Six words have had their birds removed. The birds have been placed into Group A. The remaining letters of each word have been placed into Group B. Your task is to reconstitute the words by merging each bird with the proper set of letters. Other than merging the two groups together, there is no rearranging of the letters. Example: sand + pne = spanned (SpANneD).
Group A: crow, hawk, owl, raven, robin, wren
Group B: itt, ndior, ossb, tre, trsig, tulg
crow + ossb = crossbow (CRossbOW)
hawk + ndior = handiwork (HAndiWorK)
owl + tre = trowel (trOWeL)
raven + trsig = traversing (tRAVErsiNg)
robin + tulg = troubling (tROuBlINg)
wren + itt = written (WRittEN)
