Some of you remember this research paper from this summer. Genesee Valley Audubon has invited Ethan Duvall, one of the researchers and authors, to speak on his research. We hope you will join us to get the full picture of this research and results.
Nov. 19, 2024 Supplementary Bird Feeding as an Overlooked Contribution to Local Phosphorus Cycles, Ethan S. Duvall, Researcher on this paper, PhD Candidate at Cornell University
Supplementary feeding of garden birds and gamebirds is a common practice worldwide. Bird feed is rich in phosphorus (P), which plays a key role in animal health and ecosystem function. However, much of the P in bird feed originates from mined rock deposits, which is then transported thousands of kilometers to feeder stations, where it represents an external source of nutrients for recipient ecosystems. Phosphorus provided to garden birds alone is equal to that supplied through the application of garden fertilizers. How does this change the ecosystems around our yards?Please register for this Zoom program; email June Summers at <summers...> by November 17. You will receive link the day before the program.
