The Naturalist, on the Discovery and Exploration Ofnew Zealand
460 Conclusion. Inbringing to a close the record of the scrutiny and comparison of the evidences of the extinct wingless birds of New Zealand, some relaxation may be condoned by way of indulgence of the faculty of conjecture. The cause and conditions of the extinction of these birds, discussed inpp. 457-459, may be held to be determined, and, approximately, the date of their disappearance. But what can be said as to their origin? The first ground which suggests itself as a basis of speculation is, literally as well as figuratively, New Zealand itself. Since no evidence of such birds as those ranging in size from Notornis to the maximized form of Dinornis have been found in any other part of the globe, the conclusion seems legitimate that the species of those genera, as of Aptornis and Cnemiornis, did not exist elsewhere, at least on any known existing tract of dry land. The naturalist, on the discovery and exploration of New Zealand, recognized the rare circumstance that, save the Maori and his dog, no predatory land-animal existed in the islands which could have alarmed or endangered the existence of such birds as form the subject of the present work : nor has any evidence of such enemy been discovered in any stratum or locality of either the North or South Island. Itis, indeed, accepted as a notable fact in the geographical relations of living things, that, with the exception of some Bats and shore-haunting Seals, the mammalian class was unrepresented inNew Zealand prior to the comparatively recent advent of the Polynesian people. -
Beyond Endocasts: Using Predicted Brain-Structure Volumes of Extinct Birds to Assess Neuroanatomical and Behavioral Inferences

Studies on avian cranial and neuroanatomical evolution are strengthened by data on extinct birds, but complete, 3D-preserved vertebrate brains are not known from the fossil record, so brain endocasts often serve as proxies. Recent work on extant birds shows that the Wulst and optic lobe faithfully represent the size of their underlying brain structures, both of which are involved in avian visual pathways. The endocasts of seven extinct birds were generated from microCT scans of their skulls to add to an existing sample of endocasts of extant birds, and the surface areas of their Wulsts and optic lobes were measured. A phylogenetic prediction method based on Bayesian inference was used to calculate the volumes of the brain structures of these extinct birds based on the surface areas of their overlying endocast structures. This analysis resulted in hyperpallium volumes of five of these extinct birds and optic tectum volumes of all seven extinct birds. -
Ancient Bird Bones Redate Human Activity in Madagascar by 6,000 Years 12 September 2018
Ancient bird bones redate human activity in Madagascar by 6,000 years 12 September 2018 first arrived in Madagascar 2,400-4,000 years ago. However, the new study provides evidence of human presence on Madagascar as far back as 10,500 years ago—making these modified elephant bird bones the earliest known evidence of humans on the island. Lead author Dr. James Hansford from ZSL's Institute of Zoology said: "We already know that Madagascar's megafauna—elephant birds, hippos, giant tortoises and giant lemurs—became extinct less than 1,000 years ago. There are a number of theories about why this occurred, but the extent of human involvement hasn't been clear. Disarticulation marks on the base of the tarsometatarsus. These cut marks were made when removing the toes from the foot. Credit: ZSL Analysis of bones, from what was once the world's largest bird, has revealed that humans arrived on the tropical island of Madagascar more than 6,000 years earlier than previously thought—according to a study published today, 12 September 2018, in the journal Science Advances. A team of scientists led by international conservation charity ZSL (Zoological Society of London) discovered that ancient bones from the This chop mark would have been made with a large extinct Madagascan elephant birds (Aepyornis and sharp tool.

EPTRI - ENVIS Newsletter Vol. 10 No.4, 2004 Volume 10 No.4, 2004 The Eastern Ghats EPTRI - ENVIS Newsletter Estuarine Ecology of Eastern Ghats Foreword t was decided that we would bring out two issues of the Newsletter ‘The Eastern Ghats’ on Estuarine Ecology. This issue, Vol.10, No.4, 2004 includes the second and final part of the Iarticle: ‘Ecology and Biodiversity of Eastern Ghats – Estuaries of India’ by Rajendran, N et.al. We are pleased to include an article: ‘Coastal Follies and the Tsunami’ by Ashish Kothari and Manju Menon. The issue also contains the article: ‘Water Fowl Status at Coringa Wildlife Sanctuary, Andhra Pradesh’ by V. Vasudeva Rao, et.al. The stretch of Eastern Ghats from Orissa to Tamil Nadu , through Andhra Pradesh has numerous aspects of ecological importance. The endeavour, while bringing out the issues of this Newsletter, is to give importance to data gaps. Fragile eco-systems and hotspots of this broken mountainous terrain are important. Hence, an issue of this Newsletter would address this topic. We take this opportunity to draw the attention of our readers to send us articles and news clippings on ‘Fragile Ecosystems of Eastern Ghats,’ the theme of our forthcoming issue.

Jerdon's Courser, Once Thought to Be Extinct (Ripley 1952,1982, King 1981)
山階鳥研報 (J. Yamashina Inst. Ornith.), 21: 165-174, 1989 Systematics, Biogeography, and Conservation of Jerdon's Courser Rhinoptilus bitorquatus S. Dillon Ripley* and Bruce M. Beehler* Abstract A cladistic analysis of Jerdon's Courser (Rhinoptilus bitorquatus) and eight allied taxa supports the validity of the Afro-Asian genus Rhinoptilus and indicates that the sister-species of the Indian relict bitorquatus is the Three-banded Courser (Rhinoptilus cinctus) of eastern Africa. The present distribution of these two sister forms is evidence for a former biotic link between peninsular India and the savanna habitats of eastern Africa. This distributional trend is corroborated by an additional list of forty-three species or sister-species pairs that exhibit this Afro-Indian pattern. We believe that these data support the notion that there once existed an Afro-Indian fauna that inhabited what was probably a continuous belt of savanna from southern Africa to southern India. The recovery plan for the critically-endangered Jerdon's Courser should include at- tempts to develop a captive population of R. cinctus, which could then be used to rear eggs taken from wild populations of bitorquatus. Captive breeding, in concert with local educa- tion and efforts to expand protected areas of prime habitat, offers the most promising in- tegrated strategy for the species' recovery. Introduction Jerdon's Courser, once thought to be extinct(Ripley 1952,1982, King 1981),was rediscoveredin the hillsof southern Andhra Pradesh in January 1986 (Bhushan 1986a, 1986b). Although itis impossibleto presentlygive an accurateestimate of the distribu- tion and sizeof thisremnant population,the assumption is that the species'numbers are few and probably dissectedinto tiny subpopulations. -
