Bird of Paradise

Blue Bird of Paradis:


The Blue Bird-of-paradise, Paradisaea rudolphi, is a medium-sized with a bluish-white bill, dark brown iris, grey legs, broken white eye-ring and bright blue wings. The male is adorned with violet blue and cinnamon flank plumes and two long ribbon-like tail feathers. The female has a chestnut brown below.
The Blue Bird-of-paradise is endemic to Papua New Guinea. It is distributed to mountain forests of southeastern New Guinea. ITIS recognizes only one subspecies, but additional subspecies margaritae and ampla have been described. The male is polygamous and performs a breathtaking courtship display. But unlike all other Paradisaea species, he performs solitary with attending female nearby. In display, the male hangs from a branch upside down. The black oval with red margin at the centre of his chest is rhythmically enlarged and contracted. His violet blue plumes spread out in a fan, swaying its body back and forth while the central tail feathers form two impressive arches down to either side. Throughout his performance he vocalizes softly in a low but harsh vibrating voice.
Regarded by some ornithologists as the loveliest of all birds, the Blue Bird-of-paradise was discovered by Carl Hunstein in 1884. The scientific name commemorates the ill-fated Crown Prince Rudolf of Austria.
Due to ongoing habitat loss, limited range, small population size and hunting in some areas for its highly prized plumes, the rare Blue Bird-of-paradise is classified as Vulnerable on the IUCN Red List of Threatened Species.
Goldies Bird of Paradise:

The Goldie's Bird-of-paradise, Paradisaea decora is a large, approximately 33 cm long, olive-brown bird-of-paradise. The male has a yellow and dark green plumage with a lavender grey breast, yellow iris and grey colored bill, mouth and feet. It is adorned with large crimson ornamental flank plumes and two long tail wires. The male is distinguished from other Paradisaea species by its lavender grey breast plumage. Unadorned female has an olive-brown plumage with cinnamon-brown below.
Endemic to Papua New Guinea, the Goldie's Bird-of-paradise is distributed in the hill forests of Fergusson and Normanby Island of the D'Entrecasteaux Archipelago, eastern Papuan Islands. The diet consists mainly of fruits.
The name commemorates the Scottish collector Andrew Goldie, who discovered the bird in 1882.Due to ongoing habitat loss, limited range and overhunting in some areas, the Goldie's Bird-of-paradise is evaluated as Near Threatened on the IUCN Red List of Threatened Species.

Hawaii’s Endangered Birds

Hawaii’s Endangered Birds: Wake Up, Already!

 
 
I’m as surprised as anyone to find myself turning into a bird watcher—it’s a short walk from where I am to high-waisted cargo pants, a vest full of pockets and a pair of binoculars that will allow me to see well into the next county. (I kid, I kid. Bird watchers come in all shapes, sizes and victims of fashion.) My affection for all things avian is why I was saddened to read the report on Hawaii’s failing bird population.

The Bali Mynah

The Bali Mynah
 


The Bali Mynah is distributed and endemic to the island of Bali, where it is the island's only surviving endemic species.  This rare bird was discovered in 1910 and is one of the world's most critically endangered birds.   In fact, it has been hovering immediately above extinction in the wild for several years.


The last stronghold of the species is at Bali Barat National Park; about 1,000 individuals are believed to be held in captivity legally.  In fact, the Bali Starling is so much in danger that that national park has been set up just for the Bali Starling's survival.

Male and female Bali mynahs look alike, having beautiful white feathers, black tipped wings and tails, and a bright powder blue crescent of skin around the eyes. Their heads are topped off by a lacy white crest of feathers. They are about the size of cardinals.

he Bali Starling is listed in Appendix I of CITES. Trade even in captive-bred specimens is strictly regulated and the species is not generally available legally to private individuals. However, experienced aviculturalists may become affiliated with the captive-breeding program, allowing them to legally keep this species.

Poaching and timber harvesting are among the greatest threat to the survival of the Bali mynah in the wild. Conservation initiatives enacted over the past two decades to have been ineffective in increasing this species numbers in the wild.

Red tailed black cockatoo

Red tailed black cockatoo

Image

Following on from last week's WW post about a really noisy winged visitor ... this week I'd like to introduce another loud and raucous visitor to our garden.  We see them quite regularly throughout the year ... well, we generally hear their harsh grating shrieks first!!

They're mainly arboreal and love foraging in the canopies of the Eucalyptus and Acacia trees.

This is the magnificent Red-Tailed Black Cockatoo.  There are four sub-species of this bird, but it is Calyptorhynchus banksi macrorhynchus that is quite a common sight across western, northern and eastern Australia.  While both the male and the female have a short crest, a stubby beak and a long tail ... there are some differences.  

The male is jet black, with a broad band of bright red in his tail and a dark grey beak.



The female is duller black, with yellow speckles on the head and breast, and yellow patches in her tail. Her beak is whitish in colour.


A female will lay two eggs but only one young ever grows up to leave the hollow in a tree in which the eggs are laid.


Around here, we usually only see these birds in small groups of males and females.  Further out west, they can be spotted in flocks of over 1000 birds.   There is a common 'bush myth' here in Oz ... no, nothing to do with the ex-President of the US ... it's all about these beautiful black birds.  Apparently if you see three of the these cockatoos together ... that means rain is three days away.  If you're travelling in the outback and you see two thousand ... yes ... that's how many day until the next rain!  I'm not sure where these massive flocks of cockatoos are finding food out there, when there's supposed to be drought for months on end!

Another interesting fact about these beauties ... some of these birds have been known to live for 100 years in captivity.  In the wild, they can live to around 20 years.

There are a couple of other bloggers who have also posted interesting posts that fit in with the Wildlife on Wednesday theme ... so please check them out!

This "touching image" of two orange-bellied parrots won the category for critically endangered migrating birds, according to a World's Rarest Birds contest statement.
The small parrot breeds only in southwestern Tasmania (see map) and migrates to southeastern Australia in the winter, where agriculture and development are crowding out its habitat. Probably fewer than 150 animals remain in the wild, according to BirdLife International.

Northern Cardinal

Northern Cardinal

The Northern Cardinal (Cardinalis cardinalis) or Redbird is a North American bird in the cardinal family. It is found from southern Canada through the eastern United States from Maine to Texas and south through Mexico to northern Guatemala and Belize. It can also be found on the Big Island of Hawaii. It is found in woodlands, gardens, shrublands, and swamps. The Northern Cardinal is a mid-sized songbird with a body length of 21–23 centimeters (8.3–9 in). It has a distinctive crest on the head and a mask on the face which is black in the male and gray in the female. It displays sexual dimorphism in its coloration; the male is a vibrant red, while the female is a dull red-brown shade. The Northern Cardinal is mainly granivorous, but also feeds on insects and fruit.




Golden Pheasant

Golden Pheasant

The Golden Pheasant or “Chinese Pheasant”, (Chrysolophus pictus) is a gamebird of the order Galliformes (gallinaceous birds) and the family Phasianidae. It is native to forests in mountainous areas of western China but feral populations have been established in the United Kingdom and elsewhere. The adult male is 90-105 cm in length, its tail accounting for two-thirds of the total length. It is unmistakable with its golden crest and rump and bright red body. The deep orange “cape” can be spread in display, appearing as an alternating black and orange fan that covers all of the face except its bright yellow eye, with a pinpoint black pupil.






Rainbow Lorikeet

Rainbow Lorikeet

The Rainbow Lorikeet is very colourful – almost every colour of the rainbow can be found on their feathers. They are not large birds, with a Rainbow Lorikeet’s length ranging from 25–30 cm (9.8-11.8 in) in size, and have a wingspan of about 17 cm (6.7 in). The Rainbow Lorikeet, Trichoglossus haematodus is a species of Australasian parrot found in Australia, eastern Indonesia (Maluku and Western New Guinea), Papua New Guinea, New Caledonia, Solomon Islands and Vanuatu. In Australia, it is common along the eastern seaboard, from Queensland to South Australia and northwest Tasmania. Its habitat is rainforest, coastal bush and woodland areas.




American Goldfinch

American Goldfinch


The American Goldfinch (Spinus tristis), also known as the Eastern Goldfinch and Wild Canary, is a North American bird in the finch family. It is migratory, ranging from southern Canada to North Carolina during the breeding season, and from just south of the Canadian border to Mexico during the winter. The American Goldfinch is a granivore and adapted for the consumption of seedheads, with a conical beak to remove the seeds and agile feet to grip the stems of seedheads while feeding. It is a social bird, and will gather in large flocks while feeding and migrating. It may behave territorially during nest construction, but this aggression is short-lived. Its breeding season is tied to the peak of food supply, beginning in late July, which is relatively late in the year for a finch. This species is generally monogamous, and produces one brood each year.






Scarlet Tanager

Scarlet Tanager

The Scarlet Tanager (Piranga olivacea) is a medium-sized American songbird. Formerly placed in the tanager family (Thraupidae), it and other members of its genus are now classified in the cardinal family. The species’s plumage and vocalizations are similar to other members of the cardinal family.




Hyacinth Macaw

Hyacinth Macaw

Native to central and eastern South America, the Hyacinth Macaw (Anodorhynchus hyacinthinus), or Hyacinthine Macaw, is the largest macaw and the largest flying parrot species in the world, though the flightless Kakapo of New Zealand can outweigh it at up to 3.5 kg. In terms of length it is larger than any other species of parrot. While generally easily recognized, it can be confused with the far rarer Lear’s Macaw. Their popularity as pets has taken a heavy toll on their population in the wild.




Birds of Paradise

Birds of Paradise


The birds-of-paradise are members of the family Paradisaeidae of the order Passeriformes. The majority of species in this family are found on the island of New Guinea and its satellites, with a few species occurring in the Moluccas of Indonesia and eastern Australia. The family has forty species in 13 genera. The members of this family are perhaps best known for the plumage of the males of most species, in particular highly elongated and elaborate feathers extending from the beak, wings or head. For the most part they are confined to dense rainforest habitat. The diet of all species is dominated by fruit and to a lesser extent arthropods. The birds-of-paradise have a variety of breeding systems, ranging from monogamy to lek based polygamy.






The World of Pigeon

Passion, Game and Income source

Pigeons are usually found in villages where there are ample lofts for the birds to nest as well as reproduce. Breeding pigeons, both commercially and as a hobby, has its own merits as they are a great source for income generation on top of being a peaceful and serene pet. Commercial breeding of pigeons takes very little investment of money and space; such an operation can be commenced by utilising a few thousand takas and a miniscule area such as a terrace or veranda.
There are more than 2,000 pigeon breeders in Dhaka city with more than 20,000 scattered across the country, especially in Chittagong, Dinajpur, and Barisal. However all is not well. Pigeon trafficking is a very lucrative underground business with a annual turnover of Tk 10 crores. According to Tanvir Hassan, general secretary of Bangladesh Fancy Pigeon Breeders Association (BFPBA), a bunch of criminals are involved in smuggling pigeons from Bangladesh to India. While visiting Kaptan Bazaar, this reporter found there are three major pigeon haats around Dhaka city – Tongi, Kaptan, and Jinjira Bazaar – where pigeons are illegally captured and sold by yet another criminal syndicate……

african ring-neck dovesAfrican Ring-neck Doves
Our exotic ring-neck doves were brought in as discarded as pets. Being African they would not survive in our harsh winter months. During the summer and early fall they enjoy our warm Muskoka weather but during the winter they have the heat and security of the barn.



Diamond Doves






White Dove










Male Diamond Dove (Blue White Rump), 7 months old




These are the type that unscrupulous/unknowledgeable breeders are selling as "Silver Diamond Doves." They are not. They are simply the wild color Diamond Dove with a White Rump gene (which also dilutes the color of the whole body.) They have very dark (almost black) primary wing feathers. These are a very beautiful and very COMMON variety.
