Predation by Gray Catbird on Brown Thrasher Eggs
March 2004 Notes 101 PREDATION BY GRAY CATBIRD ON BROWN THRASHER EGGS JAMES W. RIVERS* AND BRETT K. SANDERCOCK Kansas Cooperative Fish and Wildlife Research Unit, Division of Biology, Kansas State University, Manhattan, KS 66506 (JWR) Division of Biology, Kansas State University, Manhattan, KS 66506 (BKS) Present address of JWR: Department of Ecology, Evolution, and Marine Biology, University of California, Santa Barbara, CA 93106 *Correspondent: [email protected] ABSTRACT The gray catbird (Dumetella carolinensis) has been documented visiting and breaking the eggs of arti®cial nests, but the implications of such observations are unclear because there is little cost in depredating an undefended nest. During the summer of 2001 at Konza Prairie Bio- logical Station, Kansas, we videotaped a gray catbird that broke and consumed at least 1 egg in a brown thrasher (Toxostoma rufum) nest. Our observation was consistent with egg predation because the catbird consumed the contents of the damaged egg after breaking it. The large difference in body mass suggests that a catbird (37 g) destroying eggs in a thrasher (69 g) nest might risk injury if caught in the act of predation and might explain why egg predation by catbirds has been poorly documented. Our observation indicated that the catbird should be considered as an egg predator of natural nests and that single-egg predation of songbird nests should not be attributed to egg removal by female brown-headed cowbirds (Molothrus ater) without additional evidence. RESUMEN El paÂjaro gato gris (Dumetella carolinensis) ha sido documentado visitando y rompien- do los huevos de nidos arti®ciales, pero las implicaciones de dichas observaciones no son claras porque hay poco costo por depredar un nido sin defensa. -
Cross-Temporal Analysis of Genetic Diversity in the Endangered Medium Tree Finch (Camarhynchus Pauper) and Closely Related Darwin’S Finches
Cross-Temporal Analysis of Genetic Diversity in the Endangered Medium Tree Finch (Camarhynchus pauper) and Closely Related Darwin’s Finches By Colleen Metzger B.S., Juniata College, 2009 A thesis submitted to the Graduate School of the University of Cincinnati Department of Biological Sciences In partial fulfillment of the requirements For the degree of Master of Science Committee Chair: Kenneth Petren, Ph.D. November 2012 Abstract Natural history collections can provide a direct view of past genotypes, which allows greater insight into evolutionary processes that are relevant for conservation and management. However, few studies have used broad surveys of multilocus genotypes from the past to address the wide range of processes that can affect conservation planning of a species today. Therefore, we assessed the history and status of the critically endangered medium tree finch, Camarhynchus pauper, an endemic finch of the Galápagos Islands. Using ancient DNA techniques, we quantified cross-temporal genetic change for 16 microsatellite loci in this species and its relatives. We tested the hypothesis that C. pauper has undergone a recent reduction in population size and loss of genetic diversity, and evaluated the hypothesis that C. pauper is genetically distinct from its two closest relatives, C. parvulus and C. psittacula. We assessed whether decline in C. pauper has led to increased hybridization with other species and evaluated a long-standing hypothesis of its origin from C. psittacula on another island using genetic distances, assignment tests, and migration analyses. Genetic diversity declined significantly in C. pauper over time, and several other tree finch populations showed similar losses of genetic diversity. -

Egg Investment Strategies Adopted by a Desertic Passerine, the Saxaul
Bao et al. Avian Res (2020) 11:15 https://doi.org/10.1186/s40657-020-00201-0 Avian Research RESEARCH Open Access Egg investment strategies adopted by a desertic passerine, the Saxaul Sparrow (Passer ammodendri) Xinkang Bao1* , Wei Zhao1, Fangqing Liu2, Jianliang Li1 and Donghui Ma1 Abstract Background: As one of the reproductive strategies adopted by bird species, variation in investment in egg produc- tion and its infuencing factors are important and well-studied subjects. Intraclutch changes in egg size associated with laying order may refect a strategy of “brood survival” or “brood reduction” adopted by female birds in diferent situations. Methods: We conducted feld studies on the breeding parameters of the Saxaul Sparrow (Passer ammodendri) in Gansu Province, China from 2010 to 2017, to clarify the factors afecting the egg investment and reproductive perfor- mance of this passerine species. Results: Our results revealed signifcant diferences in clutch size, egg size and the fedging rate between the frst and second brood of Saxaul Sparrows and suggested that this typical desert species allocates more breeding resources to the more favourable second brood period, leading to greater reproductive output. Female body size pre- sented a positive relationship with egg size, and male body size presented positive relationships with clutch size and hatchability. The females that started their clutches later laid more eggs, and hatchability and the fedging rate also increased with a later laying date in the frst brood period. With successive eggs laid within the 5-egg clutches (the most frequent clutch size), egg size increased for the frst three eggs and then signifcantly decreased. -

BORNEO: Bristleheads, Broadbills, Barbets, Bulbuls, Bee-Eaters, Babblers, and a Whole Lot More
BORNEO: Bristleheads, Broadbills, Barbets, Bulbuls, Bee-eaters, Babblers, and a whole lot more A Tropical Birding Set Departure July 1-16, 2018 Guide: Ken Behrens All photos by Ken Behrens TOUR SUMMARY Borneo lies in one of the biologically richest areas on Earth – the Asian equivalent of Costa Rica or Ecuador. It holds many widespread Asian birds, plus a diverse set of birds that are restricted to the Sunda region (southern Thailand, peninsular Malaysia, Sumatra, Java, and Borneo), and dozens of its own endemic birds and mammals. For family listing birders, the Bornean Bristlehead, which makes up its own family, and is endemic to the island, is the top target. For most other visitors, Orangutan, the only great ape found in Asia, is the creature that they most want to see. But those two species just hint at the wonders held by this mysterious island, which is rich in bulbuls, babblers, treeshrews, squirrels, kingfishers, hornbills, pittas, and much more. Although there has been rampant environmental destruction on Borneo, mainly due to the creation of oil palm plantations, there are still extensive forested areas left, and the Malaysian state of Sabah, at the northern end of the island, seems to be trying hard to preserve its biological heritage. Ecotourism is a big part of this conservation effort, and Sabah has developed an excellent tourist infrastructure, with comfortable lodges, efficient transport companies, many protected areas, and decent roads and airports. So with good infrastructure, and remarkable biological diversity, including many marquee species like Orangutan, several pittas and a whole Borneo: Bristleheads and Broadbills July 1-16, 2018 range of hornbills, Sabah stands out as one of the most attractive destinations on Earth for a travelling birder or naturalist. -
Partridges, Quails, Pheasants and Turkeys Phasianidae Vigors, 1825: Zoological Journal 2: 402 – Type Genus Phasianus Linnaeus, 1758

Johnsgard (1986) synthesised available data, came up with similar groupings of taxa, and produced a dendrogram indicating that turkeys (Meleagridinae) were the most primitive (outside Cracidae and Megapodiidae), with grouse (Tetraoninae), guineafowl (Numidinae), New World quails (Odontophorinae) and pheasants and kin (Phasianinae) successively more derived. Genetic evidence (DNA-hybridisation data) provided by Sibley & Ahlquist (1990) suggested Odontophorinae were the most basal phasianoids and guineafowl the next most basal group. A basal position of the New World quails among phasianoids has been supported by other genetic data (Kimball et al. 1999, Armstrong et al. 2001). A recent analysis based on morphological characters (Dyke et al. 2003) found support for megapodes as the most basal group in the order, then Cracidae, then Phasianidoidea, and within the latter, Numididae the most basal group. In contrast to the above genetic-based analyses, Dyke et al. (2003) found the Odontophorinae to be the most derived group within the order. A recent analysis using both mitochondrial ND2 and cytochrome-b DNA sequences, however, reinforces the basal position of the Odontophorinae (Pereira & Baker 2006). Here we follow a consensus of the above works and place Odontophorinae basal in the phasianids. Worthy & Holdaway (2002) considered that Cheeseman’s (1891) second-hand record of megapodes from Raoul Island, Kermadec Group, before the 1870 volcanic eruption has veracity. -

Gesamteindruck Eine unserer schönsten Reisen mit Albatros Tours. Dies ist vor allem Sophoan Sanh zu danken, die die Reise touristisch organisiert und ornithologisch durchgeführt hat. Mit ihrer herzlichen Art hat sie sofort unsere Herzen erobert. Unterbringung und Verpflegung waren sorgfältig ausgewählt, die Tagesabläufe gut geplant. Notwendige Anpassungen an die physischen Möglichkeiten der immerhin älteren Teilnehmer und an die örtlichen Gegebenheiten wurden von Sophoan umsichtig und geräuschlos vorgenommen. Das Essen war sehr gut, ortstypisch, schmackhaft und verträglich. Die Früchte der Saison wurden probiert. Sophoan hat sie immer wieder auf den lokalen Märkten gekauft und herbeigeschleppt. Die abendliche Diskussion der Beobachtungsliste war stets mit der Übergabe der Ziel- Arten für den nächsten Tag verbunden. Wir konnten uns also noch einmal darauf vorbereiten, wonach am nächsten Beobachtungsort Ausschau zu halten war. Sophoan hat in jahrelanger praktischer Tätigkeit ein umfangreiches ornithologisches Wissen und Beobachtungstaktik aufgebaut. Ihre Kenntnisse der Vogelstimmen sind exzellent. Sie bringt eine umfassende Stimmensammlung zum Einsatz, was die Voraussetzung dafür war, dass sich manche Vögel überhaupt zeigten. -

Mating System and Social Behavior of Rusty Blackbirds On
MATING SYSTEM AND SOCIAL BEHAVIOR OF RUSTY BLACKBIRDS ON YUKON FLATS NATIONAL WILDLIFE REFUGE By April Harding Scurr A Thesis Presented to The Faculty of Humboldt State University In Partial Fulfillment of the Requirements for the Degree Master of Science in Natural Resources: Wildlife Committee Membership Dr. T. Luke George, Committee Chair Dr. Mark Colwell, Committee Member Dr. Susan Sharbaugh, Committee Member Dr. Rob Van Kirk, Graduate Coordinator May 2013 ABSTRACT THE MATING SYSTEM AND SOCIAL BEHAVIOR OF RUSTY BLACKBIRDS ON YUKON FLATS NATIONAL WILDLIFE REFUGE April Harding Scurr Many aspects of the breeding biology of the rapidly declining Rusty Blackbird (Euphagus carolinus) are unknown. I used behavioral observations and genetic analyses to gain a better understanding of their mating system, on Yukon Flats National Wildlife Refuge, Alaska, USA. Four polymorphic microsatellites developed for other avian species (QmAAT21, QmAAT37, Aph54, and Mp2-43) were used to assess rates of extra- pair paternity, polyandry, and egg dumping. Behavioral observations were employed to identify the social mating system and parental nest investment in relation to genetic contributions. In contrast to previous studies, my results indicate that male Rusty Blackbirds are not socially monogamous; over 15% of nests belonged to polygynous males. There was no evidence of polyandry or egg dumping, but extra-pair paternity (EPP) occurred in ≥ 33% of nests. There was no correlation between the proportion of young that a male sired in a nest and either feeding rate or nest defense. Further studies are needed to investigate the role of environmental and social factors on mating systems and the rates of polygamy and EPP in Rusty Blackbirds. -
The Mysteries of Bird Migration – Still Much to Be Learnt
The mysteries of bird migration – still much to be learnt Franz Bairlein ABSTRACT Bird ringing has unveiled many mysteries of avian migrations, notably routes and destinations. However, there is still much to be explored by the use of ringing and other marking techniques. Satellite tracking, geolocation and global positioning systems are new tools, as well as particular chemical and molecular markers which appear to be very useful in the study of bird migration by delineating origin of birds and connectivity between breeding and non-breeding grounds. Understanding of bird migrations also gained much from captive studies about the internal mechanisms in the control of bird migration, but we still lack knowledge about external factors, such as food availability, weather, competitors, parasites or diseases.This paper summarises ongoing studies on Northern Wheatears Oenanthe oenanthe to illustrate the benefit of such an integrated approach. Future migration research must aim much more at comparative research and a more integrated approach at various spatial and temporal scales, and linking various sub-disciplines. It is also important to realise that migration is only one part of the life-cycle of a migrating species.Thus, linking migration and breeding is another future challenge, for both basic science and conservation of migratory birds. or centuries, the seasonal arrival and The study of bird migration by ringing departure of bird species to and from Our knowledge of bird migration improved Ftheir breeding grounds remained a dramatically with the development of bird mystery.
