Section   A

      I work with Volunteers for Wildlife, arescue and education organization at Bailey Arboretum in Locust Valley. Tryingto help injured, displaced or sick creatures can be heartbreaking; survival isnever certain. However, when it works, it is simply beautiful.

       I got a rescue call from a woman inMuttontown. 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 hadalready zxxk.been placed in a carrier for safety.

       I examined the chick(雏鸟) and it seemed fine. If I couldlocate the nest, I might have been able to put it back, but no luck. My nextwork was to construct a nest and anchor it in a tree.

       The homeowner was very helpful. A wirebasket was found. I put some pine branches into the basket to make this nestsafe and comfortable. I placed the chick in the nest, and it quickly calmeddown.

       Now all that was needed were the parents,but they were absent. I gave the homeowner a recording of the hunger screams ofowl chicks. These advertise the presence of chicks to adults; they might alsoencourage our chick to start calling as well. I gave the owner as muchinformation as possible and headed home to see what news the night might bring.

       A nervous night to be sure,but sometimesthe spirits of nature smile on us all! The homeowner called to say that theparents had responded to the recordings. I drove over and saw the chick in thenest looking healthy and active. And it was accompanied in the nest by thegreatest sight of all — LUNCH！The parents had done their duty and would probably continue to doso.
