    “... In this first article, highlights include:
    • HRDEM & HRDEM Mosaic - over 709,000 km² of new LiDAR-derived elevation data added since May 2024, increasing coverage by 54%. This product now covers 244 of Canada’s 250 largest cities, and over 95% of the population.
    • Northern HRDEM data - fully updated using ArcticDEM v4.1, improving quality for the entire Canadian Arctic.
    • Automatically Extracted Buildings - Added 61 new projects and over 2.58 million building footprints, bringing the total to over 13.6 million.
    • LiDAR Point Clouds - Expanded by over 200,000 km2, now totalling close to 364,000 km²…”

  4. The growing body of research we have been conducting on #TheGrackleProject is showing that #behavioral #flexibility enables birds to #adapt to #human #modified #habitats 🌆 , but plays a smaller role in expanding into new #geographic areas 🗺️

    Moving to new towns likely involves more #persistence because we previously found that grackles on the edge of their range in northern California had similar levels of average flexibility (though higher variance), but were more persistent than grackles nearer the center of their range in Arizona peercommunityjournal.org/artic

    This is also supported by the fact that the preliminary data we were able to collect on persistence in boat-tailed grackles (who are not rapidly expanding their geographic range) showed that they are less persistent than great-tailed grackles, while having similar levels of flexibility
