Dear Barbara and Lincoln neighbors, Barbara,
Thank you for your patience in taking & then sharing the remarkable photo. I appreciate the added information about the impact of light at night on the ruby-throated hummingbird. Lincoln neighbors, If any residents have interest and capacity to join the Dark Skies subcommittee, we anticipate an opening soon. Please reach out to me privately for more information. The Dark Skies Subcommittee is active, meeting 2x/month in the evening (usually on Wednesday) with “action items” and/or committee work to complete between meetings, along with opportunities to engage in additional meetings and educational tasks to achieve and uphold Dark Skies in our community.
