New Bird Population Trends report on Chicago Region from the Bird Conservation Network

The Bird Conservation Network (CAS is a member) has today released a comprehensive study of the population trends of the breeding birds of the Chicago Region. It contains some conclusions which may surprise you. Our region is very important for quite a few birds of conservation concern. Many are doing very well here (thanks in part to efforts of the regions public land managers), but others are declining. See all the trends and read the report at bcnbirds.org/trends21.

Urban Ornithology: New Study on Avian Nesting & Climate Change from Chicago Ornithologists

Urban Ornithology: New Study on Avian Nesting & Climate Change from Chicago Ornithologists

In Spring 2022, the Journal of Animal Ecology published an extensive study about avian nesting behavior and climate change conducted by a group of Chicago-based ornithologists. Researchers from University of Chicago, Lincoln Park Zoo, and the Field Museum utilized field observations and the museum’s historical records to track nesting dates for 72 species of birds spanning 143 years. This article not only serves as an interesting contribution to the scientific community, but also as a testament to the prominence of Chicago’s institutions and its urban ornithologists. In hopes of getting this information to as many birders as possible, past the inaccessibility of statistical jargon and academic pay-walls, we offer a short summary.

Camp Pine Woods Habitat Restoration: 2022 Wrap-up

The fall of 2020 saw the first prescribed burn of the prairie/shrubland in recent memory, knocking back some of the invasive buckthorn that had begun to creep back from previous removal efforts. Multiple acres of woodland were also cleared of buckthorn and other invasive species, some of which have now been re-seeded with native grasses, sedges, and flowers. Over 200 oak and hickory saplings were located and caged in these cleared areas, paving the way for the next generation of large trees.
