Co‐Occurrence and Occupancy of Mourning Doves and Eurasian Collared‐Doves

ABSTRACTUnderstanding how land cover and potential competition with invasive species shape patterns of occupancy, extirpation, and colonization of native species across a landscape can help target management for declining native populations. Mourning dove (Zenaida macroura) populations have declined throughout the United States from 1965–2015. The expansion of the Eurasian collared‐dove (Streptopelia decaocto), an introduced species with similar food preferences, may further threaten mourning dove populations. We analyzed data from 2009–2016 from a large‐scale monitoring program in the Western Great Plains of the United States in a 2‐species occupancy model to assess the effects of collared‐doves on mourning dove distributions, while accounting for imperfect detection and variation in land cover across the landscape. Mourning dove occupancy was stable or increasing across our study area, and despite overlap in resource use and co‐occurrence between mourning doves and Eurasian collared‐doves, we found no evidence that collared‐doves are extirpating mourning doves from preferred habitat during the breeding season. © 2020 The Wildlife Society.

Impact of Collared Dove Pigeons (Streptopelia decaocto) Age on some Hematological and Biochemical Parameters in Mosul City

The study conducted to determine the effect of differences of age on hematological and biochemical values of collared dove pigeons (Streptopelia decaocto) in Mosul city, Iraq. 28 healthy collared dove of 4 different age groups (7 birds of each group) 1 month, 3month, 6 months old as immature and 12 months old as mature pigeons were collected from local areas of Mosul city during May to August 2018. Total red blood cells (TES), packed cell volume (PCV), hemoglobin concentration (Hb), differential of white blood cells, serum total protein, cholesterol, triglycerides, uric acid and glucose were determined. The results showed fluctuations in parameters with different age groups. Mature birds had a significant increase (P ≤ 0.05) in PCV, Hb, Basophils, Monocytes, Lymphocytes, total protein and uric acid compared to immature birds. In the mature birds, there was a decrease in both heterophils, H / L ratio, total cholesterol, triglycerides and glucose when compared to immature birds. The conclusion from this study there is differences in blood parameters in collared dove pigeons according to the age advanced.

Complementarity of Nesting Ornithocomplexes in Urban Faunae (through the example of Melitopol, Southern Ukraine)

The results of the study of birds nesting in Melitopol conducted in 2011-2019 are presented. The distribution and correlation of bird species in urban biotopes based on a raster map with squares of 1x1 km is provided. There are 170 bird species registered in the city throughout the year, including 104 nesting species; over the last 50 years their number has increased by 69 species. Nesting ornithocomplex of the areas of the city with multi-storey buildings include 16 species, areas with individual buildings – 23 species, industrial sites - 21 species, green areas - 51 species, reed thickets - 27 species, agricultural landscapes - 24 species, floodplains - 9 species, floodplain meadows - 9 species. Over the last decades, birds of Corvidae family - Garrulus glandarius, Pica pica, Corvus monedula, C. frugilegus, C. cornix, C. corax - have inhabited the city and formed urbanized populations. Of the birds of prey - Falco tinnunculus and Athene noctua. The taxonomic and ecological structure of ornithocomplexes of the city is considered. The basis of ornithocomplexes are widespread species of synthantropes and dendrophylles. Introduced species (Phasianus colchicus) and invasive species (Streptopelia decaocto, Dendrocopos syriacus, D. minor, Phoenicurus ochruros, etc.) also inhabited the city. Representatives of the dendrophylic group predominate in the ecological structure of onitocomplexes of the studied area, which includes 47 species (45.2%), lymphophyllous group is represented by 26 species (25.0%), sclerophyllous – by 14 species (13.5%), campophyllous – by 9 species (8.7%), the limnophyllous-dendrophyllous group is represented by 1 species (0.9%), dendrophyllous-sclerophyllous – by 6 species (5.8%) and limnophyllous-sclerophyllous – by 1 species (0.9%). Complementarity of urban ornithocomplexes is high due to the syntantropic species - dendrophylles and sclerophylles.

Sex-specific responses to simulated territorial intrusions in the common cuckoo: a dual function of female acoustic signaling

The two-note call of the male common cuckoo (Cuculus canorus), the so-called “cu-coo”, is well known to people as a natural and cultural signal. However, the so-called “bubbling” call of the female cuckoo is almost unknown to most, and its function in the social organization of cuckoos remains understudied. We carried out a study of a possible intraspecific communication function of female bubbling calls, using playbacks to female cuckoos in their natural environment. Regarding vocal responses, both female and male cuckoos paid attention to the bubbling calls as they consistently responded acoustically by calling but did not so during control playbacks of collared dove (Streptopelia decaocto) calls. Accordingly, in about 63% of trials, females approached the loudspeaker closely and 81% uttered bubbling calls themselves during the experiment. These results are consistent with a function that the bubbling call plays a role in territorial signaling and defense among females. Male cuckoos also showed strong responses to playbacks of bubbling calls, as they approached the speaker and themselves called in 94% of playbacks; this is consistent with a scenario that they are interested in unfamiliar, new females in the area. Specifically, males approached the speaker repeatedly by flight, often flew around it and then perched on a tree, and uttered different call types beside the general “cu-coo” (e.g., quick “cu-cu-coo”, “gowk” call, and “guo” call). Our results represent an illustrative example that a simple female call may have multiple functions, as the cuckoo bubbling call advertises territory need for female cuckoos and attracts males.Significance statement Avian brood parasites lay their eggs in nests of other bird species, causing hosts to incubate, feed, and rear the parasitic offspring. Parasitic adult common cuckoos maintain a complex acoustic communication system, but female cuckoo calls are only beginning to be studied. The basic intraspecific functions of females’ sparrowhawk-like “bubbling calls” have not yet been characterized, whereas interspecifically, they use it for reducing antiparasitic attacks by their hosts. Our playback experiments with bubbling calls revealed that both female and male cuckoos responded acoustically to unfamiliar bubbling calls and more males than females approached the speaker, relative to control playbacks. We conclude that bubbling call has dual basic intraspecific functions: mate attraction, and territorial spacing.

Transformation of the community of nesting birds in the process of reorganization of the forest ecosystem into a park

Changes in nesting conditions cause a change in the number of individual species, ecological groups, and, consequently, the structure of the bird community. The purpose of the study is to analyze the possibilities and directions – the transformations of the communitys of nesting birds in the process of reorganization of the forest ecosystem into a park. The material was collected in the territory of one of the forest parks in the Kiev city. Forest is an mixed based on Quercus robur L., Carpinus betulus L., Acer platanoides L., Tilia cordata L., Fraxinus excelsior L. There are individual trees Pinus Syvestris L. The territory of the forest park have different degrees transformed, and includes anthropogenic landscapes and forests plots that have been preserved almost in their natural state. Studies were conducted in the nesting period (April-June) 2012–2017. For analysis average data were used. The number and distribution of the birds were determined by the method of counting on the transects, in the 3 model plots. There are 71 species of birds of 11 orders. Of these, 63 species are nesting. The number of nested species of communities in model plots does not depend on the gradient of anthropogenic transformation, but a average density of nesting birds decrease: 2.91±0.66→2.54±0.67→2.10±0.48 pairs / km of the transect. Nesting birds are distributed between 9 faunogenetic complexes. Of these, in each model plot is represented by 8. Dominated by birds of the European nemoral complex. On the gradient of habitat transformation, a change in the fauna-genetic structure of bird communities in the direction of increasing the proportion of birds of the European nemoral and European forest-steppe complexes, birds of desert-mountain and tropical groups. Boreal and ancient species are superseded. Strengthening the transformation in forest plots, the distribution of birds in community on the ecological groups does change not much. But when the forest ecosystem is replaced by a park ecosystem, the proportion of sclerophiles increases 3–4 times. In all communities is dominated by woody nesters bird. On the gradient of transformation, the number of species of the tree canopies nesters birds (from 21 to 18), ground nesters birds (from 6 to 0), species that use many types of nesting stations (from 4 to 1) are decreases; the number of bird species that nesting in the buildings increases from 0 to 6, and the number of alien species from 0 to 4 (Streptopelia decaocto, Dendrocopos syriacus, Phoenicurus ochruros, Serinus serinus). In the park ecosystems, a decrease in the species composition of woodpeckers, does not entail a significant decrease in the species composition and abundance of secondary hollows nesters birds. Birds of the synanthropic subpopulations are nesting in cavities in park buildings. Most of the indices show an equivalent ά-diversity of all bird communities. The β-diversity of breeding birds during the transformation of the forest ecosystem into a park is reduced by half. Ranked distribution curves of the abundance of species are indicate abrupt changes in the balance of dominance-diversity in communities when a transformation are in the forest ecosystem. The dominant species pressure high are give in community, its abundance is 2.2–2.7 times higher than the abundance of the second species by the abundance. In a slightly transformed forest, this indicator is 1.1 times. Ranked curves of relative abundance of species are a more sensitive index of community transformation than data of indices by the dominance and of species distribution. The introduction into the forest ecosystem of even a small number of anthropogenic structures leads to a significant increase in the relative abundance of synanthropic birds. In our study, in to 2 times. On the gradient of the transformation the absolute number of nesting species of the synanthropic birds increases gradually: 30–33–36; the obligate synanthropic species more stronger: 0–2–7; the index of community synanthropization increases 1.5 times: 0.63–0.72–0.92.

Third instars can be distinguished from second instar due to appearance of pleural seta on abdominal segment seventh to ninth.

ХРЕБЕТНІ ТВАРИНИ УРОЧИЩА "ФЕОФАНІЯ"

he local landscape Feofaniya is located on the outskirts of the Kyiv and represents communities of native oak wood with high density of ancient trees and hornbeam forest, steppe meadow, culture phytocenoses, cascade of ponds, stream. For the period 2012-2018 11 species of fish, 8 amphibians, 7 reptiles, 111 birds, 29 mammals were identified. Of these, 82.0 % of species are protected internationally, 8.9 % at the state level of the Ukraine, 12.6 % are regionally rare. In 81% of animal species, the reproductive site passes through the tract, and in half of them the whole life cycle. 19 % of the species composition of birds (Aves) are sedentary, 58 % arrive for nesting, 12 % for feeding, 9 % for wintering, 2 % for migratory (Regulus ignicapillus, Nucifraga caryocatactes). 82.8 % of mammals (Mammalia) are sedentary, 10.3 % are migratory (Pipistrellus nathusii, Pipistrellus pygmaeu, Nyctalus leisleri), 6.9 % with unexplained status (Neovison vison, Capreolus capreolus). The local landscape has 12 alien species. Carassius gibelio, Ctenopharyngodon idella, Hypophthalmichthys molitrix released into ponds with the purpose of stocking. Trachemys seripta elegans bring vacationers to the ponds. Pseudorasbora parva, Perccottus glenii, Streptopelia decaocto, Dendrocopos syriacus, Phoenicurus ochruros, Serinus serinus, Ondatra zibet, Pipistrellus kuhlii, Neovison vison penetrated the local landscape independently from neighboring biotopes. Thanks to biotechnical measures aimed at improving the living conditions of animals (protection of natural nests and the creation of artificial ones), hanging feeders in the winter, hanging shelters for daytime and wintering bats. The negative impact on the biotopes of Feofaniya from the side of recreants is somewhat leveled at the expense of educational work with vacationers. The most relevant propaganda work is aimed at educating correct behavior in nature, explaining the need to protect all plant and animal species, their biotopes, and explaining the consequences of disturbing the balance of sustainable development of ecosystems.

Evaluation of population parameters and biometric data of an Eurasian Collared Dove (Streptopelia decaocto Friv.) population in the Great Plain of Hungary

The Eurasian Collared Dove shows different patterns in density all over Hungary. In some cases, the population has decreased to a lower level, but there are habitats where the population remained stable. Several factors were taken into consideration during the evaluation of this phenomenon. These publications state that the increased urbanization of corvids, the lack of food sources, and the changes in nesting sites caused the decrease in numbers. During our research, we intend to contrast the differences in population structure of Collared Doves that differ from each other in the density of predators presented at nesting sites. As a first step, in this paper, numerous samples (n=118) were taken from a population that is less influenced by corvid species’ nest predation. Our prediction was that the population parameters remained at the level of 1980’s, in which the population of Eurasian Collared Dove has reached its maximum, according to further publications.
 During the evaluation process, our data were collected from hunting bags near Nyíregyháza. Results were compared with former publications. We stated that the population structure, such as age and gender distribution remained stable in the evaluated population. In addition, morphometric factors of the collected individuals were also measured, such as weight, wing length, 3rd primary feather, and tail length, which were compared with former surveys. During statistical tests no significant difference was revealed among population parameters, but there were significant differences between most of the morphometric data, (p>0.05).

New records of chewing lice (Phthiraptera: Amblycera, Ischnocera) from Egyptian pigeons and doves (Columbiformes), with description of one new species

Little information is available about the chewing lice of wild birds of Egypt, including common groups such as pigeons and doves (Columbiformes). Through this work, parasitic chewing lice of common columbiformes of Egypt were revised including new data. Three species of pigeons and doves (Streptopelia decaocto Frivaldszky 1838, Spilopelia senegalensis Linnaeus 1766 and Columba livia Gmelin 1789) were examined for chewing lice at three different localities. A total of 124 specimens of lice were collected. Nine species were identified from these samples; one species (Columbicola joudiae n. sp.) was considered a new species to science, six species were recorded from Egypt for the first time, and two species have been identified in Egypt before. Taxonomic and ecological remarks for all identified chewing lice samples are provided along with known and local hosts, measurements and material examined. Description and images of the new species are also provided.

The decline of the Turtle Dove: Dietary associations with body condition and competition with other columbids analysed using high-throughput sequencing.

Dietary changes linked to the availability of anthropogenic food resources can have complex implications for species and ecosystems, especially when species are in decline. Here, we use recently developed primers targeting the ITS2 region of plants to characterize diet from faecal samples of four UK columbids, with particular focus on the European turtle dove (Streptopelia turtur), a rapidly declining obligate granivore. We examine dietary overlap between species (potential competition), associations with body condition in turtle doves and spatiotemporal variation in diet. We identified 143 taxonomic units, of which we classified 55% to species, another 34% to genus and the remaining 11% to family. We found significant dietary overlap between all columbid species, with the highest between turtle doves and stock doves (Columba oenas), then between turtle doves and woodpigeons (Columba palumbus). The lowest overlap was between woodpigeons and collared doves (Streptopelia decaocto). We show considerable change in columbid diets compared to previous studies, probably reflecting opportunistic foraging behaviour by columbids within a highly anthropogenically modified landscape, although our data for nonturtle doves should be considered preliminary. Nestling turtle doves in better condition had a higher dietary proportion of taxonomic units from natural arable plant species and a lower proportion of taxonomic units from anthropogenic food resources such as garden bird seed mixes and brassicas. This suggests that breeding ground conservation strategies for turtle doves should include provision of anthropogenic seeds for adults early in the breeding season, coupled with habitat rich in accessible seeds from arable plants once chicks have hatched.

Evidence of cryptic species in the genus Tinaminyssus (Acari: Rhinonyssidae) based on morphometrical and molecular data.

The study of cryptic species allows to describe and to understand biodiversity, and the evolutionary processes shaping it. Mites of the family Rhinonyssidae are permanent parasites of the nasal cavities of birds, currently including about 500 described species and 12 genera. Here, we tested the hypothesis that mites from five populations of the genus Tinaminyssus-three isolated from European turtle doves (Streptopelia turtur), and two from Eurasian collared doves (Streptopelia decaocto; Aves: Columbiformes)-are, in fact, two cryptic species inhabiting different hosts. First, we performed a morphometrical study on 16 traits. Then, we used the ITS1-5.8S rDNA-ITS2 nuclear region (ITS region), and a fragment of the mitochondrial cytochrome c-oxidase 1 (COI) to carry out phylogenetic and species delimitation analyses on Tinaminyssus species. Morphological analyses revealed a lack of biometric differentiation among Tinaminyssus populations from the two host species. However, molecular analyses indicated a high degree of genetic differentiation between populations of Tinaminyssus sp. from S. turtur and S. decaocto. Overall, results show that they can be considered as different cryptic species, suggesting a case of evolutionary stasis, likely because of the anatomical similarity between closely-related bird host species.
