This set features such herons as the majestic Great Blue Heron, the secretive Green Heron, the endangered Japanese Night Heron and the exotic Bare-throated Tiger Heron of the Yucatan. Also included are many of the common Bitterns from around the world. Overview and Use The set is located within the Animals : Songbird ReMix folder. Here is where you will find a number of folders, such as Bird Library, Manuals and Resources . Let's look at what is contained in these folders: o Bird Library: This folder holds the actual species and poses for the "premade" birds. Birds are placed into a "type" folder (such as "Birds of Prey (Order Falconiformes)" which for example would hold falcons, hawks and eagles). The birds for this set can be found in the following folder(s): . Herons, Ibises and Pelicans (Order Pelecaniformes) o Manuals: Contains a link to the online manual for the set. o Props: Contains any props that might be included in the set o Resources: Items in this folder are for creating and customizing your birds . Bird Base Models: This folder has the blank, untextured model(s) used in this set. These models are primarily for users who wish to experiment with poses or customize their own species of bird. With using physical renderers such as Iray and Superfly, SubD should be turned to at least “3”. For DAZ Studios 3Delight renders, the SubD must be turned from the “High Resolution” setting to the “Base” setting (otherwise some areas will render incorrectly transparent). Poser Use Select Figures in the Runtime Folder and go to the Animals : Songbird ReMix folder. Select the bird from the renderer Firefly or Superfly) folder you want and simply click it to load. Some birds in the Songbird ReMix series may load with attached parts (Conformers) such as tail or crest extensions. Some of these parts have specific morphs. You will need to click on the attached part to access those controls. Associated poses can be found in the same folder- Bird Library : (Type) : Poses. DAZ Studio Use Go to the Animals : Songbird ReMix folder. Select the bird from the renderer (3Delight or Iray) folder you want and simply click it to load. Some birds in the Songbird ReMix series 3 may load with attached parts (Conformers) such as tail or crest extensions. Some of these parts have specific morphs. You will need to click on the attached part to access those controls. Associated poses can be found in the same folder- Bird Library : (Type) : Poses. Note: Using the "Apply this Character to the currently selected Figure(s)" option will not properly apply the correct scaling to the bird selected. It is better to delete the existing character first and load the one you want to use. Physical-based Rendering Iray and Superfly requires more CPU and memory horsepower than the legacy renderers because of ray-trace bounces and higher resolution meshes needed for displacement. Poser’s Superfly renderer will require that the “Min Transparent Bounces” be set to at least 16 and that the “Max Transparent Bounces” be set to at least 32 in render settings. Superfly renders may show artifacts in the head area. This is a known Poser issue and may be addressed in the future. Increasing the SubD may minimize this issue. Birds in Flight Long-necked shorebirds will fly differently depending on their species; some fly with their necks out stretched while other fly with their necks bunched in a “U” shaped position. These birds often have the same neck pose when not in flight. Here’s a guide to help you choose the correct pose: Out-stretched Neck Cranes, Ibises, Spoonbills and Storks “U”-shaped Neck Egrets and Herons In addition, when the thighs are pulled back, often they appear ‘lumpy’ in the model. Each Thigh section has to ‘SmoothThigh4Flight’ morph to correct this. This morph is used in the flight poses that are provided. 4 Other Posing Tips Heron Head Plumes The majority of herons included in this volume have head plumes. While you can pose them by directly selecting the plume part, it will be easier to access them using the Head part of the model. Located in the “Crest” section of the head morphs you’ll find EZ-Pose controls for both the right and left head plumes. Use of the “NeckInflate” morphs Bitterns and the Bare-throated Tiger Heron are often seen with their neck inflated. Bitterns often do this when making their booming calls. Two morphs (NeckInflate and NeckInflate2 which are found in the HIP section under “Creation Morphs”) can be used to simulate that behavior. These two morphs will work best with the neck straight or with minimal bending to Neck Sections 1 and 2. Use of the “ThroatSag” morph This morph (found in the HEAD section under “Creation Morphs”) can used in conjunction with the NeckInflate morphs or to simulate swallowing or eating. 5 Where to find your birds Type Folder Bird Species American Bittern Australasian Bittern Eurasian Bittern Little Bittern Yellow Bittern Bare-throated Tiger Heron Herons, Ibises and Pelicans Black-crowned Night Heron (Order Pelecaniformes) Chinese Pond Heron Great Blue Heron Green Heron Grey Heron Japanese Night Heron Little Blue Heron (all variations) Purple Heron Where to find your poses Type Folder For what species?

Found along calm freshwater and seacoasts. Usually nests in trees near water, but colonies can be found away from water. Status: Least Concern. Global population: 6,500. The Great Blue Heron suffered less from plume hunters and pesticides than other herons which occurred between 1850 and 1970, and its numbers have remained strong. Protected under the Migratory Bird Treaty Act of 1918. Diet: Fish, invertebrates, amphibians, reptiles, birds, and small mammals. Although this heron eats primarily fish, it is adaptable and willing to eat other animals as well. Several studies have found that voles (mice) were a very important part of the diet, making up nearly half of what was fed to nestlings in Idaho. Occasionally a heron will choke to death trying to eat a fish that is too large to swallow. Nesting: This species usually breeds in monospecific colonies, in trees close to lakes or other wetlands; often with other species of herons. Sexes are similar in appearance. Juvenile similar to adult, but has gray crown, a dark upper bill, rusty brown edging to back feathers, and lacks body plumes Colony groups are called heronry (a more specific term than "rookery"). The size of these colonies may be large, ranging between 5–500 nests per colony, with an average of approximately 160 nests per colony. 8 Great Blue Herons build a bulky stick nest, and the female lays three to six pale blue eggs. One brood is raised each year. If the nest is abandoned or destroyed, the female may lay a replacement clutch. Reproduction is negatively affected by human disturbance, particularly during the beginning of nesting. Repeated human intrusion into nesting areas often results in nest failure, with abandonment of eggs or chicks. Both parents feed the young at the nest by regurgitating food. Parent birds have been shown to consume up to four times as much food when they are feeding young chicks than when laying or incubating eggs. Eggs are incubated for approximately 28 days and hatch asynchronously over a period of several days. The first chick to hatch usually becomes more experienced in food handling and aggressive interactions with siblings, and so often grows more quickly than the other chicks. Predators of eggs and nestlings include turkey vultures, several corvids, hawks, bears and raccoons, the latter two also potential predators of adults. Adult herons, due to their size, have few natural predators, but can be taken by bald eagles, great horned owls and, less frequently, red-tailed hawks. When predation on an adult or chick occurs at a breeding colony, the colony can be abandoned by the other birds, but this does not always occur. Cool Facts: An all-white Caribbean population was once known as a separate species, the Great White Heron.

  • Report of the Independent Bird Survey, Bijarim Ro, Jeju, June 2019
    Report of the Independent Bird Survey, Bijarim Ro, Jeju, June 2019 th Nial Moores, Birds Korea, June 24 2019 Photo 1. Black Paradise Flycatcher, Bijarim Ro, June 2019 © Ha Jungmoon 1. Survey Key Findings In the context of national obligations to the Convention on Biological Diversity; and in the recognition of the poor quality of the original assessment in June 2014 which found only 16 bird species in total and concluded that the proposed road-widening would cause an “insignificant” impact to wildlife and no impact to Endangered species (because there are no Endangered animal species in the area), this independent bird survey conducted on June 10th and 11th and again from June 14th-19th 2019 concludes that forested habitat along the Bijarim Ro is of high national and probably of high international value to avian biodiversity conservation. Although this survey was limited in time and scope (so that the populations of many species were likely under-recorded), and very little time was available to conduct additional research for this report and for translation (five days total), our survey findings include: (1) 46 species of bird in total, including six species of national conservation concern; (2) 13 territories of the nationally Endangered Fairy Pitta Pitta nympha and 23 territories of the nationally Endangered Black Paradise Flycatcher Terpsiphone atrocaudata within 500m of the Bijarim Ro, with several of these territories within 50m of the road; (3) Three territories of the nationally and globally Endangered Japanese Night Heron Gorsachius goisagi, at least two of which were within 500m of the Bijarim Ro.

  • Status Update on White-Eared Night Heron Gorsachius Magnificus in South China
    Bird Conservation International (2001) 11:101–111. BirdLife International 2001 Status update on White-eared Night Heron Gorsachius magnificus in South China Nycticorax magnifica Ogilvie-Grant, 1899, Ibis (7) 5: 586 JOHN R. FELLOWES, ZHOU FANG, LEE KWOK SHING, BILLY C.H. HAU, MICHAEL W.N. LAU, VICKY W.Y. LAM, LLEWELLYN YOUNGand HEINZ HAFNER Summary White-eared Night Heron Gorsachius magnificus is probably the most threatened heron species in the world, and the highest priority for heron species conservation. From 1990 to 1998, there were sightings from only six localities in the wild. There are none in captiv- ity. In 1998 a caged bird was found in a wildlife market in the city of Nanning, Guangxi Zhuang Autonomous Region, People’s Republic of China. This finding prompted a 12- month survey in 1998–1999 of both markets and potential habitats in Guangxi. Several captured birds provided direct evidence of the existence of small populations in Guangxi and Guangdong Provinces. The respective habitats were surveyed in spring 2000, with emphasis on observations at dusk. The species was seen at two locations. Although some of the captured birds came from highly degraded habitat, the best sites seemed to be in areas near extensive primary forests, with streams, rice fields and marshes. The informa- tion obtained will be used to compile a detailed Action Plan designed to prevent the extinction of the species. Introduction Since its discovery in the 1890s, there have been only a few confirmed records of White-eared Night Heron Gorsachius magnificus, from scattered localities in China and Vietnam (Styan 1902; La Touche 1913, 1917;Geeet al.

  • First Breeding Record of Japanese Night Heron Gorsachius Goisagi in Korea
    Ornithol Sci 9: 131–134 (2010) ORIGINAL ARTICLE First Breeding Record of Japanese Night Heron Gorsachius goisagi in Korea Hongshik OH1,#, Youngho KIM1 and Namkyu KIM2 1 Department of Science Education, Jeju National University, Jeju 690–756, Republic of Korea 2 Korea International Photo Movie Interchange Association, IdoI-dong, Jeju-si, Jeju Special Self-governing Province 690–120, Republic of Korea Abstract We studied the breeding biology of the Japanese Night Heron Gorsachius ORNITHOLOGICAL goisagi from 21 June to 2 August 2009. This species was previously considered an SCIENCE endangered endemic breeding species of southern Japan only, but was found breeding © The Ornithological Society in a valley at the bottom of Mt. Halla at Ara-dong, Jeju City, the southernmost island of Japan 2010 of Korea. This marks the first record of this species ever to be found breeding in Korea. The forested area consisted predominantly of plants such as Morus bombycis, Cryptomeria japonica, Styrax japonica, Orixa japonica, Viburnum dilatatum, and Lindera erythrocarpa. Materials for the nest were largely M. bombycis, followed by S. japonica, C. japonica, and so forth. There were three eggs in the clutch, and the brooding period lasted for 42 days. A close look into the pellets demonstrated that their main prey items were earthworms, snails, and cicadas. The results of this study represent valuable data, allowing for the mapping out of new methods for managing Gorsachius goisagis, a species currently on the brink of extinction. Key words Breeding record, Conservation, Gorsachius goisagi, Japanese Night Heron, Jeju Island The Japanese Night Heron Gorsachius goisagi a Environment of the Republic of Korea as a Class II species belonging to the Ardeidae family in the Ci- endangered species and is now under close protec- coniiformes order, resembles other night herons, but tion.
