[obol] Brood Parasitism

[Larry McQueen]

Jack,

 

I think this is quite likely.  I once found a Snowy Egret egg in a clutch of
California Gull eggs in a gull colony along the Snake River in Idaho.  I
can't imagine the gull raising the egret, however!  Green Herons probably
use old crow nests as a starter kit, as they both nest in the canopy of
street trees.

 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?
