentina. In Chile they are found from Magallanes north to Atacama, while in Argentina they occur from Santa Cruz north to Mendoza.

Size:
The rufous-tailed plantcutter is 18-20 cm long and weighs 38-52 g.

Habitat:
They are found from sea level up to an altitude of 2.700 m, in open forests and thorny scrubland, as well as in farmland, orchards and gardens.

Diet:
This species is mostly herbivorous, showing a preference for leaves, shoots and buds. they will occasionally also take fruits and insects.

Breeding:
The rufous-tailed pantcutter has two distinct breeding seasons, in October-November and in December-January. The nest is built by both sexes, consisting of a loosely built cup made from dry twigs, padded with root fibers, and usually placed 1-3 m above the ground in a thick thorny scrub. the female lays 2-4 blue-green eggs with dark spots. The female incubates the eggs alone, but the incubation period is not known. The chicks are fed by both parents, eating only insects

Conservation:
IUCN status - LC (Least Concern)
Although the species is described as uncommon, they have a relatively large breeding range. There is no evidence for any declines or substantial threats, and the species is known to use secondary forests, agricultural areas and even gardens, so it appears to be relatively tolerant of disturbance. Owing to its habit of eating the young leaves of cereal crops and causing damage to orchards, it is considered an agricultural pest in parts of its range. It is not considered threatened at present.

Yellow-billed loon

Gavia adamsii

Photo by Fredrik Salin (Internet Bird Collection)

Common name:

Taxonomy:
Order Gaviiformes
Family Gaviidae

Range:
They breed in the Arctic, in Russia, Alaska and Canada. They mostly winter at sea, along the coasts of Norway, western Canada and northern Japan, but also sometimes in inland lakes.

Size:
This large loon is 76-97 cm long and has a wingspan of 135-160 cm. They weigh 4-6,5 kg.

Habitat:
The yellow-billed loon mostly breeds on freshwater pools, lakes or rivers in the Arctic tundra, showing a preference for deep, clear lakes with stony or sandy substrates where water levels do not fluctuate. they prefer lakes where the water does not completely freeze, which have dependable supplies of fish and which have highly convoluted shorelines and aquatic vegetation providing habitats for fish and sites for nesting and brood rearing. Outside the breeding season the species inhabits inshore waters, fjords with muddy substrates and inlets along sheltered coasts, generally avoiding ice-covered waters.

Diet:
They mostly eat fish, namely Cottidae, Microgadus proximus and Gadus morhua, as well as crustaceans, molluscs and marine annelids.

Breeding:
Yellow billed loons start nesting in June-July. Both sexes build the nest, a small depression in a mound of plant matter or turf, constructed on dry land near the water edge. The female lays 2 eggs which are incubated by both parents for 27-28 days. Chicks are dry and active within hours of hatching; brooding by both parents occurs in nest for about 3 days, then little on-shore brooding after about 9 days. In some areas, chicks 9-16 days old observed riding on parents back. Adults forage to feed young for up to 45 days.

Conservation:
IUCN status - NT (Near-Threatened)
Although they have a very large breeding range, the population is currently estimated at just 16.000-32.000 individuals, and is suspected to be undergoing a moderately rapid population decline owing to unsustainable subsistence harvest. This species is also vulnerable to oil spills in both its breeding and wintering ranges, and may be threatened by oil development activities on its Alaskan breeding grounds. These threats are exacerbated by a low reproductive rate and very specific breeding habitat requirements.

Common name:

Taxonomy:
Order Passeriformes
Family Regulidae

Range:
The firecrest breeds mostly in Europe, from southern England, France, Spain and Portugal, east to Belarus, north-western Ukraine and Greece, and north to the Baltic and southern Latvia. There are isolated populations in the east, in Abkhazia, Crimea, Turkey, and in the western Mediterranean, in the Balearic islands, Morocco, Algeria and Tunisia. Southern birds are largely resident, unlike the northern and eastern populations which migrate to the Mediterranean basin in winter.

Size:
These tinny birds are 9cm long and have a wingspan of 13-16 cm. they weigh 4-7 g.

Habitat:
It breeds in lowland broadleaf forest, preferring cork oak and alder where available, otherwise beech and holly. It also uses mixed broadleaf and conifer woodland, and stands of spruce, European silver fir, cedar and pines, often with undergrowth of juniper, ivy and wild rose. In drier Mediterranean habitats it is found in conifers, evergreen oaks, and mixed woodlands up to 2.800 m.

Diet:
They are almost exclusively insectivorous, preying on small arthropods with soft cuticles, such as springtails, aphids and spiders. They also feed on the cocoons and eggs of spiders and insects, and occasionally take pollen. They can also hover to catch flying insects.

Breeding:
Firecrests start breeding in April-May. The nest is constructed by the female alone, although the male will accompany the female while she builds the nest over a period of a few days to three weeks. The nest is a closed cup built in three layers with a small entrance hole near its top. The nest's outer layer is made from moss, small twigs, cobwebs and lichen, the spider webs also being used to attach the nest to the thin branches that support it. The middle layer is moss, and this is lined with feathers and hair. The female lays 7-12 pink eggs with very indistinct reddish markings at the broad end. The female incubates the eggs alone for 14-17 days and broods the chicks, which fledge 8-10 days later. Both parents feed the chicks and fledged young.

Conservation:
IUCN status - LC (Least Concern)
The global population is estimated at 3.300.000-6.700.000 individuals. This species has a very large breeding range and the population trend is believed to be stable, so it is not threatened.

(Photo from Flickr)

Common name:

Taxonomy:
Order Passeriformes
Family Tyrannidae

Range:
These birds breed in the south of the United States in Colorado, New Mexico, Nebraska, Missouri, Arkansas, Louisiana and Texas, and in northern Mexico. They winter in Central America, from southern Mexico down to Costa Rica

Size:
The scissor-tailed flycatcher shows strong sexual dimorphism in terms of tail length. Because of this females are 25-26 cm long while males are 38-39 cm long. They have a wingspan of 38 cm and weigh 36-56 g.

Habitat:
They mostly breed in open grasslands with occasional trees and scrubs, but also in towns and agricultural areas. During the winter they are typically found either in open grasslands or along the edges of tropical forests.

Diet:
They are insectivorous, mostly taking grasshoppers, crickets and beetles. they may occasionally take berries in winter.

Breeding:
Scissor-tailed flycatchers breed in March-August. The nest is an open cup of plant stems and string, lined with finer plant materials, generally placed in small isolated trees or large shrubs. The female lays 3-6 creamy eggs with brown spots, which she incubates alone for 13-16 days. the chicks are fed by both parents until fledging, which takes place 14-17 days after hatching.

Conservation:
IUCN status - LC (Least Concern)
The population increased its range in the 19th and 20th century probably as the result of clearing forests and the planting of ornamental trees. It is now believed to be declining in parts of its very large range, but the population is still estimated at 7,9 million. The species is not threatened at present.

Grus grus

Photo by Tarique Sani (Flickr)

Common name:

Taxonomy:
Order Gruiformes
Family Gruidae

Range:
They breed in northern Eurasia, from Scandinavia, Germany and Poland in the west, all the way to eastern Siberia, Mongolia and northern China. There are also some isolated breeding populations further south, in Turkey. They winter in the Iberian Peninsula and along the Mediterranean coast of North Africa, along the Nile basin, in the Middle East, northern India and in southern China.

Size:
These large birds are 110-130 cm long and have a wingspan of 220-245 cm. They weigh 5-7 kg.

Habitat:
During the breeding season this species utilizes a wide variety of shallow wetlands, including high altitude, treeless moors or bogs, usually with some standing water, and swampy forest clearings, reedy marshes and rice paddies. In Central Asia the species may use drier forested areas including pine or mixed birch/pine woodland. They winter in floodlands, swampy meadows, shallow sheltered bays, rice paddies, pastures and savanna-like areas such as the open Holm and cork oak woodlands in the Iberian Peninsula.

Diet:
The common crane is omnivorous. They forage on a wide range of roots, rhizomes, tubers, herbs, pondweeds, berries, cereal grains, peas, olives, acorns and nuts. they hunt various animals including beetles, flies, larval Lepidoptera, snails, earthworms, millipedes, spiders, frogs, lizards, snakes, small mammals, fish and occasionally the eggs and young of small birds.

Breeding:
They start nesting in March-April. The nest is a mound of wetland vegetation, generally placed in or near water in an inaccessible, undisturbed bog, heath, marsh, mire or sedge meadow. The female lays 2 greenish-brown eggs with brown spots. The eggs are incubated by both parents for 29-31 days. The nidifugous chicks leave the nest within 30 h of hatching, but the parents will stay with them, brooding and offering food whenever necessary. the chicks fledge 65-70 days after hatching, but often remain with the parents even on migration and in the wintering areas.

Conservation:
IUCN status - LC (Least Concern)
Both the breeding and non-breeding habitats are threatened by habitat loss and degradation through dam construction, urbanization and agricultural intensification. Increased nest disturbance and nest predation are also a problem in some parts of their range. Pesticide poisoning, collisions with power lines and hunting are threats during migration and winter. Despite these, overall the population trend is uncertain, as some populations are decreasing, while others are increasing, stable or have unknown trends. With a population of 360.000-370.000 individuals and a very large breeding range, the species is not considered threatened at present.
