[obol] Brood Parasitism

[Jack Holley]

 Yesterday as My wife and I were walking our dog in a park in SE Portland, I spotted two young birds not able to fly jet hopping around on the ground. The first was a young crow, and the second was a young Green Heron. There were no marshy areas close to the park. Crows were  flying from one to the other birds. I was wondering if anyone has heard if Green Herons lay their eggs in other birds nest?
