Breeding:
They breed in April-July. Male and female both contribute to nest construction, excavating a hole in a rotting tree trunk. There the female lays 5-8 white eggs, which are incubated by both parents for 17-19 days. The chicks are fed by both parents and fledge 21-27 days after hatching. Each pair only raises a single clutch each year.
Conservation:
IUCN status - LC (Least Concern)
The green woodpeckers has a very large breeding range and a global population estimated at 2-5 million individuals. The population trend is stable and there is no evidence for any significant threats.

Habitat:
Fork-tailed flycatchers are found in a wide variety of habitats including pastures, open savannas and cerrado, and riparian forests. They are also open residential areas with scattered trees.
Diet:
These birds mostly hunt insects in flight, but will also eat berries and small fruits during winter if insects become scarce.
Breeding:
Fork-tailed flycatchers breed in September-December. Both sexes build the nest, an open cup made of twigs placed in a small tree 2-6 m above the ground. The female lays 1-3 eggs which are incubated by both parents for 13-16 days. The chicks are fed by both parents and fledge 15 days after hatching.
Conservation:
IUCN status - LC (Least Concern)
This species has a very large breeding range and has a global population estimated at 5-50 million individuals. The population is suspected to be stable owing to its nomadic nature and ability to thrive in a wide range of open habitats.

Family Nectarinidae


Range:
This Asian species is found from the western Arabian Peninsula, through Iran, Afghanistan, Pakistan, India and Sri Lanka, and further east to Bangladesh, Myanmar and Indochina.


Size:
They are 9-10 cm long and weigh 4-5 g.


Habitat:
The purple sunbird inhabits woodlands and bushy terrain in arid areas as well as trees and scrub near cultivated lands or gardens, tamarisk tracts along rivers, thorn shrubs and dry forests. They are found from sea level up to an altitude of 2.400 m.

Diet:
They mainly feed on the nectar and fruit juices of various plants including Acacia, Hibiscus, Prosopis, Cordia, Albizzia, Convolvulus, Aloe, Bougainvillea, Citrus, Tecoma, Calotropis, Eucalyptus, Melia and Phoenix. Small insects and spiders are also taken during the chick rearing period.

Breeding:
Purple sunbirds breed in November-April. The nest is built by the female, consisting of a pouch made of cobwebs, thin strips of vegetation, lichens and bark with an entrance hole on the side that is often shaded by a overhanging projection. There the female lays 2-3 eggs which she incubates alone for 15-17 days. The chicks are fed insects and spiders by both parents and fledge 14-18 days after hatching.


Conservation:
IUCN status - LC (Least Concern)
This species has a very large breeding range and, although the global population size has not been quantified, this species is described as common throughout most of its range, although rare and local in Bhutan. The population is suspected to be stable in the absence of evidence for any declines or substantial threats.

Common name:
Taxonomy:
Order Cuculiformes
Family Cuculidae
Range:
This species occurs throughout much of sub-Saharan Africa, excluding extremely arid areas. They are found from Senegal, across Mali and Nigeria and into Sudan and Ethiopia, and south all the way to South Africa. This species is also present in the São Tomé and Príncipe archipelago.
Size:
The African emerald cuckoo is 22 cm long and weighs 35 g.
Habitat:
It generally prefers evergreen and riparian forest, dense woodland and moist savanna, occasionally moving into well-wooded suburbs.
Diet:
African emerald cuckoos do most of their foraging in the middle and upper forest canopy. They mostly eat caterpillars and grasshoppers, supplemented with adult Acraea butterflies and fruits such as the wild peach Kiggeleria africana.
Breeding:
They are promiscuous, territorial brood parasites. Each male defends a display territory and mates with multiple females, which then lay their eggs in the nests of other birds. Their hosts include the green-backed camaroptera Camaroptera brachyura, the white-starred robin Pogonocichla stellata, the yellow-throated woodland-warbler Phylloscopus ruficapilla and the black-throated wattle-eye Platysteira peltata. They breed in October-January and each female lays a single egg in each host nest, after destroying one host egg, for a total of about 20 eggs over the whole breeding season. The eggs are incubated by the hosts for about 16 days. The chick kicks out any of the host's eggs or nestlings at about 2 days of age, and fledges about 22 days after hatching.
Conservation:
IUCN status - LC (Least Concern)
The African emerald cuckoo has an extremely large breeding range and is reported to be fairly common. Despite ongoing destruction of riparian and lowland forest across their range, the population is suspected to be stable in the absence of evidence for any declines or substantial threats.
