Several days ago at dusk, I was driving through Johnson Park past the large pond across from the old zoo. Multiple Cormorants were flying in and perching on the one of the higher branches of the largest tree between the pond and the Raritan River (where frequently an Eagle is perched). One Cormorant was flying in and suddenly was jerked upwards. It seems that one of his feet was entangle in a fisherman’s monofilament line and the other end of the line in a tree branch. As hard it tried flapping it wings to get untangled, it did not happen. For the next few days its body upside down swung back and forth in the breeze. On the fourth day, the body was gone. Fell to earth, removed by a predator?
The important point is that monofilament fishing line should be discarded properly. There are containers for the filament by both of the major ponds in Johnson Park (see figures below).
