Obviously, crows have at least the same level of intelligence as a moderately successful politician. (Anyone who's watched crows in the wild much will not be too surprised at this, although it's at the "top end" of what I've seen them do.) John |

The one where the crow modifies the straight piece of whatever it is to make a hook to retrieve a treat is quite sommat. Of course, many animals are intelligent to a ceratin degree, including humans... at times. |

Crows mimic the seagulls, but aren't always so accurate. It's funny, at the beach on foggy days (I heard it a lot on San Juan Island at the National Historic Park on the north end, English Camp). At low tide, the birds still feed, but more often when you hear a soggy "splat!" it is a crow that missed the rocks and hit wet sand when it dropped a clam. It's an eerie sound in the fog. :) SRS |

Been a fair few tires flattened by clam shell shards. So, they painted seagull outlines on the pave to trick gulls in the air. Dunno if it works. |

They are high enough to clear small vehicles but suffer a high mortality to the trucks. However they multiply faster than rabbits so are in no danger of extinction. A crow is always aware of dangerous surroundings but the greedy gulls often forget to look both ways. |
