Ancient Egyptian art features many carefully observed depictions of wild animals and birds. A famous example is the late Eighteenth Dynasty (fourteenth-century BC) wall paintings of the Green Room in the North Palace at Amarna, where naturalistic depictions of birds feature prominently. Their taxonomic identity, however, is not resolved in all cases. Here, the authors revisit the facsimiles produced in the 1920s by Nina de Garis Davies. Mindful of previous works, taphonomy and the interplay between naturalistic observation and artistic licence, they employ ornithological resources to conduct a qualitative assessment and propose a parsimonious scheme of identifications, relating the results to long-standing questions concerning ecological and stylistic aspects in the artwork.

Avian influenza (AI) is an important disease that has significant implications for animal and human health. High pathogenicity AI (HPAI) has emerged in consecutive seasons within the UK to cause the largest outbreaks recorded. Statutory measures to control outbreaks of AI virus (AIV) at poultry farms involve disposal of all birds on infected premises. Understanding of the timing of incursions into the UK could facilitate decisions on improved responses. During the autumnal migration and wintering period (autumn 2019– spring 2020), three active sampling approaches were trialled for wild bird species considered likely to be involved in captive AI outbreaks with retrospective laboratory testing undertaken to define the presence of AIV.

Faecal sampling of birds (n = 594) caught during routine and responsive mist net sampling failed to detect AIV. Cloacal sampling of hunter-harvested waterfowl (n = 146) detected seven positive samples from three species with the earliest detection on the 17 October 2020. Statutory sampling first detected AIV in wild and captive birds on 3 November 2020. We conclude that hunter sourced sampling of waterfowl presents an opportunity to detect AI within the UK in advance of outbreaks on poultry farms and allow for early intervention measures to protect the national poultry flock.

Shade coffee is a well-studied cultivation strategy that creates habitat for tropical birds while also maintaining agricultural yield. Although there is a general consensus that shade coffee is more “bird-friendly” than a sun coffee monoculture, little work has investigated the effects of specific shade tree species on insectivorous bird diversity. This study involved avian foraging observations, mist-netting data, temperature loggers, and arthropod sampling to investigate bottom-up effects of two shade tree taxa - native Cordia sp. and introduced Grevillea robusta - on insectivorous bird communities in central Kenya. Results indicate that foliage-dwelling arthropod abundance, and the richness and overall abundance of foraging birds were all higher on Cordia than on Grevillea. Furthermore, multivariate analyses of the bird community indicate a significant difference in community composition between the canopies of the two tree species, though the communities of birds using the coffee understorey under these shade trees were similar. In addition, both shade trees buffered temperatures in coffee, and temperatures under Cordia were marginally cooler than under Grevillea. These results suggest that native Cordia trees on East African shade coffee farms may be better at mitigating habitat loss and attracting insectivorous birds that could promote ecosystem services. Identifying differences in prey abundance and preferences in bird foraging behaviour not only fills basic gaps in our understanding of the ecology of East African coffee farms, it also aids in developing region-specific information to optimize functional diversity, ecosystem services, and the conservation of birds in agricultural landscapes.

The identity of the passer in Catullus 2 and 3 has been a subject of controversy for hundreds of years.1 Sir D'Arcy Wentworth Thompson, the great authority on birds in the ancient world, sums it up best with his own musings: ‘Whatever Lesbia's “sparrow” may have been, I am pretty sure in my own mind […] that it was not Passer domesticus, the most intractable and least amiable of cage-birds.’2 Some scholars opt for an obscene interpretation of passer, while others argue that passer must refer to a bird like a bullfinch (Pyrrhula pyrrhula). To test the validity of these arguments, this paper examines four key components of the passer poems, and the passer debates. Firstly, it determines the Roman cultural view of sparrows and whether they regarded the birds as pets, pests, or something else entirely. Secondly, it analyses Roman trends in bird-keeping and looks for other examples of pet passeres in art and literature. Thirdly, it considers actual bird behaviour to reveal whether a sparrow could act the way Catullus describes. Finally, it analyses the different potential meanings of the word passer to determine which birds fell under its descriptive umbrella. In this way we can judge whether the passer was indeed a sparrow while also determining the place of sparrows in Roman thought and pet-keeping culture.

Farmland bird populations in Germany are declining at a higher speed than species inhabiting other habitats. We studied potential causes for bird population changes based on data from standardised German breeding bird monitoring schemes. We related population trends to covariates describing the changes in the agricultural landscape in Germany, weather conditions during the breeding season and for some migratory species, conditions at stopover and wintering sites. Linear mixed effect models were used to analyse effect strength at species level and conclusions are drawn for the overall group of farmland bird species. The area of grassland and fallow land was shown to have the strongest positive effects and the area of maize and rapeseed the strongest negative effects on farmland bird population trends. The results obtained also indicate that despite the consistent influence of weather conditions during the breeding season, land-use changes had a stronger impact on bird populations than weather. Conditions at Sahel wintering sites did not show a consistent effect on population trends. Based on these findings the study quantitatively underpins and ranks key factors shaping farmland bird populations in Germany.

Solidified stomach oil deposits in snow petrel colonies in the Antarctic proved to be suitable for 14C dating and provide important palaeobiogeographical and palaeoenvironmental information. Following earlier studies in the Untersee oasis (Central Dronning Maud Land) we present here 14C measurements on comparable deposits from the Bunger Hills (66°10′S, 101°E). The conventional 14C age of the basal layer reflects the occupation age of any particular nesting site and therefore a minimum age for the time when this area became ice-free. According to the 14C results the occupation of the southern part of the Bunger Hills by petrels started about 10000yr ago. The breeding colonies expanded continuously following local ice retreat. The most intensive phases of colonization seem to have been from 8–6 kyr BP and during the past 2 kyr.
