Join Genesee Valley Audubon Society Nov. 19, 2024 at 7:30 pm for Supplementary Bird Feeding as an Overlooked Contribution to Local Phosphorus Cycles by Zoom, Ethan S. Duvall, Researcher on this paper, PhD Candidate at Cornell University.
This paper caught the attention of this forum this summer. A number of you disagreed with the findings. This is a chance to learn more about the research and findings.
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 program; email June Summers at <summers...> by November 18.
