Trichomonad parasite infection in four species of Columbidae in the UK

Abstract: Trichomonas gallinae is an emerging pathogen in wild birds, linked to recent declines in finch (Fringillidae) populations across Europe. Globally, the main hosts for this parasite are species of Columbidae (doves and pigeons); here we carry out the first investigation into the presence and incidence of Trichomonas in four species of Columbidae in the UK, through live sampling of wild-caught birds and subsequent PCR. We report the first known UK cases of Trichomonas infection in 86% of European Turtle Doves Streptopelia turtur sampled, along with 86% of Eurasian Collared Doves Streptopelia decaocto, 47% of Woodpigeons Columba palumbus and 40% of Stock Doves Columba oenas. Birds were more likely to be infected if the farm provided supplementary food for gamebirds. We found three strains of T. gallinae and one strain clustering within the Trichomonas tenax clade, not previously associated with avian hosts in the UK. One T. gallinae strain was identical at the ITS/5.8S/ITS2 ribosomal region to that responsible for the finch trichomonosis epizootic. We highlight the importance of increasing our knowledge of the diversity and ecological implications of Trichomonas parasites in order further to understand the sub-clinical impacts of parasite infection.

Experimental infection of Eurasian collared-dove (Streptopelia decaocto) with West Nile virus.

Abstract: The Eurasian collared-dove (Streptopelia decaocto) has recently experienced a population explosion in North America. It is frequently infected with West Nile virus (WNV). To test the hypothesis that the Eurasian collared-dove is competent to transmit WNV, we experimentally infected two cohorts of doves with two different strains of WNV, CO08, and NY99, respectively. Both virus strains induced a low-level viremia, capable of infecting a small fraction of vector mosquitoes. We suggest that the Eurasian collared-dove plays a relatively insignificant role as an amplifying host for WNV, but it may be important where it is locally abundant.

Effet de l'urbanisation sur le phénotype de la Tourterelle turque (Streptopelia decaocto) dans le Nord-Est Algérien The effect of urbanization on the phenotype of the Collared Dove (Streptopelia decaocto) in northeastern Algeria

Abstract: Numerous species were adapted to humans, especially invasive species associated to humans in towns and cities. These adaptations to urban environments are expressed by changes in behaviour and physiology, reflecting phenotypic plasticity or evolution (Moller, 2008). Although the Collared Dove (Streptopelia decaocto) is one of the most common Columbidae species in the different Algerians environments during the recent years (Merabet et al. 2010, Belabed 2013), the data on its biometry are almost non existent. This work, conducted during 2011, in northeastern Algeria, aims to produce information on the effect of the degree of urbanization on the phenotype of Collared Doves adult in Annaba (extreme northeastern Algeria), based on their morphometric data. To do this, our methodology was to capture adult individuals in two different sites: one urban and one suburban, and measure the morphological parameters. The parameters that have been considered are : weight, height, width and length of the beak, length of culmen, collar, tarsus, stretched and bent wing, the fifth remix and finally the wing span. Our results show that there are significant differences between the individuals captured in both environments. Indeed, the collar, the stretched and bent wing and the wing span are more important for individuals in suburban site. Whereas, urban individuals show height and a larger bill length. Showing differences in adaptive flight and food, between the two sites. while urban individuals show a height and length of beak more important. This reflects differences in adaptive flight and food between the two sites.

Molecular classification of Pakistani collared dove through DNA barcoding

Abstract: Pakistan is bestowed by a diversified array of wild bird species including collared doves of which the taxonomy has been least studied and reported. DNA barcoding is a geno-taxonomic tool that has been used for characterization of bird species using mitochondrial cytochrome c oxidase I gene (COI). This study aimed to identify taxonomic order of Pakistani collared dove using DNA barcoding. Purposely herein, we present a phylogenetic analysis of Pakistani collared dove based on 650 base pairs of COI gene sequences. Analysis of phylogenetic tree revealed that Pakistani collared dove shared a common clade with Eurasian collared dove (Streptopelia decaocto) and African collared dove (Streptopelia roseogrisea) which indicated a super-species group in Streptopelia genus. This is the first report of molecular classification of Pakistani collared dove using DNA barcoding.

Mate reinforcement value and the pair bond in ring neck dove (Streptopelia risoria)

Abstract: During the breeding season, monogamous birds form partnerships characterized by preferential involvement in reproductive and parental behaviors with a mate. The breeding partnership is dependent on a ‘pair bond’, an adhesive force that promotes prolonged affiliation and behavioral cooperation between two birds. Here we propose that the adhesive force of the pair bond is at least partially the result of the acquired reinforcement value of the mate. If the mate becomes a reinforcer during courtship then through classical conditioning principles the mate will reinforce affiliative behavior evident in pair-bonded birds. The present experiments were designed to determine whether the pair-bonded mate of ring neck dove (Streptopelia risoria) acquire reinforcement value during the reproductive cycle. Mate reinforcement value was assessed using a conditioned place preference paradigm in which the mate was paired with a visually distinct context and a second distinct context was paired with social isolation (Experiment 1) or an unfamiliar bird of the opposite sex (Experiment 2). Both males and females preferred the context that had been paired with the mate to the context paired with social isolation or an unfamiliar dove. The results suggest that pair-bonded mates are stronger reinforcers than unfamiliar birds. Experiment 3 found that the preference for the mate context over the unfamiliar dove context was stronger during incubation than during courtship. The possible involvement of a classical conditioning process in the maintenance of the pair bond is discussed.

Hypodectes propus (Acarina: Hypoderatidae) in a rufous turtle dove, Streptopelia orientalis (Aves: Columbiformes), in Japan

Abstract: An adult male rufous turtle dove, Streptopelia (S.) orientalis (Aves: Columbiformes), was found dead in Yorii-machi Town, Osato District 369-1217, Saitama Prefecture, Japan, and subjected to necropsy. A large number of immobile hypopi (deutonymphs) of the hypoderatid mite, Hypodectes (H.) propus (Acarina: Hypoderatidae), were found individually encapsulated subcutaneously primarily in the adipose tissue. The mites were 1.43 mm in length and 0.44 mm in width on average, and had provoked mild inflammatory reactions that predominantly manifested as foamy macrophages and lymphoplasmocytes. PCR analysis using ribosomal DNA extracted from paraffin-blocked tissues produced a 240 bp band specific for hypoderatids. Based on the morphological features (distinct coxal apodemes, especially in the anterior portion) and PCR-based findings, the hypopi were identified as H. propus. To the best of our knowledge, this is the first case describing the subcutaneous mite H. propus in a rufous turtle dove, S. orientalis, in Japan. This study also highlights the use of paraffin blocks as a source of tissue DNA for molecular evaluation.

Breeding biology of Collared Dove (Streptopelia decaocto) in Khuzestan Province, Southwestern Iran

Abstract: This study carried out from April to Jun 2010. Breeding behaviour of Collared Dove started at 8 April with observation of nest building and finished at 9 June with flight of last fledgling. During the study period 19 nests with 38 eggs (mean of 2.0 eggs per nest) surveyed. In total, 60.5% of the eggs hatched and 60.9% of hatchlings reached near-fledgling stage, giving an overall breeding success of 36.8%. Mean nest productivity was 0.7 ± 1.0 fledglings per breeding pair and 1.2 ± 1.0 fledglings per successful pair. Breeding failure had a significant difference in the egg stage, chicks before18 days and chicks older than 18 days (p < 0.05). Nest parameters had not a significant effect on the breeding success. 46.7% nests were ravaged by birds, 26.7% – by mammals, 13.3% – by reptiles and 13.3% clutches and broods were lost owing to bad weather.

Occurrence and Seasonal Variation of the Avifauna at Domate Al- Jandal Lake, Al-Jouf Province of Saudi Arabia

Abstract: Forty six bird species belonging to 22 families and 12 orders were observed at Domate Al-Jandal lake during the study period (December 2010 to November 2011). Among these 11 species were resident, 10 species were resident migrant and 25 species were migrant. Highest occurrence was seen during winter with a peak in January when insectivorous birds were dominant. Common Moorhen (Gallinula chloropus), Little Grebe (Tachybaptus ruficollis) and Eurasian Collared Dove (Streptopelia decaocto) showed the highest occurrence whereas Cormorant (Phalacrocorax carbo), Common Shelduck (Tadorna tadorna) and White Stork (Ciconia ciconia) occurred less frequently. Suggestions were made on the bases of the results of the present study to increase the number of aquatic birds and also to promote eco-tourism.

Distribution And Daily Activity Of Collared Dove (Streptopelia Decaocto) In And Around Sikar (Rajasthan), India

Abstract: Collared Dove is native species of Asia and Europe. It is found in throughout the drier portions of the Indian Union. Collared Dove native to India, Sri Lanka and Myanmar. It is not migratory bird but it is strongly dispersive bird. Collared Dove lives in urban and rural areas, farmlands, parks, gardens, open fields and grain stores. Collared Dove preferred as roosting plant species like as Khejri (Prosopis cineraria) and Babool (Acacia nilotica) and also retires on them during the midday heat. It is found in abundant in the neighborhood of human habitations, and freely enters gardens and bungalow verandas. Collared Dove mainly feeds on spreading seeds on the ground, but also feed on buds, soft fruits and garbage. It is freely feeds near to human habitation. Collared Dove feeds on the ground in large flocks around farms and grain stores. It is gregarious species and flocks will form where there are food supplies such as grain (its main food) as well as seeds and shoots. Collared Dove drinks by sucking and dont need to put the head back to swallow. The breeding season of Collared Dove is in March to late October but breeding occurs throughout the year when abundant food is available, though only rarely in winter. Collared Dove preferred as nesting plant species like as Khejri (Prosopis cineraria), Kikar (Acacia nilotica) and Neem (Azardirecta indica). The maximum population was recorded during the rainy season i.e. the months of July, August and September. Maximum activities performed by the collared dove in the early morning to late morning (5.00 AM to 11.00 AM) and less activities performed in afternoon to evening (3.30 PM to 7.00 PM).
