  • Grounded Birds in New Zealand
    Flightless Grounded Birds in New Zealand An 8th Grade Research Paper By Nathaniel Roth Hilltown Cooperative Charter Public School June 2014 1 More than half of the birds in New Zealand either can’t fly, can only partially fly, or don’t like to fly. (Te Ara) This is a fact. Although only sixteen species in New Zealand are technically flightless, with another sixteen that are extinct (TerraNature), a majority of more than 170 bird species will not fly unless their lives are threatened, or not even then. This is surprising, since birds are usually known for flying. A flightless bird is a bird that cannot fly, such as the well­known ostrich and emu, not to mention penguins. The two main islands southeast of Australia that make up New Zealand have an unusually diverse population of these birds. I am personally very interested in New Zealand and know a lot about it because my mother was born there, and I still have family there. I was very intrigued by these birds in particular, and how different they are from most of the world’s birds. I asked myself, why New Zealand? What made this tiny little country have so many birds that can’t fly, while in the rest of the world, hardly any live in one place? My research has informed me that the population and diversity of flightless birds here is so large because it has been isolated for so long from other land masses. Almost no mammals, and no land predators, lived there in the millions of years after it split from the Australian continent, so flying birds didn’t have as much of an advantage during this time.

Collectors, both young and old, would often spend whole days and sometimes longer trips in a wide variety of different habitats, from sea shores to moorlands, wetlands to craggy mountainsides, searching for birds’ nests and the bounty to be found within them. Once collectors had found and taken eggs, they emptied out the contents; hence, they were really egg shell collectors. Some egg collectors claimed that egg-collecting was not just a hobby but a science, going by the name of oology, and seeking to establish oology as a recognised sub- discipline of ornithology, these collectors or oologists established formal institutions such as associations and societies, attended meetings where they exhibited unusual finds, and also contributed to specialist publications dedicated to oology.

  • Functional Traits of the World's Late Quaternary Large-Bodied Avian And
    www.nature.com/scientificdata OPEN Functional traits of the world’s late Data Descriptor Quaternary large-bodied avian and mammalian herbivores Erick J. Lundgren 1,2,3 ✉ , Simon D. Schowanek2,3 ✉ , John Rowan4, Owen Middleton 5, Rasmus Ø. Pedersen 2,3, Arian D. Wallach1, Daniel Ramp 1, Matt Davis2,3,6, Christopher J. Sandom5 & Jens-Christian Svenning 2,3 Prehistoric and recent extinctions of large-bodied terrestrial herbivores had signifcant and lasting impacts on Earth’s ecosystems due to the loss of their distinct trait combinations. The world’s surviving large-bodied avian and mammalian herbivores remain among the most threatened taxa. As such, a greater understanding of the ecological impacts of large herbivore losses is increasingly important. However, comprehensive and ecologically-relevant trait datasets for extinct and extant herbivores are lacking. Here, we present HerbiTraits, a comprehensive functional trait dataset for all late Quaternary terrestrial avian and mammalian herbivores ≥10 kg (545 species). HerbiTraits includes key traits that infuence how herbivores interact with ecosystems, namely body mass, diet, fermentation type, habitat use, and limb morphology. Trait data were compiled from 557 sources and comprise the best available knowledge on late Quaternary large-bodied herbivores. HerbiTraits provides a tool for the analysis of herbivore functional diversity both past and present and its efects on Earth’s ecosystems. Background & Summary Large-bodied terrestrial avian and mammalian herbivores strongly infuenced terrestrial ecosystems through much of the Cenozoic–the last 66 million years of Earth history. However, many of the world’s large-bodied her- bivore species became extinct or experienced signifcant range contractions beginning ~100,000 years ago in the late Quaternary.
