This may be a stupid question. But how do you go about assessing that around the shore? If say I had a net and caught them would they go back to the bed when released?? I know birds are funny about a disturbed nest. Are fish? I know if my daughters see them they'll toss a hook over there. I never thought about if they would return to the nest until this discussion. If caught will they go back and finish their job? I have used binoculars from about 10 to 15ft away and you can make them out really well. I may need to try that again. That was the only way I could see them last year without them darting away.
