Comparing the power of phylogenetic, trait and network structure information to predict plant–frugivore interactions

open access: yesOikos, EarlyView.
Due to the constraints of limited effort and sampling error, observed species interaction networks are an imperfect representation of the ‘true' underlying community. Link prediction methods allow us to construct a potentially more complete representation of a given empirical network by guiding targeted sampling of predicted links, as well as offer ...

CRYPTOCOCCOSIS IN COLUMBIFORMES AT THE SAN DIEGO ZOO [PDF]

open access: yesJournal of Wildlife Diseases, 1978
Two cases of cryptococcosis in columbiformes exhibited at the San Diego Zoo are described. The organism isolated from the first case had morphological, chemical and temperature growth characteristics of C. neoformans. The culture from case 2 died before it could be examined biochemically or by mouse inoculation.

Holding a wing horizontal: Roles for muscles of the pectoral girdle other than the main two flight muscles

open access: yesJournal of Anatomy, EarlyView.
This report explores which muscles of the pectoral girdle are employed to allow birds to hold their wings horizontally with a level aerofoil surface during a glide. Abstract Whilst many birds glide briefly with wings held horizontally, some species maintain this posture for extended periods during soaring.

Investigation of Lethal Concurrent Outbreak of Chlamydiosis and Pigeon Circovirus in a Zoo

open access: yesAnimals, 2021
During the spring, an outbreak of sudden death involving 58 birds occurred in a zoo. Histopathological examinations revealed variable numbers of intracytoplasmic basophilic microorganisms in the macrophages, hepatocytes, and renal epithelium of most ...

Discriminating between nesting and non-nesting habitat in a vulnerable bird species: Implications for behavioural ecology [PDF]

open access: yes, 2019
Nowadays, partitioning amongst nesting and non-nesting habitats is not much studied. Here, I investigate whether or not the turtle dove (Streptopelia turtur) nesting habitats overlap with those used for other purposes in a North African agroforestry ...

Bacterial and Parasitic Diseases of Columbiformes

open access: yesVeterinary Clinics of North America: Exotic Animal Practice, 2009
Bacterial and parasitic diseases are not uncommon in domestic doves and pigeons. Many of the bacteria and parasites found in columbids do not cause disease unless the birds are immunocompromised. Often there are underlying viral infections that contribute to illness.

Courtship display behavior influences tail myology in Centrocercus minimus (Gunnison sage‐grouse)

open access: yesJournal of Anatomy, EarlyView.
Courtship displays among birds are widespread, particularly those which incorporate raised tail feathers for extended periods of time. The Gunnison sage‐grouse (Centrocercus minimus) is such a species. When we compared the tail muscles of the sage‐grouse to birds which do not engage in erected tail fan postures, both morphology proportional mass ...

Molecular epidemiological study of Trichomonas gallinae focusing on central and southeastern Europe

open access: yesFrontiers in Veterinary Science, 2022
Trichomonas gallinae is a geographically widespread protozoan parasite of birds. In this study, oropharyngeal swab samples were collected in Hungary and Romania from 99 columbiform birds, including 76 feral pigeons (Columba livia domestica: 42 kept for ...

Risks to Birds Traded for African Traditional Medicine: A Quantitative Assessment [PDF]

open access: yes, 2014
Few regional or continent-wide assessments of bird use for traditional medicine have been attempted anywhere in the world. Africa has the highest known diversity of bird species used for this purpose.

Citizen science reveals host‐switching in louse flies and keds (Diptera: Hippoboscidae) during a period of anthropogenic change

open access: yesMedical and Veterinary Entomology, EarlyView.
A study of louse flies in the United Kingdom, Isle of Man, and Ireland found 212 different interactions between Hippoboscidae and their hosts, of which 70 were previously unrecorded. No louse flies were found on aquatic species of birds. Host‐switching to gulls (Laridae) has occurred during a period in which these species have started relying on ...
