Not all crickets are equal: selective shrike predation highlights the conservation value of diverse arthropod communities to grassland birds

open access: yesIbis, EarlyView.
Understanding dietary preferences and prey selection is pivotal for interpreting the ecology and conservation needs of threatened species. We investigated the diet composition and prey selection of the Red‐backed Shrike Lanius collurio in a montane grassland of the central Italian Apennines, with special regard to sex‐related differences and the ...

Population dynamics and reproductive success of Short‐eared Owls in relation to widely fluctuating food abundance and farmland habitat degradation

open access: yesIbis, EarlyView.
Populations of the Short‐eared Owl Asio flammeus have declined across Europe and North America, probably in response to habitat degradation driven by agricultural intensification. However, long‐term evidence linking farmland habitat change to variation in breeding density and reproductive success remains limited.

Arthropod Effect on Post-fledging Survival of the Dickcissel (Spiza americana)

open access: yes, 2016
The post-fledging period, the time period after leaving the nest to parental independence, is an important yet understudied portion of grassland bird lifecycles which may help determine how bird populations respond to habitat management.

A longitudinal study of avian pox in a small passerine, the Dunnock (Prunella modularis)

open access: yesIbis, EarlyView.
Long‐term, longitudinal studies of disease in wild bird populations are rare. Diseases are important determinants of bird survival and may spill‐over into other species including livestock and, in some cases, humans. Avian pox is a globally distributed disease, resulting from infection by viruses in the genus Avipoxvirus (APV).

Persecution by humans affects nest‐site selection of Hooded Crows: a comparison of an urban and two rural areas

open access: yesIbis, EarlyView.
The Hooded Crow, a bird species that once occurred only in agricultural areas, has colonized urban environments in the last 50–100 years in Europe. Apart from higher food availability, safer nesting sites, better thermoregulation and lower predation in cities, persecution through hunting, trapping or poisoning by humans in rural areas is an important ...

Timor-Leste's Foreign Policy: Securing State Identity in the Post-Independence Period

open access: yesJournal of Current Southeast Asian Affairs, 2014
This paper examines some of the major ideational aspects of Timor-Leste's foreign policy orientation in the post-independence period. Drawing upon the constructivist accounts of state behaviour, the paper situates Timorese leaders’ foreign policy ...

OBSERVATIONS ON THE POST-FLEDGING PERIOD OF THE COLLARED SPARROWHAWK (ACCIPITER CIRROCEPHALUS)

open access: yes, 2016
Observations on the post-fledging period of a brood of Collared Sparrowhawks (Accipiter cirrocephalus) were conducted for 64 hrs over 20 days in suburban Bunbaberg, coastal eastern Queensland, from the juveniles’ estimated third week post-fledging until ...

Predators control post-fledging mortality in tawny owls, Strix aluco

open access: yes, 2005
Despite its recognition as an important source of variation in recruitment probability, the ecological processes leading to mortality between fledging and independence are poorly studied.
