What to do about the north american invasion by the collared dove

Abstract: The attention of American ornithologists is drawn to the North American in- vasion of a renowned European invader, the Collared Dove (Streptopelia decaocto). After the experience obtained in Europe, several aspects can now be studied in North America, (1) how the spread across the continent is progressing, (2) how the local populations build up, (3) whether, by using a recent model, the rate of spatial progression of the invasion wave can be predicted, (4) how much, where and when pheno-genetic differentiation is generated, and (5) how it affects the local fauna. Americans have a unique opportunity to study the invasion of one of the best-known invaders, on their own ground, on the basis of extensive experience from Europe.

Histopathologic and Molecular Characterization of Sarcocystis calchasi Encephalitis in White-winged Doves (Zenaida asiatica) and Eurasian Collared Doves (Streptopelia decaocto), East-central Texas, USA, 2010–13

Abstract: Sarcocystis calchasi is a recently described apicomplexan parasite that causes encephalitis in avian hosts. We diagnosed one White-winged Dove (Zenaida asiatica) and two Eurasian Collared Doves (Streptopelia decaocto) in Texas, US, with a history of neurologic signs with protozoal encephalitis. On histologic examination, all three doves had moderate to severe meningoencephalitis characterized by large numbers of plasma cells, lymphocytes, and macrophages with gliosis and astrocytosis. Brain sections from two doves also contained numerous Mott cells. Protozoal schizonts with rosettes or clusters of individual merozoites consistent with Sarcocystis spp. were seen within areas of inflammation. Sarcocysts were also identified in the skeletal muscle of one dove. The PCR and sequencing of brain and skeletal muscle from two doves revealed 99% identity with S. calchasi. The presence of S. calchasi in fatal cases of encephalitis in doves in Texas suggests that the geographic and host ranges of S. calchasi...

Birds of Katima Mulilo town, Zambezi region, Namibia

Abstract: Large river valleys are usually characterized by high level of biodiversity, avian diversity. In Namibia, two towns are located in such valleys: Rundu on Okavango and Katima Malilo on Zambezi. To date, no quantitative studies on any components of biodiversity have been conducted in those towns. In January-May 2013, a total of 36 days were spent on quantitative studies of birds in Katima Mulilo town. The line transect and territory mapping methods were used in this study. A total of 122 resident (breeding), 9 visitors and 9 Palearctic migrants were recorded. The group of dominant species was composed of the following four species: Grey-headed Sparrow, Black-eyed Bulbul, Laughing Dove, and Blue Waxbill. They comprised together 42.5% of all birds. The group of subdominant species included: Rock Dove, Pied Crow, Cape Turtle-Dove, Red-eyed Dove, Southern Masked Weaver, Burchell’s Starling and Mourning Dove. Together they comprised 18.7%. The remaining 112 species comprised 38.8%. The most numerous feeding guilds were granivores (51.3%), frugivores and insectivores (each with c. 20%). Most birds (61.3%) nested in trees and shrubs. Katima Mulilo is probably the only town in whole southern Africa, where all four Streptopelia-doves are common species: Laughing, Cape Turtle, Red-eyed, and Mourning Dove. The only sparrow, which occurs in Katima Mulilo, is the Grey-headed Sparrow. Of special interest is the occurrence of dozen or so species which do not occur in other towns in Namibia, such as African Fish Eagle, Broad-billed Roller, Schalow’s Lorie, Trumpeter Hornbill, among others.

Eurasian Collared-Dove (Streptopelia decaocto) Usurps Nest of American Robins (Turdus migratorius)

Abstract: Interspecific nest usurpation was observed when a Eurasian Collared-Dove (Streptopelia decaocto) took over the nest of an American Robin (Turdus migratorius) in Plainview, Hale County, Texas in April 2014. The nest was constructed and occupied by an American Robin, briefly shared by a Eurasian Collared-Dove over a period of 3 days, and then aggressively taken over by the collared-dove. The collared-dove pair fledged two young in May 2014. This represents a first record of interspecific nest usurpation by Eurasian Collared-Dove. Interspecific nest piracy by this invasive species has implications for songbird conservation if the behavior proves to be frequent.

Complete genomic sequence of virulent pigeon paramyxovirus in laughing doves (streptopelia senegalensis) in kenya

Abstract: Following mass deaths of Laughing Doves (Streptopelia senegalensis) in different localities throughout Kenya, internal organs obtained during necropsy of two moribund birds were sampled and analyzed by next generation sequencing. We isolated the virulent strain of pigeon paramyxovirus type-1 (PPMV-1), PPMV1/Laughing Dove/Kenya/Isiolo/B2/2012, which had a characteristic fusion gene motif (110)GGRRQKRF(117). We obtained a partial full genome of 15,114 nucleotides. The phylogenetic relationship based on the fusion gene and genomic sequence grouped our isolate as class II genotype VI, a group of viruses commonly isolated from wild birds but potentially lethal to Chickens ( Gallus gallus domesticus ). The fusion gene isolate clustered with PPMV-I strains from pigeons (Columbidae) in Nigeria. The complete genome showed a basal and highly divergent lineage to American, European, and Asian strains, indicating a divergent evolutionary pathway. The isolated strain is highly virulent and apparently species-specific to Laughing Doves in Kenya. Risk of transmission of such a strain to poultry is potentially high whereas the cyclic epizootic in doves is a threat to conservation of wild Columbidae in Kenya.

Interspecific comparison of traffic noise effects on dove coo transmission in urban environments.

Abstract: Most previous studies concerning avian adaptation to anthropogenic noise have focused on songbirds, but few have focused on non-songbirds commonly found in urban environments such as doves. We conducted field playback-recording experiments on the perch-coos of five dove species, including four native Taiwan species (the spotted dove, Spilopelia chinensis, the oriental turtle-dove, Streptopelia orientalis, the red collared-dove, Streptopelia tranquebarica, and the emerald dove, Chalcophaps indica) and one species not native to Taiwan (the zebra dove, Geopelia striata) to evaluate the detection and recognition of dove coos in habitats with differing levels of traffic noise. Our results suggest that traffic noise has selected dominant urban species such as the spotted dove to temporally and spatially adjust cooing to reduce the masking effects of traffic noise and rare urban species such as the emerald dove to avoid areas of high traffic noise. Additionally, although the zebra dove had the highest coo frequency among the study species, its coos showed the highest detection value but not the highest recognition value. We conclude that traffic noise is an important factor in shaping the distribution of rare and dominant dove species in urban environments through its significant effects on coo transmission.

Presencia de la paloma turca (Streptopelia decaocto) en la ciudad de Lima, Perú

Abstract: We recorded the Eurasian Collared-Dove (Streptopelia decaocto) in Lima city, Peru. It is an exotic species to the American continent. Although it is of Eurasian origin, human activity has favoured its spread worldwide. In 1974 it was introduced as ornamental bird to the Bahamas and the Lesser Antilles and was dispersed throughout of the American continent. The Eurasian Collared-Dove has a high reproductive rate with up to three clutches per year and patterns of aggressive behaviour that have allowed it a signifi cant population increase and a successful dispersion.

Complete mitochondrial genome of the Spotted dove (Streptopelia chinensis).

Abstract: The Spotted dove (Streptopelia chinensis) is a member of the bird family Columbidae. In this study, we report the complete mitochondrial genome of this species. The mitochondrial genome of Spotted dove is a circular molecule of 16,966 bp in size and contains 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and one control region. The total base composition is 30.1% for A, 32.1% for C, 13.9% for G, and 23.9% for T. These data will be useful for the phylogenetic and population diversity analyses of birds, especially Columbidae species.

Case Report - Isolation of Yersinia (Pasteurella) pseudotuberculosis from the Palm Dove (Streptopelia senegalensis)

Abstract: SUMMARY Yersinia pseudotuberculosis was isolated from a sick Palm dove (Streptopelia senegalensis) picked up near a turkey farm in NirBanim, Israel. Clean birds and a guinea pig inoculated with the isolate died of the infection, or were killed in extremis. Y. pseudotuberculosis showing the same cultural characteristics as the original isolate was recovered from these animals. This is the first reported case of this infection from Israel.
