Anthropogenic disturbances are a major concern for the welfare and conservation of wildlife. We recorded heart rate body temperature 20 free-living greylag geese in response to regularly re-occurring anthropogenic disturbance-New Year's Eve fireworks. Heart were significantly higher first second hour new year, compared with same on 31st December, average during December January. was not affected by sex or age. From 0200 0300 onwards, 1st January rates did differ from other periods; however, temperatures increased until 0300-0400. 0400 0500, any investigated factors, whereas but average. To conclude, our results show that New fireworks cause substantial physiological response, indicative stress geese, which is costly terms energy expenditure.

Anthropogenic noise and its effects on acoustic communication have received considerable attention in recent decades. Yet, the natural environment’s influence role shaping signals remains unclear. We used large-scale playbacks of ocean surf coastal areas whitewater river riparian to investigate how sounds influences song structure six songbird species. recorded individuals defending territories a variety conditions across 19 study sites California 18 Idaho. Acoustic characteristics included naturally quiet ‘control’ sites, ‘positive control’ that were adjacent or thus noisy, ‘phantom’ playback exposed continuous broadcast low-frequency noise, ‘shifted’ with shifted up frequency. predicted spectral temporal would generally correlate background sound amplitude signal features differ site types based profile environment. found ways which varied acoustics quite variable from species For instance, Idaho both frequency bandwidth duration lazuli bunting ( Passerina amoena ) sparrow Melospiza melodia songs decreased elevated but these unrelated warbling vireo Vireo gilvus ), tended increase minimum maximum amplitude. In California, trill white-crowned Zonotrichia leucophrys amplitude, matching results previous studies involving anthropogenic noise. contrast, wrentit Chamaea fasciata was positively related Although responses heterogeneous, all and/or Collectively, provide strong evidence soundscapes long influenced vocal behavior. More broadly, evolved behavioral long-standing challenges presented by sources likely explain many observed for communicating difficult human-made

Changes in bird migration phenology over six decades, a perspective from the Neotropical non-breeding grounds

Summary Changes in the migration phenology of birds linked to global change are extensively documented. Longitudinal studies from temperate breeding grounds have mostly shown earlier arrivals spring and a variety patterns during fall 1,2 , yet no addressed whether how has changed using data tropical non-breeding grounds. Understanding changes migratory also evident sites is essential determine underlying causes documented areas. Using historical scientific collections modern repositories community-science records, we assessed 12 Nearctic-Neotropical long-distance Colombia over six decades. We explored shared climatic niches explained variation phenological observed among species. All species showed shifts (range −37 – 9 days peak passage date) or −26 36 days) migration, but differed ways partly attributable wintering niches. Our results, although not broadly generalizable, suggest that use cues time their at which most likely different those they on To better understand effects biodiversity, exploring drivers with further research integrating more long-term datasets available through community science platforms should be priority.
