The Purple Martin Conservation Association invited the public to join them Wednesday night on Erie's South Pier, to enjoy the sunset....followed by the arrival of tens of thousands of purple martins.

They have arrived to rest up in Erie, before their migration to the Amazon Rainforest.

The Purple Martin Conservation Association staff gathered on the pier, and shared their knowledge of these amazing birds with those who came out to witness the incredible sight.
