Functional traits and foraging behaviour: Avian vampire fly larvae change the beak and fitness of their Darwin's finch hosts

Functional Ecology, Volume 36, Issue 7, Page 1806-1817, July 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract The avian beak is a key morphological trait used for foraging. If parasites alter beak shape, we may expect changes in host foraging behaviour. Larvae of the avian vampire fly Philornis downsi cause naris enlargement in Darwin's finch nestlings when first and second ...

Ability to detect antibodies to beak and feather disease virus in blood on filter paper decreases with duration of storage [PDF]

PeerJ, 2021
Background Beak and feather disease virus (BFDV) is a circovirus that infects captive and wild psittacine birds, and is of conservation concern. The haemagglutination inhibition (HI) assay is used to determine antibody titres against BFDV, and the use of

Identifying cost‐effective recovery actions for a critically endangered species

Conservation Science and Practice, Volume 4, Issue 1, January 2022., 2022
A structured approach for evaluating conservation options for the critically endangered orange‐bellied parrot. Management scenarios where more fledglings were released were more cost‐effective compared to other options, which once implimented contributed to an increase in wild birds migrating in 2020.

A blocking ELISA for the detection of antibodies to psittacine beak and feather disease virus (BFDV) [PDF]

Journal of Virological Methods, 2009
Currently, the only diagnostic test available routinely for the sero-diagnosis of BFDV is the haemagglutination-inhibition (HI) assay. This test, whilst useful and applicable to samples from a wide range of psittacine birds, is not an ideal assay; it requires erythrocytes from live animals, virus purified from the feathers of infected birds and ...

Molecular detection and analysis of beak and feather disease viruses in Iran

Frontiers in Veterinary Science, 2022
The beak and feather disease virus (BFDV) is one of the few pathogens capable of causing extinction of psittacines. To determine the prevalence and the nature of BFDV mutation, this study investigated the presence of the BFDV among 1,095 individual birds

Detailed monitoring of a small but recovering population reveals sublethal effects of disease and unexpected interactions with supplemental feeding [PDF]

, 2015
Infectious diseases are widely recognized to have substantial impact on wildlife populations. These impacts are sometimes exacerbated in small endangered populations, and therefore, the success of conservation reintroductions to aid the recovery of such ...

Molecular Survey of Pathogens in Wild Amazon Parrot Nestlings: Implications for Conservation

Diversity, 2021
South America presents the greatest Psittacidae diversity in the world, but also has the highest numbers of threatened parrot species. Recently, exotic viruses have been detected in captive native psittacine birds in Brazil, however, their impacts on the

Psittacine beak and feather disease outbreak in captive rose-ringed parakeets (Psittacula krameri) in the State of Ceará, northeastern Brazil [PDF]

Pesquisa Veterinária Brasileira
: Psittacine beak and feather disease (PBFD) affects Psittaciformes worldwide. In Brazil, PBFD is an emerging disease that has threatened exotic and native Psittaciformes in captivity; however, reports in the country are still scarce.

Dual ATPase and GTPase activity of the replication-associated protein (Rep) of beak and feather disease virus

, 2018
Psittacine beak and feather disease affects parrots resulting in an immunosuppressive disease that is often characterized by an abnormal shape and growth of the animal's beak, feathers, and claws.
