Author: Published: 2025 12.11.25 Papers View on journal website Temporal changes to migratory fuel load in migratory birds across Europe Author: Published: 2025 Data from bird ringing show changes in the timing of birds feeding up before their autumn migration across Europe over the past 40 years, and a decrease in the extent of fattening recorded. This decline was strongest in southern Europe and was linked to rising temperatures associated with climate change. 10.11.25 Papers View on journal website Solar radiation affects bird distributions but not elevational shifts in European mountains Author: Published: 2025 Research involving BTO shows bird species moving toward colder areas in the mountains of Europe as the climate has warmed over the past two decades. 03.11.25 Papers View on journal website Fast trills in songs of a small passerine are not reliable signals of individuals’ age or predictors of mating success Author: Published: 2025 Soft trills in Tree Pipit songs were suggested to indicate male quality to females. This study found soft trill rates and regularity, but not duration, improve with the age of males, but this improvement is too low to make soft trills a reliable age or quality signal. Correspondingly, paired and unpaired males did not differ in trill characteristics. 03.11.25 Papers View on journal website Genomic architecture of egg mimicry and its consequences for speciation in parasitic cuckoos Author: Published: 2025 Cuckoos are brood parasites, meaning they lay their eggs in other species' nests, and the resulting chicks are raised by the host species. Cuckoos therefore face strong evolutionary pressure for their eggs and offspring to match those of their hosts, yet each Cuckoo species parasitises multiple hosts. This study examines the genetic basis of egg coloration in the Common Cuckoo and the Oriental Cuckoo. 30.10.25 Papers View on journal website Combining temperature-depth recorder and GPS data improves identification of foraging habitat in diving seabirds Author: Published: 2025 14.10.25 Papers View on journal website Breeding and foraging habitat are important in determining foraging ranges of sympatric generalist species Author: Published: 2025 This study examines the foraging ranges of Herring Gulls and Lesser Black-backed Gulls during the breeding season to help identify and resolve potential human–wildlife conflicts. 07.10.25 Papers View on journal website Pagination First page First Previous page Previous Page 1 Page 2 Page 3 Page 4 Page 5 Page 6 Page 7 Page 8 Page 9 … Next page Next Last page Last
