Atlas notes: Peak bird breeding period in Southern Ontario begins on Saturday 24 May and continues through to 10 July. If you are out and about, remember that almost every bird you encounter can be added to the Third Ontario Breeding Bird Atlas: a once in a generation province-wide community-science effort to provide data that will help shape conservation efforts for years to come. Though 2025 is the final year of the Third Atlas, every observation is still welcome and very much valued: whether a bird seen or heard in appropriate habitat (possible breeding) through to a bird carrying nesting material or food (confirmed breeding). Many observers have now switched their bird reporting from the eBird app to the Nature Counts atlassing app. It is a simple and efficient way to add your sightings to the Atlas project and it can be configured to automatically and seamlessly share your Atlas observations with your eBird account. For more information on the Atlas, please visit www.birdsontario.org or contact the Ottawa Regional Coordinator at Ottawa@birdsontario.org
