To a boat owner, this is not a welcome sound. When you are just waking up, these are the kinds of thoughts that run thru your head:
- Someone has drifted into us (drug their anchor, miss-judged their scope, etc); damage has ensued
- A log is drifting past the hull (does it have rusty spikes in it?); damage has ensued
- We've hit bottom on an outgoing tide; damage has ensued
- ...; damage has ensued
Then I noticed, on the aft deck, a clam, freshly broken.
Gulls and crows have learned this trick: at low tide, find a clam that you can lift and fly with. Take it high enough, and drop it onto something hard - it breaks open and you can feast. In this case it was a crow, who was very displeased with me for throwing away his breakfast, and he told me so.
I ignored him, and went back to bed, thinking that birds deserve way more credit for intelligence than we give them.
