Abstract In human-dominated landscapes, human disturbances may contrast (spatially and/or temporally) with risk imposed by non-human predators. However, how prey adjust behaviour to minimize from multiple threats remains unclear. Central-Western France, we investigated patterns of activity, space and habitat use, causes variations during the diel cycle grey partridge (captive-reared, released),...

One-hundred twenty-three gizzards from upland game birds (chukar, Alectoris chukar; and common pheasant, Phasianus colchicus) harvested by hunters in southern Ontario, Canada, were examined for lead pellet ingestion by manual examination of gizzard contents and by radiography. Lead pellets were found to be ingested by chukars (6/76; 8%) and the common pheasant (16/47; 34%). Further, 13% (17/129...

This paper describes how different animals cope with the challenges of orienting in very diverse environments. First, a broad general overview is given. Then, as a case story, bird migration is treated in more detail. The aim of the paper is to encourage designers of mobile robots to consider the natural solutions already used by animals when developing navigation systems for their robots. q 20...

Chlamydiae are important pathogens of a range of birds and animals including sheep, cattle, pigs, cats, goats, koalas, other Australian marsupials, amphibians and reptiles. Recent changes to chlamydial taxonomy has seen the proposal of two genera, Chlamydia/Chlamydophila with nine species – C trachomatis, C muridarum, C suis, C psittaci, C pecorum, C abortus, C caveae, C felis and C pneumoniae ...

Cestodes or tapeworms (Class Cestoda, phylum Platyhelminthes) are widespread parasites of birds, as they cause various damages, which may lead to the death their hosts, especially when infection is severe. The Black Francolin belongs Phasianidae family pheasants and, in order Galliformes, gallinaceous and it called Francolinus francolinus. Considering a local bird Asia, was referred black partr...
