Don't forget to add observations to this project as you enjoy the Maple Highlands Trail this spring. Warbler migration is just around the corner, so late April and May will be good times to check out some of the wonderful habitat along the trail. Remember that iNaturalist also accepts sound clips as observations. The voice memo app on most mobile phones make decent recordings of birdsong. If you can't get a picture for documentation, try to get a recording instead. Happy spring!
