Extract Fifty-Nine
But it is ‘as the crow flies’ that is the most significant corvidian trait. It is commonly observed that ‘crows are afraid of water’ and that therefore when let loose from a ship will fly ‘straight to the nearest land’. This is an odd way of putting things. Crows do not have any strong feelings about water but since it is not their natural element, when released at sea, they naturally fly up to see where the nearest land is and fly directly towards it. Nothing very mysterious there.
But since being 'released at sea' is not something that will ever happen to a natural crow, we can perhaps put the whole thing into a more Megalithic context. Since crows (or a close relative) have been trained to fly in straight lines on land – to help out with surveying leylines and also demonstrating them to travellers – this learned behaviour has been applied to the sea. Or, one has to say, they were trained for maritime work and this skill was exploited on land or corvids fly straight naturally (for some unexplained reason) and this trait was exploited by humans when abducting and then training their nestlings.
But the point is crows, when released from a ship, will fly up to the necessary height and fly straight towards land. As we have seen, two thousand feet means England-to-the-Channel Islands so theoretically crows can handle most relevant sea-crossings. However, this is only moderately useful to sailors since knowing that the nearest land is ‘thataway’ does not solve many navigational problems. Sailors would much prefer to know ‘which land lies thataway’. Can crows distinguish between places? Can, for instance, crows tell tidal islands from the mainland? Or, since the various tidal islands have a differing number of Venus Pools, can they tell one tidal island from another? Can they land at a ‘monastery’, be given the name of the island and then fly back to the ship and repeat that word?
The answer to all these questions is, given the remarkable intelligence of the corvids in general and the peculiar aptitudes of the various corvidian species, is a resounding though entirely theoretical ‘yes’.
