Secretarybird

Sagittarius serpentarius

Photo by Stephen Krasemann (Encyclopaedia Britannica)

Common name:

Taxonomy:
Order Falconiformes
Family Sagittariidae

Range:
The secretarybird is found throughout much of sub-Saharan Africa, from Senegal and The Gambia in the west across to Ethiopia in the east, and extending southwards through the eastern African countries into South Africa. They are notably absent from the Namibe desert and from the dense tropical forests around the equator.


Size:
These birds are 90-140 cm long and have a wingspan of 180-215 cm. They weigh 2,3-4,3 kg.


Habitat:
The secretarybird prefers open savannas and grasslands with scattered trees and scrubs. They are also found in semi-arid slightly wooded areas, in Acacia thornveld and pastures. They are present from sea level up to an altitude of 3.000 m.


Diet:
These birds are opportunistic predators, taking a wide variety of prey. The majority of their diet is made up of arthropods, including grasshoppers, beetles, spiders, scorpions and wasps; and small mammals, including mice, rats, hedgehogs, hares and mongooses. Other prey include small and young birds, eggs, amphibians, freshwater crabs, lizards, small tortoises, chameleons and snakes.


Breeding:
Secretarybirds are monogamous and believed to pair for life. They can breed al year round, building a nest out of sticks, creating a large platform on a flat-topped Acacia tree or other thorny bush, and lining it with dry grass and other materials. There the female lays 1-3 chalky-white eggs with reddish-brown streaks. The eggs are incubated by both parents for 42-46 days and. The chicks are fed by both parents and typically only 2 chicks survive. The chicks fledge 64-106 days after hatching but only become fully independent 2-3 months later.


Conservation:
IUCN status - VU (Vulnerable)
Although this species has an extremely large breeding range, the global population of 10.000-100.000 individuals seems to be undergoing a rapid decline in various parts of the range. Although the species may benefit from deforestation, such positive effects may be outweighed by the negative impacts of spreading cultivation and urbanisation. The excessive burning of grasslands may suppress populations of prey species, whilst the intensive grazing of livestock is also probably degrading otherwise suitable habitat. Other threats include human disturbance, illegal capture and trade, direct hunting and indiscriminate poisoning.

Regent honeyeater

Xanthomyza phrygia

Photo by Roger Smith (Flickriver)

Common name:
regent honeyeater (en); melífago-regente (pt); méliphage régent (fr); mielero regente (es); warzenhonigfresser (de)


Taxonomy:
Order Passeriformes
Family Meliphagidae


Range:
This species is endemic to south-eastern Australia, mostly being found in north-eastern Victoria, along the western slopes of the Great Dividing Range, New South Wales, and the central coast of New South Wales.


Size:
These birds are 20-24 cm long and have a wingspan of 30 cm. They weigh 40-45 g.


Habitat:
The regent honeyeater is usually found within box-ironbark eucalypt associations, seeming to prefer wetter, more fertile lowland sites. It also uses riparian forests of river she-oak Casuarina cunninghamiana and wet lowland coastal forests dominated by swamp mahogany Eucalyptus robusta or spotted gum Corymbia maculata.


Diet:
They mostly feed on nectar and other plant sugars. They can also feed on insects and spiders, as well as native and cultivated fruits. Nectar is taken mainly from a variety of eucalypt species, especially mugga ironbark, yellow box, white box and yellow gum, and often from mistletoes like the needle-leaf mistletoe and the box mistletoe Amyema miquelii, but also from other plants, both native (Acacia, Banksia and Grevillea) and introduced (Fuchsia and Prunus).


Breeding:
The regent honeyeater breeds in May-March, with a peak in September-November, nesting in individual pairs or, sometimes, in loose colonies. The cup-shaped nests are generally composed of strips of bark and dry grass bound with spider web, usually placed toward the end of large, usually horizontal branches on the crown of an eucalypt up to 20 m above the ground. There the female lays 2-3 pinkish to reddish-buff eggs, which she incubates alone for 12-15 days. The chicks are fed by both parents and fledge 13-17 days after hatching, but remain dependent on their parents for another 3-4 weeks.

Conservation:

IUCN status - EN (Endangered)
This species has a small and fragmented breeding range, and the global population size is estimated at just 1.500 individuals. About 75% of its habitat has been cleared for agriculture and residential development, and remaining habitat is fragmented and continues to decline in quality, thus the population is suspected to be in decline, although the rate of decline has not been estimated. Habitat fragmentation has apparently advantaged more aggressive honeyeaters, particularly the noisy miner Manorina melanocephala, which may be excluding regent honeyeater from some areas.
