ah yes you need to shoot birds; the seagulls land at night near the seashore
and during storms day or night; you can use wood arrows
they won't move; trying to shoot them in sunshine is pointless: I swear they
teleport away as soon as you aim at them
it seems that you must aim above them no matter how close; watch the flight
of the arrow

supposedly you can hit them in the air; never managed that myself

shoot any bird you see; you will always need feathers
