eBird servers will be unavailable on 23 June between 03:30-08:00 ET (07:30-12:00 GMT), due to regularly scheduled maintenance. We have to do this periodically to keep everything up to date and offer the best user experience possible. Please log your sightings in a notebook or in the eBird Mobile app for later entry, since you will be unable to submit checklists during that time. Thank you for your understanding!
