Utility officials are on the lookout for returning ospreys that nest in the cross arms of utility poles on Cape Cod. Ospreys, also called sea hawks, return each spring from their southern winter homes. NStar says it's watching for potential problem.

Kevin McCune, NStar's supervisor for licensing and permitting, says birds can sometimes be killed by electricity or fire.

Possible solutions include removing a nest and hoping the birds choose a more natural roost and installing a device to prevent them from nesting.

Another solution is to put up a nearby platform to encourage the birds to move.
