Light as a Feather

This rook is pushing its luck, mucking about like that in a guitarra player's apartment in Lisbon.  There's going to be a very expensive accident, and rooks very rarely have insurance.  Neither do struggling musicians.  Although I see this one has been able to afford the insanely expensive guitarra azul.

Stringed instruments are often surprisingly light, when you pick them up.  A good violin can seem as weightless as a balsa-wood model aircraft.  Birds, on the other hand, generally seem heavier than they have any right to be.  Every Christmas I wonder at the weight of our goose when I collect it from the butcher.  It could have flown between continents, and yet stripped down and oven-ready it's still as heavy as a bag of tools.
