The effects of human visitation, pets, livestock grazing, buildings, and other 

 human activities on breeding seabirds need to be determined, and the extent to 

 which these activities affect current colonies needs to be assessed. 



The influence of human disturbance (dogs, bird watchers, boats, and clam- 

 diggers) on concentrations of feeding and roosting shorebirds, and the degree 

 of the problem along the coast of Maine needs to be determined. If human 

 disturbance is found to be adversely affecting waterbirds, methods need to be 

 devised to mitigate or eliminate these disturbances.
