Birds in Flight
Birds in Flight By W. P. Pycraft Birds in Flight CHAPTER I Concerning Wings "Divinity within them breeding wings wherewith to scorn the earth."— Milton. What a wing is—The quill feathers and their function—The skeleton of the wing—The muscles of the wing—The great air-chambers of the body—The Bat’s wing—The wing of flying Dragons—The wings of Dragon-flies and beetles. THE flight of birds has always aroused man’s envy and stirred his imagination. David longed for the wings of a dove: the writer of the Book of Proverbs tells us that “the way of an eagle” surpasses his understanding. Icarus, spurred on by dire necessity, actually, we are told, contrived to fly— but his maiden effort ended in disaster! To-day we have, in a sense, succeeded where he failed. But only because we have given up the idea of flight by personal effort, and make our aerial journeys in a flying machine. That we owe much of our success to a study of the flight of birds is common knowledge, but the machine which has evolved as a consequence of this study pursues its way through the air after a very different fashion from that of the birds, for its vast body is thrust, or drawn, through the air by means of a propeller, driven at incredible speed, its immobile wings sustaining the weight. The wings of the bird, on the other hand, not only lift the body from the earth, but they sustain it in the air by their marvellously complex movements. -
Newsletter No 31
P O Box 93, Wakkerstroom 2480 Cell Number 0822556778 E-Mail: [email protected] NEWSLETTER NUMBER 31– FEBRUARY 2015 Phragmites australis is a Perennial Grass that grows in the wetlands of the temperate and tropical regions of the world on all continents except Antarctica. It is thought to have originated from Phyrgia in Asia Minor. In Europe it is rarely invasive, it is even used as an ornamental plant, but everywhere else can be a major problem. It does have its uses; thatching, making arrows, youngsters eat it and it can be dried and ground into a fine powder that, when moistened, can be toasted like marsh mallows. In Egypt it is used for making a flute-like musical instrument, maybe that‟s why another name here in South Africa is Fluitjiesriet. Its most important use is for bioremediation where excess nutrients and pollutants are removed from dirty water and sewage pond waste water by bacterial action on the Phragmites roots and leaf litter. The downside is that it is highly invasive WoF operatives hard at work plant that crowds-out other wetland plant species reducing overall plant, animal and bird diversity. It can spread at the rate of 5m per year from horizontal runners, rhizomes up to 10m long that produce a new shoot every 300mm. It is allelopathic i.e. it releases toxins from its roots that stop the growth of other plants. It out-competes native plants for nutrients, water and sunlight. The outcome – a 3m plus tall, handsome plant that forms a deceptively beautiful monoculture! Phragmites is difficult to control and impossible to eradicate entirely. -

Breeding of the Black Redstart in Britain a Century-Old Record by George W
(110) BREEDING OF THE BLACK REDSTART IN BRITAIN A CENTURY-OLD RECORD BY GEORGE W. TEMPERLEY. IN 1916, seven years before T. A. Coward found the Black Redstart (Phcenicurus ochrurus gibraltariensis) breeding on the Sussex coast and so established what was then thought to be the first British record, F. C. R. Jourdain wrote an article in The Zoologist on the status of the Black Redstart in England as a breeding species. In that article he reviewed every alleged instance of breeding that had been reported up to that date and showed that in every such case an error in identification had been made—" with the possible exception of Hancock's .... which however requires confirmation before it can possibly be accepted." Hancock's record here referred to was published in 1874 in his Catalogue of the Birds of Northumber land and Durham and reads as follows :—" In 1845, a pair [of Black Redstarts] nested in the garden of the late Rev. James Raine, the historian of Durham, in that City; and I am indebted to Mr. Wm. Proctor for their nest, which is now in my collection. An egg belonging to it was kindly presented to me by the Rev. James Raine, son of the above named gentleman." William Proctor, who gave the nest to Hancock, was the curatOr- taxidermist of Durham University Museum. He had already published the record himself, for in a " List of Birds found in the County," published as an Appendix to the Rev. G. Ornsby's Sketches of Durham, in 1846, he had written thus of the Black Redstart— " Very rare ; a nest with five eggs was taken near Crook Hall in the summer of 1845." It will be noted that this was written just one year after the event and twenty-eight years before the publica tion of Hancock's " Catalogue." Additional details of the occurrence are to be found in a chapter by Canon H. -

Thick-Billed Warbler (Iduna Aedon) at Gambell, Alaska: First Record for North America Gary H
NOTES THICK-BILLED WARBLER (IDUNA AEDON) AT GAMBELL, ALASKA: FIRST RECORD FOR NORTH AMERICA GARY H. ROSENBERG, 8101 North Wheatfield Dr., Tucson, Arizona 85741; [email protected] PAUL E. LEHMAN, 11192 Portobelo Dr., San Diego, California 92124; [email protected] AARON J. LANG, 40208 Alpenglow Circle, Homer, Alaska 99603; [email protected] VICTOR AND RUBEN STOLL, 899 Miller Rd., Centerville, Tennessee 37033; [email protected] In the evening on 8 September 2017, in the “far boneyard” at Gambell, St. Law- rence Island, Alaska (63.78° N, 171.74° W), Victor and Ruben Stoll flushed a pas- serine they could not immediately identify. The “boneyards” are large pits excavated by the resident Yupik Natives seeking buried ivory and artifacts, a result of several thousand years of sea-mammal hunting from this island’s Northwest Cape. Working these pits turns the soil, which has resulted in the growth of relatively lush vegetation consisting of two species of Artemisia, known locally as “wormwood.” The combina- tion of lush vegetation (reaching 0.5–1 m in height) and deep depressions that offer protection from the wind is attractive to migrant and vagrant landbirds in the otherwise flat, gravelly landscape. Soon thereafter, we, along with Greg Scyphers, Monte Taylor, and other birders then at Gambell, converged at the far boneyard in search of the bird. It was soon relocated and seen on the ground briefly by Lang, who suggested it was a Thick-billed Warbler (Iduna aedon), a bird he was familiar with from southeastern Asia and a species not previously recorded in Alaska or North America. -
Based on Nuclear and Mitochondrial Sequence Data

Ericsona,* and Ulf S. Johanssona,b a Department of Vertebrate Zoology and Molecular Systematics Laboratory, Swedish Museum of Natural History, Frescativagen 44, P.O. Box 50007, SE-10405 Stockholm, Sweden b Department of Zoology, University of Stockholm, SE-106 91 Stockholm, Sweden Received 18 September 2002; revised 23 January 2003 Abstract Passerida is a monophyletic group of oscine passerines that includes almost 3500 species (about 36%) of all bird species in the world. The current understanding of higher-level relationships within Passerida is based on DNA–DNA hybridizations [C.G. Sibley, J.E. Ahlquist, Phylogeny and Classification of Birds, 1990, Yale University Press, New Haven, CT]. Our results are based on analyses of 3130 aligned nucleotide sequence data obtained from 48 ingroup and 13 outgroup genera. Three nuclear genes were sequenced: c-myc (498–510 bp), RAG-1 (930 bp), and myoglobin (693–722 bp), as well one mitochondrial gene; cytochrome b (879 bp). The data were analysed by parsimony, maximum-likelihood, and Bayesian inference. The African rockfowl and rock- jumper are found to constitute the deepest branch within Passerida, but relationships among the other taxa are poorly resolved— only four major clades receive statistical support. One clade corresponds to Passeroidea of [C.G. Sibley, B.L. Monroe, Distribution and Taxonomy of Birds of the World, 1990, Yale University Press, New Haven, CT] and includes, e.g., flowerpeckers, sunbirds, accentors, weavers, estrilds, wagtails, finches, and sparrows. -
Convergence in the Coerebidae
CONVERGENCE IN THE COEREBIDAE BY WILLIAM J. BEECHER ’ XTENSIVE efforts of the writer to find a sound anatomical basis for E determining the phylogenetic relationships of passerine families leave it clear that the hazard of adaptive convergence in bird systematics has been underestimated. The present analysis of convergence in the neotropical Honey Creepers (family Coerebidae) offers evidence that this is an artificial group. It appears to be composed, in fact, of nectar-adapted warblers (Parulidae) and nectar-adapted tanagers (Thraupidae) that have evolved convergently because of similarity of diet. The ConvergenceHazard in Taxonomy Sound systematic work in the higher categories demands sound criteria for clearly distinguishing between adaptation and phylogeny. The investigator at this level seesphylogeny through a screen of food and niche adaptations which often obscure true relationships. Such classic casesof convergence between Old and New World groups as were recently reviewed by Friedmann (1946) are obvious and constitute no hazard. But convergence between members of closely related groups occupying the same range may be such that the most expert taxonomists are unable to decide the true affinities on the basis of external characters alone (Beecher, 1950). This is no reflection on the taxonomists, who have generally been the first to recognize the problem, referring such moot groups as the Coerebidae to the comparative anatomist for additional evidence. But internal characters are not necessarily more reliable than external ones for indicating phylogeny. They are merely additional clues, often of a very conservative sort, but sometimes capable of adaptive changes as rapid as those known for any external features. Sclater (1886: 1) long ago observed that it was “in some instances difficult to distinguish” the Coerebidae from warblers on the one hand and tanagers on the other. -
Common Birds of the Estero Bay Area
Common Birds of the Estero Bay Area Jeremy Beaulieu Lisa Andreano Michael Walgren Introduction The following is a guide to the common birds of the Estero Bay Area. Brief descriptions are provided as well as active months and status listings. Photos are primarily courtesy of Greg Smith. Species are arranged by family according to the Sibley Guide to Birds (2000). Gaviidae Red-throated Loon Gavia stellata Occurrence: Common Active Months: November-April Federal Status: None State/Audubon Status: None Description: A small loon seldom seen far from salt water. In the non-breeding season they have a grey face and red throat. They have a long slender dark bill and white speckling on their dark back. Information: These birds are winter residents to the Central Coast. Wintering Red- throated Loons can gather in large numbers in Morro Bay if food is abundant. They are common on salt water of all depths but frequently forage in shallow bays and estuaries rather than far out at sea. Because their legs are located so far back, loons have difficulty walking on land and are rarely found far from water. Most loons must paddle furiously across the surface of the water before becoming airborne, but these small loons can practically spring directly into the air from land, a useful ability on its artic tundra breeding grounds. Pacific Loon Gavia pacifica Occurrence: Common Active Months: November-April Federal Status: None State/Audubon Status: None Description: The Pacific Loon has a shorter neck than the Red-throated Loon. The bill is very straight and the head is very smoothly rounded. -
