Tinian monarch

Monarcha takatsukasae

Photo by Desmond Allen (Internet Bird Collection)

Common name:
Tinian monarch (en); monarca-de-Tinian (pt); monarque de Tinian (fr); monarca de Tinian (es); Tinianmonarch (de)

Taxonomy:
Order Passeriformes
Family Monarchidae

Range:
This species is endemic to the island of Tinian in the Northern Mariana Islands.

Size:
These birds are 15 cm long.

Habitat:
The Tinian monarch is mostly found in limestone forests, but uses all forests available on Tinian, including secondary forests and introduced tangan-tangan Leucaena leucoephala thickets.

Diet:
They are mainly insectivorous, gleaning invertebrates such as moths, butterflies, ants, caterpillars, and several long legged insects from leaves and bark. They are also known to occasionally eat small lizards.

Breeding:
Tinian monarchs can breed all year round, but with seasonal peaks related with rainfall levels. The nest is built by both sexes, consisting of an open cup made of dry Casuarina  needles, dry leaves, grasses, vine tendrils, spider webs, and lined with feathers. It is placed at the base of a vertical branch, up to 2 m above the ground. The female lays 1-3 white eggs with reddish-brown spots, which are incubated by both parents for 15 days. The chicks fledge about 13 days after hatching, but continue to receive food from the parents for another 8 weeks.

Conservation:
IUCN status - VU (Vulnerable)
This species has a small breeding range and a global population estimated at 20.000-50.000 individuals. Following declines in the first half of the 20th century caused by deforestation, the population is now believed to be stable. However, declines of up to 50% are projected in the likely event of the brown tree-snake Boiga irregularis becoming established on Tinian. Other threats include typhoons, forests fires, forest clearance for cattle farming, military activities and tourism, and avian diseases.

Hawaii elepaio

Chasiempis sandwichensis

(Photo from Flickr)

Common name:
Hawaii elepaio (en); monarca-do-Hawai (pt); monarque d'Hawaï (fr); monarca elepaio (es); Hawaii-elepaio (de)

Taxonomy:
Order Passeriformes
Family Monarchidae

Range:
This species is endemic to the island of Hawai'i, in the Hawaian islands.

Size:
These birds are 14 cm long and weigh 12-18 g.

Habitat:
The Hawaii elepaio is found in moist tropical forests, moist scrublands and dry savannas with some differences between subspecies. The subspecies C. s. bryani occupies arid, mostly high-altitude mamane and mamane-naio woodland, whilst C. s. sandwichensis occurs in mesic habitats on western and south-western slopes, and C. s. ridgwayi is restricted to wet, eastern slopes. They are present from sea level up to an altitude of 2.900 m.

Diet:
They forage on the foliage and in the ground, taking large insects and other arthropods.

Breeding:
Hawaii elepaios breed in January-August. They are monogamous and often mate for life. The nest is built by both sexes, consisting of a finely woven cup made of a wide variety of materials including grasses, bark strips, lichens and spider webs. It is placed in a fork or on a horizontal branch, often in mamane Sophora chrysophylla trees. The female lays 2 eggs, which are incubated by both parents for 17-19 days. The chicks are fed by both parent and fledge 15-16 days after hatching, but remain in ther parental territory for up to 10 months. Each pair can raise 1-2 broods per year.

Conservation:
IUCN status - VU (Vulnerable)
This species has a relatively small breeding range and a global population estimated at 216.000 individuals. The population is stable at high elevation, but declining at lower altitudes and in fact disappeared from some areas of the island. The decline is mostly caused by habitat degradation through heavy browsing by feral ungulates, as well as diseases, such as avian pox and malaria, which are spread by mosquitoes, and a problem at low and middle elevations. Conservation actions underway include unsuccessful attempts to remove goats and sheep from Mauna Kea, control of feral cats and habitat restoration and reforestation at mid and high elevations on Hawai`i. Fencing is underway on Mauna Kea to protect palila Loxioides bailleui critical habitat by excluding ungulates, which should benefit the Hawaii Elepaio.

Common name:
Tahiti monarch (en); monarca-do-Taiti (pt); monarque de Tahiti (fr); monarca de Tahiti (es); Tahitimonarch (de)

Taxonomy:
Order Passeriformes
Family Monarchidae

Range:
This species is endemic to the island of Tahiti, in French Polynesia. Even within the island it is restricted to just 4 lowland valleys.

Size:
The Tahiti monarch is 15 cm long and weighs 25 g.

Habitat:
They are found in tropical and subtropical forests dominated by mara Neonauclea forsteri, being present at altitudes of 80-400 m.

Diet:
They forage both in the canopy and the undergrowth of the forests, taking various insects.

Breeding:
Tahiti monarchs breed in October-February. They build a a cup-shaped nest made of moss and decorated with cobwebs, where the female lays a single egg. The egg is incubated for 15–17 days and the chicks fledge 3 weeks after hatching.

Conservation:
IUCN status - CR (Critically Endangered)
This species has an extremely restricted breeding range and a global population of just 35-50 birds. Since 2004, the species has shown signs of recovery, with new pairs becoming established in abandoned territories, mostly thanks to the conservation measures that were put in place. The main threats to this species are the decline in habitat quality caused by the spread of invasive plant species, such as the African tulip tree Spathodea campanulata, but also the predation by introduced black rats Rattus rattus, and goat grazing is leading to habitat degradation in some areas. Predation by cats and swamp harrier Circus approximans and competition with other passerines may also have a negative impact on this species. Rat control around nests, using poison and tree bands, as well as some control of invasive plant species has had some success in preserving this species.

Seychelles paradise-flycatcher

Terpsiphone corvina


Common name:
Seychelles paradise-flycatcher (en); monarca-das-Seychelles (pt); tchitrec des Seychelles (fr); monarca-colilargo de las Seychelles (es); Seychellen-paradiesschnäpper (de)

Taxonomy:
Order Passeriformes
Family Monarchidae

Range:
This species is endemic to the Seychelles archipelago, being mostly found in La Digue, but also in Marianne, Praslin and Félicité.

Size:
The males are considerably longer than females because of their long tail feathers. Males are 22-31 cm lon while female are 17-20 cm long.

Habitat:
This species depends on takamaka (Calophyllum inophyllum) and badamier (Terminalia catappa) woodland, particularly near marshy areas and water bodies.

Diet:
The Seychelles paradise-flycatcher is strictly insectivorous, gleaning insects and spiders from the leaves. Dragonflies, mosquitoes, grasshoppers and butterflies seem to form the bulk of their diet.

Breeding:
Breeding can occur all year round, although there appears to be a peak in activity in November-April. The oval bowl-shaped nest is built on branches and consists of twigs, palm fibre, and spider webs. The female lays just 1 white egg with reddish-brown spots. The egg is incubated for 17 days and the chicks fledge 14-15 days after hatching but continue to be fed by the parents for another 2 months.

Conservation:
IUCN status - CR (Critically endangered)
The Seychelles paradise-flycatcher has an extremely small breeding range and the global population in currently estimated at just 210-280 individuals. The species is mostly threatened by the alarming rates of habitat loss and fragmentation, due to tourism and private housing developments but also because of a wild disease affecting takamaka stands. Nest depredation by alien mammals is another significant threat. Conservation measures, namely habitat restoration, the protection of water quality in the wetlands and pest elimination has lead the population to recover from an historic minimum of 50-60 individuals in the 1980s and the current population trend seems to be stable.
