Disease outbreaks can drastically disturb the environment of surviving animals, but the behavioural, ecological, and epidemiological consequences of disease-driven disturbance are poorly understood. Here, we show that an outbreak of high pathogenicity avian influenza (HPAI) coincided with unprecedented short-term behavioural changes in Northern gannets (Morus bassanus). Breeding gannets have been characterised by strong fidelity to their nest sites and foraging areas (2015 – 2019; n = 120), but during the 2022 HPAI outbreak, GPS-tagged gannets instigated long-distance movements and the first ever recorded visits of adults to other gannet breeding colonies. Our findings suggest that the HPAIV outbreak triggered changes in space use patterns of exposed individuals that amplified the epidemiological connectivity among colonies and may generate super-spreader events that accelerate disease transmission across the metapopulation. Such self-propagating transmission from and towards high density animal aggregations may explain the unexpectedly rapid pan-European spread of HPAIV in the gannet.

“…The breakdown of that site delity shown here highlights the severity of the disturbance generated by the HPAI outbreak. It appears to be a short-term response, albeit at the peak infectious period, since gannets with surviving chicks GPStracked several months after the disease outbreak maintained their well-established routines 31 .…”

Based on the results of long-term observations, the colonization of the islands of the Murmansk coast, Barents Sea by northern gannets (Morus bassanus (L. 1758)) is described. The formation of colonies on the Murman Islands is shown to be associated with the restoration of the stocks of juvenile Atlantic herring in the Barents Sea in the 1990’s to the 2000’s along with an intense influx of birds from the Norwegian part of the species’ range. The population dynamics of the species in two Russian colonies are also analyzed. The end of the previous and the beginning of this decade were marked by an abrupt increase in population numbers in both Russian colonies. To date, the general distribution area of this species includes the southern part of the Barents Sea and the entire water area of the White Sea; the eastern border of its nesting distribution area being restricted to Kharlov Island, eastern Murman in the Barents Sea. Starting with 2022, the population dynamics in the westernmost Russian colony have been determined by mortality caused by the HPAIV avian influenza epidemic, this threatening further development of both Russian colonies. In the summer of 2023, using the phenotypic indicator of the previous infection, the number of sick birds in the colony was determined as amounting to 13–15% of the total number of individuals nesting there.

From 2020 up to summer 2023, there was a substantial change in the situation concerning the high pathogenic avian influenza (HPAI) virus in Europe. This change concerned mainly virus circulation within wildlife, both in wild birds and wild mammals. It involved the seasonality of HPAI detections, the species affected, excess mortality events, and the apparent increased level of contamination in wild birds. The knock-on effect concerned new impacts and challenges for the poultry sector, which is affected by repeated annual waves of HPAI arriving with wild migratory birds and by risks due to viral circulation within resident wild birds across the year. Indeed, exceeding expectations, new poultry sectors and production areas have been affected during the recent HPAI seasons in France. The HPAI virus strains involved also generate considerable concern about human health because of enhanced risks of species barrier crossing. In this article, we present these changes in detail, along with the required adjustment of prevention, control, and surveillance strategies, focusing specifically on the situation in France.
