I remember from growing up in Washington DC, the turkey vultures arrived in the autumn, and most left again in the spring. I figured they went north. Over the winter they hung out at the reservoir (yep, our drinking water), which was a holding impoundment between the Potomac river and the water treatment plant. There was a glut of eels that came up with the river water at the time. Seagulls would scoop them up, but dropped many on the grass, and the vultures scarfed them up. An early lesson in systems behavior for me. erik ..................................
