Listing Proposal for Mccown's Longspur
Listing Proposal for McCown’s Longspur (Rhynchophanes mccownii) in Nebraska Photo by Shawn Billerman Prepared by Melissa J. Panella and Joel G. Jorgensen Nebraska Game and Parks Commission Lincoln, Nebraska April 2018 Introduction The Nebraska Game and Parks Commission (hereafter, Commission) is authorized under the Nebraska Nongame and Endangered Species Conservation Act (NESCA; Neb. Rev. Stat. § 37-801 to 37-811) to determine what species should be placed on the list of threatened or endangered species maintained under the act. Species that are listed as threatened or endangered federally are automatically placed on the state’s list of threatened or endangered species; however, there are additional unlisted species whose continued existence within our state is at- risk and who are candidates for state listing. The Commission is obligated to conduct a review of species when monitoring data or emerging issues indicate concern. In 2017, Commission staff undertook a review of the state’s wildlife, including plants, to determine whether any species warranted placement on the list or whether any species currently listed as threated or endangered should be removed from the list. The last full review and revision of the list occurred in 2000. The purpose of the current statewide review is to maintain an accurate list of threatened and endangered species, based on the best information available, to help the Commission complete its mission of effectively conserving the wildlife resources of Nebraska. Over the last several months, Wildlife Division staff received input from species’ experts, conducted extensive literature reviews, and coordinated with the Commission’s Fisheries and Planning and Programming divisions to develop a list of species to consider for listing action. -

Recent Establishments and Extinctions of Northern Gannet Morus Bassanus Colonies in North Norway, 1995-2008
Recent establishments and extinctions of Northern Gannet Morus bassanus colonies in North Norway, 1995-2008 Robert T. Barrett Barrett, R.T. 2008. Recent establishments and extinctions of Northern Gannet Morus bassanus colonies in North Norway, 1995-2008. – Ornis Norvegica 31: 172-182. Since the last published review of the development of the Northern Gannet Morus bassanus population in Norway (Barrett & Folkestad 1996), there has been a general increase in numbers breeding in North Norway from ca. 2200 occupied nests in 1995 to ca. 2700 in 2008. In Lofoten and Vesterålen, however, numbers have decreased from 1500 occupied nests in 1989 to 500 in 2008, and what were the two largest colonies on Skarvklakken and Hovsflesa have been abandoned. Small colonies have, in the meantime, been established in the region, but these are all characteristically unstable. A new colony established in Troms in 2001 increased to 400 occupied sites in 2007, but the population dropped to 326 in 2008. Harassment by White-tailed eagles Haliaeetus albicilla is mooted as the main cause of the decline in Lofoten and Vesterålen. Robert T.

Braz J Vet Parasitol 2020; 29(3): e003920. https://doi.org/10.1590/S1984-29612020049 Abstract The Neotropic cormorant Nannopterum (Phalacrocorax) brasilianus (Suliformes: Phalacrocoracidae) is widely distributed in Central and South America. In Chile, information about parasites for this species is limited to helminths and nematodes, and little is known about other parasite groups. This study documents the parasitic fauna present in 80 Neotropic cormorants’ carcasses collected from 2001 to 2008 in Antofagasta, Biobío, and Ñuble regions. Birds were externally inspected for ectoparasites and necropsies were performed to examine digestive and respiratory organs in search of endoparasites. -
Mccown's Longspur (Rhynchophanes Mccownii)
McCown’s Longspur (Rhynchophanes mccownii ) A Species Conservation Assessment for The Nebraska Natural Legacy Project Prepared by Melissa J. Panella Nebraska Game and Parks Commission Wildlife Division November 2012 The mission of the Nebraska Natural Legacy Project is to implement a blueprint for conserving Nebraska’s flora, fauna and natural habitats through the proactive, voluntary conservation actions of partners, communities and individuals. Purpose The primary goal in development of at-risk species conservation assessments is to compile biological and ecological information that may assist conservation practitioners in making decisions regarding the conservation of species of interest. The Nebraska Natural Legacy Project recognizes the McCown’s Longspur ( Rhynchophanes mccownii ) as a Tier I at- risk species. Some general management recommendations are made here regarding the McCown’s Longspur (MCLO); however, conservation practitioners will need to use professional judgment to make specific management decisions based on objectives, location, and a multitude of variables. This resource was designed to share available knowledge of MCLO that will aid in the decision-making process or in identifying research needs for the benefit of the species. Species conservation assessments should not be stagnant documents but rather will need to be updated as new scientific information becomes available. The Nebraska Natural Legacy Project focuses efforts in the state’s Biologically Unique Landscapes (BULs), but it is recommended that whenever -
Discovery of a Relict Lineage and Monotypic Family of Passerine Birds
Discovery of a relict lineage and monotypic family of passerine birds Based on a comprehensive molecular dataset of passerines birds we identified a branch with a single species, the Spotted Wren-babbler Spelaeornis formosus. We suggest that this represents a relict lineage, which we propose should be placed in its own family, Elachuridae. The scientific name Elachura formosa should be used. We analysed of one of the most comprehensive datasets to date of the largest passerine bird clade, Passerida, which comprises c. 36% of the World’s c. 10,500 bird species. We identified 10 primary branches in the tree. One of these primary branches was made up of a single species, the Spotted Wren-Babbler Spelaeornis formosus, which is a small Wren-like bird that occurs in mountains from the eastern Himalayas to southeast China. This species apparently represents an old branch in the large passerine tree, without any close living relatives. There have surely been other relatives on this branch, which have gone extinct. The fact that it resembles wren-babblers and wrens in appearance is either due to pure chance or to convergent evolution, which may result in similar appearances in unrelated species that live in similar environments. We proposed the new family name Elachuridae for this single species. We also suggested that the scientific name Elachura formosa should be used, and the English name be changed to Elachura, to highlight its distinctness.

Phylogenetic Patterns of Size and Shape of the Nasal Gland Depression in Phalacrocoracidae
PHYLOGENETIC PATTERNS OF SIZE AND SHAPE OF THE NASAL GLAND DEPRESSION IN PHALACROCORACIDAE DOUGLAS SIEGEL-CAUSEY Museumof NaturalHistory and Department of Systematicsand Ecology, University of Kansas, Lawrence, Kansas 66045-2454 USA ABSTRACT.--Nasalglands in Pelecaniformesare situatedwithin the orbit in closelyfitting depressions.Generally, the depressionsare bilobedand small,but in Phalacrocoracidaethey are more diversein shapeand size.

21 Sep 2018 Lists of Victims and Hosts of the Parasitic
version: 21 Sep 2018 Lists of victims and hosts of the parasitic cowbirds (Molothrus). Peter E. Lowther, Field Museum Brood parasitism is an awkward term to describe an interaction between two species in which, as in predator-prey relationships, one species gains at the expense of the other. Brood parasites "prey" upon parental care. Victimized species usually have reduced breeding success, partly because of the additional cost of caring for alien eggs and young, and partly because of the behavior of brood parasites (both adults and young) which may directly and adversely affect the survival of the victim's own eggs or young. About 1% of all bird species, among 7 families, are brood parasites. The 5 species of brood parasitic “cowbirds” are currently all treated as members of the genus Molothrus. Host selection is an active process. Not all species co-occurring with brood parasites are equally likely to be selected nor are they of equal quality as hosts. Rather, to varying degrees, brood parasites are specialized for certain categories of hosts. Brood parasites may rely on a single host species to rear their young or may distribute their eggs among many species, seemingly without regard to any characteristics of potential hosts. Lists of species are not the best means to describe interactions between a brood parasitic species and its hosts. Such lists do not necessarily reflect the taxonomy used by the brood parasites themselves nor do they accurately reflect the complex interactions within bird communities (see Ortega 1998: 183-184). Host lists do, however, offer some insight into the process of host selection and do emphasize the wide variety of features than can impact on host selection. -

Plumage and sexual maturation in the Great Frigatebird Fregata minor in the Galapagos Islands. Marine Ornithology 34: 51–59. The adaptive significance of distinctive immature plumages and protracted sexual and plumage maturation in birds remains controversial. This study aimed to establish the pattern of plumage maturation and the age at first breeding in the Great Frigatebird Fregata minor in the Galapagos Islands. We found that Great Frigatebirds attain full adult plumage at eight to nine years for females and 10 to 11 years for males and that they rarely attempted to breed before acquiring full adult plumage. The younger males succeeded only at attracting a mate, and males and females both bred at the age of nine years when their plumage was nearly completely adult. Although sexual maturity was reached as early as nine years, strong competition for nest-sites may further delay first reproduction. We discuss our findings in light of the several hypotheses for explaining delayed plumage maturation in birds, concluding that slow sexual and plumage maturation in the Great Frigatebird, and perhaps among all frigatebirds, may result from moult energetic constraints during the subadult stage.
