We report two bird species with pigment anomalies, which were seen in Cali, Colombia in 2020. The individuals were, a female Shiny Cowbird (Molothrus bonariensis) with partial leucism, a female Ruddy Ground-Dove (Columbia talpacoti) with partial leucism and a young nestling of the same species, with albinism. The records reported here are the first of partial leucism and albinism for Columbia talpacoti and partial leucism for Molothrus bonariensis in Colombia.

Some bird species feed on external parasites, such as ticks and flies, on the body of mammals (hosts or clients). So called cleaner birds that occur in Brazil were reviewed recently, but gathering of significant new data indicates the need for an update and a brief reappraisal of such association. New records raise the number of known clients for some cleaning birds. The Southern Caracara (Caracara plancus) picks ticks on cattle, and the Black Caracara (Daptrius ater) picks ticks on capybaras. The Wattled Jacana (Jacana jacana) picks ticks, horseflies, arthropods and organic debris on capybaras, and tick-picking on capybaras by the Shiny Cowbird (Molothrus bonariensis) is substantiated by photographs. The Cattle Tyrant (Machetornis rixosa) deftly catches horseflies on capybaras, and these latter clients are recorded posing for the Giant Cowbird (Molothrus oryzivorus), which also pick parasites from the marsh deer. The Cattle Egret (Bubulcus ibis) definitely picks ticks directly on cattle. With the new records, some poorly documented or controversial issues in the literature are here confirmed, a hypothesis is validated, and a suggestion is invalidated.

Abstract Comparative studies of parasites in sympatric bird species have been generally scarce. Parasitic infection/transmission can be spread in a number of ways that suggests possible direct and indirect, horizontal transmission between avian hosts. In order to determine whether two sympatric icterids from Central and Southern Chile share their parasite fauna (ecto- and endoparasites), we examined parasites of 27 Shiny Cowbirds, Molothrus bonariensis, and 28 Austral Blackbirds, Curaeus curaeus, including individuals captured in the wild and carcasses. We found that Shiny Cowbirds were infected with the chewing lice Brueelia bonariensis, Philopterus sp. 1, the feather mites Amerodectes molothrus, Proctophyllodes spp. (species 1 and 2), and the helminths Mediorhynchus papillosus, Plagiorhynchus sp., Dispharynx nasuta and Tetrameres paucispina, while Austral Blackbirds had the chewing lice Myrsidea sp., Philopterus sp. 2, the feather mites Proctophyllodes sp. 3, Amerodectes sp., and three helminths: Anonchotaenia sp., Capillaria sp. and M. papillosus. The flea Dasypsyllus (Neornipsyllus) cteniopus was found only on the Austral Blackbird. The only parasite species shared by both icterids was the acanthocephalan M. papillosus, possibly due to their feeding on the same intermediate insect hosts. With the exception of B. bonariensis and Philopterus sp. 1 found on the Shiny Cowbird, all species reported in this study represent new parasite-host associations and new records of parasite diversity in Chile.

We monitored reptile and bird roadkills in Cerrado–Pantanal landscapes along the Campo Grande to Corumbá highway BR-262. We describe species distribution in different landscape zones, including the first geographic record for Hydrodynastes bicinctus Herrmann, 1804 in the Pantanal basin. The roadkill occurrence of Spizaetus melanoleucus (Vieillot, 1816) is an outstanding record. We recorded 930 individuals belonging to 29 reptile and 47 bird species; 20 of these species are new roadkill records in Brazil. The 8 new records of reptile species include Eunectes notaeus Cope, 1862, Bothrops mattogrossensis Amaral,1925, Dracaena paraguayensis Amaral,1950 and H. bicinctus; and 12 new records of bird species include S. melanoleucus, Heterospizias meridionalis Latham, 1790, Urubitinga urubitinga (Gmelin, 1788), Pulsatrix perspicillata (Latham, 1790), Aramus guarauna (Linnaeus, 1766), and Jabiru mycteria (Lichtenstein, 1819). Richness of road-killed species on the BR-262 highway seemed to be high, reinforcing concerns about wildlife-vehicle collisions where these accidents occur, as they lead to long term and chronic impacts on wildlife and road safety in the Pantanal region.

Abstract The hippoboscids are cosmopolitan permanent obligate hematophagous ectoparasites of birds, domestic and wild mammals and, occasionally, humans. Some species may act as vectors or hosts of etiological pathogenic agents. The aims of this study were to report on the first cases of Hippoboscidae in Crax blumenbachii and Parabuteo unicinctus; to provide new reports from Brazil on Tyto furcata and Asio stygius parasitized by Icosta americana; to report on individuals of Bubo virginianus, Falco sparverius and Accipiter striatus parasitized by genera Ornithoctona; and to provide new reports on parasitism of O. erythrocephala in the state of Rio Grande do Sul. The birds of prey and C. blumenbachii were attended at a rehabilitation center in Porto Alegre and at a veterinary hospital in Cruz Alta. These new records demonstrate the huge gap that exists regarding studies on avian ectoparasites and highlight potential vectors of hemoparasites for the bird species studied.

Beak Deformity

AbstractBeak deformities in wild birds are rarely reported. Here, I described a case of beak deformity in Shiny Cowbird, Molothrus bonariensis, and also provide a review on beak deformities recorded in wild birds in Brazil. In October 2016, I observed a M. bonariensis with a grossly elongated maxilla in the east region of the Mato Grosso state, Brazil. The literature review revealed 60 records of beak deformities in the Brazilian avifauna. The most common types of deformity were crossed maxillae or mandibles (38%), probable accidental injuries (27%), and elongations (15%). Deformities were reported in 35 bird species of 22 families. The most affected species was Ramphastos toco with 21 records. The number of published reports from Brazil was low overall, and are not related as an epizootic episode recorded in some bird communities.

New records and possible range extensions are reported on 45 bird species (ca 25% of the 167 species recorded during surveys) in the Bophirima district of the North-West Province, South Africa. The findings were compared with data in The Atlas of Southern African Birds. The main reasons for these new records may be ascribed to the low number of visits during the atlas project, higher precipitation during the time of our observations versus that of the atlas project, and possibly an increased suitability of the area for some bird species due to human habitation. These new records also provide additional information that may be useful in conservation planning, especially in arid areas. Heuningvlei Pan in particular, should be considered for additional conservation measures.

AbstractThe Diptera occurring in various kinds of bird nests were investigated in the Japanese island of Hokkaido from 1985 to 1989. A total of 4623 Diptera, consisting of 23 species of eight families (Anthomyiidae, Fannidae, Muscidae, Calliphoridae, Heleomyzidae, Sphaeroceridae, Sepsidae, and Stratiomyiidae), was reared from 69 natural nests of 13 bird species of eight families (Strigidae, Picidae, Paridae, Sittidae, Sturnidae, Ploceidae, Laniidae, and Columbidae). Of 23 species of flies reared, 12 were new records from bird nests. An ectoparasite of birds, Protocalliphora maruyamensis Shinonaga and Kano, frequently emerged from the nests of hole-nesting birds of Paridae, Sturnidae, and Ploceidae, but it did not emerge from the nests of the hole-nesting birds Picoides major and P. minor of Picidae. The nests of Streptopelia orientalis yielded the most species of flies (12). Myospila meditabunda (Fabricius) and Mydaea urbana (Meigen), whose larvae are predacious, proved able to live in the bird nests. Among the scavengers, Potamia littoralis (R.-D.) was the most dominant and occurred in the nests of nine of 10 hole-nesting bird species. Sphaerocerid, sepsid, and stratiomid flies occurred in the nests of S. orientalis in which large quantities of bird feces had accumulated. The factors concerning the occurrence of flies in the nests are discussed.

Feeding associations between capybaras Hydrochoerus hydrochaeris (Linnaeus, 1766) and some bird species were registered in the Lami Biological Reserve, southern Brazil, through observations in a set of transects established in the five major vegetation types of the study area: shrubby and herbaceous swamps, wet grasslands, sandy grasslands and forests. Data included: date and time, vegetation type, bird species, number of individuals (birds and capybaras), type of prey consumed, foraging strategy of the birds and the behavior of the capybaras in relation to the presence of birds. Five species of birds were registered: Caracara plancus (Miller, 1777), Furnarius rufus (Gmelin, 1788), Machetornis rixosus (Vieillot, 1819), Milvago chimachima (Vieillot, 1816) and Molothrus bonariensis (Gmelin, 1789). The interactions were observed in the shrubby swamp (M. bonariensis), forest (C. plancus) and wet grassland (F. rufus, M. rixosus, M. chimachima). The foraging strategies were: (1) use of the capybara as a perch, hunting from its back (M. rixosus, M. bonariensis); (2) use of the capybara as a beater, hunting in the ground (F. rufus, M. rixosus, M. bonariensis); (3) foraging in the skin of the capybara, by picking the ectoparasites (C. plancus, F. rufus, M. chimachima). Strategies (1) and (2) were employed to catch arthropods flushed from the vegetation. Sometimes, capybaras lay down and exposed the abdomen and lateral areas of their bodies to facilitate cleaning by M. chimachima, but the presence of other bird species seemed to be neutral to capybaras.

Bird Assemblage

Suburban areas in the Pampas region of Argentina are inhabited by several bird species that sharply differ in their ability to exploit human-modified, urban areas. This bird assemblage includes species restricted to natural grasslands (e.g., Great Pampa Finch, Embernagra platensis (J.F. Gmelin, 1789)) as well as generalist, highly cosmopolitan species such as House Sparrow, Passer domesticus (L., 1758). We explored the role of certain aversive responses to novelty in shaping the marked differences in ecological plasticity among species in the assemblage. In field experiments, we tested for differences in feeding in the presence of artificial objects near feeders regularly replenished with seeds. In spite of their granivorous diet, some non-urbanized species did not use the feeders, possibly because of an extreme degree of aversion to novel situations. The group of birds that visited the feeders included both urbanized (N = 8) and non-urbanized (N = 2) species. We found that the presence of novel objects discouraged visitation to an otherwise attractive food source, although neophobia was weak for most species. However, we found unexpectedly high levels of neophobia in highly generalist, urbanized species such as House Sparrow and Shiny Cowbird, Molothrus bonariensis (J.F. Gmelin, 1789). This response is discussed in the context of the influence of post-fledging development in a relatively simple and predictable ecosystem versus that in urban areas.
