The blue-tipped puffer is a migratory bird that is found along the coast of this state in summer months  The puffers enjoy the seeds of Thomson' s Mulberry trees; because these trees are plentiful in the state' s Coastal Park, traditionally many blue-tipped puffers would be found in the park during summer months  Ten years ago, the grey fox, a primary predator of the puffer, was re-introduced into the park, and its numbers have been thriving  Over that time, we have seen many fewer puffers in the park during the summer months
Clearly, the puffers are choosing to spend their summers elsewhere
Whether the range of the grey fox within the park extends all the way to the coast.
