Abstract

Global changes are leading to widespread species redistribution. Comprehensive assessments of range shift dynamics and their drivers are difficult, partly due to the variation in range shift detection over space and taxa. Here we compile documented range shift records for 1,758 butterfly species from 105 countries and territories, representing ~10% of the known diversity of these insects. Most species (80%) experienced range expansions, and most range shifts (79%) were associated with climate change and extreme weather events. A substantial proportion of species in our dataset contracted their ranges (27%) or shifted along elevational gradients (22%). We report widespread horizontal range expansions and contractions across tropical countries, with less evidence for elevational range shifts. We show that a clearer picture of range shift dynamics emerged only through the combination of different types of data, with expert assessments and non-English studies alleviating potential biases. Our findings of climate-driven range shifts call for concerted efforts to improve inclusive data monitoring and conservation efforts, especially for tropical countries, where human-induced land-use changes exert additional critical pressure.

*NOTE: In January 2020, the name of our partnership was changed from the Wisconsin Bird Conservation Initiative (WBCI) to the Wisconsin Bird Conservation Partnership (WBCP).

Members of the Issues Committee of the Wisconsin Bird Conservation Partnership have prepared a series of “Issues Papers” to provide information for WBCP partners and the public. These documents contain an overview of of the topics and sections covering WBCP Goals, Research Findings in Wisconsin and Elsewhere, Recommended Actions, Additional Research Needs, Links, and Additional Literature.

All of the following are printable PDF files:

• The Status of Midwest Aerial Insectivores

• Effects of Pesticides on Birds

• Climate Change and Birds

• Effects of Deer Herbivory on Birds

• Wind Power and Birds: WBCI Policy and Guidelines

• Window Collisions and Birds

• Ethical Standards in Birding: Protecting Endangered, Threatened, and Rare Species

• Effects of Free-ranging Cats on Birds in Wisconsin

• Lead Poisoning of Wisconsin’s Birds

 This is another one of the "scientists' warnings" papers (The 2025 state of the climate report: a planet on the brink ).

From the abstract:

" We are hurtling toward climate chaos. The planet's vital signs are flashing red. The consequences of human-driven alterations of the climate are no longer future threats but are here now. This unfolding emergency stems from failed foresight, political inaction, unsustainable economic systems, and misinformation. Almost every corner of the biosphere is reeling from intensifying heat, storms, floods, droughts, or fires. The window to prevent the worst outcomes is rapidly closing. In early 2025, the World Meteorological Organization reported that 2024 was the hottest year on record (WMO 2025a). This was likely hotter than the peak of the last interglacial, roughly 125,000 years ago (Gulev et al. 2021, Kaufman and McKay 2022). Rising levels of greenhouse gases remain the driving force behind this escalation. These recent developments emphasize the extreme insufficiency of global efforts to reduce greenhouse gas emissions and mark the beginning of a grim new chapter for life on Earth."

 

a week in Gr Smoky Mts NP

 

My family spent a week hiking in Great Smoky Mountains National Park. 

 

 

Along with my search for birds, we all were in awe of many "old-growth" trees in the forests of the park. One particularly-noteworthy area was the Cosby Creek trail, with many small streams, and many large trees,

 At high elevations in the national park, Dark-eyed Juncos, Common Ravens, and Black-capped Chickadees are found (in the range where Carolina Chickadees are espected, but at lower elevations).

 

These Bluets were seen there: 

 

Here, along the Oconaluftee River, we saw 3 elk. 

 

 

Because I live in southeastern WI, many songbirds encountered in GSMNP are very uncommon to slightly "rare" where I live:

Blue Grosbeak

Summer Tanager

Worm-eating Warbler 

Black Vulture,

and most uncommon of all,

Swainson's Warbler.
