Comparative analysis of behavioural response of captive-reared and wild-trapped Northern Bobwhites to simulated predator attacks

Posted on 16. March, 2018.

Isolated populations of Northern Bobwhites (Colinus virginianus) have declined causing many landowners to attempt population restoration by releasing captive-reared birds. These attempts have resulted in high mortality rates, which we hypothesised are caused by captive-reared birds exhibiting more naive predator avoidance behaviour than wild birds.

Prevalence of Toxoplasma gondii infection in domestic and migrating birds from Mazandaran province, Northern Iran

Posted on 13. March, 2018.

The zoonotic parasite Toxoplasma gondii is widely prevalent in humans and most warm-blooded animals worldwide, and is found in almost one third of the human population. There are a variety of modes of transmission of the parasite to intermediate hosts.

Variation in seroprevalence of antibodies against Mycoplasma gallisepticum and Avipoxvirus in nine species of birds with differential access to feeders

Posted on 9. March, 2018.

Congregation of individuals at high densities is known to increase disease transmission and bird-feeding activities are specifically aimed at attracting many birds to a single location. Studies have shown that implementing bird feeders increases the likelihood of host infection to Mycoplasma gallisepticum, a causative agent of conjunctivitis in birds.

Weather-dependent variation in the winter diet of urban roosting Long-eared Owls (Asio otus) in Pécs (Hungary)

Posted on 5. March, 2018.

Long-eared Owls usually winter in groups, mainly on evergreen trees in settlements, They hunt at night and rest in trees during the day. The indigestible parts of the prey (e.g. bones, hair, feathers and chitin) are regurgitated in the form of pellets, from which one can conclude the composition of their diet.

Weather-dependent variation in the winter diet of urban roosting Long-eared Owls (Asio otus) in Pécs (Hungary)

Posted on 7. February, 2018.

Long-eared Owls (Asio otus)  usually winter in groups in settlements, hunt at night and rest in evergreen trees during the day. From prey remnants regurgitated as pellets, one can detect species present in their hunting areas and changes in their abundance. Our aim was to reveal how the ratio of small mammal species in Long-eared Owl prey changes during the winter, since weather can influence hunting success and the availability of prey.

The dispersal of rodent-borne strains of Aphanoascus keratinophilus and Chrysosporium tropicum by pellets of predatory birds

Posted on 18. December, 2017.

Pathogenic species of yeast, yeast-like fungi and moulds have been recovered from faeces, feathers, beaks and cloacae as well as pellets of species of migratory and sedentary birds. Bird pellets, in particular pellets of predatory birds, are an especially suitable model for studies of circulation routes of dermatophytes and other keratinophilic fungi as they contain undigested food remains, which are rich in keratin (e.g. feathers, fur).

Development of novel microsatellite markers for the Northern Goshawk (Accipiter gentilis) and their utility in cross-species amplification

Posted on 12. September, 2016.

The Northern Goshawk (Accipiter gentilis) is a large forest raptor with a Holarctic distribution and, in some portions of its range, a species of conservation concern.

Plasticity in nest composition in relation to nest-site characteristics in the Red-breasted Flycatcher (Ficedula parva)

Posted on 24. June, 2016.

The nest is an important part of reproduction of many altricial bird species and nest construction is varied, for example in site selection, shape and construction material. In this paper, the authors studied nest composition in the Red-breasted Flycatcher (Ficedula parva), breeding in natural holes in primeval stands of the Białowieża Forest.

Perspectives on “Nest Construction and Function 2015”

Posted on 18. April, 2016.

Back in September 2012 Charles Deeming organised the first conference on nest construction and function, which was held at the University of Lincoln (Deeming, 2012). Even before the meeting was over he was being asked when the next meeting would be held.
