A Checklist of Somerset Birds The Somerset List to the end of 2014 contains 357 species. Using the BOURC classification 336 are in Category A, 18 in B and three in C. Golden Pheasant has been removed from the list as it is considered that there never was a self-sustaining population in Somerset. An explanation of the BOUC classification is given below. A Species that have been recorded in an apparently natural state at least once since 1 January 1950. B Species that have been recorded in an apparently natural state at least prior to 31 December 1949, but have not been recorded subsequently. C1 Naturalized introduced species - species that have occurred only as a result of introduction, e.g. Egyptian Goose Alopochen aegyptiacus C2 Naturalized established species – species with established populations resulting from introduction by Man, but which also occur in an apparently natural state, e.g. Greylag Goose Anser anser C3 Naturalized re-established species – species with populations successfully re-established by Man in areas of former occurrence, e.g. Red Kite Milvus milvus. C4 Naturalized feral species – domesticated species with populations established in the wild, e.g. Rock Pigeon (Dove)/Feral Pigeon Columba livia C5 Vagrant naturalized species – species from established naturalized populations abroad, e.g. possibly some Ruddy Shelducks Tadorna ferruginea occurring in Britain. There are currently no species in category C5. C6 Former naturalized species - species formerly placed in C1 whose naturalized populations are either no longer self-sustaining or are considered extinct, e.g. Lady Amherst’s Pheasant Chrysolophus amherstiae. D Species that would otherwise appear in Category A except that there is reasonable doubt that they have ever occurred in a natural state. Species placed in Category D only form no part of the British List, and are not included in the species totals. E Species recorded as introductions, human-assisted transportees or escapees from captivity, and whose breeding populations (if any) are thought not to be self-sustaining. Species in Category E that have bred in the wild in Britain are designated as E*. Category E species form no part of the British List (unless already included within Categories A, B or C). The table below also gives the reporting status against the species that are classed as requiring either County or National submissions. SOSRC (F) requires full description and SOSRC (S) short notes, whereas BBRC requires submission to the British Birds Rarity Committee. The SOSRC submissions form can be found here.

  • Importance of Tactile and Visual Stimuli of Eggs and Nest for Termination of Egg Laying of Red Junglefowl

    Importance of Tactile and Visual Stimuli of Eggs and Nest for Termination of Egg Laying of Red Junglefowl

    The Auk 112(2):483-488, 1995 IMPORTANCE OF TACTILE AND VISUAL STIMULI OF EGGS AND NEST FOR TERMINATION OF EGG LAYING OF RED JUNGLEFOWL THEO MEIJER Departmentof Ethology,University of BieIefeld,P.O. Box100131, 33501Bielefeld, Germany ABSTRACT.--Experimentswere conductedto separatethe influence of tactile and visual stimuli emanating from the nest or eggs on the development of incubation behavior, the terminationof egg laying, and the determinationof clutchsize. Red Junglefowl (Gallus gallus spadiceus)hens, whose eggswere left inside the nest (experiment 1), receivedboth tactile and visualinformation, remained in the nestbox longer,and stoppedlaying after eight days (or sixeggs). Sixteen or 17females incubated. Leaving only the firstegg in the nest(experiment 2) gavesimilar results. When the eggslaid were placedunder a wire-meshbasket (experiment 3) suchthat the hen couldsee but not touchthe accumulatingeggs, laying stopped two days (or one egg) later than in experiment1, and mosthens "incubated"on the empty nestuntil the nestbox wasremoved. Surprisingly, when eggswere continuallyremoved (experiment 4), hensalso incubated progressively more, stopped laying after two weeks(or nine eggs), and then sat on the empty nest for one or more days. Stimulation of the brood patch by the nest alone led to more incubationand to termination of egg laying. Visual stimuli alone providedby eggsaccelerated both processesand were sufficientfor one-half of the hens to maintainfull incubationbehavior. Red Junglefowl do not appearto judgeclutch size visually. Received9 December1993, accepted25 February1994. DURING THE BREEDINGSEASON, a female has to nest. The few experimentsby which tactile in- make two important "decisions":when to start formation coming from the brood patch was laying, and when to stop laying.

    Reproductive Ecology of Tibetan Eared Pheasant Crossoptilon Harmani in Scrub Environment, with Special Reference to the Effect of Food

    Ibis (2003), 145, 657–666 Blackwell Publishing Ltd. Reproductive ecology of Tibetan Eared Pheasant Crossoptilon harmani in scrub environment, with special reference to the effect of food XIN LU1* & GUANG-MEI ZHENG2 1Department of Zoology, College of Life Sciences, Wuhan University, Wuhan 430072, China 2Department of Ecology, College of Life Sciences, Beijing Normal University, Beijing 100875, China We studied the nesting ecology of two groups of the endangered Tibetan Eared Pheasants Crossoptilon harmani in scrub environments near Lhasa, Tibet, during 1996 and 1999–2001. One group received artificial food from a nunnery prior to incubation whereas the other fed on natural food. This difference in the birds’ nutritional history allowed us to assess the effects of food on reproduction. Laying occurred between mid-April and early June, with a peak at the end of April or early May. Eggs were laid around noon. Adult females produced one clutch per year. Clutch size averaged 7.4 eggs (4–11). Incubation lasted 24–25 days. We observed a higher nesting success (67.7%) than reported for other eared pheasants. Pro- visioning had no significant effect on the timing of clutch initiation or nesting success, and a weak effect on egg size and clutch size (explaining 8.2% and 9.1% of the observed variation, respectively). These results were attributed to the observation that the unprovisioned birds had not experienced local food shortage before laying, despite spending more time feeding and less time resting than the provisioned birds. Nest-site selection by the pheasants was non-random with respect to environmental variables. Rock-cavities with an entrance aver- aging 0.32 m2 in size and not deeper than 1.5 m were greatly preferred as nest-sites.

HYBRIDIZATION & ZOOGEOGRAPHIC PATTERNS IN PHEASANTS PAUL A. JOHNSGARD The purpose of this paper is to infonn members of the W.P.A. of an unusual scientific use of the extent and significance of hybridization among pheasants (tribe Phasianini in the proposed classification of Johnsgard~ 1973). This has occasionally occurred naturally, as for example between such locally sympatric species pairs as the kalij (Lophura leucol11elana) and the silver pheasant (L. nycthelnera), but usually occurs "'accidentally" in captive birds, especially in the absence of conspecific mates. Rarely has it been specifically planned for scientific purposes, such as for obtaining genetic, morphological, or biochemical information on hybrid haemoglobins (Brush. 1967), trans­ ferins (Crozier, 1967), or immunoelectrophoretic comparisons of blood sera (Sato, Ishi and HiraI, 1967). The literature has been summarized by Gray (1958), Delacour (1977), and Rutgers and Norris (1970). Some of these alleged hybrids, especially those not involving other Galliformes, were inadequately doculnented, and in a few cases such as a supposed hybrid between domestic fowl (Gallus gal/us) and the lyrebird (Menura novaehollandiae) can be discounted.

    Revision of Molt and Plumage

    The Auk 124(2):ART–XXX, 2007 © The American Ornithologists’ Union, 2007. Printed in USA. REVISION OF MOLT AND PLUMAGE TERMINOLOGY IN PTARMIGAN (PHASIANIDAE: LAGOPUS SPP.) BASED ON EVOLUTIONARY CONSIDERATIONS Peter Pyle1 The Institute for Bird Populations, P.O. Box 1346, Point Reyes Station, California 94956, USA Abstract.—By examining specimens of ptarmigan (Phasianidae: Lagopus spp.), I quantifi ed three discrete periods of molt and three plumages for each sex, confi rming the presence of a defi nitive presupplemental molt. A spring contour molt was signifi cantly later and more extensive in females than in males, a summer contour molt was signifi cantly earlier and more extensive in males than in females, and complete summer–fall wing and contour molts were statistically similar in timing between the sexes. Completeness of feather replacement, similarities between the sexes, and comparison of molts with those of related taxa indicate that the white winter plumage of ptarmigan should be considered the basic plumage, with shi s in hormonal and endocrinological cycles explaining diff erences in plumage coloration compared with those of other phasianids. Assignment of prealternate and pre- supplemental molts in ptarmigan necessitates the examination of molt evolution in Galloanseres. Using comparisons with Anserinae and Anatinae, I considered a novel interpretation: that molts in ptarmigan have evolved separately within each sex, and that the presupplemental and prealternate molts show sex-specifi c sequences within the defi nitive molt cycle.

  • Intergeneric Galliform Hybrids: a Review

    Intergeneric Galliform Hybrids: a Review

    INTERGENERIC GALLIFORM HYBRIDS : A REVIEW BY TONY J. PETERLE Henry Seebohm, in “The Birds of Siberia” (1901: Sol-502), makes this cogent observa- tion: “The subject of the interbreeding of nearly-allied birds in certain localities where their geographical ranges meet or overlap, and the almost identical subject of the existence of intermediate forms in the intervening district between the respective geographical ranges of nearly-allied birds, is one which has not yet received the attention which it deserves from ornithologists. The older brethren of the fraternity have always pooh-pooh’d any attempt to explain some of these complicated facts of nature by the theory of interbreeding, and have looked upon the suggestion that hybridisation was anything but an abnormal circumstance as one of the lamest modes of getting out of an ornithological difficulty.” The following sum- mary will show that interbreeding of galliform genera has often been observed: indeed that two wholly different intergeneric hybrids, one of the Old World, one of the New, have been recovered so often that they can hardly be considered ‘abnormal’ except in a very limited sense. The Old World hybrid referred to results from the crossing of the Blackcock (Lyvurus) and Capercaillie (Tetrao). DeWinton (1894: 448) said that “of all hybrids among birds in a wild state this one seems to be the most frequent.” Authors seem to be in agreement that the hybrid results principally, if not always, from the interbreeding of male Lyrurus with fe- male Tetreo in areas throughout which (a) extension of range is taking place, or (b) one or the other genus is rare, e.g., Scotland, where Tetrao has been introduced following extirpation (Millais, 1906: 55-56; DeWinton, 1894).

Washington, D.C. 20240 Dear Secretary Salazar: Pursuant to Section 4(b) of the Endangered Species Act (“ESA”), 16 U.S.C. §1533(b), Section 553(3) of the Administrative Procedure Act, 5 U.S.C. § 553(e), and 50 C.F.R. §424.14(a), The Center for Biological Diversity hereby formally petitions the Secretary of the Interior, through the United States Fish and Wildlife Service (“FWS”), to list either the U.S. population or Rocky Mountains population of the white-tailed ptarmigan (Lagopus leucura) as a threatened species and to designate critical habitat concurrent with listing. FWS has jurisdiction over this petition. This petition sets in motion a specific process, placing definite response requirements on FWS. Specifically, FWS must issue an initial finding as to whether the petition “presents substantial scientific or commercial information indicating that the petitioned action may be warranted.” 16 U.S.C. §1533(b)(3)(A). FWS must make this initial finding “[t]o the maximum extent practicable, within 90 days after receiving the petition.” Id. Petitioners need not demonstrate that listing is warranted, rather, petitioners must only present information demonstrating that such listing may be warranted. While petitioners believe that the best available science demonstrates that listing the white-tailed ptarmigan as threatened is in fact warranted, there can be no reasonable dispute that the available information indicates that listing the species as threatened may be warranted.

PEYTON, AND SIMON PANEAK2 ABSTRACT.Willow ptarmigan (Lagopus lagopus) migrate southward in autumn through Anaktuvuk Pass in the Brooks Range of Alaska and move northward in late winter to their principal nesting grounds on the arctic slope. In the morphologically homogeneous populationfour categories were distinguished-adult and juvenile males, adult and juvenile females-month by month at three localities. Adult males pre- ponderate in winter in their northern range, a large proportion ofjuveniie males winter at Anaktuvuk, and females preponderate in the southern wintering range.
