However, little is known about how Received 23 October 2011 organisms respond to one of the most salient visual cues of risk: a dead conspecific. Here we show that Initial acceptance 16 January 2012 the sight of a dead conspecific is sufficient to induce alarm calling and subsequent risk-reducing Final acceptance 25 July 2012 behavioural modification in western scrub-jays, Aphelocoma californica, and is similar to the response Available online 27 August 2012 to a predator (a great horned owl, Bubo virginianus, model). Discovery of a dead conspecific elicits MS. number: A12-00867R vocalizations that are effective at attracting conspecifics, which then also vocalize, thereby resulting in a cacophonous aggregation. Presentations of prostrate dead conspecifics and predator mounts elicited Keywords: aggregations and hundreds of long-range communication vocalizations, while novel objects did not. In Aphelocoma californica contrast to presentations of prostrate dead conspecifics, presentations of a jay skin mounted in an bird upright, life-like pose elicited aggressive responses, suggesting the mounted scrub-jay was perceived to cacophonous aggregation cues of risk be alive and the prostrate jay was not. -

Spring in South Texas
SPRING IN SOUTH TEXAS MARCH 31–APRIL 9, 2019 Green Jay, Quinta Mazatlan, McAllen, Texas, April 5, 2019, Barry Zimmer LEADERS: BARRY ZIMMER & JACOB DRUCKER LIST COMPILED BY: BARRY ZIMMER VICTOR EMANUEL NATURE TOURS, INC. 2525 WALLINGWOOD DRIVE, SUITE 1003 AUSTIN, TEXAS 78746 WWW.VENTBIRD.COM SPRING IN SOUTH TEXAS MARCH 31–APRIL 9, 2019 By Barry Zimmer Once again, our Spring in South Texas tour had it all—virtually every South Texas specialty, wintering Whooping Cranes, plentiful migrants (both passerine and non- passerine), and rarities on several fronts. Our tour began with a brief outing to Tule Lake in north Corpus Christi prior to our first dinner. Almost immediately, we were met with a dozen or so Scissor-tailed Flycatchers lining a fence en route—what a welcoming party! Roseate Spoonbill, Crested Caracara, a very cooperative Long-billed Thrasher, and a group of close Cave Swallows rounded out the highlights. Strong north winds and unsettled weather throughout that day led us to believe that we might be in for big things ahead. The following day was indeed eventful. Although we had no big fallout in terms of numbers of individuals, the variety was excellent. Scouring migrant traps, bays, estuaries, coastal dunes, and other habitats, we tallied an astounding 133 species for the day. A dozen species of warblers included a stunningly yellow male Prothonotary, a very rare Prairie that foraged literally at our feet, two Yellow-throateds at arm’s-length, four Hooded Warblers, and 15 Northern Parulas among others. Tired of fighting headwinds, these birds barely acknowledged our presence, allowing unsurpassed studies. -

Molt and the Annual Cycle of the Chuck-Will's-Widow, Caprimulgus Carolinensis
THE AUK A QUARTERLY JOURNAL OF ORNITHOLOGY VoL. 88 JuLY 1971 No. 3 MOLT AND THE ANNUAL CYCLE OF THE CHUCK-WILL'S-WIDOW, CAPRIMULGUS CAROLINENSIS S•EVERT A. RO•WER TUE family Caprimulgidae consistsof about 73 speciesof nocturnal and crepuscularbirds commonly called nightjars from their persistent penetratingnocturnal calls. They are divided into. two subfamilies,the Chordeilinae,a group of 8 New World species,and the Caprimulginae,a group of approximately65 speciesoccurring in most of the warmer land areasof the world. The chordeilinesare largelycrepuscular in their habits, somespecies being active on overcastor, occasionally,sunny days; most of the caprimulginesare much more nocturnal than the chordeilines.The Chuck-will's-widow(Caprimulgus carolinensis) is the largestmember of its genus,which contains some 40. African, Eurasian,and New World species (Peters, 1940). It is a commonbreeding bird of the deciduousforests of the southern third of eastern North America, and winters largely in the Antilles, Central America,and the southernmostareas of eastern North America. The sequenceof molt has been describedfor several African and Eurasian caprimulgines(Verheyen, 1956; Stresemannand Stresemann, 1966) and partially describedfor the chordeilineCommon Nighthawk (Chordeilesminor) by Selander(1954). Someintriguing variations exist in the sequenceand timing of molts amongthe caprimulgiforms(Strese- mann and Stresemann,1966; Rohwer, MS on Phalaenoptilusnuttallii), and knowledgeof the sequenceand time of feather replacement for more caprimulgiforms,coupled -

Synonymies for Indigenous Hawaiian Bird Taxa
Part 2 - Drepaninines Click here for Part 1 - Non-Drepaninines The Birds of the Hawaiian Islands: Occurrence, History, Distribution, and Status Version 2 - 1 January 2017 Robert L. Pyle and Peter Pyle Synonymies for Indigenous Hawaiian Bird Taxa Intensive ornithological surveying by active collectors during the latter 1890s led to several classic publications at the turn of the century, each covering nearly all species and island forms of native Hawaiian birds (Wilson and Evans 1899, Rothschild (1900),schild 1900, Bryan 1901a, Henshaw (1902a), 1902a, Perkins (1903),1903). The related but diverse scientific names appearing in these publications comprised the basis for scientific nomenclature for the next half century, but in many cases were modified by later authors using modern techniques to reach a current nomenclature provided in the American Ornithologists’ Union (AOU) Check-List, and followed (for the most part) at this site. A few current AOU names are still controversial, and more changes will come in the future. Synonymies reflecting the history of taxonomic nomenclature are listed below for all endemic birds in the Hawaiian Islands. The heading for each taxon represents that used in this book, reflecting the name used by the AOU (1998), as changed in subsequent AOU Supplements, or, in a few cases, as modified here based on more recent work or on differing opinions on taxonomic ranking. Previously recognized names are listed and citations included for classic publications on taxonomy of Hawaiian birds, as well as significant papers that influenced the species nomenclature. We thank Storrs Olson for sharing with us his summarization on the taxonomy and naming of indigenous Hawaiian birds. -
Non-Native Trees Provide Habitat for Native Hawaiian Forest Birds
NON-NATIVE TREES PROVIDE HABITAT FOR NATIVE HAWAIIAN FOREST BIRDS By Peter J. Motyka A Thesis Submitted in Partial Fulfillment Of the Requirements for the Degree of Master of Science In Biology Northern Arizona University December 2016 Approved: Jeffrey T. Foster, Ph.D., Co-chair Tad C. Theimer, Ph. D., Co-chair Carol L. Chambers, Ph. D. ABSTRACT NON-NATIVE TREES PROVIDE HABITAT FOR NATIVE HAWAIIAN FOREST BIRDS PETER J. MOTYKA On the Hawaiian island of Maui, native forest birds occupy an area dominated by non- native plants that offers refuge from climate-limited diseases that threaten the birds’ persistence. This study documented the status of the bird populations and their ecology in this novel habitat. Using point-transect distance sampling, I surveyed for birds over five periods in 2013-2014 at 123 stations across the 20 km² Kula Forest Reserve (KFR). I documented abundance and densities for four native bird species: Maui ‘alauahio (Paroreomyza montana), ʻiʻiwi (Drepanis coccinea), ʻapapane (Himatione sanguinea), and Hawaiʻi ʻamakihi, (Chlorodrepanis virens), and three introduced bird species: Japanese white-eye (Zosterops japonicas), red-billed leiothrix (Leiothrix lutea), and house finch (Haemorhous mexicanus). I found that 1) native forest birds were as abundant as non-natives, 2) densities of native forest birds in the KFR were similar to those found in native forests, 3) native forest birds showed varying dependence on the structure of the habitats, with ʻiʻiwi and ‘alauahio densities 20 and 30 times greater in forest than in scrub, 4) Maui ‘alauahio foraged most often in non-native cape wattle, eucalyptus, and tropical ash, and nested most often in non-native Monterey cypress, Monterey pine, and eucalyptus. -
Corvids of Cañada
!!! ! CORVIDS OF CAÑADA COMMON RAVEN (Corvus corax) AMERICAN CROW (Corvus brachyrhyncos) YELLOW-BILLED MAGPIE (Pica nuttalli) STELLER’S JAY (Cyanocitta stelleri) WESTERN SCRUB-JAY Aphelocoma californica) Five of the ten California birds in the Family Corvidae are represented here at the Cañada de los Osos Ecological Reserve. Page 1 The Common Raven is the largest and can be found in the cold of the Arctic and the extreme heat of Death Valley. It has shown itself to be one of the most intelligent of all birds. It is a supreme predator and scavenger, quite sociable at certain times of the year and a devoted partner and parent with its mate. The American Crow is black, like the Raven, but noticeably smaller. Particularly in the fall, it may occur in huge foraging or roosting flocks. Crows can be a problem for farmers at times of the year and a best friend at other times, when crops are under attack from insects or when those insects are hiding in dried up leftovers such as mummified almonds. Crows know where those destructive navel orange worms are. Smaller birds do their best to harass crows because they recognize the threat they are to their eggs and young. Crows, ravens and magpies are important members of the highway clean-up crew when it comes to roadkills. The very attractive Yellow-billed Magpie tends to nest in loose colonies and forms larger flocks in late summer or fall. In the central valley of California, they can be a problem in almond and fruit orchards, but they also are adept at catching harmful insect pests. -
Diet of Breeding White-Throated and Black Swifts in Southern California
DIET OF BREEDING WHITE-THROATED AND BLACK SWIFTS IN SOUTHERN CALIFORNIA ALLISON D. RUDALEVIGE, DESSlE L. A. UNDERWOOD, and CHARLES T. COLLINS, Department of BiologicalSciences, California State University,Long Beach, California 90840 (current addressof Rudalevige:Biology Department, Universityof California,Riverside, California 92521) ABSTRACT: We analyzed the diet of nestling White-throated(Aeronautes saxatalis) and Black Swifts (Cypseloidesniger) in southern California. White- throatedSwifts fed their nestlingson bolusesof insectsmore taxonomicallydiverse, on average(over 50 arthropodfamilies represented), than did BlackSwifts (seven arthropodfamilies, primarfiy ants). In some casesWhite-throated Swift boluses containedprimarily one species,while other bolusesshowed more variation.In contrast,all BlackSwift samplescontained high numbersof wingedants with few individualsof other taxa. Our resultsprovide new informationon the White-throated Swift'sdiet and supportprevious studies of the BlackSwift. Swiftsare amongthe mostaerial of birds,spending most of the day on the wing in searchof their arthropodprey. Food itemsinclude a wide array of insectsand some ballooningspiders, all gatheredaloft in the air column (Lack and Owen 1955). The food habitsof a numberof speciesof swifts have been recorded(Collins 1968, Hespenheide1975, Lack and Owen 1955, Marfn 1999, Tarburton 1986, 1993), but there is stilllittle informa- tion availablefor others, even for some speciesthat are widespreadand common.Here we providedata on the prey sizeand compositionof food broughtto nestlingsof the White-throated(Aerona u tes saxa talis) and Black (Cypseloidesniger) Swifts in southernCalifornia. The White-throatedSwift is a commonresident that nestswidely in southernCalifornia, while the Black Swift is a local summerresident, migrating south in late August (Garrettand Dunn 1981, Foersterand Collins 1990). METHODS When feedingyoung, swifts of the subfamiliesApodinae and Chaeturinae return to the nest with a bolusof food in their mouths(Collins 1998). -
