BirdCast Forecasts and Alerts are back online

BirdCast team The Cornell Lab May 28, 2025

Update: 28 May, 10am ET. The technical issues with the migration forecasts and alerts have now been resolved. Thank you for your patience as we worked through various fixes.

Additionally, we would like to highlight, since some have noticed, that Canada is still not included in our BirdCast coverage despite the appearance of recent graphics. Though we have been exploring partnerships for several years to collaborate with our Canadian colleagues, any current graphics showing coverage in Canada are related only to the technical issues rather than to new data or a new product.

Please note, when viewing migration forecasts, you may need to force a refresh of your browser to see graphics appear in their most up to date form.
