Both man-made and nature-made birds should benefit from $6.25 million in grants the Federal Aviation Administration gave to four Utah airports this week.

      The largest grant - $5.73 million - went to the Salt Lake International Airport to develop an "airport wetlands mitigation area," for adjacent Great Salt Lake marshes that are the homes of many birds.The money to three other Utah airports went to help the jet- and propeller-driven types of birds.

      Beaver Municipal Airport received $425,144 to rehabilitate and extend its runway, and install visual approach aid headquarters.

      Cedar City Municipal Airport received $63,658 and Heber Valley Airport received $41,969, both to conduct master plan studies. The grants were announced by Sen. Orrin Hatch, R-Utah.
