Tree swallows in protected Ontario reserve show declining reproduction and body size due to climate-driven insect loss, study finds
By
Bridget Stringer-Holden
Summary
New research published in a U.S. science journal reveals that tree swallows at Long Point Bird Observatory in Ontario have been producing fewer eggs and shrinking in body size since the 1970s, driven by declining insect populations linked to climate change. The study highlights how even protected areas cannot shield wildlife from the ecological impacts of a warming climate, as reduced insect availability affects bird reproduction and morphology.
