“…When considering the impact of trophic ecology on the concentrations of trace elements in the feathers of Cape petrel and Wilson's storm petrel, we did not find any positive or negative associations between any given element and the three stable isotopes. This contrasts with the findings of Padilha et al (2023) who observed that foraging area and dietary sources impact Zn, Ba, Sn, and Cd concentrations in migratory seabirds in Antarctica. However, this was not found in the present study.…”

“…These values were an order of magnitude lower compared to the current study. Padilha et al (2023) observed concentrations of Ca, Cd, Mg, and Cr (Table 3) in breast feathers of Giant petrel (Macronectes giganteus), a seabird species with a similar migratory distribution to Cape petrel, at least were an order of magnitude lower than the present study (Patterson and Hunter, 2000). The variations in trace element concentrations highlight the possible impacts of differing environmental conditions, exposure rates, feather types, and time-sensitive factors on the biochemistry of these marine birds (Dauwe et al, 2003;Jerez et al, 2011).…”

“…Subsequently, the feathers were cut into small pieces using ceramic scissors. For stable isotope analysis, the samples were additionally washed with a chloroform/methanol (2:1, v: v, suprapur Merck, Germany) solution and dried at 50 • C for 48 h (Padilha et al, 2021(Padilha et al, , 2023.…”

“…Ultra-performance liquid chromatography-tandem ES (− ) mass spectrometry (UPLC-MS/MS, ACQUITY, TQD, Waters, Milford, MA, USA) was used to measure four perfluoroalkane sulfonic acids (PFBS, PFHxS, PFOS, and PFDS) and eleven perfluoroalkane carboxylic acids (PFBA, PFPeDA, PFHxA, PFHpA, PFOA, PFNA, PFDA, PFUnDA, PFDoDA, PFTrDA, and PFTeDA) were selected as target analytes. For quality control of the samples, the procedures are further explained in Padilha et al (2022Padilha et al ( , 2023 for trace elements and PFAS, respectively. The abbreviations utilized for the target PFAS are consistent with those proposed by Buck et al (2011; see Table S1 in the Supplementary Material).…”

“…Kelp gulls, Snowy sheathbills, and Brown skuas are often mentioned as main vectors of the disease due to their short-range migratory capabilities (i.e. (Krasnobaev et al, 2018; Padilha et al, 2023). This complexity presents challenges in elucidating their potential contributions to disease dissemination.…”

From December 2023 to March 2024, a surveillance program to detect HPAI H5N1 was performed on Antarctica Territory, at Fildes Peninsula (King George Island, Maritime Antarctic), and James Ross Island. At Fildes Peninsula, samples from marine birds and mammals from four sampling locations were collected, based on their accessibility and the presence of animal colonies: Ardley Island, which presents a high concentration of Gentoo penguins (Pygoscelis papua); Ardley Cove were small groups of likely non-reproductive Chinstrap penguins (Pygoscelis antarcticus); Southern elephant (Mirounga leonina) and Weddell (Leptonycotes wedellii) seals haul-out sites; and, a nesting site of Southern giant petrels (Macronectes giganteus). On February 28th the surveillance group received a request for sample collection, due to the observation of deceased seabirds at James Ross Island in the area neighboring the Lachman lakes (63.7989 S, 57.8105 W). Six samples from five dead South polar skuas (Stercorarius maccormicki) were collected on March 3rd, 2024. All samples were collected adhering to the Antarctic Treaty guidelines. After collecting a total of 943 samples from Fildes Peninsula all results tested negative, and no individuals had clinical signs or behaviors compatible with HPAI. However, all samples from South polar skuas from James Ross Island were confirmed positive for HPAI H5N1 clade 2.3.4.4 by specific real-time RT-PCR reactions. These results confirmed the first mortality event registered in Antarctica (south of 60 degrees south) caused by HPAI H5N1, in this case on South polar skuas. Further studies are needed to genetically characterize the virus and to better understand the role of skuas in the dynamics of viral dissemination in Antarctica.

This study investigated the feathers' composition of South polar skua (Stercorarius maccormicki) using WDXRF, evaluating the concentration of essential and non-essential elements in the feathers, and dividing it into rachis and barb parts. We collected South polar skuas feathers from Hennequin Point, King George Island, South Shetland, Antarctic Peninsula in January of 2013. Our results show that 18 elements were observed in the composition of the feathers, with a different concentration between the rachis and barbs, qualitatively and quantitatively. Only 3 elements observed were classi ed as non-essentials but still mostly elements do not have a function described in the literature to the feathers. According to our knowledge, this is the rst study that uses this technique to evaluate the concentration of different elements in the feathers. The ndings of this study highlight the use of alternative techniques to biomonitoring elements in the ecosystem and bring baseline information for future studies.
