The Purple Martin pre-migratory roost at Presque Isle State Park in Erie, Pennsylvania is reaching its peak! If you're in the area, stop by! You don't want to miss this! 💜 The best place to view the roost is Vista 1 (the first parking lot on the right, on Presque Isle State Park) or from Sommerheim Water Treatment Plant (across the Bay). The best time to view the roost is around/after 8 PM. You can learn how to spot roosts on weather radar here: https://www.youtube.com/watch?v=5RwDe7qfwyU #Purp
