Additional Records of Passerine Terrestrial Gaits
ADDITIONAL RECORDS OF PASSERINE TERRESTRIAL GAITS GEORGE A. CLARK, JR. The varied methods of locomotion in birds pose significant problems in behavior, ecology, adaptation, and evolution. On the ground birds progress with their legs moving either synchronously (hopping) or asynchronously (walking, running) as the extreme conditions. Relatively terrestrial species often have asynchronous gaits, whereas primarily arboreal species are typically synchronous on the ground. Particularly important earlier studies on passerines are Kunkels’ (1962) comparative behavioral survey and Riiggebergs’ (1960) analysis of the morphological correlates of gaits. Over several years I have noted gaits for 47 passerine species in the U.S., En- gland, and Kenya, and have examined many references. I here sum- marize behavioral records for families not mentioned by Kunkel (1962) and also for species with gaits markedly unlike those of confamilial species discussed by him. My supplementary review is selective rather than ex- haustive with the aim of indicating more fully the distribution of gaits among the passerine families. Regional handbooks, life history studies, and other publications contain numerous additional records, but I know of none that negate the conclusions presented here. J. S. Greenlaw (in prep.) has reviewed elsewhere the passerine double-scratch foraging be- havior that has at times previously been discussed in connection with gaits (e.g., in Hailman 1973). VARIATION WITHIN SPECIES Gaits often vary within a species (Kunkel 1962, Hailman 1973, Schwartz 1964, Gobeil 1968, Eliot in Bent 1968:669-670, this study). As an addi- tional example, I have seen Common Grackles (Quisc&s quiscula) hop in contrast to their usual walk. -

Early South Australian Records of the Western Grasswren Amytornis Textilis Myall
Aerial diving display, with calling, by Black Falcon Falco subniger D.J. Whelan 24 Manning Boulevard, Darley VIC 3440, Australia Email: [email protected] Australian Field Ornithology 2014, 31, 43–49 Early South Australian records of the Western Grasswren Amytornis textilis myall Andrew B. Black South Australian Museum, North Terrace, Adelaide SA 5000, Australia Email: [email protected] Summary. Records show that the naturalist–collector F.W. Andrews provided five specimens of the Western Grasswren Amytornis textilis myall from the Gawler Ranges for the South Australian Museum, Adelaide (SAMA), in the 1870s, but there is evidence suggesting that he obtained others in that period. Two of these specimens are retained in the collection of the Institut royal des Sciences naturelles de Belgique, Brussels, Belgium, and one each in the Muséum national d’Histoire naturelle, Paris, France, and the Macleay Museum, Sydney. Four ‘Amytis textilis’ sent elsewhere have not been located recently and another two were evidently discarded from the SAMA around 1882. The first of the records that these specimens represent precedes the previously acknowledged earliest observations of the northern Eyre Peninsula– Gawler Ranges subspecies in 1902 by 31 years (Chenery 1903) and the recognition of their taxonomic status by 45 years (Mathews 1916). Introduction The first to publish a report of the Western Grasswren Amytornis textilis (Quoy & Gaimard, 1824) in South Australia (SA) was Chenery (1903) although he did not name it, simply listing it as ‘Amytis – (?)’. He and Morgan (1924) saw these grasswrens on Nonning and Mount Ive Stations, central Gawler Ranges, in August 1902 and took two specimens, which Morgan donated ~10 years later to the South Australian Museum, Adelaide (SAMA) (B7359 and B7360) (Zietz 1913). -

Until recently the species A. textilis was recognised across Australia, however since 2010 the eastern and western populations have been placed in A.m modestus (Thick-billed Grasswren) and Amytornis textilis (Western Grasswren), respectively (Christidis et al. 2010).

Photo - Richard Manning Return to 1616 – Ecological Restoration Project Dirk Hartog Island is Western Australia’s largest island. When visited by Dirk Hartog in 1616, the island was in pristine condition with a rich mammal fauna and flourishing vegetation. Since this first European landing on Australian soil, introduced plants and animals have degraded the island causing the local extinction of native species. Return to 1616 is an ambitious project helping to restore the island’s natural ecosystems. Introduced sheep and goats have been removed because their grazing and trampling damages native plants and reduces the food and shelter available for native animals. Feral cats are efficient hunters and have been eradicated from the island to make it safe for native animal species that are gradually being returned. These are the Shark Bay bandicoot, dibbler, chuditch, brush-tailed mulgara, greater stick-nest rat, desert mouse, Shark Bay mouse, heath mouse, woylie, boodie and western grasswren. In addition, rufous and banded hare-wallabies, have been included to improve their long-term survival. These animals are in need of conservation protection. Some are threatened and others extinct on the mainland. To find out more about the project, visit www. -

These changes are based on changes to species and nomenclature as recorded in the 62nd Supplement to the AOS Checklist, made available online by the AOS in late June 2020. In all cases additions and changes were thoroughly cross-checked for new conflicts and for the release of old conflicts. Unless stated it can be assumed that no new conflicts occurred. NUMB, CAT, PNO, and ORD codes (species number, category, species status, and order) are internal codes used by IBP, in part to resolve conflicts (see Pyle and DeSante 2003, listed on IBP's alpha-code page for details).
