I work with Volunteers for Wildlife，a rescue and education organization at Bailey Arboretum in Locust Valley.Trying to help injured，displaced or sick creatures can be heartbreaking； survival is never certain.However，when it works，it is simply beautiful.
I got a rescue call from a woman in Muttontown.She had found a young owl (猫头鹰)on the ground.When I arrived，I saw a 2－to 3－week－old owl.It had already been placed in a carrier for safety.
I examined the chick(雏鸟)and it seemed fine.If I could locate the nest，I might have been able to put it back，but no luck.My next work was to construct a nest and anchor it in a tree.
The homeowner was very helpful.A wire basket was found.I put some pine branches into the basket to make this nest safe and comfortable.I placed the chick in the nest，and it quickly calmed down.
Now all that was needed were the parents，but they were absent.I gave the homeowner a recording of the hunger screams of owl chicks.These advertise the presence of chicks to adults；they might also encourage our chick to start calling as well.I gave the owner as much information as possible and headed home to see what news the night might bring.
A nervous night to be sure，but sometimes the spirits of nature smile on us all！ The homeowner called to say that the parents had responded
to the recordings.I drove over and saw the chick in the nest looking healthy and active.And it was accompanied in the nest by the greatest sight of all—LUNCH ！ The parents had done their duty and would probably continue to do so.
