Cape Cod National Seashore plans a pilot program (at Duck Harbor
and Bound Brook in Wellfleet) to insert poisoned chicken eggs into fake piping
plover nests in a targeted effort to control certain crows that are eating
plover eggs. Crows have learned the exclosures (3-foot-high fences with netting
on top) protect defenseless piping plover chicks that can be eaten once they
emerge.

Hang gliding and Paragliding pilots are not the only ones who
can't fly the national seashore during the nesting season for Piping Plovers
(April thru October!). This just ain't right.
