Haiku - Natural Alarms

NATURAL ALARMS ~~~~~~~~~~~~ spring procreation summer... autumn... helps for some winter works time tellers... birdsong dawn... the skylark up so high country life... birds thrill time tellers... birdsong nightingales... lullabies... sleep owls hoot till dawn rooks 15 minutes long the flock at dusk and dawn caw not no more... all gone* sparrows my alarm every morn they tweet me... call starlings amaze me** **they share the roost... two not many... clicks... long whistles churrings aplenty ~~~~~~~~~~~~~~ * For some twenty years I watch the flock grow. Followed it from roost to fields, then one day in 2014 it was gone. I checked the roost, it was for the most still there, but vacant. Asked around and no one had any answers, wouldn't even tell me who, or for what reason some trees were felled. The good news is a small flock 50+ are flying the same route whether they're using the same roost I cannot say?
