Virome in the cloaca of wild and breeding birds revealed a diversity of significant viruses. [PDF]

Microbiome, 2022
Wild birds may harbor and transmit viruses that are potentially pathogenic to humans, domestic animals, and other wildlife. Using the viral metagenomic approach, we investigated the virome of cloacal swab specimens collected from 3182 birds (the majority

Long-term and large-scale multispecies dataset tracking population changes of common European breeding birds. [PDF]

Sci Data, 2021
Around fifteen thousand fieldworkers annually count breeding birds using standardized protocols in 28 European countries. The observations are collected by using country-specific and standardized protocols, validated, summarized and finally used for the ...

Cooperative breeding and the emergence of multilevel societies in birds

bioRxiv, 2021
Multilevel societies (MLSs), where social levels are hierarchically nested within each other, are considered one of the most complex forms of animal societies. Although thought to mainly occur in mammals, it is suggested that MLSs could be under-detected

Detecting the non-breeding region and migration route of Whimbrels (Numenius phaeopus rogachevae) in the East Asian–Australasian Flyway

Avian Research, 2022
Determining the migration routes and connections of migratory birds at the population level helps clarify intraspecific differences in migration. Five subspecies have been recognized in the Whimbrel (Numenius phaeopus) in Eurasia. Ssp.

Drones, automatic counting tools, and artificial neural networks in wildlife population censusing

Ecology and Evolution, 2021
The use of a drone to count the flock sizes of 33 species of waterbirds during the breeding and non‐breeding periods was investigated. In 96% of 343 cases, drone counting was successful.

Intra-tropical movements as a beneficial strategy for Palearctic migratory birds [PDF]

Royal Society Open Science, 2018
Migratory birds often move significantly within their non-breeding range before returning to breed. It remains unresolved under which circumstances individuals relocate, whether movement patterns are consistent between populations and to what degree the ...

Nutritional quality assessment of different muscles derived from 15-year-old female emus (Dromaius novaehollandiae): Meat physicochemical traits and sensory scores

Czech Journal of Animal Science, 2019
The emu (Dromaius novaehollandiae) is considered a versatile farm species whose main by-products are meat and oil. At present, there is lack of information on the value of the meat of laying females at the end of their reproductive cycle which hampers ...

Variation in female reproductive tract morphology across the reproductive cycle in the zebra finch [PDF]

PeerJ, 2020
Background In seasonally breeding birds, the reproductive tract undergoes a dramatic circannual cycle of recrudescence and regression, with oviduct size increasing 5–220 fold from the non-breeding to the breeding state.
